The Importance of FHIR Compliance: Challenges and Requirements for Digital Healthcare in the USA
Keeping Up with FHIR Compliance for Transformative Digital Health Care
Summary
Due to CMS-0057 regulations, FHIR compliance has become a mandatory requirement for EHR vendors and health plans in the US. This rule mandates specific implementations across four key APIs: Patient Access, Provider Access, Payer-to-Payer data exchange, and Prior Authorization.
Details
The CMS-0057 regulation elevated FHIR compliance from a technical aspiration to a mandatory business requirement for EHR vendors and health plans in the US. The rule specifies requirements across four major FHIR APIs: Patient Access (requiring support for Patient, Coverage, etc.), Provider Access (for point-of-care data sharing), Payer-to-Payer API (for cross-payer member data exchange), and Prior Authorization API. The Prior Authorization API is noted as the most complex, requiring specific use of Da Vinci PAS IG and CRD IG. Technical implementation challenges include supporting SMART v2 scopes, adding incremental data export (_since handling), explicitly pinning ValueSet versions, and tuning rate limits for SMART apps. Meeting these requirements demands rigorous validation using FHIR conformance testing tools like Inferno. The text emphasizes that compliance must be treated as a substantial engineering project, not merely a feature checklist item, to ensure successful deployment and adherence to the standards.
