Lvl Level Code Display Definition
0 1    unknown Unknown The value is expected to exist but is not known.
1 2         asked-unknown Asked But Unknown The source was asked but does not know the value.
1 2         temp-unknown Temporarily Unknown There is reason to expect (from the workflow) that the value may become known.
1 2         not-asked Not Asked The workflow didn't lead to this value being known.
1 2         asked-declined Asked But Declined The source was asked but declined to answer.
0 1    masked Masked The information is not available due to security, privacy or related reasons.
0 1    not-applicable Not Applicable There is no proper value for this element (e.g. last menstrual period for a male).
0 1    unsupported Unsupported The source system wasn't capable of supporting this element.
0 1    as-text As Text The content of the data is represented in the resource narrative.
0 1    error Error Some system or workflow process error means that the information is not available.
1 2         not-a-number Not a Number (NaN) The numeric value is undefined or unrepresentable due to a floating point processing error.
1 2         negative-infinity Negative Infinity (NINF) The numeric value is excessively low and unrepresentable due to a floating point processing error.
1 2         positive-infinity Positive Infinity (PINF) The numeric value is excessively high and unrepresentable due to a floating point processing error.
0 1    not-performed Not Performed The value is not available because the observation procedure (test, etc.) was not performed.
0 1    not-permitted Not 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:

Lvl A 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
Source 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). If the code is in italics, this indicates that the code is not selectable ('Abstract')
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
