The Risk Adjustment Factor (RAF) score is a core component of hierarchical condition category (HCC) risk adjustment models. It is a numerical value that represents a beneficiary's relative health status. It is calculated using the individual's demographic information (e.g., age, gender, Medicaid status) and their documented chronic and severe health conditions (HCCs). The score predicts the probable future healthcare costs for that individual compared to an average beneficiary, allowing for accurate prospective payments to health plans.

A: RAF scores are used to adjust payments to health plans for future costs, not to directly reimburse individual providers.

B: The RAF score is based on both demographic factors and, most significantly, the beneficiary's documented health conditions (diagnoses).

D: RAF scores are used to adjust prospective, capitated payments to health plans, not to calculate reimbursement for individual office visits.
