"The purpose of releasing this updated report is to correct for a minor misassignment of hierarchy condition categories (HCCs) that occurred to certain issuers' 2017 benefit year HHS-RADV results which affected all 2017 benefit year HHS-RADV error rates used in the calculation of risk adjustment transfer adjustments.... While this issue did not change the risk pools impacted or the identification of outliers, it did cause small changes in the dollar amounts of the 2017 benefit year HHS-RADV adjustments to risk adjustment transfers for all issuers with transfer adjustments."
