## Abstract

This final rule adopts certain changes to the risk adjustment data validation error estimation methodology beginning with the 2019 benefit year for states where the Department of Health and Human Services (HHS) operates the risk adjustment program. This rule is finalizing changes to the HHS-RADV error estimation methodology, which is used to calculate adjusted risk scores and risk adjustment transfers, beginning with the 2019 benefit year of HHS-RADV. This rule also finalizes a change to the benefit year to which HHS-RADV adjustments to risk scores and risk adjustment transfers would be applied beginning with the 2020 benefit year of HHS-RADV. These policies seek to further the integrity of HHS-RADV, address stakeholder feedback, promote fairness, and improve the predictability of HHS-RADV adjustments.
