Properties

This code system defines the following properties for its concepts

NameCodeTypeDescription
inactive inactive boolean Whether the code is active or not (defaults to false).
sufficientlyDefined sufficientlyDefined boolean True if the description logic definition of the concept includes sufficient conditions (i.e., if the concept is not primitive).
parent parent code The SNOMED CT concept id that is a direct parent of the concept.
child child code The SNOMED CT concept id that is a direct child of the concept.
moduleId moduleId code The SNOMED CT concept id of the module that the concept belongs to.
