FHIR Resources
Comprehensive guides to Fast Healthcare Interoperability Resources (FHIR)
FHIR Terminology
FHIR's terminology infrastructure: CodeSystem, ValueSet, and ConceptMap resources; the four terminology operations; binding strength; and implementation patterns for coded data.
CoverageEligibilityRequest and CoverageEligibilityResponse
Reference for the FHIR CoverageEligibilityRequest and CoverageEligibilityResponse resources: purpose codes, benefit discovery, authorizationRequired flag, X12 270/271 mapping, and when to use eligibility vs prior authorization.
What is FHIR
The FHIR model explained for integrators — resources, RESTful operations, references, profiles, extensions, and which version to target.
Claim and ClaimResponse
Reference for the FHIR Claim and ClaimResponse resources: the use field semantics, key structural elements, Da Vinci PAS profiles for prior authorization, X12 278 relationship, and the Claim vs EOB distinction.
FHIR Search
How FHIR search works: parameter types, modifiers, prefixes, includes, sorting, pagination, and performance patterns for querying resources at scale.
FHIR Extensions
Reference for how FHIR extensions work, when to use them, and how to design and govern extensions without breaking interoperability.
Patient
Reference for the FHIR Patient resource: demographics, identifiers, administrative status, and implementation considerations for identity and matching.
FHIR Profiling
Reference for FHIR conformance: profiles, extensions, terminology bindings, slicing, and how Implementation Guides define interoperable contracts.
FHIR References
How FHIR resources link to each other: relative, absolute, logical, and contained reference patterns, resolution rules, referential integrity, and search implications.
Observation
Reference for the FHIR Observation resource: category codes, value types, component vs hasMember, US Core profiles, and implementation pitfalls for labs, vitals, and clinical findings.
SMART on FHIR
SMART on FHIR authorization: EHR and standalone launch flows, scopes, PKCE, token handling, backend services, and common implementation failure modes.
