Fonteum Research · No Surprises Act

NSA Compliance Leaderboard

Quarterly compliance scores derived from CMS IDR filing data (provider-side) and the CMS MRF non-compliant issuer list (payer-side). All data is federal public domain.

First issuance pending — the quarterly cron runs on the 15th of March, June, September, and December.

Operator can trigger manually via the Inngest dashboard (function: nsa-compliance-quarterly).

Methodology

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.
