Designation of a concept's state. Normally is not populated unless the state is retired.

This code system http://terminology.hl7.org/CodeSystem/v3-MapRelationship defines the following codes:

Code	Display	Definition	internalId	status
BT	Broader Than	The first concept is at a more abstract level than the second concept. For example, Hepatitis is broader than Hepatitis A, and endocrine disease is broader than Diabetes Mellitus. Broader than is the opposite of the narrower than relationship.	11054	active
E	Exact	The two concepts have identical meaning.	11053	active
NT	Narrower Than	The first concept is at a more detailed level than the second concept. For example, Pennicillin G is narrower than Pennicillin, and vellus hair is narrower than hair. Narrower than is the opposite of broader than.	11055	active
