description: 'Information on whether an increase or decrease in score is the preferred result (e.g., a higher score indicates better quality OR a lower score indicates better quality OR quality is within a range).\n\n**Additional Guidance: improvementNotation**\n\n`Reference range` with definition of score within a defined interval (or a “passing score” over or under a certain threshold) indicates better quality to the improvement notation value set. Please provide comments on this additional code and if there are other codes needed in this value set.\n\nPlease provide comments on this additional code and if there are other codes needed in the improvement notation value set.\n\nIf an additional code is added to the improvement notation (like normative reference range as suggested), where is guidance about the reference range best included in the specification for implementer use? Some suggestions include: the guidance field, the rate aggregation field or adding an extension to improvementNotation to add text.' package_name: hl7.fhir.us.cqfmeasures derivation: constraint name: CQFMImprovementNotation type: Extension elements: url: type: uri pattern: {type: Uri, value: 'http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/cqfm-improvementNotation'} index: 0 value: choices: [valueCodeableConcept] index: 2 valueCodeableConcept: {type: CodeableConcept, choiceOf: value, index: 3} package_version: 5.0.0-ballot2 class: extension kind: complex-type url: http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/cqfm-improvementNotation base: http://hl7.org/fhir/StructureDefinition/Extension version: 4.0.0
