Generated Narrative: CodeSystem data-absent-reason

Last updated: 2019-11-01 09:29:23+1100; Language: en

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

Lvl | Code | Display | Definition
1 | unknown | Unknown | The value is expected to exist but is not known.
2 | asked-unknown | Asked But Unknown | The source was asked but does not know the value.
2 | temp-unknown | Temporarily Unknown | There is reason to expect (from the workflow) that the value may become known.
2 | not-asked | Not Asked | The workflow didn't lead to this value being known.
2 | asked-declined | Asked But Declined | The source was asked but declined to answer.
1 | masked | Masked | The information is not available due to security, privacy or related reasons.
1 | not-applicable | Not Applicable | There is no proper value for this element (e.g. last menstrual period for a male).
1 | unsupported | Unsupported | The source system wasn't capable of supporting this element.
1 | as-text | As Text | The content of the data is represented in the resource narrative.
1 | error | Error | Some 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.
1 | not-performed | Not Performed | The value is not available because the observation procedure (test, etc.) was not performed.
1 | not-permitted | Not Permitted | The value is not permitted in this context (e.g. due to profiles, or the base data types).

# concept[].definition
The value is expected to exist but is not known.

# concept[].concept[].definition
The source was asked but does not know the value.

# concept[].concept[].definition
There is reason to expect (from the workflow) that the value may become known.

# concept[].concept[].definition
The workflow didn't lead to this value being known.

# concept[].concept[].definition
The source was asked but declined to answer.

# concept[].extension[].valueString
Using "masked" may be breach of security or confidentiality, but there are times        when its use is required to support alternate workflows for gaining access to denied information.

# concept[].definition
The information is not available due to security, privacy or related reasons.

# concept[].definition
There is no proper value for this element (e.g. last menstrual period for a male).

# concept[].definition
The source system wasn't capable of supporting this element.

# concept[].extension[].valueString
It may be linked by internal references (e.g. xml:id). This usually implies that the value        could not be represented in the correct format - this may be due to system limitations,        or this particular data value.

# concept[].definition
The content of the data is represented in the resource narrative.

# concept[].definition
Some system or workflow process error means that the information is not available.

# concept[].concept[].extension[].valueString
This is sometimes an output value from measuring devices.

# concept[].concept[].definition
The numeric value is undefined or unrepresentable due to a floating point processing error.

# concept[].concept[].extension[].valueString
This is sometimes an output value from measuring devices.

# concept[].concept[].definition
The numeric value is excessively low and unrepresentable due to a floating point processing        error.

# concept[].concept[].extension[].valueString
This is sometimes an output value from measuring devices.

# concept[].concept[].definition
The numeric value is excessively high and unrepresentable due to a floating point processing        error.

# concept[].definition
The value is not available because the observation procedure (test, etc.) was not performed.

# concept[].extension[].valueString
This is most often associated with required bindings that do not include the actual code        used, but may be used with other data types.

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