Hi - I am wondering if there is a way to convert a given CDA into HL7(v2) message. Is there a library out there that does this transformation?

HL7 v2 messages are mostly transactional, and CDA documents are mostly retrospective, self-contained, immutable representation of provided care. They are not interchangeable, and there can't be a general way to transform one into the other.

The CDA specification does describe a way to use an HL7 v2 message as a transport of a CDA document, but there is no conversion there.

@Vassil Peytchev Cool, thanks for the info. If I understood it correctly, we can build a CDA from a HL7 but not the other way round.

CDA, v2 and FHIR are all "HL7".

@Lloyd McKenzie 100% agreed. I meant HL7(v2)

one can transport a CDA document in an HL7 v2 message . There are other transports defined as well, such as XDS from IHE.
