RAF values are used to adjust Medicare Advantage payments based on enrollees’ health status. The Centers for Medicare & Medicaid Services, a component of the Department of Health and Human Services, runs the Medicare Advantage program and applies these risk-adjusted payments using the RAF scores. This makes CMS the agency that uses RAF values for MA payments. The other options don’t fit because the UK’s National Health Service operates a different system, and while HHS oversees CMS, the specific calculation and application of RAF-based MA payments is handled by CMS.
