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

Lvl Code Display Definition Copy
1 relatedto Related To The 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 Equivalent The definitions of the concepts mean the same thing (including when structural implications of meaning are considered) (i.e. extensionally identical). btn   btn
3     equal Equal The 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 Wider The target mapping is wider in meaning than the source concept. btn   btn
2   subsumes Subsumes The target mapping subsumes the meaning of the source concept (e.g. the source is-a target). btn   btn
2   narrower Narrower The 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 Specializes The target mapping specializes the meaning of the source concept (e.g. the target is-a source). btn   btn
2   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 inexact SHALL be described in the comments in this case, and applications should be careful when attempting to use these mappings operationally. btn   btn
1 unmatched Unmatched There is no match for this concept in the target code system. btn   btn
2   disjoint Disjoint This 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:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
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). If the code is in italics, this indicates that the code is not selectable ('Abstract')
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
