description: Entity graph for the Elevance Health FHIR estate, derived from the resource and searchParam
  declarations in the live CapabilityStatements rather than from prose. Every entity below is a standard
  HL7 FHIR R4 resource, so its full field-level schema is the FHIR StructureDefinition at hl7.org/fhir/R4/<resource>.html;
  what is provider-specific is WHICH resources Elevance exposes, which interactions it allows on each,
  and which reference edges it lets you traverse. Relationship targets are inferred from FHIR search-parameter
  naming where the capability statement does not name a target type, and are marked where uncertain.
model: HL7 FHIR R4 (4.0.1)
id_scheme:
  style: FHIR logical id
  detail: Opaque server-assigned string in Resource.id; references take the form <ResourceType>/<id>.
    No human-readable prefixes.
schema_reference: https://hl7.org/fhir/R4/resourcelist.html
custom_extensions:
  file: conformance/elevance-health-fhir-extensions.json
  detail: Elevance publishes its own FHIR extensions for 29 resource types; that document is the authoritative
    list of the non-standard fields on these resources.

notes:
- Basic is the FHIR resource Da Vinci uses to carry a FormularyItem; MedicationKnowledge carries a FormularyDrug.
- Patient.$everything is the only instance-level operation exposed, and it is the closest thing to a bulk
  read on this estate. No $export is declared.
- Every entity on every CMS surface is read-only. The write surface in this estate is the legacy Patient360
  DSTU2 server, whose resource set is documented in conformance/elevance-health-patient360-dstu2-conformance.xml.
