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: Says the machine-readable files "will be refreshed monthly." The landing page names no posting day within the month and states no schedule beyond monthly refreshment.4
Index shape: Presents the machine-readable files under eight named regional sections — California – Northern, California – Southern, Colorado, Georgia, Hawaii, Mid-Atlantic States, Northwest and Washington — and states that within a given region some plans with an in-network-rate file may have no associated table-of-contents file.4
Back catalogue: States no retention period for prior months. As of August 7, 2026, the table-of-contents files named in Kaiser's own monthly file lists resolved in full for the May, June, July and August 2026 lists (22 of 22 named paths each). The April 2026 list resolved for 20 of its 22 named paths, the two Washington entries excepted. For the March 2026 list and earlier, the dated regional table-of-contents paths no longer resolved, apart from the two Colorado state-mandated entries those lists carry, which are dated January 1, 2026 and did still resolve. That is an observation on a single date, not a published commitment.4 5

[1] Fast Facts · Kaiser Permanente · checked 2026-08-06
Fetched 2026-08-06. Kaiser's own fact-sheet page; carries no explicit publication date, so publishedDate is set to the payer's stated 'Data as of March 31, 2026, unless otherwise noted.' Page names nine regions (Northern California, Southern California, Colorado, Georgia, Hawaii, Mid-Atlantic States, Nevada, Northwest, Washington) but states no numeric state count.
[2] 37 Kaiser Permanente hospitals recognized by U.S. News & World Report · Kaiser Permanente · checked 2026-08-06
Fetched 2026-08-06; headline and August 4, 2026 publication date read off the page itself, not inferred from the URL slug. Cited only for the standing "About Kaiser Permanente" boilerplate, which reads "We currently serve 12.9 million members in 9 states and the District of Columbia." — the most recent release carrying that sentence, superseding the 2026-07-01 Northern Nevada medical offices release. Kaiser says "currently" with no stated as-of, so the publication date is the as-of proxy.
[3] Kaiser Permanente and Risant Health Report 2025 Financial Results · Kaiser Permanente · checked 2026-08-06
Fetched 2026-08-06. Corroborates the annual report revenue: 'KFHP/H & Risant Health combined operating revenues for 2025 were $127.7 billion compared to $115.8 billion in 2024.' Its boilerplate still read '12.6 million members in 9 states and the District of Columbia'. Cited in preference to the annual-report PDF because that sentence is contiguous prose; the PDF's equivalent is split across infographic layout elements.
[4] Transparency in Coverage Health Plan Machine-Readable Files · Kaiser Foundation Health Plan, Inc. (Kaiser Permanente) · checked 2026-08-07
Fetched 2026-08-07. Kaiser's Transparency in Coverage page. Every region prefix renders the same copy and each declares itself canonical to its own region URL, so the region actually opened is the one cited, and this record is the Northern California one. The file listings are built in the browser; the prose both Kaiser claims rest on is in the page itself. Nothing on it states a posting day, a retention period or an archive, and no publication date is printed, so publishedDate is omitted.
[5] Kaiser Permanente monthly machine-readable file list (in-network), August 2026 · Kaiser Foundation Health Plan, Inc. (Kaiser Permanente) · checked 2026-08-07
Fetched 2026-08-07. A plain-text manifest of the regional table-of-contents paths Kaiser names for that month; every line is a path and a byte count, and the document is neither a table of contents nor a rate file. It is not a hyperlink on the landing page — the URL is assembled at runtime by the page's transparency script — and a manifest is published per month at this same URL shape with the month substituted.
