### Logical Definition (CLD)

- Include these codes as defined in `http://terminology.hl7.org/CodeSystem/data-absent-reason` version 📍1.0.0

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

Explanation of the columns that may appear on this page:

Level | A 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
System | The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code | The code (used as the code in the resource instance)
Display | The 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
Definition | An explanation of the meaning of the concept
Comments | Additional notes about how to use the code
