Scores derived from CMS public data under the No Surprises Act (Pub. L. 116-260). Provider-side: IDR filing rates from CMS quarterly IDR data. Payer-side: MRF publication status from CMS non-compliant issuer list. Both are federal public domain (US-Government-Works).

Limitations: IDR filing data is aggregate and may not reflect individual dispute outcomes. MRF compliance is based on the CMS non-compliant issuer list; absence from the list does not guarantee full compliance. This index is a research tool, not a legal determination.
