Use Case
FHIR R4 API Integration
The Problem
The Challenge
Federal mandates require FHIR R4 API access for patient data, but implementing production-grade FHIR APIs involves terminology mapping, consent management, and performance optimization that go beyond the specification. Meeting the FHIR specification is table stakes — the real challenge is building APIs that perform at scale, enforce patient consent correctly, handle terminology translation between systems, and support the Da Vinci implementation guides that payers and providers need for real-world interoperability.
Our Approach
How Selah Approaches This
We implement FHIR R4 APIs that are production-ready — with proper terminology binding, patient consent enforcement, rate limiting, and monitoring. Our implementations meet USCDI v4 requirements and support Da Vinci implementation guides for coverage requirements discovery (CRD), documentation templates and rules (DTR), and prior authorization support (PAS). SMART on FHIR provides the authorization layer.
Technology
The Architecture
The FHIR R4 server provides the API layer, with SMART on FHIR handling authorization and access control. A dedicated terminology service manages SNOMED CT, LOINC, and RxNorm mapping and validation. Patient consent management enforces data sharing preferences at the API level. Da Vinci implementation guides enable payer-provider interoperability workflows.
