Data Structure
C-CDA Support
What is a C-CDA file?
Consolidated Clinical Document Architecture (C-CDA) is an HL7 standard that defines a structured, XML-based format for exchanging clinical documents. A C-CDA document is composed of human-readable narrative and machine-readable, coded data organized into sections and entries.
Common information contained in C-CDA documents includes:
- Patient demographics and identifiers
- Problems/diagnoses and past medical history
- Allergies and adverse reactions
- Medications and immunizations
- Procedures, surgeries, and devices
- Results (labs, imaging summaries) and vitals
- Encounters and providers
- Care plans, goals, and instructions
Document types supported
The platform supports the following clinical C-CDA document types:
- Consultation Note
- Continuity of Care Document (CCD)
- Discharge Summary
- History and Physical (H&P)
- Operative Note
- Procedure Note
- Progress Note
- Referral Note
- Transfer Summary
Requirements and validation
- Only clinical C-CDA documents are accepted. The file must be valid XML and conform to recognized C-CDA templates for one of the supported types listed above.
- Non-clinical CDA variants, unsupported C-CDA document types, or malformed XML will be rejected during ingestion.
Error behavior
If the uploaded file is not a supported clinical C-CDA or the XML is invalid, the platform will return an error such as:
In some cases, additional context may be provided (for example, “Unsupported C-CDA document type”). Ensure your file is a valid clinical C-CDA for one of the supported types.
