MEDITECH Expanse FHIR API
MEDITECH's FHIR API surface for Expanse, exposed to approved developers through the Greenfield Workspace. US Core FHIR R4 provides view-only access to patient-facing data after the patient authorizes the requesting app (USCDI v1, DSTU2/R4 compatible, patient workflows only). Separate FHIR Scheduling APIs support user and patient workflows for Expanse customers. Service base URLs are issued per customer facility.
