Group 1 Mapping from DataAbsentReason to NullFlavor
| Source Code | Relationship | Target Code | Comment |
| unknown | maps to wider concept | NI (NoInformation) | In CDA, 'UNK' means 'a proper value is applicable, but not known.' Guidance has been to use this when the value is known to exist and to use the broader 'NI' when no specific information about why the value is unknown. FHIR's data absent reason of 'unknown' better maps to 'NI'. |
| asked-unknown (Asked But Unknown) | is equivalent to | ASKU (asked but unknown) | |
| temp-unknown (Temporarily Unknown) | is equivalent to | NAV (temporarily unavailable) | |
| not-asked | is equivalent to | NASK (not asked) | |
| asked-declined (Asked But Declined) | maps to wider concept | UNK (unknown) | |
| masked | is equivalent to | MSK (masked) | |
| not-applicable | is equivalent to | NA (not applicable) | |
| unsupported | maps to wider concept | NI (NoInformation) | |
| as-text | maps to wider concept | OTH (other) | |
| error | maps to wider concept | NAV (temporarily unavailable) | |
| not-a-number (Not a Number (NaN)) | maps to wider concept | OTH (other) | |
| negative-infinity (Negative Infinity (NINF)) | is equivalent to | NINF (negative infinity) | |
| positive-infinity (Positive Infinity (PINF)) | is equivalent to | PINF (positive infinity) | |
| not-performed | maps to wider concept | NASK (not asked) | |
| not-permitted | maps to wider concept | OTH (other) |
