A set of SNOMED CT concept identifiers used to represent values for a property of a SNOMED CT component or reference set member.


  • Concept enumeration serves the same purpose as more general approaches to providing enumerated lists of values (i.e. assigning a number to a value). However, the use of SNOMED CT concept identifier allows access to the human readable meaning of each enumeration using descriptions in the same way for other concepts.
  • The SNOMED CT concepts used to represent concept enumerations are usually subtype children (or descendants) of concepts in the SNOMED CT metadata hierarchy. Each possible value is represented by a single child concept. This allows updates to the permitted values to be tracked using the component history mechanism.
