When diagnoses should be combo coded and guidelines allow it, why is combo coding important?

• A. It reduces the RAF to avoid overbilling
• B. It does not affect the RAF
• C. It has no impact on risk adjustment
• D. It's very important to combo code; otherwise the RAF will be lower

Answer: (D)

Combo coding matters because the risk-adjustment model weighs conditions to reflect a patient’s true health risk. When a combination code is available and appropriate, it communicates both conditions and their relationship in a way that often places the patient into a higher-weighted category. That higher weight translates into a higher risk adjustment factor (RAF), which better matches the patient’s actual resource use. If you skip the combo code when guidelines allow it and code the conditions separately, you may miss that increased risk, resulting in a lower RAF. For example, diabetes with nephropathy is more severe than diabetes alone, and using the combo code helps ensure the patient’s risk is captured at the appropriate level.
