## Highlights

The Centers for Medicare & Medicaid Services (CMS) allows Part D plans to utilize different tiers with different levels of cost sharing as a way of managing drug utilization and spending. One such tier, the specialty tier, is designed for high-cost drugs whose prices exceed a certain threshold set by CMS. Beneficiaries who use these drugs typically face higher out-of-pocket costs than beneficiaries who use only lower-cost drugs. This testimony is based on GAO's January 2010 report entitled Medicare Part D: Spending, Beneficiary Cost Sharing, and Cost-Containment Efforts for High-Cost Drugs Eligible for a Specialty Tier (GAO-10-242) in which GAO examined, among other things, (1) Part D spending on these drugs in 2007, the most recent year for which claims data were available; (2) how different cost-sharing structures could be expected to affect beneficiary out-of-pocket costs; (3) how negotiated drug prices could be expected to affect beneficiary out-of-pocket costs; and (4) information Part D plan sponsors reported on their ability to negotiate price concessions. For the second and third of these objectives, this testimony focuses on out-of-pocket costs for beneficiaries responsible for paying the full cost-sharing amounts required by their plans. GAO examined CMS data and interviewed officials from CMS and 8 of the 11 largest plan sponsors, based on enrollment in 2008. Seven of the 11 plan sponsors provided price concession data for a sample of 20 drugs for 2006 through 2008.
