Topic: CodeableConcept System URIs
Susan Crawford (Jul 07 2017 at 17:45):
When using CodeableConcept, can you intermix the system uri’s? For example, with ExplanationOfBenefit.accident.type we have some internal codes that map to the codes listed in the value set, particularly MPA (Motor vehicle accident) and WPA (Workplace accident). For these codes, we would use the system uri “http://hl7.org/fhir/v3/ActCode”. At the same time, we have some internal codes that do not map to the codes in the value set. For these codes, can we set the system uri to our own code system? For example, something like “http://company.com/claim-accident-type”.

You can do this for "example" and "extensible" bindings (define a value set with codes from different code systems), but binding of ExplanationOfBenefit.accident.type is "required", i.e. "To be conformant, codes in this element SHALL be from the specified value set.". I think you would need to define an extensions if you are not able to map all your local codes.
