Medicare 2027: The BIG Changes You Need to Know Now

A lot of people think Medicare is set-it-and-forget-it. Newsflash: Medicare is not a rotisserie chicken, and 2027 is going to prove that all over again.

A JAMA study estimated that about 2.9 million people in individual Medicare Advantage HMO and PPO plans faced a forced move going into 2026 because their plan left. For 2027, my current estimate is another 2 to 3 million people when all the exits and pullbacks are counted. That’s my estimate, not an official count.

And Medicare Advantage is only half the story. If you have a Medicare Supplement and a separate drug plan, keep reading, because Part D may be the biggest surprise of 2027.

I spent more than two decades working inside Medicare insurance companies, and I still hear a lot before it reaches the average consumer. Some of this is already public. Some is what I’m hearing inside the industry. I’ll tell you which is which.

Key Takeaways

• Plans are disappearing again. If your Medicare Advantage plan leaves your county, you’ll get a letter. Miss it and you could end up with no coverage you planned on.
• Plan ending can open a door. You may get a time-limited right to buy certain Medicare Supplement policies without health questions. Keep your termination letter.
• Standalone Part D is under pressure. Fewer plans, and I expect premium sticker shock for some people.
• Some Medicare Advantage plans can cap enrollment even while Annual Enrollment is open.
• Your agent may not show every plan, and your hospital can leave a network even if your plan stays.
• Same plan name, worse benefits is a real possibility. Read your Annual Notice of Change.

What’s confirmed, and what’s my estimate

Change #1: Medicare Advantage Plans Are Disappearing Again

The industry calls these pullbacks Service Area Reductions, or SARs. Here’s what it means to you: your insurance company says, “We’re not offering your plan where you live anymore.” Not changing it. Not tweaking it. Gone.

The numbers so far:

• One national carrier has publicly said its 2027 exits will affect roughly 600,000 members.
• Early broker reporting in September suggested another large carrier dropped about 13% of its Medicare Advantage plan offerings across 18 states for 2027. That’s plan offerings, not 13% of its members, and the carrier declined to comment.
• I’m also hearing about significant disruption in some rural areas and parts of the Northeast and Midwest.

If your plan disappears, you aren’t losing Medicare, but you do have to make a new coverage decision. If you don’t enroll in another Medicare Advantage plan, you generally return to Original Medicare Parts A and B. That does not automatically replace your drug coverage. You have to enroll in another Medicare Advantage plan with drug coverage or a standalone Part D plan. See our guide to what to do when your plan ends.

The silver lining. If your plan leaves and you return to Original Medicare, you may have a guaranteed-issue right to buy certain Medicare Supplement policies. That means a Supplement company can’t turn you down for your health during the protected window. Maybe you chose Medicare Advantage years ago and your health has changed since. This can open a door that wasn’t open before.

It’s temporary. The federal window generally begins 60 days before your Medicare Advantage coverage ends and runs no more than 63 days after it ends. Keep your termination letter, because you may need to send it to the Supplement company. A new Medicare Advantage plan may still be the better fit. I’d just want to see both choices. See the Medigap birthday rule and the special enrollment period after termination.

Matt’s tip: Don’t only ask which Medicare Advantage plan replaces yours. Ask, “Does this give me a guaranteed-issue opportunity to buy a Medicare Supplement?”

Change #2: Get Ready for Standalone Part D Sticker Shock

If you have Original Medicare, a Medicare Supplement and a standalone Part D plan, this one is for you.

Fewer choices. The average person with Medicare had 14 standalone drug plans to pick from in 2025 and 11 in 2026.

The cushion is gone. A temporary federal program began in 2025 to hold down standalone Part D premiums. It ends after 2026.

A signal of pressure. The national base beneficiary premium, which is used to calculate Part D late-enrollment penalties, rises from $38.99 in 2026 to $41.33 in 2027. That’s not your plan premium, but it points the same direction.

What I expect: some people with standalone drug plans will see monthly premium sticker shock unlike anything in recent years. That’s my expectation based on what I’m seeing, not a published figure.

Premium is just the first place to look. A deductible can rise. A fixed copay can become coinsurance (25% sounds harmless until you ask, 25% of what?). A drug can move to a different tier, a preferred pharmacy can change and the formulary can change.

So don’t shop Part D by premium alone. Shop your drugs. Go to Medicare.gov, enter your actual prescriptions, dosages and the pharmacies you’re willing to use, then compare the estimated annual cost. A plan that costs $20 more a month is $240 more a year. If your drugs are estimated to cost $600 less at the pharmacy, that higher-premium plan could leave you $360 ahead. Assuming the estimates hold.

There is good news too: Medicare-negotiated prices for another 15 high-cost drugs take effect January 1, 2027. Whether that helps depends on whether you take one of them.

Standalone Part D-only shopping is not a Brickhouse Agency service. If all you need is another drug plan, Medicare.gov is a good place to start. Many standalone plans pay agents little or nothing, so don’t assume someone will call you every year to run this review.

Turning 65 or retiring in 2027? The Supplement plus Part D package you price today may cost noticeably more than what a friend or coworker remembers paying. That brings up a bigger question.

Change #3: Part D Costs May Push People Toward Medicare Advantage at a Strange Time

Say your drug-plan premium jumps. You look at a Medicare Advantage plan with drug coverage built in and a low or $0 additional premium and ask, “Why am I paying for a Supplement and a separate drug plan?” Fair question. For some people, Medicare Advantage may be the better fit.

But a drug-plan problem isn’t automatically a reason to replace your medical coverage. And here’s the collision: people used to the broad access of Original Medicare plus a Supplement often look for a Medicare Advantage PPO because it generally offers more provider flexibility than an HMO. PPOs are exactly where we saw some of the heaviest disruption in the big 2026 termination wave, and smaller and rural markets were hit extra hard.

Before you switch, compare doctors, hospitals, prescriptions, the medical maximum out-of-pocket, travel and out-of-area coverage, prior authorization rules, and what your options are if you want a Supplement again later. A PPO is not a Medicare Supplement with a lower price tag. It’s a completely different structure. Our guide on why the MOOP is important is a good place to start.

Matt’s tip: Don’t solve a drug-plan problem by accidentally creating a medical-coverage problem.

Change #4: Some Medicare Advantage Plans Can Cap Enrollment

This is new enough that most people don’t know it exists. For 2027, Medicare Advantage companies can use a new process to get approval for enrollment limits on individual plans. Once the approved capacity is reached, the plan can stop accepting new members, even while Annual Enrollment is open.

To be clear: Annual Enrollment doesn’t close early, and not every plan has a cap. But a shopping window can be open while the plan you wanted is not. If your plan is ending or you know you need to switch, don’t wait until the first week of December. Start early, then confirm the plan you want is still accepting members.

Change #5: Your Agent May Not Show You Every Plan

Some Medicare Advantage plans are becoming non-commissionable again. The plan still exists and still accepts members, but the insurance company has stopped paying an agent to enroll people into it. Standalone Part D has been non-commissionable for most carriers for some time.

That doesn’t mean your agent is doing anything wrong. The carrier made the compensation decision. It does mean the plans your independent agent works with may not be every plan where you live. Ask, “Are there plans available here that your agency doesn’t represent?” and cross-check your area’s full list on Medicare.gov. Know what your source represents.

Change #6: Your Plan Can Stay and Your Hospital Can Leave

Hospitals and health systems around the country are dropping selected Medicare Advantage contracts. One industry tracker counted 29 health systems with announced or implemented Medicare Advantage contract breaks in 2026, after 40 in 2025. It’s a multi-year trend.

One public example: a Florida health system announced that its hospitals and physicians will be out of network with affected Medicare Advantage plans from one national carrier starting January 1, 2027, while that carrier’s Medicare Supplement coverage is not affected. Same company name, very different result depending on your coverage.

If you have a cardiologist, oncologist, surgeon or major hospital system you care about, check the exact plan, not just the carrier name. Check with the plan and with the provider’s billing office. If you’re in active treatment, ask about continuity-of-care protections before canceling appointments. A dental allowance is nice, but dental allowances don’t perform your hip replacement. Use the Medicare provider search to start.

Matt’s tip: A plan renewal doesn’t guarantee a provider renewal. Check both.

Change #7: Even If Your Plan Stays, the Benefits May Get Worse

This may affect more members than outright plan terminations. The plan name can stay the same and the premium can even stay the same while other things move: specialist copays, big up-front medical deductibles, hospital costs, maximum out-of-pocket limits, Part B givebacks, dental, vision, hearing, over-the-counter allowances, prior authorization and the Part D benefit inside the plan. Early reporting from insurance agent publications points to significant benefit reductions at some of the largest carriers.

A $0 premium can still sit on top of higher costs when you actually use care. Your Annual Notice of Change is where to start. Look at what you actually use: premium, specialist and hospital costs, maximum out-of-pocket, drug deductible, prescriptions and any Part B giveback. Then separately verify your doctors and hospitals. Here’s how to read your ANOC. If everything still works, stay put. This isn’t a video telling everybody to switch every year. It’s telling you not to assume the same plan name means the same coverage.

Why Is All of This Happening?

The short version is margin over membership. Medical costs went up and people used more healthcare. Some Medicare Advantage plans stopped producing the profits insurers wanted. So carriers cut benefits, changed networks, made plans non-commissionable, exited counties, shut plans down and, now, are putting limits on how many people they’ll accept. Insurance companies are getting pickier about which Medicare business they want. You need to get pickier about which Medicare coverage you buy.

What To Do Next

• Your Medicare Advantage plan is ending: Don’t panic and don’t automatically take the closest replacement. Check whether you have guaranteed-issue Medicare Supplement rights. Compare your Medicare Advantage alternatives. Make sure your drug coverage continues. Start early.
• Your plan is staying: Read the changes. Check doctors, hospital, drugs and maximum out-of-pocket. If it still works, staying put may be the right answer. See how Star Ratings fit in.
• Original Medicare plus a Supplement plus standalone Part D: Brace for a drug-plan premium review. If your plan stays but gets expensive, shop Part D on Medicare.gov. If your drug plan exits, you need replacement drug coverage. Don’t change your medical coverage because one drug premium made you angry.
• New to Medicare in 2027: Forget what your neighbor pays. Build your decision on the market that exists where you live today: doctors, hospitals, prescriptions, premiums, your financial exposure, travel, and whether the choice may be harder to reverse later. Compare enrollment period types too.

If this has become a real overall Medicare coverage decision, a good independent Medicare agent can help. Brickhouse Agency, a boutique independent agency, helps people compare Medicare Advantage and Medicare Supplement options, including plan terminations, provider-network changes and first-time Medicare decisions. Appointments are by phone or Zoom and are education-first, with no obligation to enroll. Schedule your free consultation.

One reminder: Brickhouse does not take standalone Part D-only shopping appointments. If all you need is another drug plan, Medicare.gov is a good place to start.
