Medicare Part D Plans for 2025: Premium Changes and Enrollment Impact

The Centers for Medicare & Medicaid Services (CMS) recently unveiled details regarding Medicare Part D plans for 2025, noting that while the average premiums are described as stable, many insurers are nonetheless raising their premiums for standalone drug plans. Major health insurers, like Aetna and UnitedHealthcare, are scaling back their offerings of these standalone plans, resulting in a decrease in the total number available nationwide from 709 in 2024 to 524 in 2025. This year's release drew more attention than usual due to uncertainty surrounding changes implemented under the Inflation Reduction Act which aims to cap out-of-pocket drug expenses for beneficiaries. Notably, changes set for 2025 include a $2,000 cap on out-of-pocket spending, alongside increased costs covered by insurers. While these adjustments promise improved financial protection for patients, fears abound that insurers may hike premiums significantly for Part D coverage. Fortunately, the premium increases appear to have been moderated by a Biden-Harris administration program which limits increases to $35 per month. Nonetheless, California data shows varied premium movements among different plans, which could incite shifts in enrollment patterns during the upcoming open enrollment period as beneficiaries assess their options more critically.
