Curated cohort / fixed public roster
Louisiana marketplace issuer cohort
The Patient Access and Provider Directory APIs of every issuer selling an individual-market qualified health plan on HealthCare.gov in Louisiana for 2026, graded on the same public surfaces as every other endpoint here.

5 of 6 member organizations publish a FHIR base URL this project could verify from public documentation, which is a curation record with a date on it, not a live figure; 6 verified endpoints are listed below. Of those, 3 answered when this page was generated, which is the measured number: it comes from this run's probes, and it moves when the endpoints do. The rest of the roster is recorded with the reason it could not be listed, because for a cohort whose membership is public and finite, the gap is itself a finding.
Membership is CMS's own file, not a list assembled here. Filtered to Louisiana, the QHP Landscape PY2026 Individual Medical dataset carries 2,218 plan-county rows, 6 HIOS issuer IDs, and 6 issuer names. The roster was frozen before any URL was probed and is committed beside this file as louisiana-marketplace.roster.csv.
Every member either points at registry endpoints or carries an exclusion with a dated review record and the source that was read. An exclusion is a statement about what this project could find on the date it looked, never a statement about whether an issuer meets an obligation.
Several members point at endpoints already in the registry. Where a carrier publishes one national surface, the same entry is cited from more than one cohort rather than duplicated, because listing one address under several names would misstate how many endpoints exist.

Grades are comparable within a category only: a Patient Access API and a Provider Directory API answer to different expectations and are never ranked against each other.
What "did not answer" was
The condition each listed endpoint that did not answer was observed in on this run, kept apart by category and never added together. An endpoint that answered and declined this request is running; an endpoint that produced no document is a different fact about a different thing. This project reports the condition and reads neither of them as a choice or as a defect.
| Endpoint | Condition | What it means |
|---|---|---|
| AmeriHealth Caritas Next Louisiana Patient Access API | No answer reached this project | no answer from the surface reached this project |
| Endpoint | Condition | What it means |
|---|---|---|
| Centene Provider Directory API (Ambetter) | Answered, and declined this request | the surface answered, and declined to serve this request |
| CHRISTUS Health Plan Provider Directory API | Answered, but not with the document | the surface answered, and the answer was not the document |
What the listed endpoints declare
How many of the listed endpoints with a readable CapabilityStatement declare each resource and each interaction on it, counted within a category and never across one. Declared, not tested.

Members reviewed and not listed
Each exclusion records how far the review went, on what date, and where to check it. A review that found nothing is not proof that nothing exists: if one of these plans publishes a base URL we missed, please tell us.
| Plan | Programs | Why it is not listed |
|---|---|---|
| HMO Louisiana | Louisiana individual marketplace (HealthCare.gov) | the parent publishes base URLs but scopes them in its own words to its own coverages, and names this subsidiary on that page only in boilerplate; nothing published by either entity names HMO Louisiana in connection with a FHIR API (the plan's own documentation was reviewed, 2026-09-04; source) |
Observational snapshots of public discovery surfaces. Not audits, not compliance determinations, and not statements about care quality. Publishing a base URL to unregistered visitors is not required by any rule this project reads, and a plan that does not is not violating anything; it is only not independently checkable from outside.
