Medicare Advantage Is Cutting Benefits and Exiting Markets for 2027: What to Do Before December 7

If you have a Medicare Advantage plan, the coverage you have this year may not look the same in 2027, and in some counties it may not be offered at all. Insurers are pulling out of markets they no longer find profitable and paring back the extra benefits that drew people to these plans in the first place. Humana, one of the two largest Medicare Advantage insurers, told investors in July that its 2027 market exits alone would affect roughly 600,000 members.

The part that matters for your own coverage is this: if your plan is changing or going away, you are not stuck. Medicare builds in a set of rights and deadlines for exactly this situation. What follows sorts out what is actually settled for 2027 from what insurers are only signaling, and lays out what to do before Open Enrollment closes on December 7.

What is confirmed for 2027

Open Enrollment runs from October 15 to December 7, 2026, and any change you make takes effect January 1, 2027. That is the window to switch plans, move between Medicare Advantage and Original Medicare, or change your drug coverage. By September 30, your plan had to mail you an Annual Notice of Change, the document that lists every adjustment to your premium, copays, drug list, and provider network for next year. If your plan is being discontinued, you also get a separate non-renewal notice.

On the money side, the federal government is paying Medicare Advantage insurers more next year, not less. In its final 2027 rate announcement on April 6, 2026, the Centers for Medicare and Medicaid Services set a net payment increase averaging 2.48 percent, or more than $13 billion. Counting the way insurers code enrollees' health, the government's own estimate of the total increase is closer to 5 percent. Insurers argue that other recent changes to how they are paid still leave them squeezed, and they are trimming and reshuffling plans as a result.

Whole plans are leaving some areas

The plainest change is that there are fewer plans to choose from than a couple of years ago. According to KFF, the average Medicare beneficiary could pick from 32 Medicare Advantage drug plans for 2026, down from 34 the year before and a peak of 36 in 2024. About 3,373 plans were offered nationwide for 2026, a 9 percent drop from the prior year.

Plan terminations climbed alongside that. KFF found that about 2.6 million people, or 13 percent of those in Medicare Advantage drug plans, were in a plan that was discontinued for 2026, up from about 1.3 million, or 6 percent, the year before. Early signs point to more of the same for 2027. Humana said its planned exits would affect about 600,000 of its 7.2 million members, roughly 8 percent, though it expects to move about 240,000 of them into its other plans.

Benefits are getting leaner

For years, Medicare Advantage plans competed by piling on extras: dental, vision, hearing, over-the-counter allowances, gym memberships, even money back on the Part B premium. That growth has stalled. Virtually all plans still include some dental, vision, and hearing coverage, but insurers and brokers say the richer perks are being trimmed for 2027. Reported targets include the Part B giveback that refunds part of your premium, dental allowances, and higher copays for specialist visits.

A caution on that last point: broad benefit reductions are what insurers and analysts expect, not a single official figure you can look up. The only way to know what is happening to your plan is to read your own Annual Notice of Change. CMS also loosened a few consumer protections for 2027. It dropped a requirement, added only recently, that plans send a mid-year notice reminding you which supplemental benefits you had not used, and it removed some marketing rules, including a ban on superlatives in plan advertising.

If your plan is leaving, you have extra rights

Losing your plan is not the same as losing coverage, and it comes with protections most people never hear about. If your Medicare Advantage plan is not renewed, you get a Special Enrollment Period that runs from December 8 through the last day of February to pick a new plan. If you do nothing, you are moved to Original Medicare, so you are not left uninsured.

There is a second right that is easy to miss and can be worth real money. When your Medicare Advantage plan leaves Medicare or stops serving your area, you get a guaranteed issue right to buy a Medigap policy if you go back to Original Medicare. That means an insurer must sell you certain Medigap plans and cannot charge you more or turn you down because of your health, which is not true at most other times. You can apply as early as 60 days before your plan ends and no later than 63 days after it ends, so do not let that window pass.

What to do before December 7

Start with the Annual Notice of Change your plan mailed by September 30, and read it even if you like your plan. Then use the Plan Finder at Medicare.gov, which lets you enter your drugs and pharmacy and estimates your full yearly cost for each plan in your area, not just the premium. Our guide to Medicare Open Enrollment for 2027 walks through comparing plans step by step.

If cost is the real problem, check whether you qualify for help before you settle for a thinner plan. Medicare Savings Programs and Extra Help can cover your Part B premium and lower your drug costs, and Medicare's first negotiated drug prices have brought down the cost of ten widely used medications for 2026. A plan with fewer frills may still work if these programs fill the gaps.

The bottom line for 2027 is that Medicare Advantage is not disappearing, but it is getting choosier and, for a lot of people, less generous. That makes this Open Enrollment more important than usual. Read your notice, compare your real costs, and if your plan is leaving, remember that you have both a special enrollment window and a rare chance to buy Medigap without a health review. Doing nothing is the option most likely to cost you next year.
