Method and limits
- Reporting lag: the CMS public-use file for a plan year reports claims from two plan years earlier (the PY2026 file carries 2024 claims). These are not this year's figures.
- In-network only: the denial rate is in-network claims denied divided by in-network claims received. Out-of-network claims are shown separately where the issuer reported them.
- "Denied" is broad: CMS counts every denial, including administrative denials, duplicate submissions, ineligibility, incorrect billing and partial denials, not only medical-necessity decisions.
- Issuer level: CMS reports the counts once per issuer per state and repeats them on every plan row; plan-level counts, where present, list denials only, so no per-plan rate is computed.
- Coverage: only issuers on the federally facilitated marketplace (HealthCare.gov states) report to this file. Employer plans, Medicare and Medicaid are not included.
- No inference of intent: a higher rate can reflect the issuer's mix of claims, its billing rules or its membership as much as its coverage decisions. Compare with the state median and read the N.
- Issuer filings are mapped to Anthem / BlueCross BlueShield by the issuer's legal name (conservative brand matching); a filing that is not obviously BCBS's is left out rather than guessed.
