This would be needed for some of the workflow options that businesses may decide to use. package_name: hl7.fhir.us.davinci derivation: constraint name: GFEServiceLinkingInfo type: Extension elements: extension: short: This could be the scheduled date(s) of a particular admission/service or a series of admissions/services. mustSupport: true array: true index: 0 slicing: slices: plannedPeriodOfService: match: {} schema: short: This could be the scheduled date(s) of a particular admission/service or a series of admissions/services. mustSupport: true array: true index: 0 extensions: {} elements: extension: {index: 1} url: pattern: {type: Uri, value: plannedPeriodOfService} index: 2 value: choices: [valueDate, valuePeriod] index: 4 valueDate: {type: date, choiceOf: value, index: 5} valuePeriod: {type: Period, choiceOf: value, index: 6} required: [valuePeriod, value, valueDate] linkingIdentifier: match: {} schema: short: An identifier assigned to a particular service or series of services, generally by a scheduling facility, to be used by all providers and practitioners who will be submitting a GFE for a patient's care. mustSupport: true array: true index: 7 extensions: {} elements: extension: {index: 8} url: pattern: {type: Uri, value: linkingIdentifier} index: 9 value: choices: [valueString] index: 11 valueString: {type: string, choiceOf: value, index: 12} required: [valueString, value] url: pattern: {type: Uri, value: 'http://hl7.org/fhir/us/davinci-pct/StructureDefinition/gfeServiceLinkingInfo'} index: 13 value: choices: [] index: 15 package_version: pct-1.1.0 extensions: plannedPeriodOfService: url: null short: This could be the scheduled date(s) of a particular admission/service or a series of admissions/services. mustSupport: true array: true index: 0 extensions: {} elements: extension: {index: 1} url: pattern: {type: Uri, value: plannedPeriodOfService} index: 2 value: choices: [valueDate, valuePeriod] index: 4 valueDate: {type: date, choiceOf: value, index: 5} valuePeriod: {type: Period, choiceOf: value, index: 6} required: [valuePeriod, value, valueDate] linkingIdentifier: url: null short: An identifier assigned to a particular service or series of services, generally by a scheduling facility, to be used by all providers and practitioners who will be submitting a GFE for a patient's care. mustSupport: true array: true index: 7 extensions: {} elements: extension: {index: 8} url: pattern: {type: Uri, value: linkingIdentifier} index: 9 value: choices: [valueString] index: 11 valueString: {type: string, choiceOf: value, index: 12} required: [valueString, value] class: extension kind: complex-type url: http://hl7.org/fhir/us/davinci-pct/StructureDefinition/gfeServiceLinkingInfo base: http://hl7.org/fhir/StructureDefinition/Extension version: 1.1.0
