No. C-CDA documents cannot be used for these purposes as the documents are electronically generated and not the same as the medical record documented in the primary source system where care was originally recorded (e.g. electronic medical record). This includes C-CDA documents received from HIEs.
HIEs support the exchange of clinical information, an important function for the delivery of care. Organizations are encouraged to use electronic files received from an HIE, such as electronic C-CDA or FHIR documents (e.g., C-CDA XML, FHIR JSON), as a supplemental data source.
