Official URL: http://hl7.org/fhir/StructureDefinition/valueset-expand-group Version: 5.2.0-ballot
Standards status: Deprecated Maturity Level: 1 Responsible: HL7 International / Terminology Infrastructure Computable Name: ValueSetExpandGroup

This extension declares a group of concepts that is generated into the ValueSet.expansion.contains hierarchy when the expansion is generated for a UI. THere is no inherent assigned meaning to the hierarchy; it is used to help the user navigate the concepts. Each group has a display and/or a code, and a list of members, which are either concepts in the value set, or other groups (by code).

    Summary

    Complex Extension: This extension declares a group of concepts that is generated into the ValueSet.expansion.contains hierarchy when the expansion is generated for a UI. THere is no inherent assigned meaning to the hierarchy; it is used to help the user navigate the concepts. Each group has a display and/or a code, and a list of members, which are either concepts in the value set, or other groups (by code).

    • code: code: A reference to a code from the include.system that defines the meaning associated with the group. Note that including the code in this extension does not include the code in the value set; if the code is intended to be in the value set, it must be listed directly as well.
    • display: string: The description for the group (goes in ValueSet.expansion.contains.dispaly). All groups need a display; this can only be omitted if there is a code that can be used to determine the display.
    • member: code: One of more codes that identify codes in the expansion or other groups.
