Medicare Part D

Premiums Are Decreasing for Many Stand-Alone Part D Drug Plans in a Number of States in 2026

This analysis finds that monthly premiums for many Part D stand-alone prescription drug plans (PDPs) in a number of states will be lower in 2026 than they were this year. At the same time, the total number of PDPs, which provide prescription drug coverage to people in traditional Medicare, will fall for the third year in a row, as insurers continue to scale back their offerings and adjust to higher costs under the redesigned Part D benefit, reflecting changes in the Inflation Reduction Act.

  • The Latest on Geographic Variation in Medicare Spending: A Demographic Divide Persists But Variation Has Narrowed

    Report

    This report uses the most current data available to analyze Medicare per beneficiary spending, by county, in 2013; the growth in Medicare per beneficiary spending between 2007 and 2013, by county; and the extent to which geographic variation in Medicare per beneficiary spending has increased or decreased over time. The analysis finds that beneficiaries living in counties with relatively high Medicare per beneficiary spending tend to be sicker and poorer than beneficiaries living in lower-spending counties and that the gap between high and low-spending counties narrows but does not close after adjustments are made for differences in prices and beneficiaries’ health status. The analysis also shows that the amount of variation between the highest- and lowest-spending counties appears to have narrowed in recent years, raising questions as to whether these changes are due to specific shifts in payment policy. An interactive U.S. map showing county-level Medicare spending is also available.
