In HCC coding, additional diagnosis codes may be submitted on a supplemental file; what is the primary reason for such supplemental submissions?

• A. Supplemental file submissions.
• B. Automated patient self-entry.
• C. Random sampling.
• D. Provider credential verification.

Answer: (A)

In risk adjustment for HCC coding, supplemental submissions exist to capture additional diagnoses that may affect a patient’s risk score but aren’t included on the main claim. This allows the coder to report more of the patient’s active conditions so the risk adjustment model reflects their true health status, leading to more accurate risk scores and payments. The other options don’t fit this purpose: automated patient self-entry isn’t the mechanism used to report diagnostically relevant codes for risk adjustment; random sampling is about audits, not submitting extra diagnoses; and provider credential verification concerns credentials, not the submission of diagnoses.
