unknownmaps to wider conceptNI (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'.
