The Medicare prescription drug program – Part D – is loved by beneficiaries for consistently delivering low premiums, robust choices, and broad access to drugs. The Inflation Reduction Act (IRA) radically rewrote Part D, imposing price controls on drugs while redesigning drug coverage in a way that is increasing premiums, reducing competition and choice, and raising out-of-pocket costs.

Seniors Facing High Premiums

Seniors are facing the highest premiums in Medicare Part D’s history with the fewest number of available plans.

The IRA was supposed to cap premiums at a 6% increase per year, but premiums increased an average of 21% in 2024. In 2025, premiums are estimated to increase anywhere from 50-100% or higher.

IRA Impact on
Part D

A new report by the Council for Affordable Health Coverage tracks how the IRA’s redesign of Part D is impacting the benefit.
