How are RAF values combined when multiple HCCs are present in the same calendar year?

• A. Only the most severe condition is counted.
• B. The RAF values for all conditions are averaged.
• C. RAF values for multiple conditions are multiplied.
• D. RAF values for all three conditions are added together.

Answer: (D)

The key idea is that each HCC diagnosis has a numerical weight that represents its contribution to expected healthcare costs. When a patient has multiple distinct HCCs in the same calendar year, those weights are added together to form the overall RAF. This additive approach reflects how risk accumulates with multiple health issues, rather than picking only the single most severe, averaging, or multiplying the weights. Note that if several codes map to the same HCC category, they’re not counted separately; you count that HCC once, and only add weights from distinct HCCs. The final RAF typically includes these summed HCC weights plus demographic adjustments to reflect overall risk.
