1.22.2.1.2.1 DataAbsentReason

Used to specify why the normally expected content of the data element is missing

This value set defines its own terms in the system http://hl7.org/fhir/data-absent-reason

CodeDefinitionv3 Map (NullFlavor)
unknown The value is not known=UNK
asked The source human does not know the value=ASKU
temp There is reason to expect (from the workflow) that the value may become known=NAV
notasked The workflow didn't lead to this value being known=NASK
masked The information is not available due to security, privacy or related reasons=MSK
unsupported The source system wasn't capable of supporting this element>NA
astext The content of the data is represented in the resource narrative
error Some system or workflow process error means that the information is not available>NA

This value set is used in the following places:

Explanation of the columns that may appear on this page:

LevelA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance)
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
DefinitionAn explanation of the meaning of the concept
CommentsAdditional notes about how to use the code

In addition, this page will include mappings to HL7 v2 or HL7 v3 code where these have been defined.
