This value set contains 6 concepts

1.22.2.1.10.1 SpecialValues

A set of generally useful codes defined so they can be included in value sets

This value set defines its own terms in the system http://hl7.org/fhir/special-values

CodeDisplayDefinition
true trueBoolean true
false falseBoolean false
trace Trace Amount DetectedThe content is greater than zero, but too small to be quantified
sufficient Sufficient QuantityThe specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material
withdrawn Value WithdrawnThe value is no longer available
nil-known Nil KnownThe are no known applicable values in this context

This value set is not currently used

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.
