Generated Narrative: ValueSet R3-v3-MapRelationship-for-R4B

This value set expansion contains 3 concepts.

Code	System	Display	Definition
BT	http://hl7.org/fhir/v3/MapRelationship	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.
E	http://hl7.org/fhir/v3/MapRelationship	Exact	The two concepts have identical meaning.
NT	http://hl7.org/fhir/v3/MapRelationship	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.
