This is a code system defined by the FHIR project.
Defines how concepts are processed into the expansion when it's for UI presentation.
|Source Resource||XML / JSON|
This Code system is used in the following value sets:
|all-codes||All Codes||The expansion (when in UI mode) includes all codes *and* any defined groups (in extensions).|
|ungrouped||Groups + Ungrouped codes||The expanion (when in UI mode) lists the groups, and then any codes that have not been included in a group.|
|groups-only||Groups Only||The expansion (when in UI mode) only includes the defined groups.|
See the full registry of code systems defined as part of FHIR.
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|
