Transparency in Coverage publishing

What this payer publishes under the Transparency in Coverage rule, how the published index is arranged, and what becomes of earlier months. Each statement is read from a public document and cites it.

Posting cadence
States that the machine-readable files are updated on a monthly basis, and that pricing information may change between a file's publication and the next monthly update. Names no specific calendar day for the refresh.3
Index shape
Publishes one landing page linking twelve table-of-contents index files: one each for Ambetter, Fidelis, QualChoice, Health Net and WellCare of North Carolina, plus seven QualChoice sub-indexes covering named employer groups. All twelve carried a single reporting entity in August 2026, Centene Management Company LLC, typed as a Third Party Administrator. Plans are identified by employer EIN in eight of the twelve indexes — the Health Net index, which also carries one HIOS-identified entry, and all seven QualChoice employer sub-indexes — and by HIOS identifier in the remaining four.34
Back catalogue
Publishes no stated retention period for superseded files. Index files dated from June 29, 2023 onward were observed on August 7, 2026 to remain reachable at their original date-stamped URLs, while index filenames dated June 1, 2023 and earlier were observed to return HTTP 404 at equivalent URLs in the same directory — indicating a bounded back catalogue rather than an open-ended one.35

    Fetched 2026-08-06 from EDGAR (accession 0001071739-26-000153). Most recent periodic filing as of the research date; used for the current membership figure. Membership table appears in Item 2 MD&A under the heading MEMBERSHIP.

    Fetched 2026-08-06 from EDGAR (CIK 0001071739, accession 0001071739-26-000049) with a declared User-Agent; SEC blocks default fetchers with HTTP 403. Figures read from Item 1 Business, Item 7 MD&A (Membership and Results of Operations) and the audited Consolidated Statements of Operations.

  3. [3] Transparency in Coverage Machine Readable Files · Centene Corporation · checked 2026-08-07

    Fetched 2026-08-07. Centene's Transparency in Coverage page, server-rendered and needing no JavaScript. It carries both the monthly-update sentence and the table-of-contents sentence naming the brands, and prints no publication or last-updated date, so publishedDate is omitted. A separate "Centene Employees" block further down the page links Cigna, Highmark, HMSA, Health Net and Anthem: those are the carriers for Centene's own employee benefit plans, Centene as an employer rather than as an issuer.

  4. [4] Centene table-of-contents index files (Ambetter, Fidelis, QualChoice and seven employer sub-indexes, Health Net, WellCare of North Carolina) · Centene Management Company LLC (published at centene.com by Centene Corporation) · checked 2026-08-07

    Fetched 2026-08-07. Table-of-contents metadata rather than rate files. The twelve index files the landing page links share five top-level keys at schema version 2.0.0, and each names reporting entity "Centene Management Company LLC", typed "Third Party Administrator". Filename date and internal last_updated_on agree on all of them except the Ambetter file, whose name reads 2026-07-27 where the field reads 2026-07-28; publishedDate follows the internal value.

  5. [5] Centene superseded table-of-contents index files at their original date-stamped URLs · Centene Management Company LLC (published at centene.com by Centene Corporation) · checked 2026-08-07

    Fetched 2026-08-07. The oldest superseded Centene index file that still resolves at its original date-stamped URL, cited for the reachability half of the back-catalogue claim. Older filenames in the same directory return HTTP 404, and the origin is not a catch-all, so a URL that resolves is evidence of retention rather than of a permissive server. Historical MHN index files still resolve although the live landing page links no MHN file, so the back catalogue reaches a brand the current page no longer offers.
