Medicare Advantage Termination Letters: Your 2027 Options

Have you received a letter saying your Medicare Advantage coverage will end? If so, you’re not alone. If your plan won’t renew for 2027, the letter should tell you when your current coverage ends and what you can do next. For a plan ending at the close of 2026, that usually means December 31, 2026.

Don’t worry. This guide explains what a Medicare Advantage termination letter means, the deadlines to watch, and whether another Medicare Advantage plan or Original Medicare with Medigap might be a better fit for you.

What Exactly Is a Medicare Advantage Termination Letter?

A termination or non-renewal notice is your carrier’s official way of saying:
“This Medicare Advantage plan won’t be offered anymore starting in 2027.”

When you get one, it usually includes:

• A clear statement that your current MA plan won’t continue in 2027
• The date it ends (usually December 31, 2026)
• Your rights and next steps — like whether you qualify for a Special Enrollment Period
• Suggestions for alternative coverage — possibly another MA plan the carrier offers, or going back to Original Medicare with Medigap

This is different from an Annual Notice of Change, which explains next year’s costs and benefits for a continuing plan. It’s also different from a notice that a particular medical service will no longer be covered. Read the letter carefully to see whether your whole plan is ending, your county is being dropped, or you’re being moved into another plan.

What Your Letter Might Say

The examples below are illustrations, not quotes from an insurer or official notices. Your letter’s dates and instructions matter.

Example 1:

“We regret to inform you that we will not renew your Medicare Advantage HMO plan in 2027. Your current coverage will end on December 31, 2026. You may choose another Medicare Advantage plan in your service area or return to Original Medicare with the option to purchase a Medigap policy. Please review your options and act before the deadline to avoid a gap in coverage.”

Example 2:

“Your Medicare Advantage PPO plan will not be available after December 31, 2026. If you don’t join another Medicare Advantage plan before your current plan ends, you’ll return to Original Medicare beginning January 1, 2027. You’ll need to arrange separate Part D coverage if you want Medicare prescription drug coverage. If you’re considering Medigap, check your guaranteed-issue rights and application deadline.”

Example 3:

“Important Notice: We are writing to notify you that the Medicare Advantage Special Needs Plan (SNP) you are enrolled in will not be renewed for 2027. Coverage under this plan will terminate on December 31, 2026. You qualify for a Special Enrollment Period and may join another Medicare Advantage plan, including a different SNP if eligible, or return to Original Medicare. Please act promptly to avoid losing prescription drug coverage.”

Tip: Don’t Toss It Out

Save this termination or non-renewal notice — even if it looks like junk mail. It can help document your right to a Special Enrollment Period and certain Medigap protections. Hold onto it, and keep a copy of any enrollment confirmations, too. Keeping the letter alone doesn’t prevent a Part D late enrollment penalty; getting your drug coverage lined up on time matters.

Insurance companies don’t send out non-renewal notices just for fun.

Here are some of the most common reasons:

• They’re shrinking or rearranging service areas — maybe they no longer can maintain provider networks in certain rural or less populated counties.
• Some plans have had low enrollment, making them financially unsustainable.
• Costs have gone up — prescription drugs, provider fees, hospital charges — and insurers may decide to eliminate certain benefit designs or whole plan types.
• Consolidation moves: a carrier may want to simplify its offerings by shutting down one plan and guiding members into another.

Whatever the reason, you are entitled to notice and time to pick something new.

Here are the key dates if your current plan ends December 31, 2026 and won’t renew for 2027:

• Fall 2026: Watch for your plan’s official non-renewal notice. CMS lists these notices in October, generally by October 2. Don’t confuse it with the Annual Notice of Change you normally get in September.
• October 15–December 7, 2026: Annual Enrollment Period (AEP). Compare 2027 Medicare Advantage and Part D plans and enroll for coverage starting January 1, 2027.
• December 31, 2026: Your current plan’s last day of coverage, if that’s the end date in your notice.
• December 8, 2026–February 28, 2027: The Special Enrollment Period for a plan whose contract isn’t renewed gives you another chance to join a Medicare Advantage or Part D plan. Confirm when your new coverage will start before you enroll.
• January 1, 2027: If your plan ends and you haven’t joined another Medicare Advantage plan, you’ll generally return to Original Medicare. Separate Part D coverage and Medigap aren’t automatically added.

Don’t use that February deadline as a reason to put this off. Getting your new coverage lined up before your old plan ends can help you avoid a break in drug coverage or unexpected costs. If your letter describes a midyear termination rather than a year-end non-renewal, different enrollment dates can apply. Follow the notice and confirm your window with Medicare or a licensed insurance agent.

When a notice says your Medicare Advantage plan won’t renew for 2027, you essentially have two paths forward. Each has trade-offs. Let’s compare.

What’s good:

• Often lower monthly premiums than Medigap policies.
• Extra benefits — vision, dental, hearing, fitness — that Original Medicare doesn’t cover.
• Medicare Advantage plans have a yearly out-of-pocket limit for covered Part A and Part B services. Prescription drug costs have separate rules.

What to watch out for:

• Limited provider networks, especially if you travel or have doctors outside the network.
• Benefits/costs may change each year — what looks good now might not next year.
• Switching plans could mean losing your existing provider relationships if they’re out of network.

(Carriers may suggest you move into another plan they offer. That might feel easy — but feel free to shop around. Another carrier might offer a better deal for your doctors, prescriptions, or cost preferences.)

What’s good:

• You generally have access to any doctor or hospital that accepts Medicare. No network restrictions.
• Standardized Medigap benefits are more predictable, though premiums can rise.
• Strong protection for unexpected medical events, especially hospitalizations or surgeries.

What’s harder:

• Higher premiums — you’ll typically pay more monthly than many Medicare Advantage plans.
• Medigap doesn’t cover prescription drugs. You’ll generally need a separate Part D plan unless you have other creditable drug coverage.
• If your Medicare Advantage plan leaves Medicare or stops serving your area, you may have guaranteed-issue rights to certain Medigap policies. That means you can buy an eligible policy without medical underwriting. The available policies depend on your eligibility and state rules.

Check the Medigap deadline separately. In a qualifying plan-loss situation, you can generally apply starting 60 days before your Medicare Advantage coverage ends and no later than 63 days afterward. Keep your non-renewal letter as proof and confirm your rights, available policies, and effective date before making a switch. State protections may give you additional options. Medigap works with Original Medicare; it doesn’t replace it or work alongside Medicare Advantage.

Here’s a game-plan to help things go smoothly:

1. Read your termination letter carefully. Highlight the deadlines so you don’t make a mistake and miss it.
2. Make a list of your doctors, hospitals, and all your current medications. Compare new plans based on what you actually use.
3. Use Medicare’s Plan Finder tool early to see what MA and Part D options exist in your ZIP code.
4. Book a free consultation to compare your options — not just the plan suggested by the carrier canceling your coverage. Bring your letter, doctors, medications, and preferred pharmacy.
5. Don’t wait until the last minute. Even though the non-renewal SEP runs through February 28, 2027, aim to have your replacement coverage ready for January 1. Confirm the start dates for your health coverage, Part D plan, and Medigap policy, if you’re buying one.

If your plan ends on December 31, 2026, and you haven’t joined another Medicare Advantage plan, you’ll generally return to Original Medicare on January 1, 2027. Check your letter for any instructions about being moved into another plan, especially if you receive Extra Help.

But heads up: Original Medicare doesn’t automatically replace your plan’s prescription drug coverage or add a Medigap policy.

Original Medicare covers eligible Part A and Part B services, but it doesn’t have a yearly out-of-pocket limit. Without supplemental coverage, those costs can add up.

You’ll also need to line up a separate Part D plan unless you have other creditable prescription drug coverage. Going 63 days or more without either may lead to a Part D late enrollment penalty.

Don’t leave this to chance. Keep your letter, review your options, and confirm when your new coverage starts. If you need a hand, book a free Medicare consultation.

Monthly Premiums

• Medicare Advantage: Often lower monthly premiums; some plans have a $0 plan premium. You still pay your Part B premium.

• Original Medicare + Medigap: Typically higher monthly premiums, since you pay for Part B, Medigap, and a separate Part D plan.

Doctor/Hospital Flexibility

• Medicare Advantage: Provider access depends on the plan’s network and rules. PPOs may cover out-of-network care at a higher cost.

• Original Medicare + Medigap: You can generally see any doctor or hospital that accepts Medicare.

Extra Benefits

• Medicare Advantage: May include dental, vision, hearing, and fitness benefits. Coverage varies by plan.

• Original Medicare + Medigap: These extras generally aren’t included. You may need separate coverage.

Out-of-Pocket Costs

• Medicare Advantage: Plans have a yearly out-of-pocket limit for covered Part A and Part B services. Prescription drug costs are separate.

• Original Medicare + Medigap: Medigap helps pay certain costs Original Medicare leaves behind. What you pay depends on the policy you choose.

Yearly Stability

• Medicare Advantage: Benefits, networks, and costs can change each year.

• Original Medicare + Medigap: Standardized Medigap benefits are more predictable, but premiums and Part D coverage can change.

A Medicare Advantage termination letter may feel unnerving — but you do have control. Once you understand why your plan is ending, when it stops, and what your 2027 options are, you can make a plan.

Don’t let the notice intimidate you. Keep the letter, compare your choices, and get your new coverage lined up before your current plan ends.
