Millions of Medicare Part D Enrollees Have Had Out-of-Pocket Drug Spending Above the Catastrophic Threshold Over Time

Medicare Part D, the outpatient prescription drug benefit for Medicare beneficiaries, provides catastrophic coverage for high out-of-pocket drug costs, but there is no limit on the total amount that beneficiaries have to pay out of pocket each year. Policymakers on both sides of the aisle support proposals to modify the design of the Part D benefit and establish a hard cap on out-of-pocket prescription drug spending by Part D enrollees. This analysis shows the number of Part D enrollees without low-income subsidies who have exceeded the catastrophic coverage threshold annually, and over multiple years, based on 2007-2019 Part D claims data.
