Stool DNA test inside the three-year window

**My Thought Process for Evaluating QM-CRC Compliance**

Alright, the core task here is to determine if this particular member meets the criteria for the QM-CRC (Colorectal Cancer Screening) measure. I need to work through the eligibility and numerator requirements systematically.

First, I'll establish the measurement year – it's clearly defined as January 1, 2026, through December 31, 2026.

Next, the eligible population. The member must be between 46 and 75 years old as of December 31, 2026. Checking their Date of Birth (DOB) of January 8, 1974, I see they'll be 52 years old at the end of 2026. That hits the age requirement precisely. Then, there's the continuous enrollment stipulation: they need to be enrolled for the entirety of 2026. Their enrollment record shows January 1, 2026, to December 31, 2026, which is continuous. So, the member is definitely within the denominator.

Now, I need to consider any exclusions. The criteria are: no colorectal cancer, no total colectomy, no hospice care, and no frailty or advanced illness. Based on the information I have, none of these exclusions apply to this member. This confirms they remain in the denominator for measurement.

Moving on to the numerator. This is where I look for evidence of screening. The look-back window is crucial here. It extends back from December 31, 2026.

For the first numerator condition (N1), I'm looking for a FOBT (fecal occult blood test) or FIT (fecal immunochemical test) performed in 2026. A quick scan of their history for 2026 shows no such tests. So, N1 is not met.

However, the second numerator condition (N2) is met. This requires a stool DNA test performed during 2026 *or* the two years prior to 2026. This creates a three-year look-back window: 2024, 2025, and 2026. I found a record of a stool DNA test on September 17, 2024. Since 2024 falls within that three-year window (2024, 2025, 2026), this test satisfies the N2 requirement. The result of that test was negative, which is good, but the key for compliance is that the *test itself* occurred within the specified timeframe.

Therefore, the member is compliant.

My refined reason for compliance is that the member had a stool DNA test on September 17, 2024, which falls within the required three-year look-back window, thereby satisfying the numerator.

For the final output, I need to ensure I'm providing the correct JSON keys. The instructions clearly state that for QM-CRC, only "status" and "reason" are required. The specific keys QM-FUM doesn't apply here. So, the structure will be:

`"status": "compliant"`
`"reason": "The member had a stool DNA test on 2024-09-17, satisfying the numerator within the three-year look-back window."`

I've double-checked the wording of N2 and the dates – 2024 is indeed two years prior to 2026, making the September 17, 2024, test valid for the three-year window. Everything checks out. The member is compliant.

**My Thought Process for Evaluating Member 40203 Against QM-CRC Measure**

Alright, let's break down this evaluation for member 40203 against the QM-CRC measure for the 2026 measurement year. My primary goal here is to determine their compliance status and articulate the precise reason for it, ensuring I adhere to the specified output format.

First, I need to confirm the member's eligibility for the measure.
*   **Age Criteria:** The member was born in 1974, making them 52 years old by the end of 2026. The eligible age range is 46-75. This is met.
*   **Continuous Enrollment:** The member was continuously enrolled from January 1, 2026, through December 31, 2026. This also meets the criteria.

With eligibility established, I move on to the denominator. Based on the age and enrollment criteria, I can confidently state that the member meets the **denominator criteria**.

Now, the critical part: the **numerator criteria**. This is where I need to check if the member has undergone any of the specified screening methods within the relevant timeframes. The numerator includes five potential pathways (N1-N5):
*   N1: FOBT or FIT in 2026.
*   N2: Stool DNA test in 2026 or the two years prior (a 3-year window: 2024, 2025, 2026).
*   N3: Flexible sigmoidoscopy (5-year window).
*   N4: CT colonography (5-year window).
*   N5: Colonoscopy (10-year window).

Looking at the member's record, I see a significant piece of information: a **stool DNA test performed on 2024-09-17**. This date falls squarely within the 3-year look-back window for the stool DNA test (N2), which covers 2024, 2025, and 2026. Therefore, the member **meets the numerator criteria via pathway N2**.

Next, I need to consider any **exclusions**. The common exclusions are:
*   Having a diagnosis of colorectal cancer.
*   Undergoing a colectomy.
*   Being on hospice.
*   Age-related exclusions (like being outside the 46-75 range, which we've already confirmed isn't the case here).

From the provided information, there are no stated exclusions for this member. They are not noted as having cancer, having undergone a colectomy, or being on hospice. Their age is also within the appropriate range.

So, to summarize my findings:
*   The member meets the denominator criteria.
*   The member is not excluded.
*   The member meets the numerator criteria through the stool DNA test.

This leads me to the final **status**: **"compliant"**.

Now, I need to articulate the **reason** for compliance. It's important to be concise and directly reference the criterion that was met. The stool DNA test in 2024 is the key. I've considered a few phrasing options to ensure clarity and brevity. I need to avoid mentioning extra keys that might be relevant to QM-FUM but not QM-CRC. The prompt specifically states that QM-CRC only requires "status" and "reason" keys.

After reviewing the N2 definition again ("Stool DNA test during 2026 or the two years prior (three-year window)"), and confirming that 2024 is indeed "the two years prior" to 2026, the date 2024-09-17 is perfectly within this window.

Therefore, the most accurate and concise reason is: "Member meets the numerator with a stool DNA test performed in 2024, within the three-year window." This is 16 words, well within any implied length constraints for a reason.

So, the final output will be:
*   **status**: "compliant"
*   **reason**: "Member meets the numerator with a stool DNA test performed in 2024, within the three-year window."

**My Thought Process for Assessing QM-CRC Compliance**

Okay, let's break down this QM-CRC compliance check step-by-step. My primary goal here is to determine if the member meets the criteria for compliance with the Quality Measure for Colorectal Cancer screening.

First, I need to establish if the member is even in the running – are they in the denominator? The measurement year is the full calendar year 2026 (January 1st to December 31st). The member was born in January 1974, which makes them 52 years old as of December 31st, 2026. The eligible population for this measure is individuals aged 46 through 75 at the end of the measurement year. Since 52 falls squarely within this range, they are eligible by age.

Next, I check for continuous enrollment. The measure requires full measurement year enrollment with at most one gap of up to 45 days. This member was enrolled from January 1st, 2026, through December 31st, 2026. That's perfect continuous enrollment, so they are eligible in this regard as well. Therefore, this member is definitely in the denominator.

Now, I need to consider any exclusions. I'll go through them one by one:
*   **E1: Colorectal cancer diagnosis:** The information indicates "no."
*   **E2: Total colectomy:** Again, the information says "no."
*   **E3: Hospice care:** Also marked as "no."
*   **E4: Age 66 or older, with frailty and advanced illness:** The member is only 52, so this exclusion doesn't apply.

Since none of the exclusion criteria are met, the member remains eligible for further evaluation for the numerator.

Now for the numerator – did they actually get screened? The measure outlines several numerator options:
*   **N1: FOBT or FIT during 2026:** The data shows "No" for this.
*   **N2: Stool DNA test during 2026 or the two years prior.** This is a three-year look-back window, encompassing 2024, 2025, and 2026. I check the member's record and find they had a Stool DNA test on September 17th, 2024. This date falls within the 2024 portion of the look-back window, so this criterion is met.
*   **N3, N4, N5:** These are not applicable or not met based on the provided information.

Since the member meets the criteria for numerator option N2, they are compliant.

Finally, I need to format the output according to the requirements. The prompt specifies a JSON format with "status" and "reason" keys. I've confirmed that the "QM-FUM" specific keys are *not* required here, as this is the QM-CRC measure.

The status is clearly "compliant." For the reason, I need to be concise (under 30 words) and name the specific criterion met and the relevant date. The member met the numerator through a stool DNA test performed on September 17th, 2024, which falls within the allowed three-year look-back window (2024-2026). This gives me a clear and precise reason.

So, the final output looks like this:

```json
{
  "status": "compliant",
  "reason": "Member meets the numerator with a stool DNA test on 2024-09-17, which is within the three-year window."
}
```
I've double-checked the word count for the reason (18 words) and confirmed it's well under the limit and includes the necessary details. Everything seems correct.

**My Thought Process for Assessing Colorectal Cancer Screening Compliance**

My primary task here is to determine the compliance status for Measure QM-CRC (Colorectal Cancer Screening) for a specific member, Member 40203, for the measurement year 2026. I need to meticulously work through the eligibility criteria, exclusion criteria, and then assess if any of the numerator criteria are met.

First, I confirm the measurement period: the entire calendar year of 2026 (January 1, 2026, to December 31, 2026).

Next, I evaluate the denominator, which defines the eligible population.
*   **Age:** The member must be between 46 and 75 years old as of December 31, 2026. Member 40203 was born on January 8, 1974. Calculating their age as of December 31, 2026: 2026 - 1974 = 52 years. This age, 52, falls perfectly within the 46-75 range, so they meet this criterion.
*   **Enrollment:** The member needs continuous enrollment throughout 2026, with at most one gap of 45 days. The record indicates continuous enrollment from January 1, 2026, to December 31, 2026. This also meets the criterion.
Since both age and enrollment criteria are met, the member is in the eligible population (denominator).

Now, I must check if the member is excluded from the measure.
*   **E1: Colorectal cancer:** There is no indication of a colorectal cancer diagnosis.
*   **E2: Total colectomy:** There is no record of a total colectomy.
*   **E3: Hospice:** The member was not in hospice during 2026.
*   **E4: Age 66+ with frailty AND advanced illness:** The member is 52, so this exclusion does not apply.
As none of the exclusion criteria are met, the member remains eligible for compliance assessment.

The final step is to determine if the member meets any of the numerator criteria, which signify successful screening. I will review each option:
*   **N1: FOBT/FIT in 2026:** The member's screening history does not show a FOBT or FIT test performed in 2026.
*   **N2: Stool DNA test in 2024, 2025, or 2026 (3-year window):** The member's history shows a stool DNA test performed on September 17, 2024. The specification defines this window as "during 2026 or the two years prior," meaning the calendar years 2024, 2025, and 2026. Since the test was in 2024, it falls squarely within this required three-year window. This criterion is met.

Because I found a numerator criterion met (N2), I don't need to evaluate N3, N4, or N5 further for compliance, although I note they were not performed.

Therefore, the member is deemed "compliant."

For the "reason" field, it needs to be a concise, single sentence under 30 words, specifying the criterion or date that led to compliance. My thought process leads me to state that the compliance is due to the stool DNA test performed on the specific date, as that is the decisive factor.

I will refine the reason to be precise: "The member is compliant due to a stool DNA test performed on 2024-09-17, which falls within the required three-year screening window." This sentence is 20 words long, clearly states the reason and the date, and fulfills all requirements.

Finally, I package this into the required JSON format:

```json
{
  "status": "compliant",
  "reason": "The member is compliant due to a stool DNA test performed on 2024-09-17, which falls within the required three-year screening window."
}
```

**My Thought Process for QM-CRC Compliance**

Alright, let's break down this member's situation for the QM-CRC measure.

First, the basics:
*   **Measure:** QM-CRC (Colorectal Cancer Screening). This is the context for everything.
*   **Measurement Year:** 2026-01-01 through 2026-12-31. This sets the timeframe for evaluating compliance and the look-back periods.
*   **Member ID:** 40203.
*   **Date of Birth (DOB):** 1974-01-08.
*   **Age on 2026-12-31:** Calculating this is straightforward: 2026 - 1974 = 52. So, on the last day of the measurement year, the member is 52 years old.
*   **Continuous Enrollment:** The member was continuously enrolled from 2026-01-01 to 2026-12-31. This means they met the full year enrollment requirement without any significant gaps.

Now, let's check the criteria to determine if the member is in the denominator (meaning they are eligible for screening during the measurement year):

1.  **Age:** The measure requires the member to be between 46 and 75 years old on 2026-12-31. My calculation shows the member is 52, which falls perfectly within this range. (Met)
2.  **Continuous Enrollment:** The requirement is full enrollment for the measurement year with no more than one gap of 45 days. Since this member was enrolled for the *entire* year with no gaps, this criterion is met. (Met)

*   **Result for Denominator:** Based on age and enrollment, the member belongs in the denominator.

Next, I need to check for any exclusion criteria that would remove the member from the denominator:

1.  **E1 (Colorectal Cancer):** No record of this.
2.  **E2 (Total colectomy):** No record of this.
3.  **E3 (Hospice):** No record of this.
4.  **E4 (Age 66+ AND frailty/advanced illness):** The member is 52, which is *not* 66 or older. Therefore, this exclusion criterion is not applicable.

*   **Result for Exclusions:** The member is not excluded from the denominator.

Now, the crucial part: determining if the member is compliant (i.e., met the numerator requirement). I'll review the numerator options:

1.  **N1 (FOBT/FIT during 2026):** No record of this test within the measurement year.
2.  **N2 (Stool DNA test during 2026 or the two years prior, i.e., 2024-2026):**
    *   The member had a Stool DNA test on **2024-09-17**.
    *   The required window for this test is "during 2026 or the two years prior." This translates to the calendar years 2026, 2025, and 2024.
    *   Since the test date of 2024-09-17 falls within the year 2024, it is within the three-year look-back window. (Met)
3.  **N3 (Flexible sigmoidoscopy):** No record of this.
4.  **N4 (CT colonography):** No record of this.
5.  **N5 (Colonoscopy):** No record of this.

*   **Result for Numerator:** The member met the numerator requirement through the Stool DNA test (N2).

Therefore, the overall status is **compliant**.

The reason for compliance is straightforward: the member completed a Stool DNA test on 2024-09-17, and this date falls within the necessary three-year look-back period that includes 2024, 2025, and 2026 for the measurement year.

A quick check on the required JSON keys: the prompt specifies `status` and `reason` for QM-CRC. It also explicitly states that the additional keys (`met_7_day`, `met_30_day`) are only for measures drawn from QM-FUM, which this is not.

Final assembly for the output:

```json
{
  "status": "compliant",
  "reason": "The member is compliant due to a stool DNA test on 2024-09-17, which falls within the required three-year look-back window."
}
```

I've ensured the reason is concise, under 30 words, and accurately reflects the compliance.

```json
{
  "status": "compliant",
  "reason": "The member is compliant due to a stool DNA test on 2024-09-17, which falls within the required three-year look-back window."
}
```

**My Thought Process for Assessing Colorectal Cancer Screening (QM-CRC) Compliance**

Alright, let's break down this colorectal cancer screening measure, QM-CRC, for this specific member. My primary goal here is to determine if this individual is compliant for the 2026 measurement year, meaning they've met the screening requirements.

First, I've established the core parameters of the measure. The measurement year is clearly defined as January 1, 2026, through December 31, 2026.

Next, I need to identify who is even eligible to be considered for this measure. The denominator dictates this: the member must be between 46 and 75 years old as of the end of the measurement year (December 31, 2026). Additionally, they need to have been continuously enrolled for the entire measurement year, with a very minor allowance for a single gap of no more than 45 days.

Then, I move on to the numerator – what constitutes a successful screening? There are several pathways a member can satisfy this. They could have had a fecal occult blood test (FOBT) or fecal immunochemical test (FIT) in 2026 (N1). Alternatively, a stool DNA test performed in 2024, 2025, or 2026 (a three-year look-back window) would count (N2). More involved procedures also count, but with longer look-back periods: a flexible sigmoidoscopy in 2022-2026 (five-year window, N3), a CT colonography in 2022-2026 (five-year window, N4), or a colonoscopy in 2017-2026 (a ten-year window, N5).

Of course, there are also specific reasons why a member might be excluded from the measure, regardless of screening. These include having a diagnosis of colorectal cancer (ICD codes C18-C21) at any point up to the end of the measurement year (E1). A history of a total colectomy before the end of the measurement year also excludes them (E2). If they were in hospice care during the 2026 measurement year, they are out (E3). Finally, individuals aged 66 and older who are identified as frail or having advanced illness in 2026 are excluded (E4).

Now, let's apply these rules to our specific member. Their ID is 40203, and their date of birth is January 8, 1974.

**Eligibility Assessment:**

*   **Age:** On December 31, 2026, their age would be 2026 minus 1974, which is 52. This falls squarely within the 46-75 age range required for the denominator. So far, so good.
*   **Enrolment:** Their enrolment record shows they were continuously enrolled from January 1, 2026, through December 31, 2026. This meets the continuous enrolment requirement with no gaps.
*   **Status:** Based on age and enrolment, this member is eligible for the denominator.

**Exclusion Assessment:**

Now, let's check if any exclusion criteria apply to this member:

*   **E1 (Cancer):** I see no mention of a diagnosis of colorectal cancer.
*   **E2 (Colectomy):** No history of a total colectomy is noted.
*   **E3 (Hospice):** There's no indication of hospice care during 2026.
*   **E4 (Age 66+ & Frailty/Illness):** Since the member is only 52, this exclusion criteria is not applicable.
*   **Status:** Therefore, this member is not excluded from the measure.

**Numerator Assessment:**

With eligibility confirmed and no exclusions found, I need to see if they meet any of the numerator requirements:

*   **N1 (FOBT/FIT in 2026):** I don't see any record of an FOBT or FIT performed in 2026.
*   **N2 (Stool DNA test in 2024-2026):** Ah, here we go. The member had a stool DNA test on September 17, 2024. The requirement is for a test within 2026 or the two years prior. This translates to tests performed in 2026, 2025, or 2024. Their test date of September 17, 2024, falls perfectly within this three-year window ending December 31, 2026.
*   **N3-N5:** Since they've already met a numerator criterion (N2), I don't need to assess the sigmoidoscopy, CT colonography, or colonoscopy options.

**Final Conclusion:**

Based on my review, the member meets all the necessary criteria. They are within the age range, have continuous enrolment, and crucially, have satisfied the numerator requirement through a stool DNA test performed on September 17, 2024, which is within the specified three-year look-back window for the 2026 measurement year. No exclusions apply.

The final output I'm building should reflect this. The required keys are 'status' and 'reason'. Since this is QM-CRC and not QM-FUM, I will *not* include the `met_7_day` or `met_30_day` keys, as per the instructions.

So, for the 'status', it's clearly "compliant". For the 'reason', I need a concise explanation. I'll articulate that the member is compliant because a stool DNA test was performed on 2024-09-17, which falls within the required three-year look-back window. I'll refine this to be precise and under the word limit.

My final output will be:
```json
{
  "status": "compliant",
  "reason": "The member is compliant because a stool DNA test was performed on 2024-09-17, within the three-year window ending 2026-12-31."
}
```
This reason is 22 words, one sentence, clearly states the finding and the specific criterion met. The logic holds, and all conditions are checked.

Okay, here's how I'm processing this member's record against the QM-CRC quality measure.

First, I need to establish if this individual even belongs in the group we're evaluating. That means checking their **eligibility**. The measure specifies an age range and continuous enrollment requirements. For age, I'm looking at their birthdate – January 8th, 1974 – and the end of the measurement year, December 31st, 2026. A quick calculation shows they'll be 52 at the end of 2026. The QM-CRC range is 46 to 75, and 52 comfortably falls within that. Next, continuous enrollment. Their record shows they were enrolled from January 1st, 2026, through December 31st, 2026, with no gaps, which perfectly meets the full measurement year requirement. So, yes, this member is definitely within the **denominator**.

Now, before I can declare them compliant, I must ensure they don't fall into any **exclusion** categories. I'll go through them one by one.
*   **E1 (Colorectal cancer):** The record explicitly states "No colorectal cancer," so this exclusion doesn't apply.
*   **E2 (Total colectomy):** Similarly, the record indicates "no colectomy," ruling out this exclusion.
*   **E3 (Hospice):** Again, the record confirms "no hospice," so this doesn't apply.
*   **E4 (Age 66+ with frailty and advanced illness):** The member is only 52, and this exclusion requires being 66 or older. Therefore, this exclusion is not met.
*   **Conclusion on exclusions:** The member is not excluded by any of these criteria.

Since they are eligible and not excluded, I now need to see if they meet any of the **numerator** criteria. This is where I determine if they've had a qualifying screening. I'll check each option, paying close attention to the specific look-back windows relative to December 31st, 2026.
*   **N1 (FOBT/FIT in 2026):** I'm not seeing any record of this specific test in 2026.
*   **N2 (Stool DNA test in 2026 or two years prior):** This is a three-year look-back window, from January 1st, 2024, to December 31st, 2026. Ah, here we go. The record shows a Stool DNA test was performed on September 17th, 2024. This date falls squarely within that three-year window. This criterion is met.
*   **N3 (Flexible sigmoidoscopy in 2026 or four years prior):** No record of this test is present.
*   **N4 (CT colonography in 2026 or four years prior):** I don't see any evidence of this test.
*   **N5 (Colonoscopy in 2026 or nine years prior):** No record of a colonoscopy is noted.

Having found that the member meets **numerator criterion N2**, I can now determine their **final status**. They are in the denominator, not excluded, and they've met a numerator requirement. Therefore, their status is **"compliant."**

To articulate this clearly, the **reason** for compliance is straightforward: the Stool DNA test performed in 2024 satisfies the three-year look-back period for that specific screening method.

Finally, I'll package this into the required JSON output. The `status` will be "compliant," and the `reason` will be a concise statement: "The member is compliant due to a stool DNA test in 2024, which meets the three-year look-back window for that screening."

Yes, this all looks consistent and accurate based on the data and the QM-CRC guidelines. I'm confident in this assessment.

Alright, let's break down how I'm approaching this evaluation for member 40203 against the QM-CRC quality measure for the 2026 measurement year.

First, I need to determine if this member is even *part* of the group we're looking at – that's the **denominator**. The measure is specifically for Colorectal Cancer Screening. The measurement year is the full calendar year 2026. For this member, born in January 1974, they'll be 52 by the end of 2026. The QM-CRC denominator requires individuals to be between 46 and 75 years old, so they fit that age bracket perfectly. Crucially, they also need to have been continuously enrolled for the entire measurement year, with no more than one short gap. The records show they were continuously enrolled throughout 2026. So, yes, they are in the denominator; they are eligible.

Next, I have to check if there are any reasons to *exclude* them, even if they are in the denominator. These are the **exclusion criteria**.
*   **E1:** Do they have a diagnosis of colorectal cancer (codes C18-C21) at any point up to the end of 2026? The record clearly states "No colorectal cancer." Good.
*   **E2:** Have they undergone a total colectomy at any point up to the end of 2026? The record states "No colectomy." Also good.
*   **E3:** Were they in hospice care at any time during the measurement year? The record says "no hospice." Check.
*   **E4:** This exclusion is for individuals 66 and older who also have frailty and advanced illness. Since this member is only 52, this exclusion simply doesn't apply.

So, based on those checks, this member is *not* excluded from the measure.

Now, since they are eligible and not excluded, I need to see if they meet the **numerator criteria** – meaning, did they actually *get* a qualifying screening? The measure allows for several types of screenings, each with its own look-back period, measured from the end of the measurement year (2026-12-31). I'm looking for *any one* of these:

*   **N1:** A fecal occult blood test (FOBT) or fecal immunochemical test (FIT) done specifically *during* 2026. I've reviewed the records, and there's no indication of this type of test in 2026.
*   **N2:** A stool DNA test. This has a longer look-back: it can be done in 2026 *or* in the two years prior, making it a three-year window from 2024-01-01 through 2026-12-31. I found a record of a Stool DNA test performed on **September 17, 2024**. This date falls squarely within that three-year look-back window. Bingo!
*   **N3:** A flexible sigmoidoscopy. This has a five-year look-back (2026 or the four years prior). No record of this.
*   **N4:** A CT colonography. Also a five-year look-back. No record of this either.
*   **N5:** A colonoscopy. This has the longest look-back, ten years (2026 or the nine years prior). The member record explicitly states "No colonoscopy on record."

Therefore, since the member met the stool DNA test criterion (N2) with their 2024 test, they have successfully met the numerator requirements.

My **final determination** is that the member is **compliant**. The **reason** is straightforward: they had a stool DNA test within the required three-year look-back period.

All the logic holds, the steps are covered, and the data supports the conclusion. I'll now assemble this into the requested JSON format. It's looking like this:

```json
{
  "status": "compliant",
  "reason": "The member had a stool DNA test in 2024, which falls within the three-year look-back period for that screening."
}
```
The reason is clear, directly linked to the qualifying event, and the status accurately reflects the member's performance against the measure. The flow from eligibility to exclusion checks, and finally to numerator compliance, has been thorough. The JSON structure is correct as requested.

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

**Member Details:**
- DOB: 1974-01-08
- Age on 2026-12-31: 52 years old
- Enrolment: 2026-01-01 through 2026-12-31, continuous
- History: 2024-09-17 Stool DNA test, negative
- No colonoscopy, no colorectal cancer, no colectomy, no hospice

**Step 1: Eligible Population (Denominator)**
- Age: 46 through 75 as of 2026-12-31. Member is 52. ✓
- Continuous enrolment: full measurement year with no more than one gap of up to 45 days. Member has continuous enrolment 2026-01-01 through 2026-12-31. ✓

So the member enters the denominator.

**Step 2: Required Exclusions (evaluated before numerator)**
- E1: Colorectal cancer (C18-C21) any time on or before 2026-12-31. No colorectal cancer. ✗
- E2: Total colectomy any time on or before 2026-12-31. No colectomy. ✗
- E3: Hospice at any time during the measurement year. No hospice. ✗
- E4: Age 66 or older as of 2026-12-31 AND both frailty and advanced illness. Member is 52, not 66+. ✗

No exclusions met.

**Step 3: Numerator**
Look-back window measured back from 2026-12-31:
- N1: FOBT or FIT during 2026. None on record. ✗
- N2: Stool DNA test during 2026 or the two years prior (three-year window). The three-year window is 2024-01-01 through 2026-12-31. Member had a Stool DNA test on 2024-09-17. This falls within the window. ✓

So the member meets the numerator via N2.

**Conclusion:**
- Status: compliant
- Reason: The member is 52 with continuous enrolment and had a stool DNA test on 2024-09-17, within the three-year look-back window.

Let me make the reason under 30 words and specific.

"Stool DNA test on 2024-09-17 falls within the three-year look-back window for a 52-year-old member with continuous enrolment and no exclusions."

That's 23 words. Good.

The member is 52 years old on 2026-12-31. Eligible age is 46-75.
Enrolment is continuous 2026-01-01 through 2026-12-31.
So the member is in the denominator.

Exclusions:
E1. Colorectal cancer: No
E2. Total colectomy: No
E3. Hospice: No
E4. Age 66+ and frailty/advanced illness: No (age 52)

Numerator:
N1. FOBT/FIT during 2026: No
N2. Stool DNA test during 2026 or the two years prior (three-year window).
Measurement year is 2026. Three-year window is 2024, 2025, 2026.
History: 2024-09-17 Stool DNA test, negative.
This falls within the three-year window (2024-01-01 to 2026-12-31).
So N2 is met.

Status: compliant
Reason: Stool DNA test on 2024-09-17 satisfies the three-year look-back window for the numerator.

Let's double check the dates.
Measurement year: 2026.
Three-year window for Stool DNA: 2026 or the two years prior -> 2024, 2025, 2026.
2024-09-17 is in 2024. So it is within the window.
Age: 52 (born 1974-01-08, 2026-12-31 age is 52).
Eligible.
No exclusions.
Meets numerator.
Status: compliant.
Reason: Member had a stool DNA test on 2024-09-17, meeting the three-year look-back window.
Length of reason: "Member had a stool DNA test on 2024-09-17, meeting the three-year look-back window." (13 words).
Perfect.
No QM-FUM keys required.
JSON output only.

The task is to evaluate a member against the QM-CRC measure specification.

Member 40203:
- DOB: 1974-01-08
- Age on 2026-12-31: 52 years old. (Eligible age is 46-75).
- Enrolment: 2026-01-01 through 2026-12-31, continuous. (Meets continuous enrolment).
- History:
  - 2024-09-17: Stool DNA test, negative.
- No colonoscopy, no CRC, no colectomy, no hospice.

Denominator eligibility:
- Age 52 (46-75) -> Yes
- Continuous enrolment -> Yes
Enters denominator.

Exclusions:
- E1: CRC -> No
- E2: Colectomy -> No
- E3: Hospice -> No
- E4: Age >= 66 AND frailty/advanced illness -> No (Age 52)
Not excluded.

Numerator:
Look-back window from 2026-12-31:
- N1: FOBT/FIT during 2026 -> No
- N2: Stool DNA test during 2026 or the two years prior (three-year window: 2024-01-01 to 2026-12-31).
  - Member had Stool DNA test on 2024-09-17. This is within the 3-year window. -> Yes, meets N2.
- N3, N4, N5 -> No

Since the member meets N2, they are in the numerator.
Status: compliant.
Reason: Stool DNA test on 2024-09-17 falls within the three-year look-back window.

Let's double check the dates.
Measurement year: 2026.
Three-year window for Stool DNA: 2024-01-01 to 2026-12-31.
2024-09-17 is in 2024, so it is within the window.
Status: compliant.
Reason: Stool DNA test on 2024-09-17 satisfies the three-year look-back window for numerator criterion N2.
Length of reason: "Stool DNA test on 2024-09-17 satisfies the three-year look-back window for numerator criterion N2." (13 words).

Wait, the prompt says: "reason" string — one sentence, under 30 words, naming the specific criterion or date that decided it.
"Stool DNA test on 2024-09-17 satisfies the three-year look-back window for numerator criterion N2." -> 14 words. Perfect.

Let's check the JSON keys required:
"status"
"reason"

No QM-FUM keys needed.

```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 satisfies the three-year look-back window for numerator criterion N2."
}
```
Is the reason under 30 words? Yes.
Is it one sentence? Yes.
Does it name the specific criterion or date? Yes, both.
Status is exactly "compliant".
Everything looks good.
Space and format check:
```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 satisfies the three-year look-back window for numerator criterion N2."
}
```
Done.

Let me work through this member against measure QM-CRC.

Member 40203:
- DOB 1974-01-08, so 52 years old on 2026-12-31. Age 52 falls within 46-75. Eligible on age.
- Enrolment: 2026-01-01 through 2026-12-31, continuous. Eligible on enrolment.
- So the member is in the denominator.

Exclusions:
- E1: No colorectal cancer. Not excluded.
- E2: No colectomy. Not excluded.
- E3: No hospice. Not excluded.
- E4: Age 52, not 66+, not applicable. Not excluded.

Numerator:
- N1: FOBT/FIT during 2026 — none on record.
- N2: Stool DNA test during 2026 or the two years prior (three-year window). The measurement year is 2026, so the three-year window is 2024, 2025, 2026. Stool DNA test on 2024-09-17 — that falls in the window. So N2 is met.

Wait — "during 2026 or the two years prior (three-year window)". Two years prior to 2026 would be 2025 and 2024. So the window is 2024-01-01 through 2026-12-31. 2024-09-17 is within that. Yes, numerator met.

- N3, N4, N5: no procedures on record, but N2 is sufficient.

Status: compliant.
Reason: Stool DNA test 2024-09-17 within three-year look-back window (2024-2026), no exclusions apply.

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

Something like: "Stool DNA test on 2024-09-17 falls within the three-year numerator window (2024-2026); no exclusion applies."

Word count: let me count: Stool(1) DNA(2) test(3) on(4) 2024-09-17(5) falls(6) within(7) the(8) three-year(9) numerator(10) window(11) 2024-2026(12); no(13) exclusion(14) applies(15). Under 30 words. Good.

Required keys for QM-CRC: just "status" and "reason". The met_7_day/met_30_day keys are only for QM-FUM. So only those two keys.

Output: exactly one fenced JSON code block.

We need answer exactly JSON code block only. Need evaluate QM-CRC measure for member 40203.

Measure QM-CRC: Colorectal cancer screening. Measurement year 2026. Denominator: Age 46 through 75 as of 2026-12-31. Continuous enrolment full measurement year with no more than one gap up to 45 days. Numerator: any one by look-back window from 2026-12-31:
N1 FOBT/FIT during 2026.
N2 Stool DNA test during 2026 or two years prior (three-year window). So 2024,2025,2026? Let's parse: "during 2026 or the two years prior (three-year window)." As of 2026-12-31, window includes 2026, 2025, 2024. Stool DNA test on 2024-09-17. Is that within three-year window? Yes. Check date: 2024-09-17. Measurement year end 2026-12-31. Two years prior to 2026 means calendar years 2025 and 2024? Need careful: "during 2026 or the two years prior (three-year window)" Usually HEDIS CRC: "Stool DNA (sDNA) test during the measurement year or the two years prior to the measurement year." That means calendar years: measurement year (2026), prior year (2025), two years prior (2024). So test in 2024 is within window. N2 met. Stool DNA test negative does not matter? The numerator just requires test, not result. So compliant unless excluded or not eligible.

Exclusions required: E1 colorectal cancer (C18-C21) any time on or before 2026-12-31. None. E2 total colectomy any time on or before. None. E3 hospice any time during measurement year. None. E4 Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during measurement year. Member age 52 as of 2026-12-31, not 66 or older. So E4 no. No exclusions. Denominator: age 52 on 2026-12-31, within 46-75. Enrolment continuous 2026-01-01 through 2026-12-31. No gap. So in denominator, not excluded, meets numerator via N2 (stool DNA in three-year window). Status "compliant". Reason one sentence under 30 words naming specific criterion or date that decided it. Need mention age 52 and continuous enrolment and stool DNA 2024-09-17 within three-year window? The reason should name specific criterion or date that decided it. Probably "In denominator (age 52, continuous 2026 enrolment) and meets N2 via stool DNA test on 2024-09-17 in the three-year window." Need under 30 words. Let's count: In(1) denominator(2) (age(3) 52,(4) continuous(5) 2026(6) enrolment)(7) and(8) meets(9) N2(10) via(11) stool(12) DNA(13) test(14) on(15) 2024-09-17(16) in(17) the(18) three-year(19) window(20). 20 words. Good. We should ensure no extra keys. Wait task says Items drawn from measure QM-FUM require two further keys. This is QM-CRC, so only status and reason. Required JSON keys: status, reason. No met_7_day etc. Good.

Need output only fenced JSON code block and nothing else. Use proper JSON.

Let's verify age: DOB 1974-01-08. On 2026-12-31, age = 2026-1974 = 52 (birthday Jan 8 passed). Yes 52.

Check N2 window: "during 2026 or the two years prior (three-year window)." If measured back from 2026-12-31, three-year window could be 2023-12-31 through 2026-12-31? Wait look-back window measured back from 2026-12-31. For N2: "Stool DNA test during 2026 or the two years prior (three-year window)." Let's parse exactly: "by the look-back window measured back from 2026-12-31". For N2: "during 2026 or the two years prior (three-year window)." That phrase "during 2026 or the two years prior" means calendar years 2026, 2025, 2024. The parenthetical "three-year window" indicates those three calendar years. If instead it were a rolling 3-year window back from 2026-12-31, it would be 2023-12-31 to 2026-12-31, which includes 2024-09-17 anyway. Wait 2024-09-17 is after 2023-12-31, so also within rolling three-year. Let's check: 2026-12-31 minus 3 years = 2023-12-31. 2024-09-17 is within. So either interpretation, met. Good.

Need ensure "Stool DNA test, negative" does it count? Numerator just requires test. Some measures require result? Spec says "N2. Stool DNA test during 2026 or the two years prior". No result requirement. So count.

Exclusion E2 total colectomy any time on or before. None. E1 none. E3 hospice during MY none. E4 requires age >=66 as of 2026-12-31 AND frailty and advanced illness documented during MY. Age 52, no. So not excluded.

Status compliant. Reason: must be one sentence, under 30 words, naming specific criterion or date that decided it. Should we say "Meets numerator N2: stool DNA test on 2024-09-17 falls within the 2024–2026 three-year window; denominator met by age 52 and continuous 2026 enrolment." Count: Meets1 numerator2 N23 stool4 DNA5 test6 on7 2024-09-178 falls9 within10 the11 2024–202612 three-year13 window14 denominator15 met16 by17 age18 52? Actually "2024–2026" maybe one token. Let's count words: "Meets(1) numerator(2) N2:(3) stool(4) DNA(5) test(6) on(7) 2024-09-17(8) falls(9) within(10) the(11) 2024–2026(12) three-year(13) window;(14) denominator(15) met(16) by(17) age(18) 52(19) and(20) continuous(21) 2026(22) enrolment.(23)" Under 30. But reason should name specific criterion or date that decided it. It's decided by meeting numerator via N2 and being eligible. Maybe "Meets N2 via the 2024-09-17 stool DNA test in the three-year window; eligible by age 52 and continuous 2026 enrolment, with no exclusions." Count: Meets1 N22 via3 the4 2024-09-175 stool6 DNA7 test8 in9 the10 three-year11 window;12 eligible13 by14 age15 5216 and17 continuous18 202619 enrolment,20 with21 no22 exclusions.23 Under 30. It explicitly names dates/criteria. However reason says "one sentence, under 30 words, naming the specific criterion or date that decided it". Could simply: "Meets numerator N2 with the stool DNA test on 2024-09-17 in the three-year window; age 52 and continuous enrolment place her in the denominator." Count: Meets1 numerator2 N23 with4 the5 stool6 DNA7 test8 on9 2024-09-1710 in11 the12 three-year13 window;14 age15 5216 and17 continuous18 enrolment19 place20 her21 in22 the23 denominator.24 Under 30. Good. Maybe mention no exclusions? Not necessary but okay. Let's include essential. The status is compliant, so reason should reflect numerator met and eligibility. I'd use: "Meets N2 via the stool DNA test on 2024-09-17 in the three-year window; eligible by age 52 and continuous 2026 enrolment, with no exclusions." Count: Meets(1) N2(2) via(3) the(4) stool(5) DNA(6) test(7) on(8) 2024-09-17(9) in(10) the(11) three-year(12) window;(13) eligible(14) by(15) age(16) 52(17) and(18) continuous(19) 2026(20) enrolment,(21) with(22) no(23) exclusions.(24) Under 30. Good.

Need output exactly one fenced JSON code block. The code block must contain JSON object. No preamble. Use null? Not needed. Ensure JSON boolean none. Use double quotes.

Let's craft final:

```json
{
  "status": "compliant",
  "reason": "Meets N2 via the stool DNA test on 2024-09-17 in the three-year window; eligible by age 52 and continuous 2026 enrolment, with no exclusions."
}
```

Check JSON: The string contains a semicolon and comma, fine. No newline issues. It's valid JSON. Need ensure no trailing comma. Good.

Wait required keys exactly. For QM-CRC, no extra keys. Good.

Double-check that member never enters denominator? Age 46-75 as of 2026-12-31. DOB 1974 -> age 52. Yes. Continuous enrolment full year. Yes.

One nuance: "Stool DNA test, negative." Some CRC measures may require that a stool DNA test be "during the measurement year or the two years prior" and for negative results maybe a follow-up? No, numerator is screening completion, not result. In HEDIS, CRC numerator includes "sDNA test" any result. So compliant.

Another nuance: N2 says "Stool DNA test during 2026 or the two years prior (three-year window)." Does "two years prior" mean the two years before 2026 i.e. 2024 and 2025? Wait "prior" to 2026: the year prior to 2026 is 2025; the two years prior to 2026 are 2025 and 2024? Actually "the two years prior" to the measurement year 2026: If we say "during 2026 or the two years prior", that is 2026, 2025, 2024 (three years). Yes. 2024 is within. If someone interprets "two years prior" as 2024-12-31 to 2025-12-31? No.

But wait: Look-back window measured back from 2026-12-31. N3 flexible sigmoidoscopy during 2026 or four years prior (five-year window). That would be 2026,2025,2024,2023,2022. N5 colonoscopy during 2026 or nine years prior (ten-year window): 2017-2026. Good.

All fine.

Let's finalize. Must not output any commentary. Use fenced block with json. Ensure nothing else.

We need answer JSON for QM-CRC measure. Need determine status, reason. Let's parse.

Measure QM-CRC: Measurement year 2026-01-01 through 2026-12-31.
Denominator: Age 46 through 75 as of 2026-12-31. Member DOB 1974-01-08. On 2026-12-31, age = 2026 - 1974 = 52 (if birthday Jan 8, before Dec 31, yes 52). Meets age 46-75. Continuous enrolment full measurement year no gap >45 days: Enrolment 2026-01-01 through 2026-12-31 continuous. So enters denominator (eligible). Check exclusions before numerator.

Exclusions:
E1 colorectal cancer any time on or before 2026-12-31: none.
E2 total colectomy any time on or before: none.
E3 hospice during measurement year: none.
E4 Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during measurement year. Member age 52, so not 66 or older. Also no frailty/advanced illness. Not excluded.

Now numerator: any one of N1-N5 by look-back from 2026-12-31.
N1: FOBT or FIT during 2026. Record: No mention. History only 2024-09-17 Stool DNA test. No FIT/FOBT in 2026. So N1 false.
N2: Stool DNA test during 2026 or two years prior (three-year window). Window: 2024, 2025, 2026? Let's compute: measured back from 2026-12-31, stool DNA during 2026 or the two years prior (three-year window). Two years prior to 2026 are 2025 and 2024? Wait, if measurement year is 2026, "during 2026 or the two years prior" means years 2026, 2025, 2024. That is a three-year window: 2024-01-01 through 2026-12-31? Let's confirm: For a measurement year 2026, two years prior = 2024 and 2025. Actually "during 2026 or the two years prior" = 2026, 2025, 2024. Yes, three-year window. If the test is 2024-09-17, that falls within 2024 (two years prior? Wait 2026 minus 2 years = 2024; yes 2024 is two years prior to 2026 if we consider calendar years: prior years to 2026: 2025 is one year prior, 2024 is two years prior. So 2024 is included. So stool DNA test on 2024-09-17 is within three-year window. Thus N2 is met. It says stool DNA test, negative. Indeed N2: "Stool DNA test during 2026 or the two years prior (three-year window)." So yes compliant.

Need ensure no other conditions. The member had stool DNA test 2024-09-17. That's within window. No colonoscopy etc. Numerator met via N2. Status: compliant. Since in denominator, not excluded, meets numerator.

Reason: one sentence under 30 words naming specific criterion or date that decided it. Must name specific criterion or date. E.g., "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year window ending 2026-12-31." Count words: Met(1) numerator(2) N2(3) via(4) stool(5) DNA(6) test(7) on(8) 2024-09-17,(9) within(10) the(11) three-year(12) window(13) ending(14) 2026-12-31.(15) Under 30. Good. Or "Age 52 and continuous enrolment place member in denominator; numerator met by stool DNA test on 2024-09-17 under N2 three-year window." That's also fine. Need specific criterion or date that decided it. Since status compliant, the deciding criterion is N2 stool DNA test date. Need mention denominator? The reason should name specific criterion or date that decided it. It could be: "Numerator met under N2 by stool DNA test on 2024-09-17, within the three-year window; no exclusions." Word count: Numerator(1) met(2) under(3) N2(4) by(5) stool(6) DNA(7) test(8) on(9) 2024-09-17,(10) within(11) the(12) three-year(13) window;(14) no(15) exclusions.(16) Good.

But maybe need ensure no required keys for QM-FUM? Task says Items drawn from measure QM-FUM require two further keys. This is QM-CRC, so no met_7_day/met_30_day. Required JSON keys: only "status" and "reason". Yes.

Need double-check age calculation: DOB 1974-01-08, on 2026-12-31 is 52 years old (turned 52 on 2026-01-08). Age 46-75 inclusive, so eligible. Continuous enrolment: full year no gap.

Check exclusion E4: Age 66+ AND frailty+advanced illness. Age 52 no.

Check numerator N2: stool DNA test during 2026 or two years prior (three-year window). Let's ensure date 2024-09-17 is in window. The window is from 2024-01-01? Wait, "during 2026 or the two years prior (three-year window)" Could be interpreted as calendar years 2024, 2025, 2026. 2024-09-17 is in calendar year 2024, which is two years prior to 2026? Actually if we count back from 2026-12-31: the two years prior to 2026 are 2025 and 2024? Let's list: one year prior to 2026 is 2025; two years prior is 2024. Yes, so 2024 included. If "three-year window" measured back from 2026-12-31, that's 2023-12-31? Wait, careful: A three-year window back from 2026-12-31 would be from 2023-12-31 to 2026-12-31 (or 2024-01-01 to 2026-12-31 if calendar-based). But the spec says "during 2026 or the two years prior (three-year window)". The phrase "during 2026 or the two years prior" means the years 2026, 2025, 2024. That is a three-calendar-year window (2024, 2025, 2026). If they meant a full 36 months back from 2026-12-31, that would include part of 2023 (from 2023-12-31). But they explicitly parenthetically say "(three-year window)" and in other numerators: N3 flexible sigmoidoscopy during 2026 or four years prior (five-year window) -> years 2026, 2025, 2024, 2023, 2022 (five calendar years). N5 colonoscopy during 2026 or nine years prior (ten-year window) -> 2026 plus 2017-2025? Wait colonoscopy: during 2026 or the nine years prior (ten-year window). Nine years prior to 2026: 2017? Let's count: 2025 (1), 2024 (2), 2023 (3), 2022 (4), 2021 (5), 2020 (6), 2019 (7), 2018 (8), 2017 (9). Plus 2026 = ten-year window: 2017-2026. That's calendar years. So for N2: two years prior = 2025 (1), 2024 (2). Plus 2026 = 2024,2025,2026. Good. 2024-09-17 is in 2024, included.

Wait, check: In HEDIS, CRC screening: "Stool DNA (sDNA) test during the measurement year or the two years prior." That's a three-year window. In HEDIS, the test must be during the measurement year or the two years prior to the measurement year. If measurement year 2026, then years 2026, 2025, 2024. A service on 2024-09-17 is in 2024, yes. So compliant.

Now status: compliant. Reason sentence. Need JSON only.

Let's craft final JSON:

{
  "status": "compliant",
  "reason": "Numerator met under N2 by stool DNA test on 2024-09-17, within the three-year window; no exclusions."
}

Check word count: Numerator(1) met(2) under(3) N2(4) by(5) stool(6) DNA(7) test(8) on(9) 2024-09-17,(10) within(11) the(12) three-year(13) window;(14) no(15) exclusions.(16) Under 30. It names criterion N2 and date. Good.

But is it necessary to mention age/enrollment? The reason should name the specific criterion or date that decided it. The deciding criterion for compliant is numerator N2; denominator eligibility is assumed but maybe mention? It says "naming the specific criterion or date that decided it". The status is compliant, meaning in denominator, not excluded, meets numerator. The final deciding factor is the numerator criterion N2 date. The reason can focus on that. But to be safe, we might say: "Age 52 and continuous enrolment in denominator; numerator met by stool DNA test on 2024-09-17 under N2." Let's count: Age(1) 52(2) and(3) continuous(4) enrolment(5) in(6) denominator;(7) numerator(8) met(9) by(10) stool(11) DNA(12) test(13) on(14) 2024-09-17(15) under(16) N2.(17) That's clear. But maybe "Age 52" uses age not criterion? The age criterion is 46-75. The date decided? Let's use: "In denominator by age 52 and continuous enrolment; numerator met under N2 by stool DNA test on 2024-09-17." Count: In(1) denominator(2) by(3) age(4) 52(5) and(6) continuous(7) enrolment;(8) numerator(9) met(10) under(11) N2(12) by(13) stool(14) DNA(15) test(16) on(17) 2024-09-17.(18) Under 30. That names criterion N2 and date. It also notes denominator. I think the instruction: "one sentence, under 30 words, naming the specific criterion or date that decided it". For compliant, the specific criterion that decided numerator is N2, date 2024-09-17. The denominator eligibility criteria (age, enrolment) also must be true, but they didn't decide against; the reason can just state the deciding compliance. Let's maybe keep simpler: "Numerator met under N2 by stool DNA test on 2024-09-17, within the three-year window; no exclusions." That's enough.

Wait, check if there is any subtle issue: The stool DNA test was "negative". Does the numerator require a negative result? It says "Stool DNA test during 2026 or the two years prior". No mention of result. So negative is fine. No need for result.

Check continuous enrolment: From 2026-01-01 through 2026-12-31, no gap. Yes.

Could there be an issue with age? Age as of 2026-12-31: DOB 1974-01-08. Let's calculate precisely: 2026-12-31 minus 1974-01-08 = 52 years, 11 months, 23 days? Actually from 1974-01-08 to 2026-01-08 is 52 years. Then to 2026-12-31 is additional 11 months 23 days, so age 52. Yes.

Now ensure JSON formatting: exactly one fenced JSON code block, nothing else. Use null? No. No met_7_day etc. Output:

```json
{
  "status": "compliant",
  "reason": "Numerator met under N2 by stool DNA test on 2024-09-17, within the three-year window; no exclusions."
}
```

Wait, is the reason a single sentence? It has a semicolon, but it's one sentence? "Numerator met ...; no exclusions." That's a compound sentence with semicolon, still one sentence. Under 30 words. Good.

Need check if "no exclusions" is needed? The status compliant requires not excluded. The reason naming criterion that decided it: the numerator N2. Could be: "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year look-back window." Let's count: Met(1) numerator(2) N2(3) via(4) stool(5) DNA(6) test(7) on(8) 2024-09-17,(9) within(10) the(11) three-year(12) look-back(13) window.(14) That's 14 words. It doesn't mention denominator or exclusions, but status already encodes that. The task says reason: one sentence naming specific criterion or date that decided it. The criterion that decided compliance is N2, date is 2024-09-17. That's perfect. Let's use that maybe. But to be thorough, we can mention no exclusions? The instruction says naming the specific criterion or date that decided it. Since exclusions are evaluated before numerator, and none applied, the deciding factor is numerator. If I say "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year window." That names criterion N2 and date. It doesn't mention exclusions, but status compliant implies none. I think either is fine. Let's use a sentence that includes N2 and date and window: "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year window ending 2026-12-31." Count: Met(1) numerator(2) N2(3) via(4) stool(5) DNA(6) test(7) on(8) 2024-09-17,(9) within(10) the(11) three-year(12) window(13) ending(14) 2026-12-31.(15) Good. This is precise. It doesn't mention no exclusions, but fine. Let's output that.

Wait: Should I say "Met numerator N2" or "Numerator met under N2"? Both okay. The reason must be a string. Use exactly: "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year window ending 2026-12-31."

Let's verify there is no need for met_7_day etc. The prompt says Items drawn from measure QM-FUM require two further keys. This is QM-CRC, so no. Required keys are status and reason only. Do not add keys.

Final answer exactly:

```json
{
  "status": "compliant",
  "reason": "Met numerator N2 via stool DNA test on 2024-09-17, within the three-year window ending 2026-12-31."
}
```
Wait, is "three-year window ending 2026-12-31" accurate? The window includes 2024, 2025, 2026. It ends on 2026-12-31. Yes.
Check: N2 says "during 2026 or the two years prior (three-year window)". The window is 2024-2026, ending 2026-12-31. Good.

One more check: The enrolment is 2026-01-01 through 2026-12-31 continuous. The member is 52 on 2026-12-31. Denominator requires age 46 through 75 as of 2026-12-31. Yes.

Everything set.

We need answer JSON for quality measure logic. We have QM-CRC. Need status, reason, maybe additional keys? The task says items drawn from measure QM-FUM require further keys met_7_day, met_30_day. For QM-CRC no additional keys required. Required JSON keys: status, reason. Maybe only those two. The task family says Required JSON keys: status, reason. It mentions QM-FUM require two further keys. Since this is QM-CRC, we only include status and reason, not met_7_day/met_30_day. Need determine member status.

Let's parse member record:
Member 40203, DOB 1974-01-08. Age on 2026-12-31: 2026 - 1974 = 52; birthday Jan 8, so on Dec 31 2026 age 52. Within 46 through 75 inclusive? Yes, 46-75.
Continuous enrolment: 2026-01-01 through 2026-12-31, continuous. Full measurement year, no gap or one gap up to 45 days. So eligible population met (denominator). No enrollment issues.
Exclusions evaluated before numerator:
E1: Colorectal cancer any time on or before 2026-12-31: no.
E2: Total colectomy: no.
E3: Hospice at any time during measurement year: no.
E4: Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during measurement year. Member is 52, not age 66 or older, so E4 not met. Thus no exclusions. So not excluded.

Now numerator: any one of N1-N5 by look-back window measured back from 2026-12-31.
N1: FOBT or FIT during 2026. History only has 2024-09-17 Stool DNA test, negative. No FOBT/FIT in 2026. So N1 not met.
N2: Stool DNA test during 2026 or the two years prior (three-year window). Let's parse: "during 2026 or the two years prior (three-year window)" measured back from 2026-12-31. Three-year window includes 2026, 2025, 2024? Need be precise: measurement year 2026 (Jan 1 - Dec 31). Two years prior: 2025 and 2024? The look-back window measured back from 2026-12-31. If stool DNA test during 2026 or the two years prior (three-year window). Typically for CRC screening HEDIS measure, stool DNA (sDNA-FIT) every 3 years: during the measurement year or the two years prior. That means tests in 2024, 2025, or 2026. The date 2024-09-17 is in 2024, which is two years prior to 2026? Wait 2026 minus 2 = 2024; yes 2024 is two years prior. Since measurement year is 2026, two years prior are 2025 and 2024? Let's think: Year prior to 2026 is 2025. Two years prior to 2026 is 2024. So a test on 2024-09-17 is within the three-year window (2024-2026). The phrase "during 2026 or the two years prior" means service dates in 2026, 2025, or 2024. The record has 2024-09-17, stool DNA test, negative. That meets N2 (Stool DNA test during 2026 or the two years prior). Need ensure the test was within look-back window measured back from 2026-12-31: The window is 2024-01-01 through 2026-12-31? Or from 2024-01-01? Let's check: back from 2026-12-31 three years. Three years back from 2026-12-31 is 2023-12-31? Actually if measured back from Dec 31, 2026, a three-year window could be 2024-01-01 through 2026-12-31 (if inclusive of three calendar years: 2024, 2025, 2026) or from 2023-12-31 to 2026-12-31 if exactly 3 years back by date? Let's examine wording: "by the look-back window measured back from 2026-12-31: N2. Stool DNA test during 2026 or the two years prior (three-year window)." They explicitly define three-year window as during 2026 or the two years prior. "Two years prior" to measurement year 2026: calendar years 2025 and 2024. Since 2026 is one year, plus two prior = three calendar years: 2026, 2025, 2024. So test date 2024-09-17 is within 2024, which is in the window. So N2 met. Therefore numerator met. Member is in denominator, not excluded, meets numerator -> status compliant.

Need reason: one sentence, under 30 words, naming specific criterion or date that decided it. The deciding criterion: Age 52 and continuous enrolment eligible; numerator met by N2 stool DNA test on 2024-09-17 within three-year window (2024-2026). Need mention no exclusions. Need keep under 30 words. Let's craft:
"Eligible at age 52 with continuous 2026 enrolment, no exclusions, and numerator met by stool DNA test on 2024-09-17 in the three-year window."
Word count: Eligible(1) at(2) age(3) 52(4) with(5) continuous(6) 2026(7) enrolment,(8) no(9) exclusions,(10) and(11) numerator(12) met(13) by(14) stool(15) DNA(16) test(17) on(18) 2024-09-17(19) in(20) the(21) three-year(22) window.(23). Under 30. Good. It names criterion/date. It says decided it. The status is compliant.

Check if any nuance: N2 is stool DNA test during 2026 or the two years prior. The test occurred 2024-09-17, negative. It is a stool DNA test. Yes. There is no colonoscopy on record, no other test. So compliant.

Potential issue: Age 46 through 75 as of 2026-12-31. Born 1974-01-08. Age on 2026-12-31: Let's compute exactly: 2026-12-31 minus 1974-01-08 = 52 years, 11 months, 23 days. So 52. Good.

Continuous enrollment: 2026-01-01 through 2026-12-31 continuous. Meets full measurement year.

Exclusion E4: Age 66 or older as of 2026-12-31 AND frailty and advanced illness. Not 66. So no.

Thus status compliant, reason as above. Need output exactly one fenced JSON code block and nothing else. No preamble. Keys: status, reason. Should we include met_7_day, met_30_day? Task says: Items drawn from measure QM-FUM require two further keys: met_7_day, met_30_day. For QM-CRC, no. It says "Include every required key. Do not add keys that were not asked for." So we must NOT include met_7_day/met_30_day. Only status and reason.

Need ensure JSON valid. Status string exactly "compliant". Reason string. Use double quotes. No trailing commas.

Let's double-check the stool DNA test date and window. Measurement year: 2026-01-01 through 2026-12-31. Numerator N2: "Stool DNA test during 2026 or the two years prior (three-year window)." The two years prior to 2026 are 2025 and 2024. It doesn't say "calendar years", but "during 2026 or the two years prior". If we interpret "the two years prior" as the 24-month period before 2026-01-01? Wait "during 2026 or the two years prior" could mean dates from 2024-01-01 through 2026-12-31 (three calendar years) or from 2024-01-01? Let's think of HEDIS. In HEDIS, for colorectal cancer screening, the sDNA test (stool DNA) is recommended every 3 years. The measure looks for a stool DNA test during the measurement year or the two years prior to the measurement year. The "two years prior" means the two calendar years before the measurement year. So for MY 2026, the prior years are 2025 and 2024. So test in 2024 counts. If the test had been in 2023, it would be three years prior, not count. So 2024-09-17 counts. Good.

Check if "negative" result matters? No, numerator just requires test. It was negative, no cancer. It doesn't exclude. Good.

Now, reason: "Eligible at age 52 with continuous 2026 enrolment, no exclusions, and numerator met by stool DNA test on 2024-09-17 in the three-year window." Is "2026 enrolment" okay? It says continuous enrolment: the full measurement year. Yes.

Maybe reason should name the specific numerator criterion N2? The instructions: "naming the specific criterion or date that decided it". We should name N2 or the stool DNA three-year window. Could say "Numerator N2 met by stool DNA test on 2024-09-17 within the 2024-2026 window; eligible at age 52 with continuous enrolment and no exclusions." Let's count words: Numerator(1) N2(2) met(3) by(4) stool(5) DNA(6) test(7) on(8) 2024-09-17(9) within(10) the(11) 2024-2026(12) window;(13) eligible(14) at(15) age(16) 52(17) with(18) continuous(19) enrolment(20) and(21) no(22) exclusions.(23). Good. It names criterion (N2) and date. Maybe mention denominator eligibility? It says "specific criterion or date that decided it". The decision is compliant. The deciding criteria: age 52, continuous enrolment, no exclusions, N2 met. We can mention all. Under 30 words.

Let's check: "Denominator eligible at age 52 with continuous 2026 enrolment; no exclusions; numerator met via N2 stool DNA test on 2024-09-17 in three-year window." Word count: Denominator(1) eligible(2) at(3) age(4) 52(5) with(6) continuous(7) 2026(8) enrolment;(9) no(10) exclusions;(11) numerator(12) met(13) via(14) N2(15) stool(16) DNA(17) test(18) on(19) 2024-09-17(20) in(21) three-year(22) window.(23). That's 23 words. Good. It says N2. It names date. Use "via N2 stool DNA test" maybe "via N2 (stool DNA) test". But JSON string.

Wait: status values: "compliant" in denominator, not excluded, and meets numerator. Yes.

One more nuance: The numerator N2 says "Stool DNA test during 2026 or the two years prior (three-year window)." Is a negative stool DNA test a "Stool DNA test"? Yes. Also is the test "during 2026 or the two years prior" meaning the test date must be on or after 2024-01-01? Since 2024 is two years prior, yes. 2024-09-17 is after 2024-01-01. Good.

Let's ensure no other keys. Output:

```json
{
  "status": "compliant",
  "reason": "Denominator eligible at age 52 with continuous 2026 enrolment; no exclusions; numerator met via N2 stool DNA test on 2024-09-17 in three-year window."
}
```

Check JSON: strings with semicolons fine. No newline issues. Use exactly one fenced block. No text after.

Let's consider if reason must be under 30 words. Count the final reason string words by splitting on spaces: "Denominator" (1) "eligible" (2) "at" (3) "age" (4) "52" (5) "with" (6) "continuous" (7) "2026" (8) "enrolment;" (9) "no" (10) "exclusions;" (11) "numerator" (12) "met" (13) "via" (14) "N2" (15) "stool" (16) "DNA" (17) "test" (18) "on" (19) "2024-09-17" (20) "in" (21) "three-year" (22) "window." (23). Yes 23 words. Under 30.

Maybe remove semicolon punctuation? It's fine. "enrolment" spelling? Provided glossary uses enrolment? The measure text: "Continuous enrolment" with British spelling. We can use "enrollment" or "enrolment"? The prompt uses "Continuous enrolment:" and "Enrolment:" in member record? Actually member record: "Enrolment: 2026-01-01 through 2026-12-31, continuous." It uses "Enrolment". So use "enrolment" to match. Good.

Need ensure date format ISO? Reason includes date 2024-09-17, which is ISO. Good. Money not involved.

Now final answer.

The user wants me to evaluate a member against the QM-CRC (Colorectal Cancer Screening) measure specification.

Let me break down the member record and measure:

**Member:**
- DOB: 1974-01-08
- Age on 2026-12-31: 52 years old (within 46-75 range)
- Enrollment: 2026-01-01 through 2026-12-31, continuous (no gaps mentioned)
- History: 
  - 2024-09-17: Stool DNA test, negative
  - No colonoscopy on record
  - No colorectal cancer, no colectomy, no hospice

**Measure QM-CRC:**
- Measurement year: 2026-01-01 through 2026-12-31
- Denominator: Age 46-75 as of 2026-12-31, continuous enrollment full measurement year with no more than one gap up to 45 days.
- Numerator options:
  - N1: FOBT or FIT during 2026
  - N2: Stool DNA test during 2026 or the two years prior (three-year window: 2024-01-01 through 2026-12-31)
  - N3: Flexible sigmoidoscopy during 2026 or four years prior (five-year window: 2022-01-01 through 2026-12-31)
  - N4: CT colonography during 2026 or four years prior (five-year window: 2022-01-01 through 2026-12-31)
  - N5: Colonoscopy during 2026 or nine years prior (ten-year window: 2017-01-01 through 2026-12-31)
- Required Exclusions:
  - E1: Colorectal cancer (C18-C21) any time on or before 2026-12-31 - NOT PRESENT
  - E2: Total colectomy any time on or before 2026-12-31 - NOT PRESENT
  - E3: Hospice at any time during measurement year - NOT PRESENT
  - E4: Age 66+ as of 2026-12-31 AND both frailty and advanced illness documented during measurement year - Member is 52, so not applicable.

**Analysis:**
1. Is the member in the denominator? 
   - Age 52 on 2026-12-31: Yes (46-75)
   - Enrollment: continuous 2026-01-01 through 2026-12-31: Yes
   - Status: eligible (in denominator)

2. Any exclusions?
   - E1, E2, E3, E4: None apply. So not excluded.

3. Numerator?
   - Check N2: Stool DNA test during 2026 or the two years prior (three-year window: 2024-01-01 to 2026-12-31).
   - Member had Stool DNA test on 2024-09-17. This falls within the window.
   - Therefore, numerator is met.

So status should be "compliant".
Reason: Something like "Stool DNA test on 2024-09-17 within three-year look-back window." or similar, under 30 words.

Wait, let me double check the measure specification wording for N2:
"N2. Stool DNA test during 2026 or the two years prior (three-year window)."

The look-back window measured back from 2026-12-31:
- During 2026: 2026-01-01 to 2026-12-31
- Two years prior: 2025 and 2024? Wait, "two years prior" to 2026 means 2025 and 2024?
Actually, "during 2026 or the two years prior (three-year window)". 
If measured back from 2026-12-31, two years prior would be 2024-12-31? Or is it calendar years?

The specification says: "Stool DNA test during 2026 or the two years prior (three-year window)."
Usually in HEDIS-style measures, this means the test occurred between 2024-01-01 and 2026-12-31 (a three-year window). Or it could mean 2024, 2025, and 2026 calendar years.

But regardless, 2024-09-17 is within 2024, which is one of the two years prior to 2026. So it's definitely in the window.

Let me verify: "during 2026 or the two years prior" - this means calendar year 2026, or calendar years 2025 or 2024. So 2024-09-17 is in 2024, which is one of the two years prior. So yes, numerator met.

Actually, looking carefully: the specification says "by the look-back window measured back from 2026-12-31". This could mean the window is exactly 3 years back from 2026-12-31, i.e., 2024-01-01 through 2026-12-31. Either way, 2024-09-17 is in.

Therefore: status = "compliant"

Required JSON keys:
- "status": "compliant"
- "reason": "Stool DNA test on 2024-09-17 falls within the three-year look-back window." (count words: Stool(1) DNA(2) test(3) on(4) 2024-09-17(5) falls(6) within(7) the(8) three-year(9) look-back(10) window(11). = 11 words. Good.)

Wait, the task says "Reason: string — one sentence, under 30 words, naming the specific criterion or date that decided it"

The specific criterion is N2. Should I mention N2? Probably good to mention.
"Stool DNA test on 2024-09-17 meets numerator criterion N2." (9 words)
"Member had stool DNA test on 2024-09-17 within three-year window." (10 words)

I'll go with something concise.

Let me make sure there are no tricks.
- Member age 52: meets denominator age 46-75.
- Enrollment continuous: meets.
- Stool DNA test 2024-09-17: meets N2.
- No exclusions apply.

So final JSON:
```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 meets numerator criterion N2."
}
```

Wait, is "2024-09-17" considered "during 2026 or the two years prior"? The two years prior to 2026 are 2025 and 2024. Yes. So 2024-09-17 is in 2024, which is within the two years prior. Correct.

Double-checking: could there be an issue with the test being "negative"? The measure doesn't say the test has to be positive or negative, just that it occurred. So negative is fine.

Everything looks good.

One final check: The task mentions "Items drawn from measure QM-FUM require two further keys: met_7_day, met_30_day". This is measure QM-CRC, so those keys are NOT required. The prompt says "Required JSON keys: 'status', 'reason'" and then specifically mentions QM-FUM requires further keys. Since this is QM-CRC, only status and reason are needed.

Wait, I should re-read: "Required JSON keys: 'status' string... 'reason' string... Items drawn from measure QM-FUM require two further keys..." This implies that for QM-CRC, only status and reason are required. I should not add extra keys.

Final answer:
```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 meets numerator criterion N2."
}
```

 We need to analyze QM-CRC measure for member 40203.

First, check denominator eligibility:
- Age: 46 through 75 years as of 2026-12-31. DOB 1974-01-08. Age on 2026-12-31: 2026 - 1974 = 52, and Dec 31 is after Jan 8, so age 52. 46 <= 52 <= 75. So age eligible.
- Continuous enrollment: 2026-01-01 through 2026-12-31. The prompt says "Enrolment: 2026-01-01 through 2026-12-31, continuous." The spec says "Continuous enrolment: the full measurement year with no more than one gap of up to 45 days." Since it's continuous for the full year, meets enrollment. So denominator eligible.

Now check exclusions:
- E1: Colorectal cancer (C18-C21) any time on or before 2026-12-31. Not on record. So no.
- E2: Total colectomy any time on or before 2026-12-31. Not on record. So no.
- E3: Hospice at any time during the measurement year. Not on record. So no.
- E4: Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during measurement year. Member is 52, so age < 66. Exclusion E4 does not apply.

So not excluded. Status will be either compliant or non_compliant.

Now check numerator:
Look back from 2026-12-31.

N1. FOBT or FIT during 2026. Record has no test in 2026. So no.
N2. Stool DNA test during 2026 or the two years prior (three-year window). The test was on 2024-09-17. The window is 2026, 2025, 2024 (from 2024-01-01 to 2026-12-31? Let's parse: "during 2026 or the two years prior (three-year window)". That means the window is the three-year period ending 2026-12-31: from 2024-01-01 to 2026-12-31. The test 2024-09-17 falls within that window. However, the spec says "Stool DNA test during 2026 or the two years prior". Usually that implies the test must be in 2024, 2025, or 2026. 2024-09-17 is in 2024, which is correct. So N2 is satisfied.

Wait, confirm nuance: "during 2026 or the two years prior (three-year window)". That means from 2024-01-01 to 2026-12-31 inclusive. The test date 2024-09-17 is within that window. So numerator met via N2.

Therefore status is "compliant". Reason: one sentence under 30 words naming specific criterion or date that decided it. Something like "Stool DNA test on 2024-09-17 meets numerator N2." Or "Stool DNA test within three-year window." Or "Met numerator N2 with stool DNA test on 2024-09-17." Keep under 30 words.

Let's count: "Met numerator N2 with stool DNA test on 2024-09-17." That's 9 words. Good.

Double-check no hidden issues. The member had a stool DNA test in 2024, negative. But measure likely doesn't require positive, just that test was performed. So yes.

Wait: measure is QM-CRC. The numerator items are by the look-back window measured back from 2026-12-31. N2: Stool DNA test during 2026 or the two years prior (three-year window). So 2024-09-17 is exactly within 2024, which is two years prior to 2026. Yes. (2026-2 = 2024). So compliant.

Now format JSON exactly. Required keys: "status", "reason". Since it's QM-CRC, not QM-FUM, we do NOT need met_7_day or met_30_day. The prompt says "Items drawn from measure QM-FUM require two further keys...". Since this is QM-CRC, only status and reason.

Thus:
```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 meets numerator N2."
}
```

Check length: 1 sentence, under 30 words. Yes.

Make sure no extra keys. No nulls needed.

Be careful: Is there any issue with continuous enrollment? The spec says "full measurement year with no more than one gap of up to 45 days." Enrollment says "2026-01-01 through 2026-12-31, continuous." That implies no gaps. So eligible.

Check exclusion E4 again: Age 66+ AND both frailty and advanced illness. Age is 52. Not applicable.

Everything seems straightforward.

One more nuance: N2 says "during 2026 or the two years prior (three-year window)". Does the stool DNA test negative count? The measure spec does not say the test must be positive. It just says "Stool DNA test". So the presence of the test suffices.

Thus answer is as above.

We must output exactly one fenced JSON block and nothing else. 

 We need to determine the quality measure status for member 40203 under QM-CRC. Let's parse the given specification.

Measurement year: 2026-01-01 through 2026-12-31.

Denominator criteria:
- Age: 46 through 75 years as of 2026-12-31.
- Continuous enrollment: full measurement year with no more than one gap up to 45 days.

Member: DOB 1974-01-08. Age as of 2026-12-31: 2026 - 1974 = 52, but we need to check if birthday has passed in 2026. 2026-12-31 is after 1974-01-08, so age is 52. 52 is between 46 and 75 inclusive. So age qualifies.

Enrollment: 2026-01-01 through 2026-12-31, continuous. That is full measurement year, no gaps. So denominator criteria met. So member is in denominator, not "not_eligible".

Required exclusions:
E1. Colorectal cancer (C18-C21) any time on or before 2026-12-31. Record says no colorectal cancer. So not excluded.
E2. Total colectomy any time on or before 2026-12-31. Record says no colectomy. So not excluded.
E3. Hospice at any time during measurement year. Record says no hospice. So not excluded.
E4. Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during measurement year. Member is 52, not 66 or older. So not excluded.

Thus member is in denominator, not excluded.

Now numerator: any one of N1-N5 by lookback from 2026-12-31.

N1. FOBT or FIT during 2026. No record of this.
N2. Stool DNA test during 2026 or the two years prior (three-year window). Lookback window: from 2024-01-01 to 2026-12-31? Wait: "during 2026 or the two years prior (three-year window)". Usually means the three-year window ending 2026-12-31: 2024-01-01 through 2026-12-31. The record shows Stool DNA test on 2024-09-17. That falls within the three-year window. So N2 is met.

Thus numerator is met. Since not excluded, status is "compliant".

Reason: one sentence under 30 words naming specific criterion or date that decided it. Something like "Stool DNA test on 2024-09-17 meets numerator criterion N2." Let's count: "Stool DNA test on 2024-09-17 meets numerator criterion N2." That's 9 words? Let's count: Stool(1) DNA(2) test(3) on(4) 2024-09-17(5) meets(6) numerator(7) criterion(8) N2.(9). Under 30 words. Good.

We also need to keep in mind that no extra keys should be added. The required keys: "status", "reason". No "met_7_day" or "met_30_day" since this is QM-CRC, not QM-FUM.

Double-check: Stool DNA test date 2024-09-17. The lookback for N2 is "during 2026 or the two years prior (three-year window)". The three-year window measured back from 2026-12-31 includes 2024-01-01 through 2026-12-31. 2024-09-17 is within that. So yes.

Check if there is any trick about "negative" result? The spec doesn't mention result, just the test. So it counts.

Thus answer: status compliant, reason as above.

Need to output exactly one fenced JSON block with nothing else.

Make sure JSON is valid, keys exactly "status" and "reason".

Use JSON null? Not needed.

Do not include any extra commentary. Just the code block.

Let's produce the JSON.

We are asked to evaluate MEASURE QM-CRC for Member 40203.

First, check denominator eligibility:

- Age: Born 1974-01-08. On 2026-12-31, age = 52 (2026 - 1974 = 52). That's within 46-75. So eligible by age.
- Continuous enrolment: Enrolment from 2026-01-01 through 2026-12-31, no gaps. So meets continuous enrolment.

So member is in denominator.

Next, check exclusions:

E1. Colorectal cancer: none.
E2. Total colectomy: none.
E3. Hospice: none.
E4. Age 66+ and both frailty and advanced illness. Age is 52 < 66, so this exclusion does not apply.

No exclusion applies. So not excluded.

Now numerator:

Member has a stool DNA test on 2024-09-17. For N2, stool DNA test within 2026 or the two years prior, i.e., from 2024-01-01 to 2026-12-31? "during 2026 or the two years prior" – measurement year 2026, so look-back window: 2026, 2025, 2024. So three-year window: 2024 through 2026. The test was on 2024-09-17, which falls within that window. Yes, it qualifies.

So numerator met (N2).

No other exclusions.

Thus status: compliant.

Reason: "Stool DNA test on 2024-09-17 within three-year window (N2)."

Now, the output requires JSON with keys: "status", "reason". No mention of "met_7_day" or "met_30_day" because that's for QM-FUM; this is QM-CRC. So only status and reason.

So:

```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 meets numerator N2 (2024-2026 window)."
}
```

Make reason under 30 words. That's fine.

We are given measure QM-CRC (Colorectal Cancer Screening) with a member record. Let's check eligibility, exclusions, numerator step by step.

Member DOB: 1974-01-08, so age at 2026-12-31: 2026 - 1974 = 52 (birthday in January, so exactly 52). Age 52 falls within 46-75, so meets age criterion.

Enrolment: continuous from 2026-01-01 to 2026-12-31, no gaps, so meets continuous enrolment criterion. So eligible, not not_eligible.

Now exclusions:
E1: Colorectal cancer (C18-C21) any time on or before 2026-12-31. None.
E2: Total colectomy any time. None.
E3: Hospice during measurement year. None.
E4: Age 66 or older AND both frailty and advanced illness. Age 52, not 66+, so not applicable.

No exclusions met. So not excluded.

Numerator: Need any one of N1-N5 by lookback from 2026-12-31.
N1: FOBT/FIT during 2026. Not in record.
N2: Stool DNA test during 2026 or the two years prior (three-year window). For 2026-12-31, the three-year window would be from 2024-01-01 to 2026-12-31? Typically "during 2026 or the two years prior" means during measurement year or the two calendar years prior, so 2024, 2025, 2026. The member had stool DNA test on 2024-09-17. That falls within 2024, so yes, it qualifies as N2. There's no mention that it must be during measurement year exclusively; the window is measurement year or the two years prior. So N2 met.

Thus member meets numerator, no exclusions. Status should be "compliant".

Now we need reason: one sentence under 30 words naming specific criterion or date. Could say: Stool DNA test on 2024-09-17 satisfies numerator N2 within the three-year lookback window.

Check: The measure spec says N2: Stool DNA test during 2026 or the two years prior (three-year window). Two years prior means 2024 and 2025. So 2024-09-17 qualifies. So reason: "Stool DNA test on 2024-09-17 meets numerator N2 (three-year window)."

Under 30 words. Good.

Now for output: we need keys status, reason. No mention of additional keys for QM-FUM; that's only if the task says "Items drawn from measure QM-FUM require two further keys". This is QM-CRC, so no need for met_7_day, met_30_day. So just status and reason.

Thus output:

```json
{
  "status": "compliant",
  "reason": "Stool DNA test on 2024-09-17 satisfies numerator N2 within the three-year lookback window."
}
```

Let me work through this QM-CRC (Colorectal Cancer Screening) measure systematically.

**MEASUREMENT YEAR**: 2026-01-01 through 2026-12-31

**STEP 1: Check if member is in the DENOMINATOR (eligible population)**

Age check:
- Member DOB: 1974-01-08
- Age as of 2026-12-31: 2026 - 1974 = 52 years old
- Eligible age range: 46-75 years
- ✓ Member is 52, so eligible

Continuous enrolment check:
- Enrolment period stated: 2026-01-01 through 2026-12-31, continuous
- Requirement: full measurement year with no more than one gap of up to 45 days
- ✓ Member is continuously enrolled for the full measurement year

**RESULT**: Member IS in the denominator.

**STEP 2: Check REQUIRED EXCLUSIONS**

E1. Colorectal cancer (C18-C21) any time on or before 2026-12-31:
- Record states: "No colorectal cancer on record"
- ✗ Not excluded

E2. Total colectomy any time on or before 2026-12-31:
- Record states: "no colectomy"
- ✗ Not excluded

E3. Hospice at any time during the measurement year:
- Record states: "no hospice"
- ✗ Not excluded

E4. Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during the measurement year:
- Member is 52 years old as of 2026-12-31
- Age requirement: 66 or older
- Member does not meet age threshold
- ✗ Not excluded

**RESULT**: Member meets NO exclusions. NOT excluded from denominator.

**STEP 3: Check NUMERATOR**

At least one of these criteria needs to be met:

N1. Faecal occult blood test or faecal immunochemical test during 2026:
- No such test recorded in 2026
- ✗ Not met

N2. Stool DNA test during 2026 or the two years prior (window: 2024-01-01 through 2026-12-31):
- Record shows: "2024-09-17 Stool DNA test, negative"
- Falls within the qualifying three-year window

N3. Flexible sigmoidoscopy during 2026 or the four years prior (window: 2022-01-01 through 2026-12-31):
- Nothing recorded — ✗ Not met

N4. CT colonography during 2026 or the four years prior (window: 2022-01-01 through 2026-12-31):
- Nothing recorded — ✗ Not met

N5. Colonoscopy during 2026 or the nine years prior (window: 2017-01-01 through 2026-12-31):
- "No colonoscopy on record" — ✗ Not met

Numerator is satisfied through N2 alone — the 2024-09-17 stool DNA test falls squarely within the three-year lookback.

**FINAL DETERMINATION**: Member

is in the denominator, has no exclusions, and meets the numerator via the 2024-09-17 stool DNA test.

**Status: COMPLIANT**

Double-checking the N2 window: 2026 plus two years prior = 2024, 2025, 2026, so 2024-01-01 through 2026-12-31. Test date 2024-09-17 falls comfortably inside this range, confirming compliance.

**Reason**: "Stool DNA test dated 2024-09-17 satisfies three-year look-back for numerator." — concise, names the specific date and criterion.

09-17 satisfies N2 within the required look-back window." = 9 words. Good, settled.

```json
{
  "status": "compliant",
  "reason": "Stool DNA test dated 2024-09-17 satisfies N2 criterion."
}
```

Double-checking the window: N2 covers 2026 or the two years prior, meaning 2024-2026 total. 2024-09-17 falls within this range, confirming compliance.

Let me work through this systematically.

**MEMBER DETAILS:**
- DOB: 1974-01-08
- Age as of 2026-12-31: 52 years old
- Enrolment: 2026-01-01 through 2026-12-31, continuous (no gaps mentioned, so meets continuous enrolment requirement)
- No colorectal cancer, no colectomy, no hospice on record

**ELIGIBLE POPULATION (DENOMINATOR):**
1. Age: 46 through 75 years as of 2026-12-31
   - Member is 52 on 2026-12-31 ✓ (meets requirement)

2. Continuous enrolment: full measurement year with no more than one gap of up to 45 days
   - Member enrolled 2026-01-01 through 2026-12-31, continuous ✓ (meets requirement)

**Member IS in the denominator.**

**REQUIRED EXCLUSIONS:**
E1. Colorectal cancer (C18-C21) any time on or before 2026-12-31
   - No colorectal cancer on record ✗ (not excluded)

E2. Total colectomy any time on or before 2026-12-31
   - No colectomy on record ✗ (not excluded)

E3. Hospice at any time during the measurement year
   - No hospice on record ✗ (not excluded)

E4. Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during the measurement year
   - Member is 52 on 2026-12-31, so not 66 or older ✗ (not excluded)

**Member is NOT excluded.**

**NUMERATOR - Need to check if member meets ANY of N1-N5:**
N1 checks for an FOBT/FIT in 2026 — none found, so this doesn't apply. Moving to N2, the stool DNA test window spans 2024-01-01 through 2026-12-31, and there's a record dated 2024-09-17, which falls inside that range — so **N2 is satisfied**. Still worth checking N3 for flexible sigmoidoscopy, covering 2026 back through the prior four years.

No sigmoidoscopy shows up, so N3 fails. Same for N4 - CT colonography across the same window, nothing on file. N5's ten-year colonoscopy window (2017-2026) also comes back empty.

Since N2 alone is enough to satisfy the numerator, that's sufficient. The member fits denominator criteria, isn't excluded, and the 2024 stool DNA test clears the numerator requirement.

**STATUS: "compliant"**

**REASON:** Keeping it concise - "Stool DNA test 2024-09-17 within three-year look-back window (N2)." covers the key fact in under 30 words.

Checking the measurement year 2026 against N2's three-year window (2024-2026): the stool DNA test on 2024-09-17 falls squarely within 2024-01-01 through 2026-12-31, so the member qualifies as compliant.

```json
{
  "status": "compliant",
  "reason": "Stool DNA test 2024-09-17 satisfies N2 within three-year look-back window."
}
```

Let me work through this QM-CRC measure logic step by step.

**Member Information:**
- DOB: 1974-01-08
- Age on 2026-12-31: 52 years old
- Enrollment: 2026-01-01 through 2026-12-31, continuous (no gaps)
- History: Stool DNA test on 2024-09-17 (negative)
- No colonoscopy, cancer, colectomy, or hospice

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

Age requirement: 46-75 years as of 2026-12-31
- Member is 52 on 2026-12-31 ✓

Continuous enrollment: Full measurement year with no more than one gap of up to 45 days
- Enrolled 2026-01-01 through 2026-12-31, continuous ✓

**Member is in the denominator.**

**Step 2: Check Required Exclusions**

E1. Colorectal cancer (C18-C21) any time on or before 2026-12-31
- Not documented ✓ (not excluded by E1)

E2. Total colectomy any time on or before 2026-12-31
- Not documented ✓ (not excluded by E2)

E3. Hospice at any time during the measurement year
- Not documented ✓ (not excluded by E3)

E4. Age 66 or older as of 2026-12-31 AND both frailty and advanced illness documented during the measurement year
- Member is 52, not 66 or older ✓ (not excluded by E4)

**Member is not excluded.**

**Step 3: Check Numerator Compliance**

The member needs to meet at least one of N1-N5:
N1. FOBT/FIT during 2026 — nothing on file ✗

N2. Stool DNA test within a three-year lookback (2024-01-01 through 2026-12-31)
- The 2024-09-17 stool DNA test falls squarely in this window ✓
- **Numerator is satisfied here**, no need to check N3-N5 further.

**Status: COMPLIANT**

**Reason:** "Stool DNA test on 2024-09-17 meets N2 numerator within three-year window." (12 words)
