The CMS Interoperability and Prior Authorization final rule (CMS-0057-F) requires CMS-regulated payers to implement FHIR-based APIs across six categories by January 1, 2027. This compliance suite provides an interactive sandbox for testing all required API endpoints, including Prior Authorization Support (PAS), Patient Access, Provider Access, Payer-to-Payer data exchange, Coverage Requirements Discovery (CRD), and Documentation Templates and Rules (DTR). Together these APIs form the electronic prior authorization (ePA) ecosystem mandated by ONC and supported by AHIP industry commitments.
