This brief provides an overview of the Medicare Part D prescription drug benefit, including current data on plan availability, enrollment, and spending and financing, and highlights changes made under the Inflation Reduction Act.
This brief looks at premium changes for Medicare Part D stand-alone prescription drug plans between 2025 and 2026. For plans that were offered nationwide in 2025 and will continue to be offered in 2026, Part D enrollees in many states will see lower monthly premiums in 2026.
This Health Policy 101 chapter explores Medicare, a federal health insurance program covering more than 68 million people, established in 1965 for people age 65 or older and later expanded to cover people under age 65 with long-term disabilities. In addition to detailing Medicare eligibility, coverage, and spending, the chapter examines the increased role of private plans in providing benefits and the financing challenges posed by increasing health care costs and an aging population.
This brief analyzes changes in the new tax and budget reconciliation law that modify which drugs will be selected for Medicare drug price negotiation, which will lead to higher Medicare spending and higher costs for beneficiaries who take these medications.
This issue brief describes the impact of H.R.1's 10-year delay in implementing provisions in two Medicaid eligibility rules that would have reduced red tape. The delayed rules are projected to decrease federal spending and future Medicaid and CHIP enrollment and increase coverage loss.
In announcing these changes, CMS states that it is “facilitating the Part D program’s return to operating under regular market conditions.” Increasingly, however, these regular conditions appear unfavorable to the ongoing stability of the stand-alone prescription drug plan market, further tilting the playing field towards Medicare Advantage.
Voluntary efforts by drug companies to lower prices on selected medications, such as this new discounted price for Eliquis and previous price reductions on certain insulin products, could expand access to lower-priced drugs for some patients, but are not likely to improve prescription drug affordability in the U.S. on a widespread basis.
This brief focuses on the stand-alone Medicare Part D prescription drug plan marketplace and its somewhat uncertain future, in light of recent trends in plan availability and the potential for another year of premium increases in 2026, in part depending on what the Trump administration decides to do with the temporary Part D premium stabilization demonstration. The brief explains why the stability of the PDP market matters, both for people in traditional Medicare who want prescription drug coverage but also for the viability of traditional Medicare as an option vis a vis Medicare Advantage.
This brief considers how default enrollment into Medicare Advantage might work, potential challenges with this approach, and implications for beneficiaries, insurers, providers, agents and brokers, and the federal budget.
To understand the role of Medicare Part D stand-alone prescription drug plans in serving rural Medicare beneficiaries, this data note analyzes 2025 Part D enrollment in PDPs and Medicare Advantage drug plans by geographic area nationally and at the state level.
