Average Medicare Advantage premiums are expected to decrease

The CMS also announced that average premiums, benefits and plan choices for Medicare Advantage and the Medicare Part D prescription drug program are expected to remain stable in 2025.

According to the CMS, approximately 60% of Medicare Advantage enrollees in their current plan will have a zero-dollar premium in 2025. 

The average monthly plan premium for all Medicare Advantage (MA) plans, which includes MA plans with prescription drug coverage, is expected to decrease by $1.23 from $18.23 in 2024 to $17.00 in 2025. The CMS says that approximately 83% of enrollees will have the same or lower premium in 2025 if they continue in the same plan. 

The average MA plan with prescription drug coverage Part D total premium is projected to decrease from $15.56 in 2024 to $13.50 in 2025 (a decrease of $2.06).

Other changes coming to Medicare Part D in 2025:

1. New $2,000 annual cap on out-of-pocket prescription costs

Beginning in 2025, people with Part D plans won’t have to pay more than $2,000 in out-of-pocket costs, thanks to a provision in the Inflation Reduction Act of 2022. The $2,000 cap will be indexed to the growth in per capita Part D costs, so it may rise each year after 2025.

This new rule applies only to medications covered by your Part D plan and does not apply to out-of-pocket spending on Medicare Part B drugs. Part B drugs are usually vaccinations, injections a doctor administers, and some outpatient prescription drugs.

2. Option to spread their prescription drug costs throughout the year. 

Part D enrollees will also have the option of spreading out their out-of-pocket costs over the year rather than face high out-of-pocket costs in any given month. Part D enrollees who select this payment option will pay $0 to the pharmacy for covered Part D drugs, and Part D plan sponsors will then bill program participants monthly for any cost sharing they incur while in the program.

3. Supplemental Part D benefits count towards individual out-of-pocket costs

People with Medicare enrolled in a Part D plan that offers enhanced supplemental benefits will have the added advantage of these supplemental benefits counting towards their out-of-pocket costs, resulting in their reaching the $2,000 cap for 2025 sooner.   

For instance, drugs that are excluded from the definition of Part D drug, even in cases where the plan chooses to cover them as a supplemental benefit, such as drugs for hair growth.
