Why is coding accuracy important in the RADV audit process?

• A. Coding accuracy is irrelevant to the risk score.
• B. Inaccurate coding can hide patient health risks.
• C. Accurately coding ensures a true picture of patient health and affects risk scores.
• D. Coding accuracy only affects billing speed.

Answer: (C)

Coding accuracy matters because the RADV process uses diagnosis codes to represent a patient’s health status, and those codes directly determine risk scores used for payment. In CMS risk adjustment, each diagnosed condition maps to a specific HCC with a weight; when codes are complete and correct, the risk score reflects the patient’s true health burden. If codes are missing or incorrect, the score can be understated or overstated, leading to inappropriate payments and potential audit findings. RADV audits compare claims data with medical records to ensure the codes are supported by documentation, so precise coding supports accurate risk assessment and compliance. In short, accurate coding provides a true picture of patient health and directly affects the calculated risk scores.
