Analyses Paint Mixed Picture of Stand-Alone PDP Costs in 2025

Premiums for many stand-alone Medicare Part D Prescription Drug Plans will go up moderately in 2025, while the number of PDP options for beneficiaries will drop significantly, according to AIS Health’s analysis of the recently released CMS Medicare Advantage and Part D landscape files.

The Inflation Reduction Act, passed in 2022, ushered in a host of policy changes to the Part D benefit that will take effect in 2025: Most notably, Medicare Part D beneficiaries’ out-of-pocket drug costs will be capped at $2,000 annually and Part D plan sponsors will be responsible for 60% (up from 20%) of any costs their enrollees incur beyond that cap. As a result, the Medicare Part D national average monthly bid amount (NAMBA) is projected to increase by $115, nearly 180%, to $179.45 in 2025.
