Logical Model: CR: ConceptRole (V3 Data Type)

Official URL: http://hl7.org/cda/stds/core/StructureDefinition/CR Version: 1.0.0
Active as of 2025-08-28 Maturity Level: 1 Responsible: HL7 Computable Name: CR

A concept qualifier code with optionally named role. Both qualifier role and value codes must be defined by the coding system of the CD containing the concept qualifier. For example, if SNOMED RT defines a concept "leg", a role relation "has-laterality", and another concept "left", the concept role relation allows to add the qualifier "has-laterality: left" to a primary code "leg" to construct the meaning "left leg".
