Systolic controlled, diastolic not

**My Thought Process for Evaluating the QM-CBP Measure**

Alright, let's break down this member's evaluation against the QM-CBP measure. My primary goal here is to determine if they are compliant for the 2026 measure year, which runs from January 1st to December 31st, 2026.

First, I need to establish the member's basic eligibility. The member was born on January 17th, 1963. As of the end of the measure year, December 31st, 2026, they will be 63 years old (2026 - 1963 = 63). This falls squarely within the 18-85 age range required for this measure, so that's good.

Next, I'll look at their enrollment. They were continuously enrolled from January 1st, 2026, through December 31st, 2026. This satisfies the continuous enrollment requirement – no gaps to worry about.

Now, for the core of the measure: the qualifying event. The QM-CBP requires an outpatient encounter with an I10 diagnosis between January 1st and June 30th, 2026. I found an office visit on March 4th, 2026, with a diagnosis of I10. Perfect, that fulfills the event requirement.

Before moving to the numerator, I must check for any exclusions. I've reviewed the record and confirmed there are no signs of End-Stage Renal Disease (ESRD) or dialysis, pregnancy, hospice care, or death within the measure period. So, no exclusions apply, which means the member *could* be compliant if the numerator is met.

Now, the crucial part: the numerator. This requires the most recent outpatient blood pressure (BP) reading taken on or after the qualifying hypertension encounter (March 4th, 2026) and on or before December 31st, 2026. I have two readings to consider:
*   March 4th, 2026: BP 150/94
*   October 14th, 2026: BP 134/92

The most recent reading is from October 14th, 2026, with a BP of 134/92. The requirement for compliance here is *both* systolic < 140 AND diastolic < 90.

Let's evaluate the October 14th reading:
*   Systolic: 134. This is indeed less than 140. That part of the condition is met.
*   Diastolic: 92. This is *not* less than 90. This part of the condition is *not* met.

Since both systolic *and* diastolic values must be below the specified thresholds, this member fails the numerator requirement because their diastolic pressure of 92 is not below 90.

Therefore, the member's status is "non_compliant".

The reason for non-compliance is directly related to that last BP reading. I need to clearly state what went wrong. My reasoning is: "The most recent blood pressure reading on 2026-10-14 had a diastolic of 92, which is not below the required 90 threshold." This is concise and accurate, directly pointing to the failure.

Finally, I need to ensure I'm outputting the correct keys. The instructions specify "status" and "reason" for QM-CBP, and importantly, *not* the `met_7_day` and `met_30_day` keys which are for QM-FUM. My JSON output will reflect this.

Everything seems to align. The age is right, enrollment is continuous, a qualifying encounter exists, no exclusions apply, but the numerator is not met due to the diastolic reading.

Here's the final JSON reflecting my conclusion:

```json
{
  "status": "non_compliant",
  "reason": "The most recent blood pressure reading on 2026-10-14 had a diastolic of 92, which is not below the 90 threshold."
}
```

**My Thought Process for Evaluating Member 40115 Against QM-CBP for 2026**

My primary objective here is to determine the compliance status of member 40115 for the Blood Pressure Control in Hypertension (QM-CBP) measure for the 2026 measurement year. I need to meticulously check their eligibility and whether they meet the numerator criteria, while also ensuring no exclusion criteria apply. The final output should be in a specific JSON format, including "status" and "reason" keys, and importantly, I must avoid adding any extraneous keys.

First, I'll establish the **Eligible Population (Denominator)**.
*   **Age:** The member needs to be between 18 and 85 as of December 31, 2026. Their Date of Birth is January 17, 1963. So, on December 31, 2026, they will be 63 years old (2026 - 1963 = 63). This falls perfectly within the 18-85 age range, so they meet this criterion.
*   **Event:** They must have had at least one outpatient encounter with a hypertension diagnosis (ICD-10 code I10) between January 1, 2026, and June 30, 2026. My records show an office visit on March 4, 2026, with diagnosis I10. This date is within the specified window, so they meet the event criterion.
*   **Continuous Enrollment:** The member must have been enrolled for the entire measurement year, with no more than one gap of up to 45 days. The records indicate continuous enrollment from January 1, 2026, through December 31, 2026. This means they meet the continuous enrollment criterion.

Next, I'll assess the **Required Exclusions**.
*   **E1 (ESRD/dialysis):** I've checked the records and there's no indication of End-Stage Renal Disease or dialysis.
*   **E2 (Pregnancy):** There's no mention of pregnancy in the member's record.
*   **E3 (Hospice/palliative care):** The member is not enrolled in hospice or receiving palliative care.
*   **E4 (Died):** The member is alive.

Since none of the exclusion criteria are met, the member remains in the eligible population.

Now, I'll move on to the **Numerator**. This is where I need to be very precise. The member must have had their most recent outpatient blood pressure reading, taken on or after their qualifying hypertension encounter (March 4, 2026) and on or before December 31, 2026, be *below 140 systolic* AND *below 90 diastolic*. Both conditions must be met simultaneously.

Let's examine the recorded blood pressure readings:
*   **March 4, 2026:** BP was 150/94.
*   **October 14, 2026:** BP was 134/92.

The most recent reading is the one from October 14, 2026.
*   **Systolic:** The systolic reading is 134. Is 134 below 140? Yes, it is.
*   **Diastolic:** The diastolic reading is 92. Is 92 below 90? No, it is not.

Since the diastolic reading (92) is not below the threshold of 90, the member does not meet the numerator criteria.

Therefore, their status is **"non_compliant"**.

The **reason** for non-compliance needs to be clearly stated, adhering to the prompt's requirements. The most recent blood pressure reading on October 14, 2026, had a diastolic value of 92, which is not below the 90 threshold. This is concise (22 words) and accurately reflects the issue.

Finally, I must ensure the output adheres to the specified JSON format. The required keys are "status" and "reason". I also need to be mindful of the prompt's instruction regarding QM-FUM keys – since this measure is QM-CBP and not QM-FUM, I will *not* include "met_7_day" or "met_30_day" keys, as they are explicitly not asked for in this context. The instruction "Include every required key. Do not add keys that were not asked for" is paramount here.

So, the JSON output will be:
```json
{
  "status": "non_compliant",
  "reason": "The most recent blood pressure reading on 2026-10-14 had a diastolic value of 92, which is not below the 90 threshold."
}
```
I've double-checked all conditions: age is correct, event date is correct and within the window, continuous enrollment is met, no exclusions apply, and the numerator criteria specifically regarding the diastolic reading on the most recent BP measurement were not satisfied. The JSON structure is also correct.

**My Thought Process for Evaluating Member 40115 for QM-CBP (Blood Pressure Control in Hypertension)**

Alright, let's break down the evaluation for Member ID 40115 regarding the QM-CBP measure for blood pressure control in hypertension. This measure covers the measurement year from January 1, 2026, to December 31, 2026.

First, I need to confirm if this member belongs in the denominator for this measure. I've got their details: born January 17, 1963. As of the end of the measurement year, December 31, 2026, they'd be 63 years old (2026 - 1963 = 63). This falls squarely within the eligible age range of 18 to 85. Crucially, they were continuously enrolled throughout the entire measurement year, from January 1, 2026, to December 31, 2026, with no gaps. This continuous enrollment is essential.

Next, I need to check for the qualifying hypertension diagnosis. The requirement is at least one outpatient encounter with diagnosis code I10 between January 1, 2026, and June 30, 2026. I see that on March 4, 2026, the member had an office visit that was coded with diagnosis I10. Perfect, that meets this requirement, placing them in the denominator.

Now, I need to check for any exclusion criteria. The potential exclusions are ESRD/Dialysis (E1), Pregnancy (E2), Hospice/Palliative Care (E3), and Death (E4). My review shows no mention of dialysis, no indication of pregnancy, no hospice or palliative care, and the member was alive at the end of the year. So, the member is *not* excluded from the measure.

With the member confirmed in the denominator and not excluded, the focus shifts to the numerator – the blood pressure control itself. The requirement here is that the *most recent* outpatient blood pressure reading, taken on or after the date of the qualifying hypertension encounter (which was March 4, 2026) and on or before December 31, 2026, must be below the threshold of 140 systolic AND below 90 diastolic.

Let's look at the readings:
1.  On March 4, 2026 (the same day as the qualifying encounter), there was an outpatient office visit with a BP of 150/94.
2.  Later, on October 14, 2026, there was another outpatient office visit with a BP of 134/92.

The most recent reading is clearly the one from October 14, 2026: 134/92. Now, I need to evaluate this against the threshold:
*   Systolic: 134. Is 134 < 140? Yes, that component passes.
*   Diastolic: 92. Is 92 < 90? No, that component fails.

The rule states *both* components must be below the threshold. Since the diastolic pressure of 92 is not below 90, the member has not met the numerator requirement.

Therefore, the member is `non_compliant`.

The specific reason for non-compliance, as I've formulated it, is: "The most recent blood pressure reading of 134/92 on 2026-10-14 has a diastolic value that is not below 90." This concisely explains why the numerator was not met. I've considered a few phrasing options, and this one seems clear and direct, hitting the key detail about the diastolic reading. I've double-checked that no QM-FUM keys are needed here; the `status` and `reason` are sufficient.

**My Thought Process for Evaluating Member 40115 Against the QM-CBP Measure**

As I approach this, my primary goal is to meticulously assess member 40115 against the Quality Measure: Blood Pressure Control in Hypertension (QM-CBP) for the measurement year 2026. My focus will be on determining their compliance status and providing a concise, accurate reason if they are not compliant.

First, I need to confirm the member's basic eligibility. The measurement period is the entirety of 2026. The member was born on January 17, 1963. This means that as of December 31, 2026, they will be 63 years old (2026 - 1963 = 63). This falls squarely within the eligible age range of 18 to 85 for this measure. Their enrollment is continuous throughout 2026, with no gaps, which is another crucial eligibility criterion.

Next, I need to establish if the member had a qualifying event for hypertension. The measure specifies "at least one outpatient encounter with diagnosis I10 between 2026-01-01 and 2026-06-30." I see a record for "2026-03-04: Office visit, diagnosis I10." This perfectly matches the criteria, so this encounter will serve as our qualifying event.

Then, I must check for any exclusion criteria. The measure lists: E1 (ESRD/Dialysis), E2 (Pregnancy), E3 (Hospice/Palliative), and E4 (Death). My review of the available data indicates none of these exclusions apply to this member. Therefore, the member is considered "in the denominator" and is eligible for numerator assessment.

The core of the compliance determination lies in the numerator. The QM-CBP measure requires the "most recent outpatient BP reading on or after the qualifying hypertension encounter (2026-03-04) and before 2026-12-31." I need to identify all outpatient blood pressure readings within this specific timeframe and select the latest one.

Looking at the data, I have two potential readings for blood pressure:
1.  On the qualifying encounter date itself, 2026-03-04, the BP was 150/94.
2.  Later in the year, on 2026-10-14, there was another BP reading of 134/92.

The reading on 2026-10-14 is indeed the most recent outpatient BP reading within the specified window. Now, I must compare this reading (134/92) against the numerator's threshold: "Below 140 systolic AND below 90 diastolic."

Let's break this down:
*   **Systolic:** Is 134 below 140? Yes, it is.
*   **Diastolic:** Is 92 below 90? No, it is not.

Since the diastolic reading of 92 *fails* to meet the "below 90" requirement, the member does not meet the numerator criteria. Consequently, the member is "non_compliant."

Finally, I need to articulate the "reason" for this non-compliance. It must be concise, under 30 words, and clearly explain the failure. The issue is the diastolic pressure.

Therefore, I will construct the reason as: "The most recent blood pressure reading of 134/92 on 2026-10-14 is not compliant because the diastolic value of 92 is not below 90." This clearly and accurately states the failure point.

I also note that the instructions mention that "Items drawn from measure QM-FUM require two further keys..." but this task is specifically about QM-CBP, so I will *not* include keys like "met_7_day" or "met_30_day" as they are not applicable to this measure. The relevant keys I will output are "status" and "reason".

In summary, my final output will reflect:
*   `status`: "non_compliant"
*   `reason`: "The most recent blood pressure reading of 134/92 on 2026-10-14 is not compliant because the diastolic value of 92 is not below 90."

**Analysis of QM-CBP Measure for Member 40115**

My task is to assess member 40115 against the QM-CBP (Blood Pressure Control in Hypertension) measure for the measurement year 2026. I need to determine their compliance based on the provided data and then output the result in a specific JSON format.

First, I'll verify the member's eligibility for the measure.

*   **Measurement Period:** The measurement year is 2026, specifically from January 1, 2026, to December 31, 2026.
*   **Member Identification:** The member is 40115, born January 17, 1963.
*   **Age Eligibility:** As of December 31, 2026, the member will be 63 years old (2026 - 1963 = 63). The measure requires members to be between 18 and 85 years old. Since 63 falls within this range, the member meets the age criterion.
*   **Qualifying Hypertension Event:** The measure requires at least one outpatient encounter with a diagnosis of hypertension (ICD-10 code I10) between January 1, 2026, and June 30, 2026. The member's record shows an office visit (which is an outpatient encounter) on March 4, 2026, with diagnosis I10. This encounter falls within the specified window, so the member qualifies for the denominator.
*   **Continuous Enrollment:** The measure requires continuous enrollment for the full measurement year, with no more than one gap of up to 45 days. The member's record indicates enrollment from January 1, 2026, through December 31, 2026, which is continuous and thus meets this criterion.
*   **Exclusions:** I need to check for any exclusion criteria that would make the member ineligible.
    *   **E1 (ESRD/Dialysis):** There's no indication of End-Stage Renal Disease (N18.6) or dialysis (Z99.2) on or before December 31, 2026.
    *   **E2 (Pregnancy):** There's no indication of pregnancy during 2026.
    *   **E3 (Hospice/Palliative Care):** There's no indication of hospice or palliative care during 2026.
    *   **E4 (Death):** There's no indication that the member died during 2026.
    Since none of the exclusion criteria are met, the member is considered eligible.

Now, I will assess the numerator for compliance.

*   **Numerator Requirement:** The measure requires the most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter (March 4, 2026) and on or before December 31, 2026, to be below 140 systolic AND below 90 diastolic.
*   **Available Readings:**
    1.  March 4, 2026: Blood Pressure reading of 150/94 mmHg (This was from the qualifying encounter itself).
    2.  October 14, 2026: Blood Pressure reading of 134/92 mmHg (This was from an office visit, hence an outpatient reading).
*   **Identifying the Most Recent Reading:** Comparing the dates, the reading on October 14, 2026, is the most recent outpatient reading on or after the qualifying encounter date (March 4, 2026) and within the measurement year.
*   **Checking Thresholds:**
    *   **Systolic Pressure:** The reading is 134 mmHg. The threshold is *below* 140 mmHg. 134 is indeed below 140. (Pass)
    *   **Diastolic Pressure:** The reading is 92 mmHg. The threshold is *below* 90 mmHg. 92 is *not* below 90. (Fail)

Since *both* systolic and diastolic pressures must be below their respective thresholds, and the diastolic pressure (92) fails to meet the *below 90* requirement, the member does not meet the numerator criteria.

Therefore, the member's status is `non_compliant`.

The reason for non-compliance, as per the instructions, should be a concise statement of the specific criterion that was not met. In this case, it's the diastolic blood pressure reading.

*   **Reason Formulation:** "The most recent diastolic blood pressure reading of 92 on 2026-10-14 is not below the required threshold of 90." This is a single sentence, under 30 words, and clearly identifies the failing criterion and the specific reading.

Finally, I need to ensure the output is in the correct JSON format, which for QM-CBP only requires "status" and "reason" keys.

```json
{
  "status": "non_compliant",
  "reason": "The most recent diastolic blood pressure reading of 92 on 2026-10-14 is not below the required threshold of 90."
}
```

Alright, let's break down my thought process for evaluating this member against the QM-CBP quality measure.

My primary task is to determine if Member 40115 is compliant with the QM-CBP standard, which essentially boils down to checking if their blood pressure is adequately controlled for hypertension. To do this, I need to meticulously go through several stages: first, understanding the member's specific data, then seeing if they even qualify to be part of the group we're measuring (the denominator), then checking if there are any reasons to exclude them from the measurement despite qualifying for the denominator, and finally, determining if they met the actual performance criteria (the numerator).

**1. Initial Member Data Analysis:**
I started by pulling together all the provided information about Member 40115.
*   **Who:** Member ID 40115.
*   **When born:** January 17, 1963.
*   **Gender:** Male.
*   **Coverage:** Enrolled continuously throughout the entire measurement year, 2026, from January 1st to December 31st. This is a key point for the continuous enrollment requirement.
*   **Medical Encounters:**
    *   A visit on March 4, 2026, where they were diagnosed with hypertension (ICD-10 code I10) and their blood pressure was recorded as 150/94.
    *   Another visit on October 14, 2026, also with a hypertension diagnosis (I10), and their BP was 134/92.
*   **Exclusions:** The record explicitly states no hospice, no palliative care, no pregnancy, no dialysis, and no End-Stage Renal Disease (ESRD). Crucially, the member was alive at the end of the measurement year. These are all important flags for potential exclusions.

**2. Evaluating Against QM-CBP Specification - The Denominator:**
Now, I need to confirm if this member belongs in the group we're measuring against. This means meeting the criteria for the denominator.

*   **Age:** The measure is for adults aged 18-85. The member was born in 1963. By the end of the measurement year, December 31, 2026, they would be 2026 - 1963 = 63 years old. Since 63 falls squarely within the 18-85 range, this criterion is met.
*   **Qualifying Event (Hypertension Encounter):** The denominator requires "at least one outpatient encounter with a hypertension diagnosis (I10) on or between January 1, 2026, and June 30, 2026." Looking at the encounters, the member had a visit on March 4, 2026, with a diagnosis of I10. This was an outpatient visit and falls within that crucial first half of the year. So, this criterion is met.
*   **Continuous Enrollment:** The measure requires enrollment for the *full* measurement year (or with a very minor gap). The member's record states "2026-01-01 through 2026-12-31, continuous." This is a perfect fit. This criterion is met.

Since all three denominator criteria are satisfied, I've confirmed that Member 40115 is indeed part of the population we need to evaluate.

**3. Checking for Required Exclusions:**
Next, I need to see if there's any reason to exclude this member from the measurement, even though they are in the denominator. The standard usually lists specific conditions that exempt a member.

*   **E1 (ESRD/Dialysis):** The record explicitly states "No dialysis." This suggests no ESRD diagnosis (like N18.6) either. So, this exclusion does not apply.
*   **E2 (Pregnancy):** The record clearly states "No pregnancy." This exclusion does not apply.
*   **E3 (Hospice/Palliative Care):** The record mentions "No hospice." I'm assuming this also implies no palliative care services relevant to the exclusion criteria. This exclusion does not apply.
*   **E4 (Death):** The record confirms "Member alive at year end." This exclusion does not apply.

Since none of the specified exclusions apply, this member remains in the measurement set.

**4. Evaluating Against the Numerator:**
This is where we determine if the member actually met the quality goal. The numerator requires: "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before December 31, 2026, is below 140 systolic AND below 90 diastolic."

*   **Qualifying Encounter Date:** The qualifying hypertension encounter occurred on March 4, 2026.
*   **Relevant BP Readings:** I need to look at all outpatient BP readings from March 4, 2026, up to the end of the year (December 31, 2026).
    *   Reading 1: March 4, 2026: 150/94.
    *   Reading 2: October 14, 2026: 134/92.
*   **Most Recent Reading:** The most recent of these is the one from October 14, 2026: 134/92.
*   **Checking Against Numerator Criteria:**
    *   **Systolic:** Is 134 < 140? Yes. This part is met.
    *   **Diastolic:** Is 92 < 90? No. This part is **not** met.
*   **The "AND" condition:** The rule states "below 140 systolic AND below 90 diastolic." This means *both* conditions must be true. Since the diastolic pressure of 92 is not below 90, the numerator criteria are not met.

**5. Conclusion and Rationale:**
Putting it all together:
*   The member is in the denominator.
*   The member is not excluded.
*   The member did *not* meet the numerator criteria.

Therefore, my conclusion is that the member is **non_compliant**.

The specific reason is that their most recent blood pressure reading, 134/92, while having a systolic pressure below 140, had a diastolic pressure of 92, which is not below the required threshold of 90 mmHg.

Finally, I'll format this into the requested JSON structure, confirming that `{"status": "non_compliant", "reason": "The member's most recent blood pressure reading had a diastolic value of 92, which is not below the 90 mmHg threshold."}` accurately reflects my findings. This entire process, from data extraction to rule application, leads me to this precise conclusion.

Alright, let's break down this quality measure and how this specific member fits into it. My thought process goes like this:

First, I need to deeply understand the requirements of the QM-CBP measure itself. What are the parameters for eligibility, and what defines success?

*   **The Measure:** It's about Blood Pressure Control in Hypertension. Simple enough.
*   **The Timeframe:** We're looking at the measurement year, specifically from January 1st, 2026, to December 31st, 2026.
*   **Who's Even Eligible (Denominator)?**
    *   They need to be between 18 and 85 years old by the end of 2026.
    *   They must have had at least one outpatient visit where hypertension (I10) was diagnosed, and this visit must have occurred in the first half of 2026 (January 1st to June 30th).
    *   Crucially, they need to have been continuously enrolled for the *entire* year, or at least with no more than one gap of 45 days or less.
*   **What Makes Them Compliant (Numerator)?**
    *   After that qualifying encounter (the one in the first half of the year), their *most recent* outpatient blood pressure reading, taken before the end of 2026, needs to be less than 140 systolic *and* less than 90 diastolic.
    *   Important note: Readings from Emergency Departments or inpatient stays don't count for this numerator.
    *   If there isn't a qualifying reading after the event and before year-end, they're automatically non-compliant.
*   **Who Do We Exclude?** There are specific conditions that take a member out of consideration altogether:
    *   End-stage renal disease (ESRD) or dialysis by the end of 2026.
    *   Pregnancy at any point in 2026.
    *   Receiving hospice or palliative care during 2026.
    *   Dying during 2026.

Now, I'll move on to the specific member I'm evaluating – MEMBER 40115. I need to see how their individual data stacks up against those measure specifications.

*   **Member Details:**
    *   Date of Birth: January 17th, 1963.
    *   Sex: Male.
    *   Enrolment: They were continuously enrolled from January 1st, 2026, through December 31st, 2026. That's a full year, no gaps.
    *   Encounters:
        *   March 4th, 2026: An office visit, diagnosis I10, and the BP reading was 150/94.
        *   October 14th, 2026: Another office visit, diagnosis I10, and the BP reading was 134/92.
    *   Other crucial info: No mention of hospice, pregnancy, or dialysis. And they were alive at the end of the year.

Next, I'll systematically check if this member meets the denominator criteria.

*   **Age Check:** Born 1963-01-17. On 2026-12-31, they will be 63 years old (2026 - 1963). 63 is well within the 18-85 range. **Yes, they meet the age requirement.**
*   **Event Check:** Did they have an outpatient encounter with I10 between Jan 1st and June 30th, 2026? Yes, the March 4th, 2026 visit with dx I10 fits perfectly. **Yes, they meet the event requirement.**
*   **Continuous Enrolment Check:** Enrolled 2026-01-01 to 2026-12-31, continuously. This directly matches the requirement for a full year with no significant gaps. **Yes, they meet the enrolment requirement.**

So, based on these checks, MEMBER 40115 is definitely in the eligible population – they're in the denominator.

Now, I need to see if any of the exclusion criteria apply. If any of these are met, they're out of the picture for this measure, regardless of their BP readings.

*   **ESRD/Dialysis (E1):** The record states "No dialysis." **Not excluded.**
*   **Pregnancy (E2):** They are male, and the record says "No pregnancy." **Not excluded.**
*   **Hospice/Palliative (E3):** The record states "No hospice." **Not excluded.**
*   **Death (E4):** The record states "Member alive at year end." **Not excluded.**

Excellent, this member is not excluded from the measure. Now, the critical part: do they meet the numerator criteria for compliance?

*   **Numerator Rule:** The most recent *outpatient* BP reading, taken *after* their qualifying encounter (March 4th, 2026) and *before* the end of the year (December 31st, 2026), must be < 140 systolic AND < 90 diastolic.
*   **Identifying the Readings:**
    *   The qualifying encounter was on 2026-03-04, with a BP of 150/94. This is within the date range.
    *   The next (and most recent) outpatient reading after that, and before year-end, was on 2026-10-14, with a BP of 134/92.
*   **Evaluating the Most Recent Reading (134/92):**
    *   Systolic: Is 134 < 140? Yes, that part is met.
    *   Diastolic: Is 92 < 90? No, that part is not met.
*   **Conclusion on Compliance:** Since the rule requires *both* systolic and diastolic to be below the thresholds, and the diastolic reading failed, this member does not meet the numerator criteria.

Therefore, my final determination for MEMBER 40115 is that they are **non-compliant**.

The specific reason for this non-compliance is: Their most recent blood pressure reading on October 14th, 2026, was 134/92. While the systolic pressure (134) was within the target range (<140), the diastolic pressure (92) was not below the required threshold of 90 mmHg.

To represent this in the requested JSON format:

```json
{
  "status": "non_compliant",
  "reason": "The member's most recent diastolic blood pressure reading of 92 mmHg was not below the 90 mmHg threshold required for compliance."
}
```

I've double-checked my logic and calculations – the age, event, enrolment, and exclusion criteria are all correctly applied. The crucial part is the numerator evaluation, and the most recent reading of 134/92 clearly fails the diastolic component. The reason statement is concise and accurately points to the exact value and threshold that caused the non-compliance.

Alright, let's break down my thought process for evaluating MEMBER 40115 against the QM-CBP quality measure. My primary objective here is to determine if this member meets the criteria for blood pressure control.

First, I need to thoroughly understand the specifications of the QM-CBP measure itself. This means I'm meticulously dissecting each component:
*   **The Measure:** It's about Blood Pressure Control in Hypertension. Straightforward enough.
*   **The Measurement Year:** The timeframe is clearly defined from January 1, 2026, to December 31, 2026. This is my sandbox.
*   **The Denominator (Who's Eligible?):** This is crucial.
    *   **Age:** The member must be between 18 and 85 years old as of the end of the measurement year (December 31, 2026).
    *   **The Trigger Event:** They need at least one outpatient encounter where hypertension (diagnosis code I10) was recorded between January 1, 2026, and June 30, 2026. This is the qualifying event.
    *   **Continuous Enrollment:** They must have been continuously enrolled throughout the *entire* measurement year, with the allowance for one short break of no more than 45 days. This ensures we have a consistent picture.
*   **The Numerator (Who Met the Goal?):** This is where compliance is assessed.
    *   **The Reading:** We're looking for the *most recent* outpatient blood pressure reading.
    *   **Timing:** This reading must have occurred on or after the qualifying encounter (the one that put them in the denominator) and before the end of the measurement year (December 31, 2026).
    *   **The Target:** Critically, this reading must be strictly less than 140 systolic *and* strictly less than 90 diastolic. Both conditions must be met.
    *   **Exclusions from Numerator:** Important to note that emergency department (ED) or inpatient readings don't count for this numerator.
*   **The Exclusions (Who's Not Included Regardless?):** Even if they meet the denominator, certain conditions automatically disqualify them from being measured.
    *   **E1:** End-Stage Renal Disease (ESRD, N18.6) or dialysis (Z99.2) by the end of the measurement year.
    *   **E2:** Pregnancy at any point during 2026.
    *   **E3:** Receiving hospice or palliative care during 2026.
    *   **E4:** Passing away during 2026.

Once I have the measure's blueprint firmly in my mind, I shift my focus to the specific member's record, MEMBER 40115. I'll go through each piece of provided information:
*   **Date of Birth (DOB):** January 17, 1963.
*   **Enrollment Status:** January 1, 2026, through December 31, 2026, and it's noted as continuous. This is a key piece for the denominator.
*   **Encounters:**
    *   March 4, 2026: An office visit with diagnosis I10 and a blood pressure reading of 150/94.
    *   October 14, 2026: Another office visit, also with diagnosis I10, and a blood pressure reading of 134/92.
*   **Other Information:** Explicitly stated: no hospice, no pregnancy, no dialysis. And the member was alive at the end of the year. This directly addresses the exclusion criteria.

Now, the real work begins: **evaluating the member against the criteria, step by step.**

**Denominator Check:**
1.  **Age:** Member's DOB is 1963-01-17. As of 2026-12-31, they would be 63 years old (2026 - 1963 = 63). Since 63 falls squarely between 18 and 85, the **age criterion is met.**
2.  **Enrolment:** The record states continuous enrollment from 2026-01-01 to 2026-12-31. This perfectly aligns with the full measurement year requirement and implies no significant gaps. The **enrolment criterion is met.**
3.  **Event:** The member needs an outpatient encounter with diagnosis I10 between January 1, 2026, and June 30, 2026. They had an encounter on March 4, 2026, with diagnosis I10. This date is within the required window. The **event criterion is met.**

My conclusion for the denominator is clear: MEMBER 40115 is eligible for evaluation. They are not "not_eligible."

**Exclusion Check:**
I'll systematically go through each exclusion criterion, cross-referencing it with the "Other info" provided:
*   **E1 (ESRD/Dialysis):** The "Other info" states "No dialysis." **Exclusion does not apply.**
*   **E2 (Pregnancy):** The "Other info" states "No pregnancy." **Exclusion does not apply.** (And given the DOB, it's highly unlikely anyway, but the explicit statement confirms it).
*   **E3 (Hospice/Palliative):** The "Other info" states "No hospice." **Exclusion does not apply.**
*   **E4 (Death):** The "Other info" states "Member alive at year end." **Exclusion does not apply.**

My conclusion for exclusions is also clear: this member is not excluded from the measure. Their status is not "excluded."

**Numerator Check (The Crucial Compliance Step):**
This is where I determine if they met the goal.
1.  **Identify the Most Recent Reading:** I need the *most recent outpatient blood pressure reading* that occurred *on or after* the qualifying encounter (March 4, 2026) and *before* December 31, 2026.
    *   Encounter 1: March 4, 2026 - BP 150/94.
    *   Encounter 2: October 14, 2026 - BP 134/92.
    The October 14th reading is the most recent one that meets the timing criteria.
2.  **Evaluate Against Target:** The target is systolic < 140 AND diastolic < 90.
    *   **Systolic:** The reading is 134. Is 134 < 140? **Yes.**
    *   **Diastolic:** The reading is 92. Is 92 < 90? **No.**

Since *both* conditions must be met, and the diastolic pressure of 92 is *not* below 90, the member has **not met the numerator criteria.**

**Final Status Determination:**
The member is in the denominator, they are not excluded, but they did not meet the numerator criteria. Therefore, their final status is `non_compliant`.

**Reasoning for Non-Compliance:**
The specific reason they are non-compliant is the diastolic blood pressure reading. I need to articulate this concisely. The diastolic component of their most recent blood pressure reading was 92, which is not below the required threshold of 90.

**Constructing the Output (JSON):**
Based on my findings:
*   `"status": "non_compliant"`
*   `"reason": "The member's most recent diastolic blood pressure reading of 92 was not below the required threshold of 90."`

I've double-checked this against the measure specifications and the member's data, and it holds up. The reason is precise and within any implied length constraints.

Let me analyze this member against the QM-CBP measure specification.

**Eligible Population (denominator):**
- Age: DOB 1963-01-17. As of 2026-12-31, age = 63. ✓ (18-85)
- Event: Office visit with I10 diagnosis on 2026-03-04, which is between 2026-01-01 and 2026-06-30. ✓
- Continuous enrolment: 2026-01-01 through 2026-12-31, continuous. ✓

Member is in the denominator.

**Exclusions:**
- E1: No ESRD or dialysis. ✗
- E2: No pregnancy. ✗
- E3: No hospice/palliative. ✗
- E4: Alive at year end. ✗

No exclusions apply.

**Numerator:**
Most recent outpatient BP reading on or after the qualifying encounter date (2026-03-04) and on or before 2026-12-31.

The qualifying encounter is 2026-03-04 (BP 150/94). The most recent BP reading after that is 2026-10-14 (BP 134/92).

Check: below 140 systolic AND below 90 diastolic.
- Systolic: 134 < 140 ✓
- Diastolic: 92 < 90 ✗

Both components must be below the threshold. Diastolic 92 is not below 90.

So the member does NOT meet the numerator.

**Status: non_compliant**

Reason: The most recent qualifying BP reading (2026-10-14) was 134/92; diastolic 92 does not meet the below-90 threshold.

Let me evaluate this member against QM-CBP.

**ELIGIBLE POPULATION (denominator)**

1. **Age**: DOB 1963-01-17. As of 2026-12-31, age = 2026 - 1963 = 63 years. 18 through 85 — YES.

2. **Event**: At least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30.
   - 2026-03-04: Office visit, diagnosis I10. This is within the window. YES.

3. **Continuous enrolment**: Enrolled 2026-01-01 through 2026-12-31, continuous. No gaps. YES.

Member is in the denominator.

**REQUIRED EXCLUSIONS**

- E1: No ESRD or dialysis. NO.
- E2: No pregnancy. NO.
- E3: No hospice or palliative care. NO.
- E4: Alive at year end. NO.

No exclusions apply. Member remains in the denominator.

**NUMERATOR**

The most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31.

Qualifying hypertension encounter: 2026-03-04.

BP readings on or after 2026-03-04 and on or before 2026-12-31:
- 2026-03-04: BP 150/94 (office visit — outpatient)
- 2026-10-14: BP 134/92 (office visit — outpatient)

Most recent: 2026-10-14, BP 134/92.

Check: Below 140 systolic AND below 90 diastolic.
- Systolic: 134 < 140 — YES
- Diastolic: 92 < 90 — NO (92 is NOT below 90)

The most recent reading does NOT meet the numerator criteria because diastolic is 92, which is not below 90.

So the member is in the denominator, not excluded, and does NOT meet the numerator.

Status: non_compliant
Reason: Most recent BP reading (2026-10-14) had diastolic 92, which is not below 90.

Let me evaluate this member against the QM-CBP measure specification.

**Step 1: Eligible Population (Denominator)**

- **Age**: DOB 1963-01-17. As of 2026-12-31, age = 63 years. This is between 18 and 85. ✓
- **Event**: At least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30.
  - 2026-03-04: Office visit, diagnosis I10. This is an outpatient encounter with I10 before 2026-06-30. ✓
- **Continuous enrolment**: Enrolled 2026-01-01 through 2026-12-31, continuous. No gaps. ✓

Member is in the denominator.

**Step 2: Exclusions**

- E1: No dialysis, no ESRD mentioned. ✓ (not excluded)
- E2: No pregnancy. ✓ (not excluded)
- E3: No hospice or palliative care. ✓ (not excluded)
- E4: Member alive at year end. ✓ (not excluded)

No exclusions apply. Member remains in the denominator.

**Step 3: Numerator**

The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31.

Readings:
- 2026-03-04: Office visit, BP 150/94 (this is on or after the qualifying encounter date)
- 2026-10-14: Office visit, BP 134/92 (this is the most recent)

Most recent reading: 2026-10-14, BP 134/92.

Numerator requires: below 140 systolic AND below 90 diastolic.
- Systolic: 134 < 140 ✓
- Diastolic: 92 < 90? No, 92 is NOT below 90. ✗

The diastolic is 92, which is not below 90. So the member does NOT meet the numerator.

**Result**: non_compliant

Reason: Most recent BP reading (134/92 on 2026-10-14) has diastolic 92, which is not below the 90 threshold.

Let me evaluate this member against the QM-CBP measure specification.

**Step 1: Check eligible population (denominator)**

- **Age**: DOB is 1963-01-17. As of 2026-12-31, age = 2026 - 1963 = 63 years old (turns 63 in January 2026). Age 63 is between 18 and 85. ✓
- **Event**: At least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. The member has an office visit on 2026-03-04 with diagnosis I10. This is within the window. ✓
- **Continuous enrolment**: Enrolled 2026-01-01 through 2026-12-31, continuous. No gaps. ✓

The member is in the denominator.

**Step 2: Check exclusions**

- E1: No ESRD (N18.6) or dialysis (Z99.2). ✓ (not excluded)
- E2: No pregnancy. ✓ (not excluded)
- E3: No hospice or palliative care. ✓ (not excluded)
- E4: Member alive at year end. ✓ (not excluded)

No exclusions apply.

**Step 3: Check numerator**

The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31.

The encounters are:
1. 2026-03-04: Office visit, BP 150/94
2. 2026-10-14: Office visit, BP 134/92

The most recent outpatient BP reading is 2026-10-14: BP 134/92.

For numerator compliance: systolic must be below 140 AND diastolic must be below 90.
- Systolic: 134 < 140 ✓
- Diastolic: 92 < 90? No, 92 is NOT below 90. ✗

Both components must be below the threshold. Diastolic is 92, which is not below 90. So the member does NOT meet the numerator.

**Result**: The member is in the denominator, not excluded, and does not meet the numerator → "non_compliant".

**Reason**: The most recent BP reading (134/92 on 2026-10-14) has diastolic at 92, which is not below 90.

Let me work through this.

Measure QM-CBP.

Eligible population:
- Age: DOB 1963-01-17, as of 2026-12-31: age 63. Between 18 and 85. ✓
- Event: at least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. The 2026-03-04 office visit with I10 qualifies. ✓
- Continuous enrolment: enrolled full year 2026-01-01 through 2026-12-31, continuous. ✓

So member is in the denominator.

Exclusions:
- E1 ESRD/dialysis: none.
- E2 pregnancy: none.
- E3 hospice/palliative: none.
- E4 died: no, alive at year end.

No exclusions.

Numerator: The most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 must be below 140 systolic AND below 90 diastolic.

Qualifying encounter date: 2026-03-04. Readings on or after 2026-03-04 and on or before 2026-12-31:
- 2026-03-04: 150/94
- 2026-10-14: 134/92

Most recent: 2026-10-14, 134/92. Systolic 134 < 140 ✓. Diastolic 92 ≥ 90 ✗. Both components must be below threshold. Diastolic 92 is not below 90, so the member does not meet the numerator.

Status: non_compliant.

Reason: The most recent qualifying BP reading (2026-10-14) was 134/92; diastolic 92 is not below 90. Under 30 words, one sentence.

This is not QM-FUM, so no met_7_day / met_30_day keys.

Required keys: status, reason only.

Reason: "Most recent outpatient BP (2026-10-14) was 134/92; diastolic 92 is not below 90, so the numerator is not met."

Count words: Most(1) recent(2) outpatient(3) BP(4) (2026-10-14)(5) was(6) 134/92;(7) diastolic(8) 92(9) is(10) not(11) below(12) 90,(13) so(14) the(15) numerator(16) is(17) not(18) met(19). Good, under 30 words.

Let me work through this carefully.

Measure QM-CBP — Blood Pressure Control in Hypertension
Measurement year: 2026-01-01 through 2026-12-31.

Member 40115:
- DOB 1963-01-17. Age as of 2026-12-31: 2026 - 1963 = 63 years (birthday 2026-01-17, so turned 63 on 2026-01-17). Age 63 → within 18-85. ✓
- Enrolment: continuous 2026-01-01 through 2026-12-31. No gaps. ✓
- Event: outpatient encounter with I10 on or between 2026-01-01 and 2026-06-30. The 2026-03-04 office visit with I10 qualifies. ✓
- Exclusions: no ESRD/dialysis, no pregnancy, no hospice, alive at year end. None apply.

Numerator: the most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31.

Qualifying hypertension encounter: 2026-03-04 (the one in the first half of the year that establishes the event).

Readings on or after 2026-03-04 and on or before 2026-12-31:
- 2026-03-04: BP 150/94 (on the encounter date itself — "on or after the date of the qualifying encounter" — so this counts as taken on the date).
- 2026-10-14: BP 134/92.

The most recent qualifying reading is 2026-10-14: BP 134/92.

Threshold: below 140 systolic AND below 90 diastolic. Systolic 134 < 140 ✓. Diastolic 92 — NOT below 90 ✗. So the reading does not meet the numerator.

Therefore: member is in the denominator, not excluded, does not meet the numerator → "non_compliant".

Reason: most recent qualifying BP (2026-10-14) diastolic 92 ≥ 90, so fails numerator.

Note: one might be tempted to say "well, the 2026-03-04 reading had systolic 150 and diastolic 94, and the latest has diastolic 92" — but the rule says the most recent reading is used, both components must be below threshold. Diastolic 92 fails. Non-compliant.

Required keys for this task family: "status" and "reason". QM-CBP is not QM-FUM, so no met_7_day/met_30_day keys (those are required for items drawn from QM-FUM only).

Reason must be one sentence, under 30 words, naming the specific criterion or date.

Reason: "Most recent qualifying reading 2026-10-14 BP 134/92 has diastolic 92, not below 90, so numerator not met." — count words: Most(1) recent(2) qualifying(3) reading(4) 2026-10-14(5) BP(6) 134/92(7) has(8) diastolic(9) 92(10) not(11) below(12) 90(13) so(14) numerator(15) not(16) met(17). Under 30. Good.

Output: exactly one fenced JSON code block with status and reason.

Let me work through this member against QM-CBP.

Denominator:
- Age: DOB 1963-01-17, as of 2026-12-31 → age 63 (birthday 2026-01-17, turns 63). Age 63 is within 18–85. Eligible.
- Event: outpatient encounter with I10 on or between 2026-01-01 and 2026-06-30. 2026-03-04 office visit with I10 qualifies. Yes.
- Continuous enrolment: enrolled 2026-01-01 through 2026-12-31, continuous. No gaps. Eligible.

Exclusions:
- E1: no dialysis/ESRD. No.
- E2: no pregnancy. Male, and record says no.
- E3: no hospice.
- E4: alive at year end. No.
Not excluded.

Numerator: most recent outpatient BP reading on or after the qualifying hypertension encounter date and on or before 2026-12-31.

Qualifying encounter date: the event is the 2026-03-04 encounter (the one in the first half of the year). The numerator requires readings on or after the date of the qualifying hypertension encounter. Hmm — "the qualifying hypertension encounter" — is it the one that established the denominator event, or any hypertension encounter? The spec says "at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30" establishes the event. Then numerator: "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter..."

The qualifying hypertension encounter is the one that established the denominator — 2026-03-04. Readings on or after 2026-03-04 and on or before 2026-12-31: both readings qualify (2026-03-04 itself, on the date, and 2026-10-14). Most recent is 2026-10-14: BP 134/92.

Both components must be below 140 systolic AND below 90 diastolic. 134 < 140 yes; 92 < 90 no. Diastolic 92 fails. So not compliant.

Status: non_compliant.

Reason: most recent BP 134/92 on 2026-10-14, diastolic 92 ≥ 90 threshold.

Reason under 30 words, one sentence: "Most recent qualifying BP 2026-10-14 is 134/92; diastolic 92 is not below 90, so numerator not met."

Keys: status, reason. QM-CBP doesn't require met_7_day/met_30_day (those are QM-FUM only).

Output exactly one fenced JSON code block.

We need to determine status for measure QM-CBP (Blood Pressure Control in Hypertension) for Member 40115. Measurement year 2026-01-01 through 2026-12-31.

Let's parse the member record:
- DOB 1963-01-17. As of 2026-12-31, age = 2026 - 1963 = 63 years (if birthday before Dec 31? DOB Jan 17, so on Dec 31, 2026, he is 63 (since birthday Jan 17, 2026 already passed). Actually in 2026 on Jan 17 he turns 63. So age 63 as of 2026-12-31. That is within 18-85. OK.
- Enrolment: 2026-01-01 through 2026-12-31, continuous. That satisfies continuous enrolment full measurement year with no gaps. (Continuous, no more than one gap up to 45 days, here 0 gaps). OK.
- Event: at least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. Encounter on 2026-03-04: Office visit, diagnosis I10. That's an outpatient encounter (office visit) with I10 between Jan 1 and Jun 30. So event established. Qualifying hypertension encounter date = 2026-03-04.
- No exclusions? E1 ESRD/dialysis: no dialysis, no N18.6 mentioned. Record says "No hospice, no pregnancy, no dialysis." It doesn't explicitly mention N18.6 but says no dialysis, and presumably no ESRD. Also no ESRD diagnosis in encounters. So E1 not met. E2 pregnancy: none. E3 hospice/palliative: none. E4 died: member alive at year end. So no exclusions. (We assume not excluded).
- Numerator: most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31. Must be outpatient, not ED or inpatient. Both components below 140 systolic AND below 90 diastolic. Both must be below threshold.
Readings:
  2026-03-04: Office visit, BP 150/94. This is on the encounter date. But is it "taken on or after the date of the qualifying hypertension encounter"? Yes, same day counts as on or after? "on or after" means date >= encounter date. The reading was taken at the encounter? It says Office visit, diagnosis I10. BP 150/94. Same date as encounter. So it counts as a reading on/after. But it is not below thresholds (150 >=140, 94 >=90). However we need most recent outpatient BP reading on or after encounter date and on or before 2026-12-31. The most recent is 2026-10-14 Office visit, diagnosis I10, BP 134/92. That's an outpatient office visit, after 2026-03-04, before end of year. Check components: systolic 134 (<140) -> good. Diastolic 92. Is diastolic below 90? 92 is not below 90. Requirement: below 140 systolic AND below 90 diastolic. Both components must be below the threshold. Diastolic 92 is NOT below 90. Therefore the most recent reading does not meet numerator criteria. Since the most recent reading is the one used, and it fails, the member is non_compliant (in denominator, not excluded, does not meet numerator). Wait: The spec says "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic." If the most recent reading is 134/92, it is not below 90 diastolic, so numerator not met. If no qualifying reading exists, member is in denominator and not in numerator. But here there is a qualifying reading (outpatient, in date range) but it doesn't meet the BP thresholds, so numerator not met. Thus status = non_compliant.
- Reason: must be one sentence, under 30 words, naming the specific criterion or date that decided it. Need to state that most recent outpatient BP on 2026-10-14 was 134/92, diastolic not below 90, so not controlled. Or "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90." Need to be precise. Let's check: The "specific criterion or date that decided it". The deciding criterion: numerator requires both systolic <140 and diastolic <90; the 2026-10-14 reading had diastolic 92, so not met. Or the date of most recent reading 2026-10-14. Let's draft reason: "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." That's 21 words? Let's count: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92(8); diastolic(9) 92(10) is(11) not(12) below(13) 90(14), so(15) numerator(16) not(17) met(18). Under 30 words. Good.
But must reason be one sentence? Yes, one sentence, under 30 words. The above is one sentence (with a semicolon, still one sentence). Could also say: "The most recent outpatient BP reading on 2026-10-14 was 134/92, and diastolic 92 is not below 90." That's a sentence. Let's ensure it names specific criterion or date. It names date and the diastolic threshold criterion.

Check exclusions: none. Not excluded. Denominator: age 63, event 2026-03-04, continuous enrolment. So in denominator. Not excluded. Numerator not met (BP not controlled). So non_compliant.

Wait: Is there any nuance about the 2026-10-14 office visit having diagnosis I10. That's fine, it's another outpatient encounter. The BP reading is from that encounter. It is the most recent outpatient reading. It is not in ED or inpatient. Good.

One more nuance: The encounter on 2026-03-04 had BP 150/94. The most recent reading is 2026-10-14: 134/92. So the most recent is 2026-10-14. Systolic is 134 (<140) but diastolic is 92 (not <90). So fails.

Could there be an argument that the member is compliant because systolic and diastolic must both be below, but maybe 134/92 is not below 90 diastolic, so no.

Check age: DOB 1963-01-17. As of 2026-12-31, age is 63. (2026-1963=63). Since 18-85 inclusive? "Age: 18 through 85 years as of 2026-12-31." 63 is within. Good.

Enrolment: continuous full year, no gap. Good.

Required JSON keys:
"status": "non_compliant"
"reason": "..."

Wait, the task says: "Items drawn from measure QM-FUM require two further keys: met_7_day, met_30_day. For a member who is excluded or not_eligible under QM-FUM, report both as false." But this measure is QM-CBP, not QM-FUM. So we do NOT include met_7_day or met_30_day. The instruction: "Required JSON keys: status, reason". Then it says "Items drawn from measure QM-FUM require two further keys... For a member who is excluded or not_eligible under QM-FUM, report both as false." Since this is QM-CBP, we only output status and reason. Do not add met_7_day/met_30_day. The general instruction: "Do not add keys that were not asked for." So only status and reason.

Let's double-check if any exclusion could apply. Record: "No hospice, no pregnancy, no dialysis. Member alive at year end." It does not explicitly say no ESRD (N18.6), but says no dialysis. E1 is ESRD (N18.6) OR dependence on renal dialysis (Z99.2) any time on or before 2026-12-31. The record says no dialysis, but does it say no N18.6? It says "No hospice, no pregnancy, no dialysis." It doesn't mention ESRD, but typically they'd say no ESRD if they wanted to exclude. The instruction says "Where the supplied material does not settle the question, say so through the answer format rather than assuming a resolution." However, for exclusions, the record says "No hospice, no pregnancy, no dialysis." Usually in these synthetic tasks, "no dialysis" and not listing N18.6 means not met. Also the encounters list only I10. No N18.6. Since we are to answer from material, there is no ESRD or Z99.2 code in the record. The record states "No ... dialysis." Since Z99.2 is dependence on renal dialysis, that's explicitly not present. N18.6 is ESRD, not mentioned. Usually if they don't mention it, it's not present. We assume no exclusions.

But wait: The member had an office visit on 2026-10-14 with diagnosis I10. That's after the required event window (Jan 1 - Jun 30). The event must be on or between 2026-01-01 and 2026-06-30. The 2026-03-04 encounter establishes the event. The 2026-10-14 encounter is just another outpatient encounter with BP. That's fine; numerator looks at most recent outpatient BP reading on or after 2026-03-04. The 2026-10-14 reading qualifies as a reading. It doesn't need to be an encounter with I10? It is an office visit with diagnosis I10, but even if it were just a BP reading, it's an outpatient encounter. The spec says "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31". It doesn't require the reading to be at an encounter with hypertension diagnosis, just an outpatient BP reading. Here it is an office visit (outpatient) with BP. Good.

Let's construct reason string exactly. "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." Check word count: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92(8); diastolic(9) 92(10) is(11) not(12) below(13) 90(14), so(15) numerator(16) not(17) met(18). The date "2026-10-14" might be counted as one word. Under 30. Good.

Alternative: "The most recent outpatient BP reading on 2026-10-14 was 134/92, and diastolic 92 is not below 90." That's 21 words? The(1) most(2) recent(3) outpatient(4) BP(5) reading(6) on(7) 2026-10-14(8) was(9) 134/92(10), and(11) diastolic(12) 92(13) is(14) not(15) below(16) 90(17). 17 words. Very safe. It names date and criterion. I'll use: "The most recent outpatient BP reading on 2026-10-14 was 134/92, and diastolic 92 is not below 90." This is one sentence, under 30 words. It doesn't explicitly say "numerator not met", but the status says non_compliant and reason names criterion. The requirement: "naming the specific criterion or date that decided it". This names both date and criterion (diastolic below 90). It implies decision. Maybe better to tie to numerator: "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." That explicitly says numerator not met. It's still one sentence? It's a compound sentence with semicolon, then "so numerator not met." Actually it's: [Independent clause]; [independent clause], so [independent clause]. Still one sentence. Fine.

Let's ensure JSON format:
```json
{
  "status": "non_compliant",
  "reason": "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met."
}
```
Check if "BP" is okay. Yes.

Wait, is there any chance the 2026-10-14 visit is after the event window, and the qualifying hypertension encounter is 2026-03-04. The most recent reading is 2026-10-14. The BP is 134/92. Diastolic 92 is not below 90. So not compliant. Correct.

Let's double-check the denominator event requirement: "at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30." The 2026-03-04 office visit has diagnosis I10. Yes. "An encounter after 2026-06-30 does not establish the event." So the 2026-10-14 encounter doesn't establish event, but event already established. Good.

Continuous enrolment: "enrolled for the full measurement year with no more than one gap of up to 45 days." The member is enrolled 2026-01-01 through 2026-12-31, continuous. So OK.

Age: 18 through 85 as of 2026-12-31. DOB 1963-01-17. On 2026-12-31, age 63. OK.

Exclusions: E1 ESRD (N18.6) or Z99.2. Record says no dialysis (Z99.2 is renal dialysis). It doesn't say no N18.6. But no such diagnosis listed. In these tasks, if not listed or stated, it's not present. So no exclusion.

Thus status non_compliant.

One more check: The numerator says "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic." The reading on 2026-03-04 was 150/94 (also not below). The most recent is 2026-10-14. Even though systolic improved to 134, diastolic is 92. So fails. If the reading was, say, 134/88, it would be compliant. It's not.

Everything consistent.

Now produce final answer with exactly one fenced JSON code block and nothing else.
Keys: status, reason. No met_7_day/met_30_day because measure is QM-CBP, not QM-FUM.

Let's prepare final.

We need answer JSON with status, reason. Measure QM-CBP (not QM-FUM, so no met_7_day/met_30_day).
Let's parse member record.
DOB 1963-01-17. Age as of 2026-12-31: 2026 - 1963 = 63. On 2026-12-31, birthday Jan 17 already passed (1963-01-17 to 2026-01-17 turns 63). So age 63 as of 2026-12-31. Within 18-85. Good.
Event: at least one outpatient encounter with hypertension diagnosis I10 on or between 2026-01-01 and 2026-06-30. Encounter 2026-03-04 Office visit, diagnosis I10. Yes outpatient, I10, within window. Qualifying encounter date = 2026-03-04.
Continuous enrolment: enrolled 2026-01-01 through 2026-12-31 continuous. Yes full year with no gap. Eligible population yes.
Exclusions: E1 ESRD/dialysis none. E2 pregnancy none. E3 hospice none. E4 died? Member alive at year end. So no exclusions.
Numerator: most recent outpatient BP reading taken on or after date of qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic. Both components must be below threshold. A reading in ED or inpatient admission does not count and is skipped when identifying most recent reading. Encounters: 2026-03-04 office visit BP 150/94 (this is on qualifying encounter date; qualifies as after/on? The reading taken on or after date of encounter, yes on 2026-03-04. But we need most recent outpatient reading. There is 2026-10-14 office visit diagnosis I10, BP 134/92. Office visit is outpatient, not ED/inpatient. Most recent reading = 2026-10-14 BP 134/92. Systolic 134 < 140, diastolic 92. Diastolic must be below 90. 92 is NOT below 90. Therefore not meeting numerator criteria because diastolic 92 >= 90. So member is in denominator, not excluded, does not meet numerator -> non_compliant.
Need reason one sentence under 30 words naming specific criterion or date that decided it. Example: "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." Count words: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92(8); diastolic(9) 92(10) is(11) not(12) below(13) 90(14), so(15) numerator(16) not(17) met(18). Under 30. Good. It names date and criterion (diastolic below 90 threshold). Could mention eligible: age 63, encounter 2026-03-04. But reason should name specific criterion or date that decided it. Since status is non_compliant due to BP diastolic. Let's ensure no nuance: "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31". The qualifying encounter date is 2026-03-04. The 2026-03-04 reading occurs on the same day; it's considered "on or after" yes. Most recent is 2026-10-14. It's outpatient office visit, so counts. BP 134/92. Systolic below 140? 134 yes. Diastolic below 90? 92 no, so fails both-components rule. So non_compliant.
Check if any exclusion? Member alive, no hospice, no pregnancy, no dialysis. No E1-E4.
Check enrolment: continuous full year. Good.
Check event: outpatient encounter with I10 between Jan 1 and Jun 30. 2026-03-04 yes. The 2026-10-14 office visit with I10 is after Jun 30, but it's not needed for event; but could it be considered? It is an outpatient encounter with I10, but after Jun 30 does not establish event. However we already have qualifying event. No issue.
Check numerator reading: "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter". The date of qualifying encounter is 2026-03-04. The most recent reading is 2026-10-14. Good.
Need output exactly one fenced JSON code block with keys: "status", "reason". No extra keys. For QM-CBP no met_7_day etc. Required keys: status, reason. Since task family says Items drawn from QM-FUM require two further keys; this is QM-CBP, so only status and reason. Do not add keys.
Let's craft JSON:
{
  "status": "non_compliant",
  "reason": "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met."
}
Check reason under 30 words: Let's count strictly. "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." Words separated by spaces: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92(8); diastolic(9) 92(10) is(11) not(12) below(13) 90(14), so(15) numerator(16) not(17) met(18). The date token maybe one word; punctuation attached doesn't add words. Good.
It names specific criterion (diastolic below 90) and date (2026-10-14). Good.
Need ensure status string exactly one of: compliant, non_compliant, excluded, not_eligible. We have "non_compliant".
Let's verify no other possible status: Could member be excluded? No. Not_eligible? Age? 63 within 18-85. Enrolment continuous. Event yes. So denominator. Numerator not met due to diastolic 92. So non_compliant.
Double-check age: DOB 1963-01-17. As of 2026-12-31, age = 63. Indeed 2026-1963 = 63. Since birthday is Jan 17, by Dec 31 he is 63. Within 18-85. Good.
Continuous enrolment: 2026-01-01 through 2026-12-31, continuous. No gaps. Good.
One nuance: The numerator says "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31". The 2026-03-04 encounter had BP 150/94, but the most recent is 2026-10-14. It is outpatient. It is on or after 2026-03-04, and before end of year. Yes.
Does the 2026-10-14 encounter itself have diagnosis I10 and is after the event window, but it's still an outpatient encounter. It is used as a BP reading. The measure says "most recent outpatient blood pressure reading...". The reading doesn't need to be at an encounter with hypertension diagnosis? The spec says "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter". It doesn't require the reading's encounter to have I10. Here it does anyway. So fine.
BP thresholds: "below 140 systolic AND below 90 diastolic." 134 < 140 true. 92 < 90 false. So fails.
Reason sentence: Could also say "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90." That's even shorter. Need mention numerator not met? It says naming specific criterion or date that decided it. Could say "Diastolic 92 on the 2026-10-14 outpatient BP is not below 90, so the numerator is not met." That is clear. Count: Diastolic(1) 92(2) on(3) the(4) 2026-10-14(5) outpatient(6) BP(7) is(8) not(9) below(10) 90(11), so(12) the(13) numerator(14) is(15) not(16) met(17). Under 30. Good. Let's pick one. The first version: "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." Good.
Check JSON formatting: Need fenced code block with json. No other text. Ensure boolean not needed. Use null? no.
Let's produce final.

We need answer JSON with status, reason for QM-CBP. Need evaluate member against measure spec. Let's parse.

Measure QM-CBP, measurement year 2026-01-01 through 2026-12-31.

Member 40115. DOB 1963-01-17. As of 2026-12-31, age? Need calculate: on 2026-12-31, birth date 1963-01-17. Age = 2026-12-31 minus 1963-01-17 = 63 years (since birthday Jan 17 2026 passed; turned 63 on 2026-01-17). 63 within 18-85 inclusive. OK.

Continuous enrolment: 2026-01-01 through 2026-12-31, continuous. Full measurement year no gap. OK.

Event: at least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. Encounters: 2026-03-04 Office visit diagnosis I10 BP 150/94. That qualifies. Also 2026-10-14 is after 2026-06-30, doesn't establish event, but we have March one. So denominator eligible (unless exclusions).

Exclusions:
E1 ESRD N18.6 or dialysis Z99.2 any time on or before 2026-12-31. No dialysis, no ESRD indicated. Record says "No hospice, no pregnancy, no dialysis." It doesn't explicitly mention ESRD? It says no dialysis; ESRD N18.6? "No hospice, no pregnancy, no dialysis. Member alive at year end." It doesn't explicitly say no ESRD, but we infer from no dialysis? The exclusion E1 is ESRD or dependence on renal dialysis. We have no diagnosis codes besides I10 in encounters. Only record given. We must answer from material in prompt. No N18.6 mentioned. So probably no E1. Need not assume. If not mentioned, not present. Since given record lacks any ESRD/dialysis. It says no dialysis. No N18.6. So E1 not met.
E2 Pregnancy any O00-O9A during measurement year. No pregnancy. None.
E3 hospice/palliative during year. No hospice.
E4 died during year. Member alive at year end. Not met.
So not excluded.

Numerator: most recent outpatient BP reading taken on or after date of qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic. Both components must be below threshold. A reading taken in ED or inpatient does not count and is skipped when identifying most recent reading. If no qualifying reading exists, denominator not numerator.

Qualifying encounter date: 2026-03-04. Encounters/results: 2026-03-04 office visit BP 150/94; 2026-10-14 office visit I10 BP 134/92. Both are office visits (outpatient). We need most recent outpatient BP reading on or after 2026-03-04 and on or before 2026-12-31. The most recent is 2026-10-14 BP 134/92 (office visit, outpatient). It is after encounter date (March 4), within year. Not ED/inpatient. So qualifies as the most recent reading. Check thresholds: systolic 134 < 140? Yes, 134 below 140. Diastolic 92 < 90? No, 92 is not below 90. Both must be below; diastolic 92 is not below 90 (it's above). Therefore member does not meet numerator. So status = non_compliant. Because in denominator, not excluded, does not meet numerator (most recent BP 134/92, diastolic not <90).

Need reason string: one sentence, under 30 words, naming specific criterion or date that decided it. Should mention most recent outpatient BP on 2026-10-14 was 134/92, diastolic not below 90. Or "Most recent outpatient BP (2026-10-14) was 134/92; diastolic 92 is not below 90, so numerator not met." Count words: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92;(8) diastolic(9) 92(10) not(11) below(12) 90,(13) so(14) numerator(15) not(16) met(17). Under 30. Good. Need include status non_compliant. Reason under 30 words. Ensure JSON only.

Check keys: For QM-CBP no met_7_day/met_30_day because only QM-FUM requires them. The task says Items drawn from measure QM-FUM require two further keys. So for QM-CBP, only status and reason. Do not add keys. Good.

Need output exactly one fenced JSON code block and nothing else. No preamble/commentary. JSON object.

Let's ensure rounding? No money. Dates ISO not needed.

Potential nuance: "Event: at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30. An encounter after 2026-06-30 does not establish the event." We have 2026-03-04. Good. The 2026-10-14 encounter also has diagnosis I10 but after June 30; it doesn't establish the event, but it's still an outpatient encounter with BP. Does it count for numerator? Numerator says most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31. The 2026-10-14 is an outpatient encounter (office visit) with BP; it doesn't matter that it's after the event window? It is on or after the date of the qualifying encounter (March 4) and on or before Dec 31, outpatient, not ED/inpatient. It is a BP reading taken in office visit. It counts. So most recent is 2026-10-14. Good.

What about the 2026-03-04 BP 150/94: also outpatient, after encounter date same day. But most recent is Oct 14. So skip.

Check age: Must be 18 through 85 as of 2026-12-31. DOB 1963-01-17. On 2026-12-31, age = 63. Yes.

Check continuous enrolment: Enrolled full year continuous. No gaps. OK.

Exclusion evaluation before numerator. None. Not excluded.

Thus status non_compliant.

Wait: The reason field must name the specific criterion or date that decided it. The criterion is numerator: most recent outpatient BP reading must be <140/<90. The date 2026-10-14 reading had diastolic 92. The deciding criterion: diastolic not below 90. Let's write: "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." That's specific. Word count: Most1 recent2 outpatient3 BP4 on5 2026-10-146 was7 134/928 diastolic9 9210 is11 not12 below13 9014 so15 numerator16 not17 met18. Good.

Need ensure no period? It's a sentence. Fine.

Let's produce JSON:

```json
{
  "status": "non_compliant",
  "reason": "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met."
}
```

Check JSON validity: string with semicolon and slashes fine. No trailing comma. Good.

Wait, any need to mention "in denominator"? No. Reason under 30 words. Let's recount with "Most recent outpatient BP on 2026-10-14 was 134/92; diastolic 92 is not below 90, so numerator not met." Words:
1 Most
2 recent
3 outpatient
4 BP

6 2026-10-14
7 was
8 134/92
9 diastolic
10 92
11 is
12 not
13 below
14 90
15 so
16 numerator
17 not
18 met
Yes. Under 30.

Alternative: Could status be compliant if reading 134/92? No, both components must be below threshold. Diastolic 92 is not below 90. It's above. So not compliant.

Double-check thresholds: "below 140 systolic AND below 90 diastolic." 134 < 140 yes. 92 < 90? No. So fails.

One nuance: "A reading taken in an emergency department or on an inpatient admission does not count and is skipped when identifying the most recent reading." Office visits are outpatient. Good.

Could the 2026-10-14 encounter diagnosis I10 after 2026-06-30 not establish event but does it count as a qualifying hypertension encounter date? The numerator says "on or after the date of the qualifying hypertension encounter". Qualifying hypertension encounter is the March 4 one. It doesn't require the later encounter to be a qualifying encounter. The later reading just needs to be on or after date of qualifying encounter. Oct 14 is after March 4. So yes.

Could there be an issue with "most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31" and the Oct 14 reading is tied to an office visit diagnosis I10, but the event was established by March encounter. Yes.

Thus final. Ensure exactly one fenced code block. No other text. Use ```json ... ```. Done.

 We need to apply QM-CBP measure to member record.

First, check denominator eligibility:

Age: 18 through 85 years as of 2026-12-31. DOB 1963-01-17. As of 2026-12-31, age is 2026 - 1963 = 63 (since birthday in Jan). 63 is between 18 and 85 inclusive. So age eligible.

Event: at least one outpatient encounter with hypertension diagnosis I10 on or between 2026-01-01 and 2026-06-30. Member has 2026-03-04 office visit dx I10. This is within the window. So event met.

Continuous enrollment: enrolled full measurement year 2026-01-01 through 2026-12-31, continuous. No gaps >45 days. Record says continuous. So enrollment met.

Thus member is in denominator.

Now exclusions:

E1: End stage renal disease or dialysis. Record says no dialysis. No mention of N18.6. So not excluded.

E2: Pregnancy. Male, so no pregnancy. Not excluded.

E3: Hospice or palliative care. Record says no hospice. So not excluded.

E4: Died during measurement year. Alive at year end. So not excluded.

Member is not excluded.

Now numerator:

The most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31.

The qualifying hypertension encounter is the one that establishes event: 2026-03-04. The numerator looks at the most recent outpatient BP reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31. The reading must be below 140 systolic AND below 90 diastolic. Both components must be below threshold.

Encounter readings:

2026-03-04 office visit BP 150/94. Taken on the date of qualifying encounter. Systolic 150 >=140, diastolic 94 >=90. Not compliant.

2026-10-14 office visit BP 134/92. Taken after qualifying encounter. Systolic 134 <140, diastolic 92 >=90. Since diastolic not below 90, this reading does NOT meet numerator. The numerator requires BOTH components below threshold.

If no qualifying reading exists, member is in denominator and not in numerator. But there are readings; the most recent reading is 2026-10-14 with BP 134/92. It does not meet the threshold because diastolic is 92 (not below 90). So member fails numerator.

Therefore status: non_compliant.

Reason: one sentence under 30 words naming specific criterion or date that decided it. Something like: "Most recent outpatient BP on 2026-10-14 was 134/92, diastolic not below 90." Let's count words. "Most recent outpatient BP on 2026-10-14 was 134/92, diastolic not below 90." That's 11 words. Good. Or "Most recent outpatient blood pressure reading on 2026-10-14 was 134/92, diastolic not below 90." That's fine.

Need JSON with keys status and reason. No other keys for QM-CBP. Wait, QM-CBP doesn't require met_7_day or met_30_day; only QM-FUM does. So just status and reason.

Wait, check if there are any subtleties: The qualifying hypertension encounter is on 2026-03-04. The numerator says "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31". Does the blood pressure reading have to be from an outpatient encounter with a hypertension diagnosis? Let's read numerator: "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic." It doesn't say it must be taken during a hypertension encounter, just an outpatient reading. The record says office visits with dx I10. Both are outpatient. So fine.

Could there be a question about "most recent outpatient blood pressure reading" meaning if there are multiple, we take the most recent one. The most recent is 2026-10-14. That reading fails. So non-compliant.

Wait, is there any nuance about the first reading being on the qualifying encounter? It is taken on the same date, but the most recent reading is the later one. So we ignore the earlier one.

Thus answer: status non_compliant, reason as above.

Make sure it's exactly one fenced JSON block.

Should I include any extra keys? No.

Check reason length: under 30 words. "Most recent outpatient blood pressure reading on 2026-10-14 was 134/92, diastolic not below 90." Let's count: Most(1) recent(2) outpatient(3) blood(4) pressure(5) reading(6) on(7) 2026-10-14(8) was(9) 134/92,(10) diastolic(11) not(12) below(13) 90(14). Good.

Make sure no trailing punctuation issue. Fine.

So final JSON:

```json
{
  "status": "non_compliant",
  "reason": "Most recent outpatient blood pressure reading on 2026-10-14 was 134/92, diastolic not below 90."
}
```

Double-check: Is there any chance the member is excluded? E1: no mention of ESRD. E2: male. E3: no hospice. E4: alive. None apply.

Denominator: age 63, event 2026-03-04 dx I10, continuous enrollment. Good.

Therefore non_compliant.

One more thought: The event window is 2026-01-01 through 2026-06-30. The encounter on 2026-03-04 qualifies. The second encounter on 2026-10-14 is after the event window but still provides a BP reading that can be used for numerator because numerator uses reading on or after the date of the qualifying encounter. Yes.

Now, is the second encounter considered "outpatient"? Office visit, yes.

Everything seems straightforward.

Wait, could there be any nuance about "the most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter"? The qualifying hypertension encounter date is 2026-03-04. The BP on that date is 150/94. The BP on 2026-10-14 is 134/92. Both are outpatient. The most recent is 2026-10-14. It fails because diastolic 92 >= 90. So non-compliant.

Thus answer is correct.

Just to be safe, let's verify that the JSON is exactly one fenced block and nothing else.

Yes.

Now output.

The user wants me to evaluate a member against the QM-CBP measure specification.

Let me break down the member record:
- Member 40115
- DOB: 1963-01-17
- Male
- Enrolment: 2026-01-01 through 2026-12-31, continuous
- Encounters:
  - 2026-03-04: Office visit, diagnosis I10. BP 150/94.
  - 2026-10-14: Office visit, diagnosis I10. BP 134/92.
- No hospice, no pregnancy, no dialysis. Member alive at year end.

Now apply the measure:

Denominator criteria:
1. Age: 18 through 85 years as of 2026-12-31.
   - DOB 1963-01-17. As of 2026-12-31, age is 2026-1963 = 63 years old. (Born in Jan, so yes, 63). This is within 18-85. ✓

2. Event: at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30.
   - 2026-03-04: Office visit, diagnosis I10. This is within the date range and is an outpatient encounter. ✓

3. Continuous enrolment: enrolled for the full measurement year with no more than one gap of up to 45 days.
   - Enrolment: 2026-01-01 through 2026-12-31, continuous. So no gaps. ✓

Member is in the denominator.

Exclusions:
- E1: End stage renal disease (N18.6) or dependence on renal dialysis (Z99.2) any time on or before 2026-12-31. → No. Record says no dialysis.
- E2: Pregnancy (any O00-O9A code) during the measurement year. → Male, no pregnancy.
- E3: Enrolled in hospice or receiving palliative care at any time during the measurement year. → No hospice.
- E4: Died during the measurement year. → Alive at year end.

No exclusions apply.

Numerator:
"The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic. Both components must be below the threshold. A reading taken in an emergency department or on an inpatient admission does not count and is skipped when identifying the most recent reading. If no qualifying reading exists, the member is in the denominator and not in the numerator."

Qualifying hypertension encounter: 2026-03-04 (I10). There could be others, but we need the most recent outpatient BP reading taken on or after the qualifying encounter date and on or before 2026-12-31.

Wait, the wording: "taken on or after the date of the qualifying hypertension encounter". Since there could be multiple qualifying encounters, I need to interpret this carefully.

Usually in HEDIS-style measures, the "qualifying encounter" refers to the encounter that establishes the event in the denominator. Here, the event is "at least one outpatient encounter with a hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30". So the qualifying encounter is the one that satisfies this. In this case, 2026-03-04 is the only one in the first half.

But what about the 2026-10-14 encounter? It has diagnosis I10 but is after 2026-06-30, so it does not establish the event, but the numerator says "taken on or after the date of the qualifying hypertension encounter". This could mean any reading on or after the specific date of the qualifying encounter (March 4). The October 14 reading is after March 4.

However, does the October 14 reading count as "outpatient"? Yes, it's an office visit. Is it taken on or after the qualifying hypertension encounter? Yes, Oct 14 is after March 4. Is it on or before 2026-12-31? Yes.

So the readings to consider are:
- 2026-03-04: BP 150/94. Systolic 150 (not < 140), diastolic 94 (not < 90).
- 2026-10-14: BP 134/92. Systolic 134 (< 140), diastolic 92 (not < 90).

The most recent qualifying reading is 2026-10-14: BP 134/92.
Systolic is 134 < 140. Diastolic is 92, which is NOT < 90.
Since both components must be below the threshold, the member does NOT meet the numerator.

Therefore: status is "non_compliant".
Reason: need one sentence under 30 words naming the specific criterion or date that decided it.
The decision is based on the most recent BP reading (2026-10-14) being 134/92, where diastolic is not below 90.
Or: "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90."
Wait, count words: "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90." Let's count: Most(1) recent(2) BP(3) on(4) 2026-10-14(5) was(6) 134/92;(7) diastolic(8) not(9) below(10) 90.(11) That's 11 words. Good.

Let me double check: is there any ambiguity about whether the October 14 encounter counts as a "qualifying hypertension encounter"? The numerator says "taken on or after the date of the qualifying hypertension encounter". If there are multiple qualifying encounters, it's the date of the encounter. But the October 14 encounter is not a qualifying encounter for the denominator because it's after June 30. However, the BP reading itself is taken during an outpatient visit on or after the date of the qualifying encounter (March 4). The numerator criteria don't say the reading must be taken at a qualifying encounter, just "on or after the date of the qualifying hypertension encounter and on or before 2026-12-31". So any outpatient BP reading after the qualifying encounter date counts.

Thus the most recent is Oct 14. 134/92. Diastolic >= 90. Non-compliant.

Keys required:
"status": "non_compliant"
"reason": "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90."

Wait, the measure specification says: "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic."

Yes.

Final check on exclusions vs numerator order: exclusions first. None apply. Then numerator. Not met.

Is there any chance the March 4 reading is the only one considered because the October 14 encounter is not a "qualifying hypertension encounter"? The phrase "qualifying hypertension encounter" is defined in the denominator as an outpatient encounter with I10 between Jan 1 and June 30. So the qualifying encounter is March 4. The numerator refers to "the date of the qualifying hypertension encounter" (singular). So readings on or after March 4. October 14 is on or after March 4. So it counts.

Another interpretation: Maybe "qualifying hypertension encounter" means any encounter with I10, but the denominator limits the event period. The numerator doesn't restrict the reading to be at a qualifying encounter, just the date. So yes, Oct 14 counts.

Therefore non_compliant.

Wait, let me re-read carefully: "The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter and on or before 2026-12-31..."

The "qualifying hypertension encounter" is the encounter that made them enter the denominator. That's the March 4 one. So any outpatient BP reading from March 4 onward. The October 14 reading is outpatient and on or after March 4. It is the most recent. 134/92. Diastolic 92 is not below 90. So non-compliant.

The JSON should be:

```json
{
  "status": "non_compliant",
  "reason": "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90."
}
```

Word count check: Most(1) recent(2) BP(3) on(4) 2026-10-14(5) was(6) 134/92;(7) diastolic(8) not(9) below(10) 90.(11) 11 words. Under 30. Good.

One more check: is "2026-10-14" one word or two? Usually hyphenated dates or numbers are one token/word. But to be safe, I can write: "Most recent blood pressure reading on 2026-10-14 was 134 over 92, failing diastolic threshold." Let's count: Most(1) recent(2) blood(3) pressure(4) reading(5) on(6) 2026-10-14(7) was(8) 134(9) over(10) 92,(11) failing(12) diastolic(13) threshold.(14) That's fine.

But I think the shorter one is better. I'll keep it concise.

Actually, let me make sure the status values are exactly as required:
"compliant", "non_compliant", "excluded", "not_eligible". Yes.

Reason should name the specific criterion or date that decided it. The date 2026-10-14 and the value 134/92 are the deciding factors. Or the diastolic not being below 90.

I'll go with:
"Most recent BP 134/92 on 2026-10-14; diastolic threshold not met."
Count: Most(1) recent(2) BP(3) 134/92(4) on(5) 2026-10-14;(6) diastolic(7) threshold(8) not(9) met.(10) Good.

Wait, is there any requirement to mention the criterion? "naming the specific criterion or date that decided it". The criterion is the numerator threshold for diastolic. I can mention that.

"Diastolic 92 on 2026-10-14 exceeds 90 threshold." Count: Diastolic(1) 92(2) on(3) 2026-10-14(4) exceeds(5) 90(6) threshold.(7) Good.

But it's the most recent reading. Should I mention that? The measure looks for the most recent. But the reason can just say the diastolic was too high on that date. I think that's sufficient.

Let's do: "Most recent outpatient BP on 2026-10-14 was 134/92, diastolic not below 90."
Count: Most(1) recent(2) outpatient(3) BP(4) on(5) 2026-10-14(6) was(7) 134/92,(8) diastolic(9) not(10) below(11) 90.(12) Fine.

Actually, to be super precise about the criterion: The numerator requires both <140 and <90. The diastolic failed.

I think any of these are fine. I'll use: "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90."

Double check: no hospice, no pregnancy, no dialysis. Alive. Continuous enrollment. Age 63. Event on 2026-03-04. All good.

One final thought: Could the BP reading on 2026-03-04 be the one used because the 2026-10-14 encounter is after June 30 and thus the diagnosis on that date doesn't count for something? The numerator says "outpatient blood pressure reading... taken on or after the date of the qualifying hypertension encounter". It does not say the reading must be associated with a qualifying encounter. It just sets the lower date bound. So Oct 14 counts.

Also, the spec says "A reading taken in an emergency department or on an inpatient admission does not count". This is an office visit, so it counts.

Yes, non_compliant is correct.

Output must be exactly one fenced JSON code block and nothing else.

```json
{
  "status": "non_compliant",
  "reason": "Most recent BP on 2026-10-14 was 134/92; diastolic not below 90."
}
```

 We need to evaluate member record against QM-CBP measure.

Denominator:
- Age 18 through 85 as of 2026-12-31. DOB 1963-01-17. Age at 2026-12-31: 2026 - 1963 = 63 years old (exactly? from Jan 17 to Dec 31, 2026, yes turning 63 on Jan 17, 2026). So age 63, within 18-85.
- Event: at least one outpatient encounter with hypertension diagnosis I10 between 2026-01-01 and 2026-06-30. The member has an office visit on 2026-03-04 with diagnosis I10. That is within the date range, outpatient. So event satisfied.
- Continuous enrollment: enrolled full measurement year with no more than one gap up to 45 days. Enrollment 2026-01-01 through 2026-12-31 continuous. So yes.

Thus member is in denominator.

Now exclusions: E1 none, E2 none (male), E3 none, E4 none (alive). So not excluded.

Numerator: The most recent outpatient blood pressure reading taken on or after the date of the qualifying hypertension encounter (which is 2026-03-04) and on or before 2026-12-31 is below 140 systolic AND below 90 diastolic. Both components must be below threshold.

Readings:
- 2026-03-04 BP 150/94. Outpatient (office visit). On or after 2026-03-04.
- 2026-10-14 BP 134/92. Outpatient. On or after 2026-03-04.

Most recent is 2026-10-14: 134 systolic (below 140 yes) and 92 diastolic (below 90? No, 92 >= 90). So not below 90. Therefore numerator not met. Member is in denominator, not excluded, does not meet numerator: non_compliant.

Need status: "non_compliant".
reason: under 30 words, naming specific criterion or date that decided it. Could say "Most recent BP 134/92 on 2026-10-14; diastolic not below 90." Let's check word count: Most(1) recent(2) BP(3) 134/92(4) on(5) 2026-10-14;(6) diastolic(7) not(8) below(9) 90.(10) That's 10 words. Good.

Also there are no extra keys for QM-CBP (only QM-FUM requires met_7_day and met_30_day). So just status and reason.

Double-check: Are there any other readings? No. Are both readings outpatient? Office visits, yes outpatient. Emergency or inpatient? No.

Thus answer:

```json
{
  "status": "non_compliant",
  "reason": "Most recent BP 134/92 on 2026-10-14; diastolic not below 90."
}
```

Check length: under 30 words. Good.

Double-check member age: DOB 1963-01-17. As of 2026-12-31, age = 63. Fine.

Enrollment: continuous, no gaps. Fine.

No exclusions. Fine.

So final JSON.

1.  **Analyze the Request**
    *   Task: Evaluate member record against QM-CBP quality measure logic.
    *   Need to output JSON with "status" and "reason".
    *   Let's check the member's details against the criteria.

2.  **Check Inclusion Criteria (Denominator)**
    *   Age: DOB is 1963-01-17. At 2026-12-31, age = 63 years. (2026 - 1963 = 63). Within 18-85.
    *   Event: Has an outpatient visit with diagnosis I10 on 2026-03-04 (BP 150/94). This is between 2026-01-01 and 2026-06-30. Qualifying.
    *   Continuous enrolment: Enrolled 2026-01-01 through 2026-12-31, continuous. Qualifying.
    *   Therefore, the member is in the denominator.

3.  **Check Exclusions**
    *   E1: ESRD/dialysis (N18.6/Z99.2)? "No hospice, no pregnancy, no dialysis." Not present.
    *   E2: Pregnancy (O00-O9A)? Not present.
    *   E3: Hospice/palliative care? "No hospice, no pregnancy, no dialysis." Not present.
    *   E4: Died during year? "Member alive at year end." Not present.
    *   Exclusion Status: Not excluded.

4.  **Check Numerator**
    *   Most recent qualifying BP reading on/after 2026-03-04 and on/before 2026-12-31.
    *   Reading 1: 2026-03-04 BP 150/94.
    *   Reading 2: 2026-10-14 BP 134/92.
    *   ED/inpatient readings? No.
    *   Most recent qualifying reading is 2026-10-14: 134/92.
    *   Is 134 < 140 AND 92 < 90? No, 92 is not < 90.
    *   Therefore, the member does not meet the numerator.

5.  **Determine Status**
    *   In denominator: Yes.
    *   Excluded: No.
    *   Meets numerator: No.
    *   Status: "non_compliant"

6.  **Reason**
    *   One sentence, under 30 words. Name the specific criterion or date that decided it.
    *   Most recent BP was 2026-10-14 at 134/92, which is not below 140/90.
    *   "The most recent qualifying BP reading on 2026-10-14 was 134/92, which is not below 140/90."

7.  **Check required keys**
    *   QM-CBP doesn't seem to require the "met_7_day" and "met_30_day" keys; that was only for QM-FUM. So just "status" and "reason".

Let me work through this systematically using the QM-CBP specification.

**STEP 1: Check Eligibility (Denominator)**

Age requirement (as of 2026-12-31):
- DOB: 1963-01-17
- Age on 2026-12-31: 2026 - 1963 = 63 years old
- Requirement: 18 through 85 years
- ✓ MEETS AGE REQUIREMENT

Event requirement (hypertension encounter with I10 between 2026-01-01 and 2026-06-30):
- 2026-03-04: Office visit, diagnosis I10 ✓ (within the window)
- 2026-10-14: Office visit, diagnosis I10 (after 2026-06-30, doesn't count for establishing the event)
- ✓ MEETS EVENT REQUIREMENT

Continuous enrolment (enrolled for full measurement year with no more than one gap of up to 45 days):
- Enrolment: 2026-01-01 through 2026-12-31, continuous
- ✓ MEETS ENROLMENT REQUIREMENT

The member enters the denominator.

**STEP 2: Check Exclusions**

E1. End stage renal disease (N18.6) or dependence on renal dialysis (Z99.2) any time on or before 2026-12-31:
- Record states "No hospice, no pregnancy, no dialysis"
- No N18.6 or Z99.2 codes mentioned
- ✗ NOT EXCLUDED
E2-E4 also don't apply — record confirms no pregnancy, no hospice/palliative care, and the member was alive at year end.

Member is NOT excluded.

**STEP 3: Check Numerator**

I need the most recent outpatient BP reading on or after 2026-03-04 (the qualifying encounter) and on or before 2026-12-31, requiring systolic below 140 AND diastolic below 90. Readings from ED visits or inpatient stays don't count and get skipped.

- 2026-03-04: 150/94 — fails both
- 2026-10-14: 134/92 — systolic passes (134<140) but diastolic fails (92 is not <90)

The most recent qualifying reading is 2026-10-14: 134/92. Since diastolic 92 is not below 90, the numerator is NOT met even though systolic passes.

**DECISION:** Denominator met, no exclusions apply, but numerator fails due to the diastolic reading of 92.

Status: "non_compliant"

Reason: "Most recent BP reading (134/92) fails diastolic threshold of <90."

That's concise and under 30 words, so it works well. I'll go with this phrasing since it clearly states the specific reading and why it fails.

Let me work through this step-by-step using the QM-CBP measure specification.

**Step 1: Check if member is in the denominator (ELIGIBLE POPULATION)**

Age requirement: 18 through 85 years as of 2026-12-31
- DOB: 1963-01-17
- Age on 2026-12-31: 2026 - 1963 = 63 years old
- ✓ Meets age requirement

Event requirement: at least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30
- 2026-03-04: Office visit with I10 diagnosis
- This is within the window (2026-01-01 through 2026-06-30)
- ✓ Meets event requirement

Continuous enrolment: enrolled for the full measurement year with no more than one gap of up to 45 days
- Enrolment: 2026-01-01 through 2026-12-31, continuous
- ✓ Meets continuous enrolment requirement

The member IS in the denominator.

**Step 2: Check for required exclusions**

E1. End stage renal disease (N18.6) or dependence on renal dialysis (Z99.2) any time on or before 2026-12-31
- Record states: "No hospice, no pregnancy, no dialysis"
- ✗ Not excluded

E2. Pregnancy (any O00-O9A code) during the measurement year
- Record states: "No hospice, no pregnancy, no dialysis"
- ✗ Not excluded

E3. Enrolled in hospice or receiving palliative care at any time during the measurement year
- Record states: "No hospice, no pregnancy, no dialysis"
- ✗ Not excluded
E4. Died during the measurement year
- Record states: "Member alive at year end"
- ✗ Not excluded

The member is NOT excluded, so they remain in the denominator.

**Step 3: Check the numerator (BLOOD PRESSURE CONTROL)**

I need the most recent outpatient BP reading on or after the qualifying hypertension encounter (2026-03-04) and on or before 2026-12-31, checking if it's below 140/90.

- 2026-03-04: BP 150/94 — this is the qualifying visit itself, systolic 150 fails the threshold

- 2026-10-14: BP 134/92 — falls within the valid date range, systolic 134 passes but diastolic 92 fails (not below 90)

Since both components must be below threshold and the most recent reading has diastolic 92, this doesn't satisfy the numerator.

**Conclusion:** non_compliant — the member is in the denominator, not excluded, but the numerator is not met.

Reason: "Most recent BP reading (134/92) fails diastolic requirement of below 90." — concise, under 30 words.

92 exceeding 90 threshold — 13 words total, clean and clear.

Settling on: "Most recent BP reading 134/92 fails diastolic requirement below 90."

Let me work through this systematically according to the measure QM-CBP specification.

**Step 1: Determine eligibility for the denominator**

Age requirement: Born 1963-01-17, measured as of 2026-12-31.
- Age = 2026 - 1963 = 63 years old as of 2026-12-31. ✓ (within 18-85)

Event requirement: At least one outpatient encounter with hypertension diagnosis (I10) on or between 2026-01-01 and 2026-06-30.
- 2026-03-04: Office visit with I10 diagnosis ✓ (within the window)
- 2026-10-14: Office visit with I10 diagnosis, but this is AFTER 2026-06-30, so it doesn't count for establishing the event

The member has a qualifying encounter on 2026-03-04. ✓

Continuous enrollment: Enrolled for full measurement year (2026-01-01 through 2026-12-31) with no more than one gap of up to 45 days.
- Record states: "Enrolment: 2026-01-01 through 2026-12-31, continuous." ✓

The member enters the denominator.

**Step 2: Check for required exclusions**

E1. End stage renal disease (N18.6) or dependence on renal dialysis (Z99.2) on or before 2026-12-31.
- Record states: "No hospice, no pregnancy, no dialysis." ✓ Not excluded

E2. Pregnancy (any O00-O9A code) during the measurement year.
- Record states: "no pregnancy" ✓ Not excluded

E3. Enrolled in hospice or receiving palliative care at any time during the measurement year.
- Record states: "No hospice" ✓ Not excluded
E4. Died during the measurement year.
- Record states: "Member alive at year end." ✓ Not excluded

None of the exclusions apply, so the member stays in the denominator.

**Step 3: Assess numerator compliance**

Numerator needs the most recent outpatient BP reading, taken on/after 2026-03-04 and on/before 2026-12-31, showing systolic under 140 and diastolic under 90.

Looking at readings: 2026-03-04 shows 150/94, which is the encounter date itself and fails both thresholds.

2026-10-14 shows 134/92 - falls within the valid window, systolic 134 passes but diastolic 92 fails, so the reading as a whole doesn't qualify since both components must clear the threshold.

The most recent reading (134/92) fails on diastolic, so numerator compliance isn't met.

Status: non_compliant — member is in denominator, not excluded, but the numerator condition fails.

Reason should be concise: "Most recent BP reading (2026-10-14, 134/92)

134/92; diastolic exceeds 90 threshold. Settling on: most recent outpatient BP reading (2026-10-14, 134/92) fails the diastolic <90 requirement.
