Referral Profile¶
| Canonical | ../StructureDefinition/nexus-core-referral |

| Status | draft · 1.26.0 |
| Base | ServiceRequest (constraint) |
| Source | FSH · JSON |
Defines the Nexus EMR FHIR profile for referrals: a request that another clinician or service accept the patient, for consultation, second opinion, or ongoing management. Aligned to the pan-Canadian CA-eReC / Ontario eReferral contract, which is the shape Nexus already exchanges with Ocean. Distinct from NexusEmrCoreServiceRequest, which governs laboratory, imaging and procedure ORDERS and fixes intent to order.
