Introduction
CMS-0057-F sets January 1, 2027 as the deadline for payer FHIR APIs, with turnaround standards already in effect since 2026. The industry calls it the end of manual prior authorization, but coverage gaps, drug exclusions, and voluntary provider adoption tell a different story. This paper examines what the mandate actually requires and how organizations can turn payer compliance into provider advantage.
