A uniquely identifiable set of valid concept representations, where any concept representation can be tested to determine whether or not it is a member of the value set.


  • This definition is used in HL7 Vocabulary Committee documents and FHIR specifications.
  • The role of a value set is to constrain the permissible content for a particular use (e.g. data entry into a particular field).
  • In SNOMED CT a concept representation may be a concept identifier or a SNOMED CT expression
  • A reference set can be used to represent a value set of SNOMED CT concepts each of which is represented by a concept identifier in the referencedComponentId field.
