Extension: CQFM Direct Reference Code

Official URL: http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/cqfm-directReferenceCode Version: 4.0.0-ballot
Active as of 2019-02-13 Computable Name: CQFMDirectReferenceCode

Defines a code directly referenced by measure logic, as opposed to a value set. Direct reference codes may be the target of data requirements.

A computable measure must specify terminology requirements. Direct reference codes SHALL be at least the set of all codes defined in the primary measure library and any referenced libraries, recursively, and SHOULD be limited to only those direct reference codes that are actually referenced in expressions used by the measure.
