The measure scoring value set uses FHIR-defined codes, rather than the HL7 V3 codes used in HQMF. This was a conscious decision to start with a clean slate. However, the QM IG needs a concept mapping:

HL7 V3 ValueSet: https://terminology.hl7.org/ValueSet-v3-ObservationMeasureScoring.html

FHIR ValueSet: http://hl7.org/fhir/R4/valueset-measure-scoring.html

V3 -> FHIR

PROPOR -> proportion

CONTVAR -> continuous-variable

COHORT -> cohort

RATIO -> ratio
