Out-of-pocket maximum caps the claim

**Adjudicating Claim 1: My Thought Process**

Alright, I've got Claim 1 in front of me, and my task is to meticulously adjudicate it against the provided plan document and the member's current accumulators. This means I need to figure out the exact financial breakdown for this specific claim, culminating in the final state of the member's deductibles and out-of-pocket maximums.

First things first, I need to calculate several key figures for this FINAL claim (which, in this instance, is Claim 1 itself):
*   `member_responsibility`: How much the member ultimately owes for this claim.
*   `plan_paid`: How much the insurance plan will cover.
*   `deductible_applied`: The portion of the allowed amount that goes towards satisfying the deductible.
*   `copay_amount`: Any fixed co-payment due.
*   `coinsurance_amount`: The member's share of costs after the deductible is met.
*   `ending_member_deductible`: The member's deductible balance after this claim.
*   `ending_member_oopm`: The member's out-of-pocket maximum balance after this claim.

I'll start by establishing the member's baseline financial standing *before* this claim. My initial accumulators tell me:
*   Member deductible: $1500.00
*   Member OOPM: $5400.00
*   Family deductible: $1500.00
*   Family OOPM: $5400.00

The plan itself has its own set of limits:
*   Individual Deductible: $1500.00
*   Individual OOPM: $6000.00
*   Coinsurance In-Network: 20% for the member, 80% for the plan.

Now, let's dive into Claim 1 details:
*   Service: Inpatient admission.
*   Network: In-network.
*   Billed Amount: $34960.00.
*   Allowed Amount: $18400.00. (Crucially, I'll be working with the allowed amount, not the billed amount, for calculations).

**Calculating the Deductible:**
The individual deductible limit is $1500.00. My records show the member has already met their $1500.00 deductible. Therefore, no portion of this claim's allowed amount will be applied to the deductible.
*   `deductible_applied` = $0.00.

**Calculating the Copay:**
I need to check the plan document for any specific copay for inpatient admissions. The document states that the Emergency Room has a $400 copay, but this is waived if the admission results in an inpatient stay. For inpatient services themselves, the plan indicates they are subject to the deductible and coinsurance. There's no specific, fixed copay for this type of inpatient admission.
*   `copay_amount` = $0.00.

**Calculating the Coinsurance:**
First, I need to determine the remaining allowed amount after the deductible has been accounted for. Since $0.00 was applied to the deductible, the entire allowed amount is available for coinsurance calculations.
Remaining allowed amount = $18400.00 (Allowed) - $0.00 (Deductible Applied) = $18400.00.
The member's coinsurance responsibility is 20%.
Calculated coinsurance = $18400.00 * 0.20 = $3680.00.

**Checking Against the Out-of-Pocket Maximum (OOPM):**
This is a critical step. The member's starting OOPM balance is $5400.00. The individual OOPM limit is $6000.00. This means the member has $6000.00 - $5400.00 = $600.00 of "room" left in their OOPM for this plan year.
The calculated coinsurance amount for this claim is $3680.00.
Since $3680.00 is greater than the remaining OOPM room ($600.00), the member's responsibility for coinsurance on this claim will be capped at $600.00. This $600.00 will then count towards their OOPM.
*   `coinsurance_amount` = $600.00.

**Calculating Total Member Responsibility:**
Now, I sum up all the components of the member's financial obligation for this claim:
Total Member Responsibility = `deductible_applied` + `copay_amount` + `coinsurance_amount`
Total Member Responsibility = $0.00 + $0.00 + $600.00 = $600.00.
*   `member_responsibility` = $600.00.

**Calculating Plan Paid Amount:**
The plan will pay the allowed amount minus the member's total responsibility.
Plan Paid = Allowed Amount - `member_responsibility`
Plan Paid = $18400.00 - $600.00 = $17800.00.
*   `plan_paid` = $17800.00.

**Determining Ending Accumulators:**
Finally, I update the member's accumulators based on this claim's adjudication:
*   Ending member deductible: Since $0.00 was applied, the deductible remains at its starting point.
    `ending_member_deductible` = $1500.00.
*   Ending member OOPM: The $600.00 of coinsurance paid by the member is added to their existing OOPM balance.
    `ending_member_oopm` = $5400.00 (Starting OOPM) + $600.00 (Coinsurance applied to OOPM) = $6000.00.

**Final Review and Formatting:**
I'll do a quick double-check. Allowed amount is $18400.00. Deductible is fully met. Coinsurance rate is 20%. The initial coinsurance calculation was $3680.00. The OOPM max is $6000.00, with a current balance of $5400.00, leaving $600.00 of room. This means the member can only pay a maximum of $600.00 towards coinsurance on this claim, which perfectly aligns with the OOPM limit. The plan pays the rest ($18400 - $600 = $17800). All amounts seem correct and are formatted to two decimal places as required.

The JSON output will be:
```json
{
  "member_responsibility": 600.00,
  "plan_paid": 17800.00,
  "deductible_applied": 0.00,
  "copay_amount": 0.00,
  "coinsurance_amount": 600.00,
  "ending_member_deductible": 1500.00,
  "ending_member_oopm": 6000.00
}
```
This entire process confirms that the member's responsibility for this claim is capped by their remaining out-of-pocket maximum, and the plan covers the remainder of the allowed amount. The logic appears sound and consistent with the provided plan details and accumulators.

**Adjudicating Claim 1: My Thought Process**

Alright, my task here is to meticulously adjudicate Claim 1, referencing the provided plan document and the member's current accumulator balances. I need to output the results in a specific JSON format, ensuring each of the required keys is present and all monetary values are formatted precisely to two decimal places.

First, let's establish the plan's core parameters for an individual in-network scenario. The deductible is $1500.00, and the out-of-pocket maximum (OOPM) is $6000.00. Coinsurance is set at 20% for in-network services.

Now, I'll examine the member's accumulators *before* this claim is processed. They've already met their individual deductible, having $1500.00 credited year-to-date. Similarly, they've accumulated $5400.00 towards their individual OOPM. The family accumulators mirror these, with $1500.00 credited to the family deductible and $5400.00 to the family OOPM.

Moving onto Claim 1 itself:
The service is an in-network inpatient admission with a billed charge of $34960.00 and an allowed amount of $18400.00.

Let's break down the financial impact:

1.  **Deductible Application:** The member's individual in-network deductible is $1500.00. Since they have already credited $1500.00 year-to-date, their remaining deductible is $0.00 ($1500.00 - $1500.00). Therefore, *no deductible will be applied to this claim*.
    *   `deductible_applied`: 0.00

2.  **Copay Amount:** I've reviewed the plan document. For inpatient admissions, there's no specific copay mentioned. The document notes that emergency room copays are waived if admitted and then become subject to deductible and coinsurance. Since no copay is stipulated for a direct inpatient admission, I'll assume it's $0.00.
    *   `copay_amount`: 0.00

3.  **Coinsurance Calculation:** The in-network coinsurance is 20%. The allowed amount for this claim is $18400.00. With the deductible applied being $0.00, the full allowed amount is subject to coinsurance. My initial calculation for the member's coinsurance responsibility would be 20% of $18400.00, which equals $3680.00.

4.  **OOPM Check:** This is where things get critical. The member's individual in-network OOPM is $6000.00. They have already accumulated $5400.00 towards this limit. This means they have $600.00 remaining before hitting their OOPM ($6000.00 - $5400.00).
    *   My calculated coinsurance responsibility of $3680.00 *exceeds* the remaining OOPM. Therefore, the member's coinsurance responsibility will be capped at the remaining OOPM amount.
    *   `coinsurance_amount`: 600.00

5.  **Total Member Responsibility:** Summing up the components for the member: $0.00 (deductible) + $0.00 (copay) + $600.00 (coinsurance) = $600.00.
    *   `member_responsibility`: 600.00

6.  **Plan Paid Amount:** This is calculated as the allowed amount minus the total member responsibility. $18400.00 - $600.00 = $17800.00.
    *   `plan_paid`: 17800.00

7.  **Ending Accumulators:**
    *   **Member Deductible:** Since no deductible was applied to this claim and the YTD credit was already at the full amount, the ending member deductible remains unchanged.
        *   `ending_member_deductible`: 1500.00
    *   **Member OOPM:** The $600.00 in coinsurance applied to this claim is credited towards the member's OOPM. Their YTD OOPM was $5400.00, so adding the $600.00 brings them exactly to their individual OOPM limit.
        *   `ending_member_oopm`: 6000.00

I've also considered the family OOPM ($12000.00 with $5400.00 YTD). Since the individual OOPM of $6000.00 is reached first with this claim, and the individual OOPM is embedded within the family OOPM structure, the individual limit takes precedence for this calculation.

Finally, I'll ensure all these values are presented in the correct numerical format, with exactly two decimal places. Everything appears to be in order.

**Adjudicating Claim 1: My Thought Process**

Alright, my task here is to meticulously adjudicate Claim 1, relying on the provided plan document and member accumulator data. The output needs to be a precisely formatted JSON object containing specific keys.

First, I'll break down the plan details relevant to this claim.
The individual INN deductible is $1500.00, and the individual INN Out-of-Pocket Maximum (OOPM) is $6000.00. Coinsurance for in-network services is a 20% member responsibility.

Now, I look at the member accumulators.
The member has already met their individual INN deductible, with $1500.00 credited year-to-date. This is crucial – it means no deductible will be applied to this claim.
For the OOPM, the member has $5400.00 credited year-to-date. This leaves a remaining OOPM of $600.00 ($6000.00 - $5400.00) for the individual INN. The family OOPM remaining is $6600.00 ($12000.00 - $5400.00), but the individual limit takes precedence here.

Next, I examine Claim 1 itself.
The service is an inpatient admission, processed in-network. The billed amount is $34960.00, but the allowed amount is $18400.00. This allowed amount is what I need to work with.
Regarding copays, the plan notes that the ER copay is waived if admitted, and the service then falls under standard deductible and coinsurance. There isn't a separate copay listed for inpatient admissions in this scenario. So, no copay applies here.

Since the individual INN deductible is met, the deductible applied is $0.00.
The allowed amount subject to coinsurance is $18400.00.
The member's coinsurance responsibility, at 20%, would normally be $3680.00 ($18400.00 * 0.20).
However, I must consider the remaining OOPM. The member has only $600.00 left towards their individual OOPM. Therefore, their coinsurance is capped at this remaining $600.00.
This means the coinsurance actually applied is $600.00.
The total member responsibility for this claim is therefore $600.00.
The plan's paid amount will be the allowed amount minus the member's responsibility: $18400.00 - $600.00 = $17800.00.
The copay amount is $0.00.

Now, I'll update the accumulators based on this claim.
The member's deductible remains at $1500.00 as it was already met.
The member's OOPM will increase by the coinsurance applied: $5400.00 + $600.00 = $6000.00. This brings the member to their individual OOPM limit for the year.

A quick double-check of the calculations confirms everything.
Deductible: Met, so $0.00 applied.
Coinsurance: 20% of $18400 = $3680.00, but capped by remaining OOPM.
OOPM limit: $600.00 remaining.
Copay: $0.00.
Member responsibility is indeed capped at $600.00.
Plan paid is $18400.00 - $600.00 = $17800.00.
Ending member deductible is $1500.00.
Ending member OOPM is $6000.00.

Finally, I need to ensure I populate the JSON object with the correct keys and values, adhering to the specified formatting (two decimal places, no quotes around numbers). The required keys are: `member_responsibility`, `plan_paid`, `deductible_applied`, `copay_amount`, `coinsurance_amount`, `ending_member_deductible`, and `ending_member_oopm`.

My finalized values for these keys are:
`member_responsibility`: 600.00
`plan_paid`: 17800.00
`deductible_applied`: 0.00
`copay_amount`: 0.00
`coinsurance_amount`: 600.00
`ending_member_deductible`: 1500.00
`ending_member_oopm`: 6000.00

Everything appears to be in order.

**My Thought Process on Claim Adjudication for Bluebonnet PPO 1500 (2026)**

Alright, let's break down this inpatient admission claim under the Bluebonnet PPO 1500 plan for 2026. My initial step is always to confirm the plan's structure and the member's current benefit utilization.

For an individual on this plan, the deductible is $1500 in-network (INN) and $3000 out-of-network (OON). The out-of-pocket maximum (OOPM) is $6000 INN and $12000 OON. I note that the deductible is *embedded*, which is crucial because it means individual limits are met independently before family limits come into play. The coinsurance for INN services, after the deductible is met, is a 20% member responsibility and 80% plan responsibility. A key detail is that copays *do not* apply to the deductible but *do* apply to the OOPM. For emergency room visits, there's a $400 copay, but this is waived if the visit results in an inpatient admission, in which case the inpatient deductible and coinsurance rules apply. This specific claim is an "Inpatient admission," not an ER visit *leading* to admission, so the ER copay rule isn't directly relevant here, other than reinforcing that inpatient is subject to deductible/coinsurance.

Before processing this current claim, I see the member has already satisfied $1500 towards their individual deductible and $5400 towards their individual OOPM. Since the deductible is embedded, their individual deductible of $1500 has been fully met. This also means their family deductible has been credited with $1500. Similarly, their individual OOPM has reached $5400.

Now, let's evaluate Claim 1:
*   **Date of Service:** 2026-05-14
*   **Service:** Inpatient admission
*   **Network:** In-network
*   **Allowed Amount:** $18,400.00

My first check is the deductible: The individual deductible is $1500, and it's already fully satisfied. Therefore, no deductible will be applied to this claim. ($0.00 deductible applied).

Next, I look at the OOPM. The individual INN OOPM is $6000. The member has already contributed $5400. This leaves $6000 - $5400 = $600 remaining to meet their individual OOPM.

The claim is for an inpatient admission, and it's in-network. Since the deductible is met, the coinsurance applies. The INN coinsurance is 20% for the member. So, 20% of the allowed amount ($18,400.00) is $18,400.00 * 0.20 = $3680.00.

However, the member's responsibility is capped by their remaining OOPM. The potential coinsurance of $3680.00 is greater than the remaining OOPM of $600.00. Therefore, the member's responsibility for this claim will be limited to that remaining OOPM amount: $600.00.

With the member's responsibility determined as $600.00, I can calculate what the plan pays. The plan pays the allowed amount minus the member's responsibility: $18,400.00 - $600.00 = $17,800.00.

So, the cost-share breakdown for this specific claim is:
*   **Deductible Applied:** $0.00 (as it was already met)
*   **Copay Amount:** $0.00 (no specific copay applies to this type of inpatient admission, and the ER copay is waived/replaced by coinsurance rules)
*   **Coinsurance Amount:** $600.00 (this is the amount that brings the member up to their OOPM limit)

After processing this claim:
*   The new individual deductible balance remains $1500.00 (since $0 was applied).
*   The new individual OOPM balance becomes $5400.00 (previous) + $600.00 (this claim) = $6000.00. The member has now reached their individual OOPM.

I've double-checked the specific phrasing about copays not crediting the deductible but crediting the OOPM. This is standard, and it confirms that coinsurance, which applies *after* the deductible, inherently credits towards the OOPM. There's no specific inpatient copay listed for this plan, so the default coinsurance rule is indeed the one to apply. The embedded nature of the deductible also means that once the individual hits $1500, that part of the benefit is satisfied for them, regardless of other family members.

The final figures for this claim are:
*   Member Responsibility: $600.00
*   Plan Paid: $17,800.00
*   Deductible Applied: $0.00
*   Copay Amount: $0.00
*   Coinsurance Amount: $600.00
*   Ending Member Deductible: $1500.00
*   Ending Member OOPM: $6000.00

The math appears sound, and all plan provisions seem to have been considered.

**My Thought Process on Adjudicating an Inpatient Admission under the Bluebonnet PPO 1500 Plan**

Alright, let's walk through this inpatient admission. I'm looking at the Bluebonnet PPO 1500 plan, a synthetic one, with a plan year running from January 1, 2026, to December 31, 2026. I need to figure out the member's responsibility and what the plan covers.

First, I've got the plan's structural details in mind:
*   Individual Deductible: $1500.00
*   Family Deductible: $3000.00 (embedded)
*   Individual Out-of-Pocket Maximum (OOPM): $6000.00
*   Coinsurance: 20% for the member, 80% for the plan.
*   Copays: Primary Care ($30), Specialist ($60), Urgent Care ($75), ER ($400 - waived if inpatient admission), Generic Retail Pharmacy ($15).
*   Crucially, copays do *not* apply towards the deductible, but they *do* count towards the OOPM.
*   Preventive care is fully covered by the plan.

Now, let's look at the member's current standing *before* this service:
*   Member Deductible: $1500.00 (already satisfied). This is important; it means the deductible won't be a factor in applying costs for this service.
*   Member OOPM: $5400.00 has been met. Their remaining OOPM is $6000.00 - $5400.00 = $600.00.
*   Family Deductible: $1500.00 (This is relevant for overall family cost tracking, but since the individual deductible is met, it doesn't change the individual's path here).
*   Family OOPM: $5400.00 (Similar to the family deductible, it's a tracking point but the individual's OOPM limit is the immediate constraint).

Now for the service itself:
*   Service: Inpatient admission.
*   Network Status: In-network.
*   Billed Charge: $34960.00.
*   Allowed Amount: $18400.00. This is the amount the plan allows for the service, and what we'll base calculations on.

My first thought is to determine how this service is handled. Is it a copay or coinsurance? I review the plan document. The listed copays are for specific services (PCP, Specialist, UC, ER, Pharmacy). Inpatient admission isn't listed with a specific copay. However, there's a key note in the ER copay section: "waived if the visit results in an inpatient admission, in which case the visit is subject to the deductible and coinsurance." This strongly indicates that inpatient admissions are subject to the deductible and coinsurance structure, not a flat copay. Since the member's deductible is already met, the deductible itself won't be applied.

So, I proceed with calculating the potential member responsibility based on coinsurance:
*   Allowed Amount: $18400.00.
*   Deductible applied: $0.00 (because it's already satisfied).
*   Coinsurance calculation: 20% of $18400.00 = $3680.00.

This $3680.00 is what the member *would* owe based purely on coinsurance after their deductible. However, I *must* consider their Out-of-Pocket Maximum.
*   Current OOPM met: $5400.00.
*   Remaining OOPM: $600.00.

The member's financial responsibility is capped by their remaining OOPM. Since the calculated coinsurance of $3680.00 is significantly higher than the remaining $600.00 OOPM, their responsibility will be limited to that $600.00.

Therefore, the Member Responsibility is $600.00.

Now, I can calculate what the plan pays:
*   Allowed Amount ($18400.00) - Member Responsibility ($600.00) = $17800.00.

Let's break down the member's responsibility for clarity:
*   Deductible portion: $0.00 (already met).
*   Copay portion: $0.00 (this service is subject to coinsurance).
*   Coinsurance portion: $600.00 (this is the amount that hit their OOPM limit).

Finally, I'll update the member's standing after this adjudication:
*   Ending Member Deductible: $1500.00 (no change, as it was already met).
*   Ending Member OOPM: $5400.00 (previous) + $600.00 (this service) = $6000.00. This means they have now reached their individual OOPM for the plan year.

So, to summarize the financial outcomes of this specific claim:
*   Member Responsibility: $600.00
*   Plan Paid: $17800.00
*   Deductible Applied: $0.00
*   Copay Amount: $0.00
*   Coinsurance Amount Applied to OOPM: $600.00
*   Ending Member Deductible: $1500.00
*   Ending Member OOPM: $6000.00

I've double-checked the math: $18400 * 0.20 = $3680$, which is indeed capped by the $600$ remaining OOPM. The logic flows correctly, and the final figures align with the plan rules and the member's status.

**Processing an Inpatient Claim under Bluebonnet PPO 1500 (2026 Plan Year)**

My current task involves analyzing an incoming claim for an inpatient admission under the Bluebonnet PPO 1500 plan for the 2026 plan year. I've got all the relevant plan details at hand: an individual in-network deductible of $1500.00 and an individual in-network Out-of-Pocket Maximum (OOPM) of $6000.00. For services after the deductible is met, the coinsurance structure is 20% for the member and 80% for the plan.

This specific claim, dated 2026-05-14, pertains to an in-network inpatient admission with an allowed amount of $18,400.00.

First, I need to address the deductible. I've already tracked that the member has met their full individual deductible of $1500.00. Therefore, no portion of this $18,400.00 allowed amount will be applied towards the deductible for this claim. The deductible applied will be $0.00.

Since the deductible has been met, coinsurance will apply to the allowed amount. My initial calculation for the member's coinsurance responsibility would be 20% of $18,400.00, which comes out to $3680.00.

Now, I must consider the Out-of-Pocket Maximum (OOPM). I know the member has already accumulated $5400.00 towards their $6000.00 OOPM for the year. This means they have $600.00 remaining before they hit their OOPM limit ($6000.00 - $5400.00 = $600.00).

Comparing the calculated coinsurance ($3680.00) to the remaining OOPM ($600.00), it's clear that the coinsurance amount exceeds the member's remaining OOPM limit. Therefore, the member's responsibility for this claim will be capped at the remaining OOPM amount, which is $600.00.

With the member's responsibility determined as $600.00, I can now calculate what the plan will pay. The plan's payment will be the allowed amount minus the member's responsibility: $18,400.00 - $600.00 = $17,800.00.

To break down the member's responsibility further:
*   Deductible applied: $0.00 (as it was already met).
*   Copay amount: $0.00 (inpatient services typically fall under deductible/coinsurance, not a flat copay unless it's a specific carve-out not indicated here).
*   Coinsurance amount: This is where the $600.00 comes into play. While the calculated coinsurance was $3680.00, the member only pays $600.00 of it because they've hit their OOPM. So, the coinsurance *contribution* to the member's responsibility is $600.00.

Finally, I'll update the accumulator values:
*   Ending Member Deductible: Remains at $1500.00, as no deductible was applied to this claim.
*   Ending Member OOPM: The previous $5400.00 plus the $600.00 responsibility from this claim brings the total to $6000.00, hitting the annual OOPM limit.

My final output confirms these figures: Member Responsibility: $600.00, Plan Paid: $17,800.00, Deductible Applied: $0.00, Copay Amount: $0.00, Coinsurance Amount: $600.00. The ending accumulators are correct: Ending Member Deductible: $1500.00 and Ending Member OOPM: $6000.00. I also ran a quick check to ensure the allowed amount equals plan paid plus member responsibility ($17,800.00 + $600.00 = $18,400.00) and that the member responsibility is correctly broken down ($0.00 + $0.00 + $600.00 = $600.00). All amounts are properly formatted to two decimal places, and the structure aligns with the expected JSON output.

We need answer exactly one fenced JSON code block no other. Need calculate benefit adjudication for Claim 1.

Let's parse task. Plan Bluebonnet PPO 1500. Member accumulators before Claim1: member deductible credited YTD 1500.00; member OOPM credited 5400.00; family deductible 1500; family OOPM 5400.

Claim1: 2026-05-14 Inpatient admission, in-network. Billed 34960, allowed 18400.

Need adjudicate. Plan deductible individual in-network 1500 embedded. Member deductible already met (1500 credited equals individual deductible). Family deductible 1500 credited but family threshold 3000; however embedded means individual can satisfy on own. Member has met individual deductible, so for this member deductible satisfied. Deductible applied on final claim = 0. No copay for inpatient admission listed. Coinsurance after deductible in-network 20% member / 80% plan. Member OOPM individual in-network 6000. Current OOPM 5400. Coinsurance amount = 20% of allowed 18400 = 3680.00. But OOPM remaining = 6000 - 5400 = 600. Once member reaches OOPM, plan pays 100% for remainder. Need apply member cost share up to OOPM. The claim allowed 18400 after deductible. Member coinsurance before OOPM would be 3680, but only 600 until OOPM. Member responsibility = 600 (all coinsurance? It is coinsurance portion capped by OOPM). Plan pays allowed - member resp = 17800. Need component fields: deductible_applied 0.00, copay_amount 0.00, coinsurance_amount? The coinsurance portion of final claim. Since member responsibility 600 is coinsurance (after deductible) limited by OOPM. So coinsurance_amount = 600.00, not 3680. Plan_paid=17800. member_responsibility=600. deductible_applied=0. ending_member_deductible=1500.00 (already met; no additional deductible; can accumulators exceed threshold? The deductible credited YTD remains 1500. Even though claim subject to coinsurance no deductible. In general once deductible met, accumulator stays at 1500, not add allowed amounts. Need ending_member_oopm = 5400 + 600 = 6000.00. Note family OOPM not asked. Check whether OOPM max is individual in-network 6000. Member OOPM credited YTD 5400. There is family OOPM 12000, embedded? Plan document says family OOPM but not explicit embedded for OOPM. It says once a member reaches OOPM plan pays 100%. It lists individual and family. In accumulator intro says OOPM ceiling on member cost share; once reached plan pays 100% for covered in-network services. For a member under family plan, if family OOPM reached maybe plan pays for all? Here family OOPM 5400 not near 12000. Individual member OOPM hits 6000. Good.

Need consider ER copay waived if inpatient admission? Not relevant, service is inpatient admission not ER. No copay for inpatient; subject to deductible/coinsurance. Good.

Need output JSON only fenced. Values numbers with two decimals? JSON numbers can be 600.00 but JSON numeric literal with trailing zeros is valid? JSON number syntax allows fraction with digits; 600.00 valid. It will parse as 600.0 but representation okay. Need include all required keys exactly. No extra keys. Ensure member_responsibility + plan_paid = 18400: 600 + 17800 = 18400. deductible_applied+copay+coinsurance = 600? It doesn't explicitly require but components should sum to member responsibility; yes.

Need round half up at end. 18400*0.2=3680 exact. cap 600 exact.

Potential nuance: Member deductible credited YTD = 1500 equals individual deductible. Family deductible credited =1500. Because structure embedded, an individual satisfies individual deductible on own; family deductible also satisfied once total family credits reach family amount, whichever comes first. The phrase "whichever comes first" could mean the individual deductible is satisfied when either individual credits reach 1500 OR family total reaches 3000? Actually embedded deductible: each member has individual deductible; family deductible can be met by combined credits. For this member, individual threshold met. No deductible.

Potential nuance: OOPM accumulators include copays and deductible and coinsurance. Starting OOPM 5400. Member deductible 1500 likely included in OOPM. Remaining OOPM 600. Apply to coinsurance. Good.

Need final only code block. Done.

Let me work through this.

Member accumulators before Claim 1:
- Member deductible credited YTD: 1500.00 (individual deductible is 1500.00, so deductible is satisfied)
- Member OOPM credited YTD: 5400.00 (individual OOPM is 6000.00, so 600.00 remaining)
- Family deductible: 1500.00
- Family OOPM: 5400.00

Claim 1: Inpatient admission, in-network, allowed 18400.00.

Deductible already satisfied (1500/1500). So no deductible applied.

Coinsurance: 20% member of allowed = 0.20 × 18400 = 3680.00.

But OOPM: member has 5400 credited, OOPM is 6000. Remaining OOPM room = 600.00. So member pays 600.00 coinsurance, then OOPM reached, plan pays the rest.

Member responsibility = 600.00. Plan paid = 18400 - 600 = 17800.00.

Copay: none for inpatient. Copay amount = 0.00.

Deductible applied = 0.00.

Coinsurance amount = 600.00 (the member's coinsurance portion actually paid).

Ending member deductible = 1500.00 (unchanged; copays don't credit deductible, and coinsurance doesn't credit deductible either — deductible credits come from deductible payments only). So 1500.00.

Ending member OOPM = 5400 + 600 = 6000.00.

Final answer fields:
- member_responsibility: 600.00
- plan_paid: 17800.00
- deductible_applied: 0.00
- copay_amount: 0.00
- coinsurance_amount: 600.00
- ending_member_deductible: 1500.00
- ending_member_oopm: 6000.00

Alright, let's break down this inpatient admission claim. My primary objective here is to determine the member's financial responsibility and the plan's payment for this specific service, ensuring it aligns with the Bluebonnet PPO 1500 plan benefits and the member's existing accumulators.

First, I need to establish the starting point. I'll look at the member's year-to-date (YTD) accumulators:
*   Their individual deductible YTD is $1500.00.
*   Their individual Out-of-Pocket Maximum (OOPM) YTD is $5400.00.
*   The family deductible YTD is also $1500.00.
*   The family OOPM YTD is $5400.00.

Next, I'll review the plan details for this member:
*   The plan is the Bluebonnet PPO 1500.
*   For an individual in-network, the deductible is $1500.00.
*   The individual in-network OOPM is $6000.00.
*   The coinsurance is set at 20% for the member and 80% for the plan.
*   Crucially, this is an inpatient admission. The plan document indicates it's subject to deductible and coinsurance, and there isn't a specific copay mentioned for this type of service, unlike some outpatient or ER visits.

Now, I'll process the claim itself:
*   It's for an inpatient admission on 2026-05-14, and it's an in-network service.
*   The allowed amount for this service is $18,400.00.

Let's walk through the adjudication steps:

1.  **Deductible:** The member's individual in-network deductible is $1500.00. Looking at their YTD accumulator, they've already met this ($1500.00). Therefore, *zero* dollars from this claim will go towards satisfying the deductible. `deductible_applied` = $0.00.

2.  **Coinsurance:** Since the deductible is satisfied, the claim is now subject to coinsurance. The member's coinsurance responsibility is 20% of the allowed amount. This is calculated on the full allowed amount because the deductible has already been met. So, the potential coinsurance is $18,400.00 * 0.20 = $3680.00.

3.  **Out-of-Pocket Maximum (OOPM):** The individual in-network OOPM is $6000.00. Before this claim, the member had already accumulated $5400.00 towards their OOPM. This means they have $6000.00 - $5400.00 = $600.00 of remaining "room" in their OOPM.
    Now, I compare the potential coinsurance ($3680.00) with the remaining OOPM room ($600.00). Since the potential coinsurance exceeds the OOPM room, the member's financial responsibility for this claim is capped at the remaining OOPM amount.
    Therefore, the `member_responsibility` for this specific claim will be $600.00.

    Let me clarify how this $600.00 breaks down:
    *   `deductible_applied`: $0.00 (as established).
    *   `copay_amount`: $0.00 (no copay for inpatient admission).
    *   `coinsurance_amount`: Since the OOPM capped the member's liability, the entire $600.00 that the member is responsible for *is* their coinsurance contribution. So, `coinsurance_amount` = $600.00.
    *   The total `member_responsibility` is $0.00 + $0.00 + $600.00 = $600.00, which correctly reflects the OOPM cap.

4.  **Plan Paid:** The plan will cover the remaining portion of the allowed amount. This is calculated as: `plan_paid` = Allowed Amount - Member Responsibility = $18,400.00 - $600.00 = $17,800.00.

Finally, I need to update the accumulators to reflect the situation *after* this claim is adjudicated. Since this is the only claim being processed, these will be the ending accumulators:
*   **Ending Member Deductible:** The initial deductible YTD was $1500.00, and $0.00 was applied from this claim. So, the `ending_member_deductible` is $1500.00.
*   **Ending Member OOPM:** The initial OOPM YTD was $5400.00, and the member's responsibility for this claim was $600.00. Therefore, the `ending_member_oopm` is $5400.00 + $600.00 = $6000.00. This signifies that the member has now met their individual out-of-pocket maximum for the year.

To summarize the required output fields:
*   `member_responsibility`: $600.00
*   `plan_paid`: $17,800.00
*   `deductible_applied`: $0.00
*   `copay_amount`: $0.00
*   `coinsurance_amount`: $600.00
*   `ending_member_deductible`: $1500.00
*   `ending_member_oopm`: $6000.00

Everything aligns logically. The member's cost share is entirely driven by the OOPM cap, and the coinsurance is the mechanism through which that OOPM cost is applied for this specific service. The plan picks up the rest, and the accumulators are updated to reflect the member reaching their OOPM.

Alright, let's break down this inpatient admission claim. My primary task here is to adjudicate a single claim for an inpatient admission, applying the member's benefit plan rules and their current accumulated year-to-date balances.

Here's my thought process for reaching the final adjudication:

First, I need to establish the member's starting point. This involves reviewing their existing accumulators before this claim is processed:
*   **Member Deductible YTD:** They've already met $1500.00 of their individual deductible.
*   **Member OOPM YTD:** They've already contributed $5400.00 towards their individual out-of-pocket maximum.
*   **Family Deductible YTD:** For family purposes, $1500.00 has been met.
*   **Family OOPM YTD:** Similarly, $5400.00 of the family OOPM has been met.

Next, I'll dive into the specifics of the plan document for the Bluebonnet PPO 1500 plan, focusing on the benefits relevant to this inpatient admission.
*   The service is an **in-network inpatient admission**.
*   The plan's **in-network individual deductible is $1500.00**.
*   The **in-network individual Out-of-Pocket Maximum (OOPM) is $6000.00**.
*   After the deductible is met, the plan structure dictates **20% coinsurance for the member and 80% for the plan**.
*   Crucially, the plan document doesn't specify a separate copay for inpatient admissions; it falls under the standard deductible and coinsurance framework.
*   An important detail: **Copays, if they existed for this service, would not apply towards the deductible, but they *would* count towards the OOPM**. However, since there's no copay, this point is moot for this specific adjudication.

Now, I'll analyze the claim itself, which is for an inpatient admission on 2026-05-14, with an allowed amount of $18,400.00.

The adjudication process begins:

1.  **Deductible Application:**
    *   The member's individual in-network deductible is $1500.00.
    *   Looking at their YTD accumulators, they have *already* met their $1500.00 deductible.
    *   Therefore, **no portion of this claim's allowed amount will be applied to the deductible**. The `deductible_applied` for this claim is $0.00.

2.  **Copay Assessment:**
    *   As established from the plan document, there is no specific copay for inpatient admissions.
    *   So, the `copay_amount` for this claim is $0.00.

3.  **Coinsurance Calculation:**
    *   Since the deductible is satisfied, coinsurance will apply to the full allowed amount.
    *   The member's coinsurance responsibility is 20%.
    *   The potential coinsurance amount would be 20% of $18,400.00, which is $3680.00.

4.  **Out-of-Pocket Maximum (OOPM) Consideration:**
    *   The individual in-network OOPM is $6000.00.
    *   The member has already accumulated $5400.00 towards this OOPM.
    *   This means they have $6000.00 - $5400.00 = $600.00 remaining before they reach their OOPM limit for the year.
    *   Now, I need to compare the calculated coinsurance ($3680.00) with the remaining OOPM amount ($600.00).
    *   The member's responsibility for this claim (the coinsurance) is capped at the remaining OOPM amount.
    *   Therefore, the member will only be responsible for $600.00 of the coinsurance. This is the `coinsurance_amount` that will be applied to this claim.
    *   Once this $600.00 is paid, the member will have successfully met their individual OOPM for the year ($5400.00 + $600.00 = $6000.00).

5.  **Finalizing Claim Amounts:**
    *   `deductible_applied`: $0.00 (as the deductible was already met)
    *   `copay_amount`: $0.00 (no copay for this service)
    *   `coinsurance_amount`: $600.00 (limited by the remaining OOPM)
    *   **Member Responsibility:** This is the sum of deductible applied, copay, and coinsurance: $0.00 + $0.00 + $600.00 = **$600.00**.
    *   **Plan Paid:** This is the allowed amount minus the member's responsibility: $18,400.00 - $600.00 = **$17,800.00**.
    *   I'll do a quick check: Member Responsibility ($600.00) + Plan Paid ($17,800.00) = $18,400.00, which matches the allowed amount. Everything is consistent.

6.  **Calculating Ending Accumulators:**
    *   **Ending Member Deductible:** Starting deductible ($1500.00) + Deductible applied from this claim ($0.00) = **$1500.00**. (The deductible remains met.)
    *   **Ending Member OOPM:** Starting OOPM ($5400.00) + Member responsibility applied to OOPM from this claim ($600.00) = **$6000.00**. (The member has now reached their OOPM.)

Based on this comprehensive analysis, the final adjudication details for this claim are established. I am confident in these figures and will now prepare the output.

Alright, let's break down this inpatient admission claim. My primary task here is to adjudicate this single claim and figure out exactly how much the member owes and how much the plan will cover, all while keeping track of their accumulated benefits.

My plan of action is to methodically go through several steps:

First, I need to get a clear picture of the member's financial status *before* this claim even hits. That means I'll be looking at their Year-to-Date (YTD) progress on their deductible and their Out-of-Pocket Maximum (OOPM). This gives me a baseline.

Next, I'll dive into the specifics of the claim itself. What kind of service is it? Is it in-network or out-of-network? And what's the total allowed amount for this service? This information is crucial for applying the right plan rules.

Then comes the core of the adjudication: applying the plan's rules. I'll be referencing the plan document to understand how inpatient admissions are treated. Specifically, I need to determine if a deductible applies, if there's a copay, and what the coinsurance responsibility is. The plan document mentions a copay rule that *can* apply to inpatient admissions if they stem from an ER visit, but this claim is stated as a direct inpatient admission, so I'll proceed with the standard deductible and coinsurance structure.

Once I know the plan rules, I'll calculate the member's cost-sharing obligations. This involves figuring out how much of their deductible still needs to be met, what any applicable copay would be, and then calculating the coinsurance on the remaining balance.

A critical part of this calculation is the OOPM. I need to see how much of the member's OOPM has already been met and how much is left. This acts as a ceiling for their total out-of-pocket expenses for the year. If my calculated cost-sharing exceeds the remaining OOPM, I'll cap the member's responsibility at that remaining OOPM amount.

After determining the member's responsibility for this specific claim, I'll then calculate the plan's payment by subtracting the member's responsibility from the allowed amount.

Finally, I'll update the member's YTD accumulators for both their deductible and OOPM based on the amounts applied from this claim. This ensures their benefit tracking is current for any future claims.

The end goal is to present all this information in a clear, structured output, typically a JSON object, detailing the member's responsibility, the plan's payment, and the updated accumulator values.

Let's walk through this with the provided numbers:

**Step 1: Understanding Where the Member Stands (Before Claim 1)**

*   Their individual deductible YTD is $1500.00.
*   Their individual OOPM YTD is $5400.00.
*   The family deductible and OOPM are the same, but since this is an individual claim, I'll focus on the individual accumulators.

**Plan Rules Snapshot:**

*   Individual in-network deductible: $1500.00
*   Individual in-network OOPM: $6000.00
*   Coinsurance (in-network, post-deductible): 20% for the member, 80% for the plan.
*   Inpatient admissions are subject to deductible and coinsurance. No specific copay for this type of admission as it's not linked to an ER visit.

**Step 2: Examining the Claim Details (Claim 1)**

*   Service: Inpatient admission, in-network.
*   Allowed Amount: $18400.00.

**Steps 3 & 4: Applying Rules and Calculating Cost Sharing**

*   **Deductible:** The member's individual deductible is $1500.00, and they've already met $1500.00 YTD. This means their deductible is *fully met*. So, no deductible will be applied to this claim.
    *   Deductible applied: $0.00
*   **Copay:** As noted, this isn't an ER-driven inpatient admission, so there's no copay associated with this service type.
    *   Copay amount: $0.00
*   **Coinsurance:** Since the deductible is met, coinsurance applies to the full allowed amount of $18400.00. The member's coinsurance rate is 20%.
    *   Potential member coinsurance: $18400.00 * 0.20 = $3680.00
*   **OOPM Check:** Now I need to see if this calculated coinsurance hits the OOPM limit.
    *   Member's individual OOPM limit: $6000.00
    *   Member's OOPM already met YTD: $5400.00
    *   Remaining OOPM "room": $6000.00 - $5400.00 = $600.00
    *   The potential member coinsurance ($3680.00) is much higher than the remaining OOPM room ($600.00). This means the member's responsibility will be capped by the remaining OOPM.
    *   Therefore, the actual member cost share for this claim is limited to **$600.00**.

*   **Breakdown of Member Cost Share for this Claim:**
    *   Deductible: $0.00
    *   Copay: $0.00
    *   Coinsurance: $600.00 (This is the amount that gets applied *before* hitting the OOPM limit. The remaining $3080.00 of potential coinsurance is absorbed by the OOPM reaching its cap.)

**Step 5: Determining Member and Plan Responsibility**

*   **Member Responsibility:** This is the total cost share applied to the member, which is our capped $600.00 (all of which is coinsurance in this scenario).
*   **Plan Paid:** This is the allowed amount minus the member's responsibility.
    *   Plan Paid: $18400.00 - $600.00 = **$17800.00**

**Step 6: Updating the Accumulators (After Claim 1)**

*   **Ending Member Deductible:**
    *   Starting Deductible: $1500.00
    *   Deductible Applied on this Claim: $0.00
    *   Ending Deductible: $1500.00 + $0.00 = **$1500.00** (Still met)
*   **Ending Member OOPM:**
    *   Starting OOPM: $5400.00
    *   Member Responsibility Applied to OOPM this Claim: $600.00 (which is the coinsurance amount applied)
    *   Ending OOPM: $5400.00 + $600.00 = **$6000.00** (The OOPM limit is now met)

**Step 7: Formatting the Output**

Based on these calculations, the final output for this claim would look like this:

*   `member_responsibility`: 600.00
*   `plan_paid`: 17800.00
*   `deductible_applied`: 0.00
*   `copay_amount`: 0.00
*   `coinsurance_amount`: 600.00
*   `ending_member_deductible`: 1500.00
*   `ending_member_oopm`: 6000.00

I've reviewed the logic, and it holds up. The member's deductible was already met, so no deductible applied. The service type meant no copay. The potential coinsurance was calculated, but then capped by the remaining OOPM. The plan covers the rest. The accumulators are updated correctly to reflect the member hitting their OOPM limit. Everything is in order.

Let me adjudicate Claim 1.

Member accumulators before Claim 1:
- Member deductible credited YTD: 1500.00 (individual deductible is 1500.00, so already met)
- Member OOPM credited YTD: 5400.00 (individual in-network OOPM is 6000.00)
- Family deductible credited YTD: 1500.00
- Family OOPM credited YTD: 5400.00

Claim 1 — 2026-05-14
- Inpatient admission, in-network
- Allowed amount: 18400.00

Since the member deductible is already met (1500.00 credited, individual deductible is 1500.00), no more deductible applies.

Coinsurance: 20% member / 80% plan
Member coinsurance: 18400.00 × 20% = 3680.00
Plan paid: 18400.00 × 80% = 14720.00

But wait, we need to check OOPM. Member OOPM before claim: 5400.00. Individual in-network OOPM: 6000.00.
Remaining before OOPM: 6000.00 - 5400.00 = 600.00

Member responsibility before hitting OOPM: 3680.00 (coinsurance, since deductible already met).
But only 600.00 of that counts toward OOPM before the OOPM is reached.

So:
- 600.00 of coinsurance is the member's responsibility, which brings OOPM to 6000.00.
- After OOPM is reached, plan pays 100% of the remaining allowed amount.
- Remaining allowed amount after the 600.00 member responsibility: 18400.00 - 600.00 = 17800.00

Wait, let me think more carefully. The allowed amount is 18400.00. No deductible applies (already met). Coinsurance would be 20% member = 3680.00. But OOPM limits member responsibility.

Member OOPM before claim: 5400.00
OOPM cap: 6000.00
Remaining OOPM capacity: 600.00

So the member pays 600.00 (which counts toward OOPM), bringing OOPM to 6000.00.
The plan pays the rest: 18400.00 - 600.00 = 17800.00

Let me verify: member_responsibility + plan_paid = 600.00 + 17800.00 = 18400.00 ✓

Now for the breakdown:
- deductible_applied: 0.00 (deductible already met)
- copay_amount: 0.00 (inpatient admission, no copay specified for this)
- coinsurance_amount: This is tricky. The coinsurance would be 3680.00, but OOPM caps it at 600.00. So the member's coinsurance responsibility is 600.00.
- member_responsibility: 600.00
- plan_paid: 17800.00

Ending accumulators:
- Member deductible: 1500.00 (no change, deductible already met)
- Member OOPM: 6000.00 (5400.00 + 600.00)

We need answer JSON only. Need adjudicate final claim (only one). Need parse plan. Need be careful. Member accumulators before claim: member deductible YTD 1500.00 = individual in-network deductible threshold 1500.00, so member deductible already satisfied? For in-network individual deductible 1500. Yes credited equals threshold. OOPM individual in-network 6000, member OOP 5400, so not yet OOP max, remaining 600. Family ded 1500 of 3000, family OOP 5400 of 12000. Claim inpatient admission in-network allowed 18400. Need apply deductible? Since deductible already satisfied (1500 credited) before claim, no deductible applied? But check embedded family deductible: individual deductible on their own; if individual satisfied, plan pays per individual? Yes. In-network services after individual deductible satisfied subject to coinsurance 20%. But OOPM: member out-of-pocket remaining to individual OOP max 6000 = 600. Once reached, plan pays 100% allowed for covered services. Claim1 member cost share should be at least? Coinsurance 20% of 18400 = 3680, but OOPM ceiling stops at 600 remaining. Need account copay? Inpatient admission no copay listed; subject to deductible and coinsurance (emergency room waived if inpatient admission, but this is inpatient admission). Deductible applied 0 (already met). Copay amount 0. Coinsurance amount? If not at OOPM, coinsurance 20% of allowed = 3680. But member OOP before 5400, individual OOP max 6000, remaining 600. Member responsibility capped at 600. How allocate between coinsurance_amount and plan_paid? Member responsibility 600, plan paid 17800. Deductible applied 0, copay 0, coinsurance amount? Could be 600 (capped coinsurance) because OOPM cap limits coinsurance. Plan paid = allowed - member resp = 17800. ending member deductible 1500.00 (unchanged), ending member OOP 6000.00. Need ensure family OOP? not asked. But family OOP max 12000, family OOP 5400+600=6000? Not asked.

But let's examine if there is any subtlety with aggregate vs embedded deductible? The plan: individual deductible 1500, family 3000 embedded. Member deductible YTD 1500.00 equals individual threshold; family deductible 1500 of 3000. For embedded, an individual can satisfy individual deductible on own; family deductible also satisfied once total family credits reach family amount, whichever comes first. Since member has 1500 individual satisfied, plan begins cost-sharing for this member. Deductible_applied for claim = 0 because no deductible remaining? But is deductible "balance" measured against individual threshold? Yes. In-network/out-of-network accumulate to single member deductible balance; threshold out-of-network is 3000. Since in-network, threshold 1500, balance 1500; satisfied. So no deductible applied.

But need maybe calculate plan paid and member responsibility with OOPM: Since member has OOP 5400, in-network individual OOP max 6000. Claim coinsurance 20% of allowed 18400 = 3680, but OOP max not reached before claim. Once a member reaches OOP maximum plan pays 100%. How exactly cap? Member pays coinsurance up to reaching OOPM; the remainder of allowed amount plan pays. Member responsibility = min(3680, 6000-5400) = 600. Plan paid = 18400 - 600 = 17800. Deductible 0, copay 0, coinsurance amount 600 (capped). Could some argue coinsurance amount is 3680, but member responsibility only 600 because plan pays extra? Usually coinsurance_amount field is member's coinsurance portion after cap, so 600. Need satisfy member_responsibility + plan_paid = allowed amount 18400. 600 +17800 =18400. Good.

Need output exactly JSON with required keys. Numeric two decimals. No extra text. Key names exact. Let's ensure no "copay_amount" 0.00, "deductible_applied" 0.00, "coinsurance_amount" 600.00, "ending_member_deductible" 1500.00, "ending_member_oopm" 6000.00. Member responsibility 600.00, plan paid 17800.00.

Let's think about if copays credit OOPM. Already 5400 maybe includes copays; no matter. Deductible applied 0 but OOPM applies. If deductible not applied, coinsurance is only cost share. But OOPM cap: the member responsibility 600 credits to OOPM; no deductible credits, so OOPM ending 6000. Deductible ending unchanged 1500.

Double-check family deductible: Family deductible credited YTD 1500.00 < 3000. Does embedded structure mean an individual must meet individual deductible before plan pays for that individual, which has happened. If family ded not met, no effect? Plan says "an individual satisfies the individual deductible on their own; family deductible also satisfied once total family credits reach family amount, whichever comes first." Actually "whichever comes first" maybe means if individual deductible satisfied, for that individual benefits begin; if family deductible (total family credits) reaches family amount before any individual? For embedded, individual satisfied at 1500, so plan pays for that member; family deductible not met. Good.

Could there be deductible applied even though accumulated threshold met but family deductible not met? No. The "single member deductible balance" is 1500. For in-network threshold 1500, met. Need not apply 1500 again. If family aggregate would require family 3000, but plan says embedded. Good.

Potential issue: OOPM individual in-network 6000. Member OOP credited 5400. Does deductible accumulator 1500 counts towards OOPM? It must; out-of-pocket max includes deductible and copays/coinsurance. Accumulator says OOP credited 5400, deductible credited 1500, so consistent. Remaining 600. Good.

But wait: the claim is inpatient admission, allowed amount 18400. If deductible already met, coinsurance 20% = 3680. However OOPM remaining 600. Member pays 600. Plan pays 17800. Plan paid > 80% due to OOP cap. Correct.

Need maybe report ending member deductible after all claims: 1500.00. If no deductible applied, same. If deductible had not been met, would be allowed amount deductible up to remaining. But no.

Could there be "deductible_applied" amount if claim amount applied to family deductible? Hmm, even if individual deductible met, should remaining allowed also credit family deductible? Deductible "credits" accumulate for family. But field asks deductible portion of claim—member's deductible cost share. Since individual met, member pays no deductible. But does the claim's allowed amount credit the family deductible without member paying? No, deductible credit is amount member pays at allowed rate before coinsurance. If no deductible cost share, no credit. Family deductible remains 1500. But if the plan were aggregate, maybe need pay 1500? But not.

Let's read plan: "Deductible: Individual (in-network) 1500; Family 3000; Structure EMBEDDED — an individual satisfies the individual deductible on their own; the family deductible is also satisfied once total family credits reach the family amount, whichever comes first." This means for an individual with 1500 credited, individual deductible is satisfied. Good.

No need mention rules. The task family doesn't ask rules. Required keys only. Use JSON block.

Need ensure no commentary before/after. Final exactly one fenced JSON block. They want "Reply with exactly one fenced JSON code block and nothing else." So final with ```json ... ```.

Let's ensure numbers: 17800.00 two decimals. Good.

But maybe plan_paid should be 14720? Let's see if OOP max ignored? If no OOP cap, member responsibility 3680, plan paid 14720, ending OOP 9080 > OOP max. But OOPM ceiling means once reached plan pays 100%. Member can't pay beyond. So 600 cap. Plan paid includes (80% coinsurance plan portion for part of claim before OOPM? Let's allocate: if member needs 600 to hit OOPM, plan pays remaining 17800. This includes plan coinsurance 80% of amount subject to coinsurance until OOP max, plus 100% after OOP. It is not simply 80% of 18400 = 14720; the OOP cap increases plan paid. Correct.

Potential nuance: OOPM is 6000 individual in-network. Member OOP "credited" 5400. But maybe family OOP max is 12000 and family OOP 5400, remaining? Individual OOPM has not been reached (5400 < 6000), so cap at 600. If family OOP max was 12000, remaining 6600; but individual OOPM can be reached before family? The plan says family OOPM 12000; but for PPO, individual OOP max embedded? It states "Once a member reaches the out-of-pocket maximum the plan pays 100%..." with individual 6000, family 12000. Usually embedded OOPM: individual need not exceed 6000 even if family not at 12000. It says "Individual (in-network) 6000; Family (in-network) 12000." Not explicitly "embedded" for OOPM but "Once a member reaches..." The accumulators include family. We should use member OOP 5400 toward individual 6000, cap 600. If aggregate family OOPM, remaining 6600, but likely individual OOP max caps. The wording "Once a member reaches the out-of-pocket maximum" and "Individual (in-network) 6000" means each member. So 600. Good.

Could member deductible YTD 1500 and OOP YTD 5400: if OOP includes deductible, remaining 600. If not? But glossary OOPM includes deductible. Yes.

Let's consider if an inpatient admission might be subject to deductible even if deductible already met? No, no additional.

Let's see if there is an in-network per-service copay for inpatient? Not listed. So just deductible/coinsurance.

Now final. Ensure JSON valid.

Let me work through Claim 1.

Starting accumulators:
- Member deductible credited: 1500.00
- Member OOPM credited: 5400.00
- Family deductible credited: 1500.00
- Family OOPM credited: 5400.00

Individual deductible (in-network) = 1500.00
Individual OOPM (in-network) = 6000.00

Member deductible is already satisfied at 1500.00.
Member OOPM is at 5400.00, which is below the 6000.00 individual OOPM.

Claim 1: Inpatient admission, in-network, allowed amount = 18400.00

Since deductible is already satisfied (1500.00 >= 1500.00), no deductible applies.
Coinsurance: 20% member / 80% plan
Member coinsurance = 18400.00 * 0.20 = 3680.00
Plan paid = 18400.00 * 0.80 = 14720.00

But wait, need to check OOPM. Current OOPM = 5400.00. Individual OOPM = 6000.00.
Remaining before OOPM = 6000.00 - 5400.00 = 600.00

Member coinsurance would be 3680.00, but only 600.00 of that counts before hitting OOPM.
Once OOPM is reached, plan pays 100%.

So member responsibility = 600.00 (the remaining amount to hit OOPM)
Plan paid = 18400.00 - 600.00 = 17800.00

Let me verify:
- Deductible applied: 0.00 (deductible already satisfied)
- Copay: 0.00 (no copay for inpatient)
- Coinsurance: would be 3680.00, but capped at 600.00 due to OOPM
- Member responsibility: 600.00
- Plan paid: 17800.00

Ending accumulators:
- Member deductible: 1500.00 (unchanged)
- Member OOPM: 5400.00 + 600.00 = 6000.00

member_responsibility + plan_paid = 600.00 + 17800.00 = 18400.00 ✓
