Medicare Advantage Plans 2027: 4.3 Million People Are Losing Their Plan. Is Yours Ending?

KFF, a nonprofit health policy research group, reviewed federal plan data for next year. It found about 4.3 million beneficiaries are in a Medicare Advantage plan or stand-alone Part D drug plan that will not be offered in 2027.

Of the 3.1 million Medicare Advantage members losing a plan, about 2.8 million are in plans open to anyone. That is roughly 14% of people in those plans, up from 13% a year ago. About 300,000 more are in special needs plans.

Drug plans changed even more. About 6% of stand-alone Part D members are affected, double last year’s share. The biggest closure is CVS’s SilverScript Choice, with about 950,000 members, followed by HealthSpring Extra Rx at about 190,000. The typical person will have 9 stand-alone drug plans for 2027, down from 11.

Four parent companies account for about half of people losing a Medicare Advantage drug plan open to the general public.

These companies are not leaving Medicare. Each still sells plans for 2027 in many areas, but it is closing specific plans or leaving certain counties, so your neighbor’s plan may be fine while yours ends. For carrier details, see is Humana leaving Medicare Advantage in 2027 and is Aetna leaving Medicare Advantage in 2027.

Not every change is a full shutdown. Your letter says which of these is happening, and it affects your rights.

If your plan is being merged, read the Annual Notice of Change. Premiums, copays, the network and the drug list can all be different, and you can still switch during Annual Enrollment.

If your Medicare Advantage plan is terminated and you choose nothing, you still have Medicare. On January 1, 2027 you go back to Original Medicare, Part A and Part B.

If your stand-alone Part D plan is the one ending, your drug coverage stops on December 31 unless you pick a new drug plan or join a Medicare Advantage plan that includes drugs.

You have more than one chance to act, but picking a plan by December 7 means new coverage starts January 1 with no gap.

You can apply for Medigap as early as 60 days before your old plan ends. Enrolling during the special period after January 1 generally starts coverage the first of the next month, which can leave a short gap.

Plans are sold by county, so the only list that counts is the one for your ZIP code. Search the Medicare Plan Finder at Medicare.gov or compare options with a licensed agent, and have your drug list ready.

Look closely at extras this year. Many insurers are trimming them, and Medicare Advantage plans 2027 may include dental, vision, hearing or over-the-counter allowances depending on the plan and area. Not all plans offer all benefits, so confirm amounts in each Summary of Benefits. The national average premium for 2027 is projected at $12.00 a month, down from $14.37.

Comparing Medicare Advantage plans 2027 side by side is the best way to avoid a surprise in January. Focus on what you would pay in a bad year, not only the premium.
