Which action helps verify the integrity of a received CCDA?

• A. Validate XML against CCDA schema
• B. Confirm required sections
• C. Check patient identifiers
• D. Validate XML against CCDA schema, confirm required sections, check patient identifiers, and verify source data consistency

Answer: (D)

Verifying a received CCDA requires layered validation to ensure the document is structurally sound, complete, and trustworthy. Validating the XML against the CCDA schema checks that the document is well-formed and follows the expected structure and data types. Confirming the required sections ensures the CCDA contains all the essential parts defined by the profile, so nothing critical is missing. Checking patient identifiers verifies that the record matches the correct patient and helps prevent misattribution. Verifying source data consistency cross-checks key data points against the originating system to detect discrepancies or tampering during transmission. Together, these steps provide a comprehensive assurance of integrity, making the combined set of checks the best approach.
