BaseServiceRequest (constraint)
SourceFSH · 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.
