Generated Narrative: CodeSystem data-absent-reason

This case-sensitive code system http://terminology.hl7.org/CodeSystem/data-absent-reason defines the following codes in an undefined hierarchy:

LvlCodeDisplayDefinition
1unknown UnknownThe value is expected to exist but is not known.
2  asked-unknown Asked But UnknownThe source was asked but does not know the value.
2  temp-unknown Temporarily UnknownThere is reason to expect (from the workflow) that the value may become known.
2  not-asked Not AskedThe workflow didn't lead to this value being known.
2  asked-declined Asked But DeclinedThe source was asked but declined to answer.
1masked MaskedThe information is not available due to security, privacy or related reasons.
1not-applicable Not ApplicableThere is no proper value for this element (e.g. last menstrual period for a male).
1unsupported UnsupportedThe source system wasn't capable of supporting this element.
1as-text As TextThe content of the data is represented in the resource narrative.
1error ErrorSome system or workflow process error means that the information is not available.
2  not-a-number Not a Number (NaN)The numeric value is undefined or unrepresentable due to a floating point processing error.
2  negative-infinity Negative Infinity (NINF)The numeric value is excessively low and unrepresentable due to a floating point processing error.
2  positive-infinity Positive Infinity (PINF)The numeric value is excessively high and unrepresentable due to a floating point processing error.
1not-performed Not PerformedThe value is not available because the observation procedure (test, etc.) was not performed.
1not-permitted Not PermittedThe value is not permitted in this context (e.g. due to profiles, or the base data types).
