Cerner Millennium FHIR R4

What it is

Cerner Millennium (now Oracle Health) is the second-largest EHR platform in US health systems. Its FHIR R4 API exposes the same standard resource types as Epic (Patient, Encounter, Condition, MedicationRequest, Observation, DocumentReference, Procedure) via SMART on FHIR backend service auth. Agents use it as the Cerner-deployment equivalent of the Epic FHIR skill, providing the same clinical context to downstream workflows.

When to use this skill

• Read active diagnoses, medications, and allergy lists from a Cerner-hosted chart
• Retrieve encounter context (class, service, attending NPI) for routing and documentation
• Fetch clinical notes or discharge summaries (DocumentReference) for coding or CDI workflows
• Access procedure records and lab observations for quality measurement
• Create draft documentation or orders in the Cerner PowerChart note workflow (write scope)
