Basis for membership in a group

This case-sensitive code system http://hl7.org/fhir/group-membership-basis defines the following codes:

definitional DefinitionalThe Group.characteristics specified are both necessary and sufficient to determine membership. All entities that meet the criteria are considered to be members of the group, whether referenced by the group or not. If members are present, they are individuals that happen to be known as meeting the Group.characteristics. The list cannot be presumed to be complete.btn btn
conceptual ConceptualThe Group.characteristics specified are both necessary and sufficient to determine membership. The 'conceptual' Group is a 'definitional' Group in which the Group.type is not bound to FHIR types.btn btn
enumerated EnumeratedThe Group.characteristics are necessary but not sufficient to determine membership. Membership is determined by being listed as one of the Group.member.btn btn

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.

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
