Description
The structure for coding in CDA and FHIR are fundamentally different. CDA employs a mechanism (xsi:type CD or CE) where the code is included in the element and then originalText and translations elements may be provided as child elements. In FHIR, CodeableConcept places all codes in a coding list with a separate element for the text representation.
It may be worth adding some additional guidance that the root @code/@codeSystem goes in the first coding array element, and then translations follow in the order they are sent in CDA. An exception would be if the root @code/@codeSystem contained a nullFlavor like 'OTH' (in the event that CDA required, for example, a SNOMED code). In this case, it doesn't make sense to populate a FHIR coding element with a null value, so it could just be omitted at this point (unless US Core required the same vocabulary).
