This Code system is used in the following value sets:


The degree of equivalence between concepts.

This code system http://hl7.org/fhir/concept-map-equivalence defines the following codes:

LvlCodeDisplayDefinitionCopy
1relatedto Related ToThe concepts are related to each other, and have at least some overlap in meaning, but the exact relationship is not known.btn btn
2  equivalent EquivalentThe definitions of the concepts mean the same thing (including when structural implications of meaning are considered) (i.e. extensionally identical).btn btn
3    equal EqualThe definitions of the concepts are exactly the same (i.e. only grammatical differences) and structural implications of meaning are identical or irrelevant (i.e. intentionally identical).btn btn
2  wider WiderThe target mapping is wider in meaning than the source concept.btn btn
2  subsumes SubsumesThe target mapping subsumes the meaning of the source concept (e.g. the source is-a target).btn btn
2  narrower NarrowerThe target mapping is narrower in meaning than the source concept. The sense in which the mapping is narrower SHALL be described in the comments in this case, and applications should be careful when attempting to use these mappings operationally.btn btn
2  specializes SpecializesThe target mapping specializes the meaning of the source concept (e.g. the target is-a source).btn btn
2  inexact InexactThe target mapping overlaps with the source concept, but both source and target cover additional meaning, or the definitions are imprecise and it is uncertain whether they have the same boundaries to their meaning. The sense in which the mapping is inexact SHALL be described in the comments in this case, and applications should be careful when attempting to use these mappings operationally.btn btn
1unmatched UnmatchedThere is no match for this concept in the target code system.btn btn
2  disjoint DisjointThis is an explicit assertion that there is no mapping between the source and target concept.btn btn

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
