CDA to FHIR FAQ.
Common questions about CDA R2 and C-CDA to FHIR R4 conversion — what it is, supported documents, what Redix adds, and how it is scoped.
What is Redix CDA to FHIR conversion?
CDA and C-CDA to FHIR R4 conversion offered through a Redix-supported REST API workflow. It is built on an open-source CDA-to-FHIR foundation, with Redix REST API integration, testing, selected reliability fixes, and deployment support layered on top.
It is offered alongside Redix FHIR modernization tools and is scoped separately from the Redix native C conversion engine.
What document types are supported?
Common CDA and C-CDA inputs include:
- Continuity of Care Document (CCD)
- Discharge Summary
- Progress Notes
- History & Physical
- Consultation Notes
- Operative Notes
- Other clinical document types
Exact coverage should be confirmed against your sample documents.
What FHIR resources does it produce?
Typical output includes core FHIR R4 resources such as Patient, Practitioner, Organization, Encounter, Observation, Condition, Medication, MedicationRequest, AllergyIntolerance, Procedure, Immunization, DocumentReference, and Composition.
The exact resource set and field coverage depend on the source documents and should be validated against your samples.
What C-CDA sections are supported?
- Problems — active and resolved conditions
- Medications — current and past medications
- Allergies — allergies and adverse reactions
- Results — lab results and diagnostic data
- Procedures — past surgical and clinical procedures
- Immunizations — vaccination history
- Vital Signs — recent vital sign readings
- Social History — smoking status and social factors
Exact section handling should be confirmed against your sample documents.
Does this require the Redix native C engine?
No. CDA and C-CDA to FHIR is open-source-based and scoped separately from the Redix native C conversion engine.
It is accessed through a Redix REST API and runs on Linux or Windows, on-premises or in Docker.
