CMS-0057 & Policy
Patient Access API
Draft — pending verification
This reference entry has not yet been verified against its authoritative source (Original definitions; regulatory facts to be verified against CMS-0057-F (89 FR 8758) and X12/HL7 documentation). Do not rely on it for production configuration until this notice is removed.
In more depth
CMS-0057-F also added annual reporting of Patient Access API usage metrics to CMS beginning in 2026. For PA teams the interesting part is the data obligation: authorization status must be accurate and member-comprehensible on an API surface, which quietly forces internal authorization-data cleanup.
