This report presents findings from an analysis of the Medicare Part D marketplace in 2013 and changes in drug coverage and costs since 2006. It presents key findings related to Medicare drug plan availability, enrollment, premiums, low-income subsidies, the coverage gap, benefit design, cost sharing, formularies, and utilization management, based on data from CMS for all plans participating in Part D. The analysis was conducted jointly by researchers at Georgetown University, the Kaiser Family Foundation and the National Opinion Research Center at the University of Chicago.
The 2014 Part D Data Spotlight analyzes information about the Medicare Part D stand-alone prescription drug plan (PDP) options available to beneficiaries in 2014. The analysis shows that Medicare beneficiaries on average will have a choice of 35 stand-alone prescription drug plans in 2014, and somewhat more “benchmark” plans available to Low-Income Subsidy (LIS) beneficiaries nationwide. The weighted average premium will increase by 5 percent between 2013 and 2014 if enrollees remain in the same plans next year. The analysis also finds more plans are using preferred pharmacy networks and adopting a growing number of cost-sharing formulary tiers for different drugs.
On January 1, 2006, the six million Americans who are covered by both Medicare and Medicaid saw a change in how their prescription drugs are covered. The dual eligible population was transitioned from Medicaid into the Medicare prescription drug benefit. As a group, these beneficiaries are poorer and sicker than those on Medicare. Consequently, they have more extensive health and prescription drug needs than most Medicare beneficiaries.
Transitions is a video that explores some of the issues and challenges “dual eligibles” may face during the transition from Medicaid drug coverage to Medicare.
