description: Defines a computable value set as one that SHALL have an expression-based definition (i.e. a value set defined intensionally using expressions of the code systems involved) and MAY have an expansion included. The expression-based definition SHALL be represented in only one of three ways; using the compose element, using the expression extension, or using the rules-text extension to provide a step-by-step process for expanding the value set definition package_name: hl7.fhir.us.cqfmeasures derivation: constraint name: CQFMComputableValueSet type: ValueSet elements: extension: short: Human instructions for constructing the valueset type: Extension mustSupport: true url: http://hl7.org/fhir/StructureDefinition/valueset-rules-text index: 0 slicing: slices: rulesText: match: {} schema: {short: Human instructions for constructing the valueset, type: Extension, mustSupport: true, url: 'http://hl7.org/fhir/StructureDefinition/valueset-rules-text', index: 0} min: 0 max: 1 expression: match: {} schema: {short: Machine instructions for constructing the value set, type: Extension, mustSupport: true, url: 'http://hl7.org/fhir/StructureDefinition/valueset-expression', index: 1} min: 0 max: 1 compose: mustSupport: true index: 2 elements: lockedDate: {mustSupport: false, index: 3} inactive: {mustSupport: true, index: 4} include: mustSupport: true index: 5 elements: system: {mustSupport: true, index: 6} version: {mustSupport: true, index: 7} concept: {mustSupport: true, index: 8} filter: {mustSupport: true, index: 9} valueSet: {mustSupport: true, index: 10} package_version: 4.0.0 extensions: rulesText: {url: 'http://hl7.org/fhir/StructureDefinition/valueset-rules-text', min: 0, max: 1, short: Human instructions for constructing the valueset, type: Extension, mustSupport: true, index: 0} expression: {url: 'http://hl7.org/fhir/StructureDefinition/valueset-expression', min: 0, max: 1, short: Machine instructions for constructing the value set, type: Extension, mustSupport: true, index: 1} class: profile kind: resource url: http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/computable-valueset-cqfm base: http://hl7.org/fhir/StructureDefinition/shareablevalueset version: 4.0.0
