concept enumeration
A set of SNOMED CT concept identifiers used to represent values for a property of a SNOMED CT component or reference set member.
Notes
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.
Example
Concept enumerations for description.typeId:
900000000000446008 |Description type (core metadata concept)| 900000000000003001 |Fully specified name (core metadata concept)| 900000000000013009 |Synonym (core metadata concept)| 900000000000550004 |Definition (core metadata concept)|
