Code Display Definition
unknown Unknown The value is not known.
asked Asked The source human does not know the value.
temp Temp There is reason to expect (from the workflow) that the value may become known.
not-asked Not Asked The workflow didn't lead to this value being known.
masked Masked The information is not available due to security, privacy or related reasons.
unsupported Unsupported The source system wasn't capable of supporting this element.
astext As Text The content of the data is represented in the resource narrative.

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) 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
