Background
The most common reason for the overstating Gross Retiree Costs error is including costs that are not covered by Medicare Part D, therefore making them ineligible for RDS subsidy during interim payments. At Reconciliation, a Plan Sponsor identifies those drugs that were not supposed to be claimed for subsidy, which consequently reduces the Gross Retiree Cost reported during interim payments and leads to an overpayment.
