It is based on the [CommunicationRequest](https://hl7.org/fhir/R4/communicationrequest.html) resource and identifies the additional constraints, extensions, vocabularies and value sets that **SHALL** be present in the CommunicationRequest when conforming to this profile. package_name: hl7.fhir.au.ereq derivation: constraint name: AUeRequestingCommunicationRequest abstract: true type: CommunicationRequest elements: category: binding: {strength: extensible, valueSet: 'http://terminology.hl7.org.au/ValueSet/au-erequesting-communicationrequest-category'} mustSupport: true index: 3 recipient: type: Reference mustSupport: true refers: ['http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-patient', 'http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-practitionerrole'] index: 8 authoredOn: {mustSupport: true, index: 6} requester: type: Reference short: Provider, Patient, or Organisation requesting the communication mustSupport: true refers: ['http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-organization', 'http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-patient', 'http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-practitionerrole'] index: 7 status: pattern: {type: Code, value: active} mustSupport: true index: 2 groupIdentifier: type: Identifier mustSupport: true index: 0 elements: type: pattern: type: CodeableConcept value: coding: - {code: PGN, system: 'http://terminology.hl7.org/CodeSystem/v2-0203'} index: 1 sender: type: Reference short: Organisation sending the communication mustSupport: true refers: ['http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-organization'] index: 9 subject: type: Reference short: Patient that is the subject of the communication request mustSupport: true refers: ['http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-patient'] index: 4 about: type: Reference mustSupport: true refers: ['http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-servicerequest-imag', 'http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-servicerequest-path'] index: 5 package_version: 1.0.0-preview class: profile kind: resource url: http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest base: http://hl7.org/fhir/StructureDefinition/CommunicationRequest version: 1.0.0-preview required: [authoredOn, requester, recipient, about, groupIdentifier, subject, category]
