Summary of the Rule or Edit Change

The Departments of Health and Human Services, Labor and the Treasury published the Transparency in Coverage final rules in the Federal Register on October 6, 2026 (CMS-9882-F). They amend the price transparency reporting requirements for non-grandfathered group health plans and for insurers that offer non-grandfathered group or individual coverage. The rules take effect December 7, 2026, 60 days after publication, with several requirements phased in later.

Plans and insurers already have to post machine-readable files with their negotiated rates and out-of-network allowed amounts. The final rules change how those files are built and how often they're posted. File updates move from monthly to quarterly, which CMS says will save about $174.5 million a year starting in the second year. The out-of-network allowed amount threshold drops from 20 claims to 11, and allowed amounts are aggregated by insurance market type. Plans have to exclude provider and rate combinations that are unlikely to be paid based on the provider's specialty, and a senior official has to attest that the files are complete to the best of their knowledge.

The phase-in is staggered. The in-network and out-of-network amendments apply 5 months after publication, which puts them in early March 2027. Three new files (a taxonomy mapping file, a file of claims volume data and a plain text locator file) apply 11 months after publication. Updates to the internet-based self-service tool apply to plan years beginning on or after January 1, 2027. Plans also have to post a "Price Transparency" link in the website footer and use a single JSON format for the files.
