Use of SNOMED CT concept Identifiers to represent of a set of values for a property of a particular type of SNOMED CT component.


  • Concept enumeration serves the same general purpose as more general approaches to providing enumerated lists of values. However, the use of concept identifiers, rather than a sequential or arbitrary set of numbers, allows the human readable meaning of each enumeration to be accessed in the same way as terms associated with clinical concepts. Additionally, use of a hierarchical parent to specify the permitted values, enables the range of values to be updated when necessary.
  • The SNOMED CT concepts used to represent concept enumerations are usually subtype children (or descendants) of a relevant general concept in the SNOMED CT metadata hierarchy. Each possible value is represented by a single child concept.
