Cerner FHIR API
Provides FHIR R4 REST API access to clinical data stored in Oracle Health (Cerner) EHR systems across 750+ healthcare organizations.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HIPAA-compliant, SMART on FHIR OAuth 2.0 with fine-grained clinical scopes (e.g., patient/Condition.read), TLS required on all endpoints, BAA required for PHI access
⚡ Reliability
Best When
Building patient-facing or clinician-facing apps that need structured clinical data (conditions, meds, labs, vitals) from Cerner-hosted health systems, especially when targeting the 750+ Cerner sites.
Avoid When
You need non-FHIR data, your target health systems don't use Cerner, or you need real-time autonomous agent access (SMART on FHIR OAuth flow is not agent-friendly).
Use Cases
- • Patient portal and consumer health apps via SMART on FHIR
- • Clinical decision support tools integrated with EHR workflows
- • Population health analytics pulling structured clinical data
- • Care coordination apps reading patient conditions, medications, and observations
- • Appointment scheduling and management integrations
Not For
- • Direct billing or claims submission (use separate revenue cycle APIs)
- • Non-FHIR data formats — output is strictly FHIR R4 resources
- • Organizations whose patients are not on Cerner EHRs
Interface
Authentication
SMART on FHIR OAuth 2.0 required. Separate flows for patient-facing (patient/$launch) and provider-facing (provider/$launch) apps. Sandbox uses mock OAuth. Production requires approved app registration and HIPAA BAA with the specific health system.
Pricing
Developers register free on code.cerner.com. Production access requires approval from each health system and a HIPAA BAA.
Agent Metadata
Known Gotchas
- ⚠ SMART on FHIR OAuth requires user-facing browser redirect — not compatible with autonomous agents
- ⚠ Each health system is a separate authorization endpoint; no unified access layer
- ⚠ HIPAA BAA must be signed with every health system before accessing production PHI
- ⚠ Sandbox data is synthetic; production behavior may differ per-org customization
- ⚠ Rate limits vary per health system and are not publicly documented
