Beneficiary Cost-Sharing in Part D

A priority of OIG and HHS is to lower drug spending for people and programs. In Medicare Part D, as drug costs rise, the amount that beneficiaries pay out-of-pocket also increases. This amount—known as beneficiary cost-sharing—is not capped in Part D. As a result, some beneficiaries may have high out-of-pocket costs for their prescriptions. If beneficiaries' costs become unaffordable, they may skip doses of medication or forgo purchasing it altogether. This data brief will provide in-depth data on the amount beneficiaries pay out-of-pocket for Part D drugs. It will also determine the proportion of beneficiaries who have high cost-sharing and describe these beneficiaries and the drugs they commonly receive, including the proportion of drugs that are high cost.
