Expansion based on codesystem DataAbsentReason v1.0.0 (CodeSystem) icon

This value set contains 15 concepts.

1  unknown iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonUnknown

The value is expected to exist but is not known.

2    asked-unknown iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonAsked But Unknown

The source was asked but does not know the value.

2    temp-unknown iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonTemporarily Unknown

There is reason to expect (from the workflow) that the value may become known.

2    not-asked iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNot Asked

The workflow didn't lead to this value being known.

2    asked-declined iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonAsked But Declined

The source was asked but declined to answer.

1  masked iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonMasked

The information is not available due to security, privacy or related reasons.

1  not-applicable iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNot Applicable

There is no proper value for this element (e.g. last menstrual period for a male).

1  unsupported iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonUnsupported

The source system wasn't capable of supporting this element.

1  as-text iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonAs Text

The content of the data is represented in the resource narrative.

1  error iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonError

Some system or workflow process error means that the information is not available.

2    not-a-number iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNot a Number (NaN)

The numeric value is undefined or unrepresentable due to a floating point processing error.

2    negative-infinity iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNegative Infinity (NINF)

The numeric value is excessively low and unrepresentable due to a floating point processing error.

2    positive-infinity iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonPositive Infinity (PINF)

The numeric value is excessively high and unrepresentable due to a floating point processing error.

1  not-performed iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNot Performed

The value is not available because the observation procedure (test, etc.) was not performed.

1  not-permitted iconhttp://terminology.hl7.org/CodeSystem/data-absent-reasonNot Permitted

The value is not permitted in this context (e.g. due to profiles, or the base data types).

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
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). If the code is in italics, this indicates that the code is not selectable ('Abstract')
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
