Logical Model: CR: ConceptRole (V3 Data Type)

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”.

Usage:

• Use this Logical Model Profile: CD: ConceptDescriptor (V3 Data Type) and CE: CodedWithEquivalents (V3 Data Type)
