1.23.2.1.306 Value Set for codes in http://hl7.org/fhir/concept-equivalence

This is a value set defined by the FHIR project.

Summary

Code System URL:	http://hl7.org/fhir/concept-equivalence
Value Set URL:	http://hl7.org/fhir/vs/concept-equivalence
Definition:	The degree of equivalence between concepts

Formal value Set definition : XML or JSON.

This value set defines its own codes:

This value set contains 9 concepts

1.23.2.1.306.1 ConceptMapEquivalence

The degree of equivalence between concepts

This value set defines its own terms in the system http://hl7.org/fhir/concept-equivalence

Lvl	Code	Display	Definition
1	equivalent	Equivalent	The definitions of the concepts mean the same thing (including when structural implications of meaning are considered) (i.e. extensionally identical).
2	equal	Equal	The definitions of the concepts are exactly the same (i.e. only grammatical differences) and structural implications of meaning are identifical or irrelevant (i.e. intensionally identical).
1	wider	Wider	The target mapping is wider in meaning than the source concept.
2	subsumes	Subsumes	The target mapping subsumes the meaning of the source concept (e.g. the source is-a target).
1	narrower	Narrower	The target mapping is narrower in meaning that 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 atempting to use these mappings operationally.
2	specialises	Specialises	The target mapping specialises the meaning of the source concept (e.g. the target is-a source).
1	inexact	Inexact	The 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 narrower SHALL be described in the comments in this case, and applications should be careful when atempting to use these mappings operationally.
1	unmatched	Unmatched	There is no match for this concept in the destination concept system.
2	disjoint	Disjoint	This is an explicit assertion that there is no mapping between the source and target concept.

Explanation of the columns that may appear on this page:

Level

A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance)

Display

The 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

Definition

An explanation of the meaning of the concept

Comments

Additional notes about how to use the code

In addition, this page will include mappings to HL7 v2 or HL7 v3 code where these have been defined.
