Logical Model: CD: ConceptDescriptor (V3 Data Type)

A concept descriptor represents any kind of concept usually by giving a code defined in a code system. A concept descriptor can contain the original text or phrase that served as the basis of the coding and one or more translations into different coding systems. A concept descriptor can also contain qualifiers to describe, e.g., the concept of a “left foot” as a postcoordinated term built from the primary code “FOOT” and the qualifier “LEFT”. In cases of an exceptional value, the concept descriptor need not contain a code but only the original text describing that concept.
