Your Medicare Advantage Plan Is Ending? Here Is Exactly What to Do.
First, take a breath. If your Medicare Advantage plan is ending or discontinued, you do not lose your Medicare. You get a Special Enrollment Period to choose new coverage, and you can either join a different Medicare Advantage plan or return to Original Medicare with a Part D drug plan (and, if you want, a Medigap policy). Below is why plans end, the deadlines that matter, and the step-by-step.

Why Medicare Advantage plans end or get discontinued
Medicare Advantage plans are private contracts that insurers renew with Medicare each year. Sometimes an insurer decides to leave a county or state, stop offering a particular plan, or the plan's contract with Medicare is not renewed. This is a business decision by the insurer. It is not a reflection on you or your health, and it does not mean you did anything wrong.
If your plan is ending, you will get a written notice, often called a non-renewal, plan termination, or service area reduction letter. It tells you when your current coverage stops and what your options are. The key thing to understand: your Medicare stays. Only this specific plan is going away.
The enrollment periods and deadlines that apply
When a plan is ending, timing matters. Here are the windows that can apply to you.
Special Enrollment Period (SEP) for a plan that is ending
If your plan is non-renewing, terminating, or leaving its service area, you generally get a Special Enrollment Period that runs December 8 through the end of February to enroll in a new plan. This is the window created specifically because your plan is going away.
Annual Election Period (AEP): October 15 to December 7
Every year, anyone with Medicare can switch Medicare Advantage or Part D plans during this window. Changes you make take effect January 1. If your plan is ending, this is often the cleanest time to line up your new coverage so there is no gap.
Medicare Advantage Open Enrollment Period (MA OEP): January 1 to March 31
If you are in a Medicare Advantage plan, this window lets you switch to one other Medicare Advantage plan, or return to Original Medicare and add a Part D drug plan (once during the period). It is a useful backstop if you want to change course early in the year.
The exact dates and which window applies depend on your situation. Confirm with your plan or 1-800-MEDICARE (1-800-633-4227), or upload your letter and we will explain what applies to you.
Step by step: what to do now
Read your notice and find the date your current coverage ends. Do not throw the letter away, it names your plan, the reason it is ending, and your options.
Decide the core choice: another Medicare Advantage plan, or Original Medicare plus a Part D drug plan (and, if you want predictable costs, a Medigap policy).
Before you pick, verify your doctors are in the new plan’s network and your medications are on its drug list (formulary) and affordable. Networks and formularies change every year.
Enroll during your window (the Special Enrollment Period, or the Annual Election Period from October 15 to December 7) so there is no gap in coverage on January 1.
Make sure you have drug coverage the whole time. Going 63 days or more without creditable drug coverage can trigger a permanent Part D late enrollment penalty.
Original Medicare plus Medigap is a real option, not just another Advantage plan
When a plan ends, it is easy to assume the only move is to hop to another Medicare Advantage plan. It is not. The core choice is between a Medicare Advantage plan and Original Medicare plus a Part D drug plan, optionally with a Medigap (Medicare Supplement) policy to help with out-of-pocket costs.
- When your Medicare Advantage plan leaves your area or you involuntarily lose the coverage, you generally have a guaranteed-issue right to buy certain Medigap policies without medical underwriting, usually within 63 days of your coverage ending.
- Trial right: if you joined Medicare Advantage when you were first eligible for Medicare and you switch back to Original Medicare within 12 months, you have a guaranteed Medigap right.
- Guaranteed issue matters because it means an insurer generally cannot deny you a Medigap policy or charge you more based on your health, but the window is time-limited, so do not let it lapse.
Which path fits you depends on your doctors, your medications, and your budget. We do not recommend a specific plan or insurer. If you want that comparison done for you, that is what Decision Support is for.
Want to know which plan fits your doctors and drugs?

Frequently asked questions
My Medicare Advantage plan is ending. Will I lose Medicare?
No. Your Medicare itself does not go away. When a Medicare Advantage plan stops (it is non-renewing, leaving your area, or the contract is terminating), you keep your Medicare, and you get a Special Enrollment Period to pick new coverage. That period generally runs December 8 through the end of February. You can join a different Medicare Advantage plan, or return to Original Medicare and add a Part D drug plan.
Why do Medicare Advantage plans end or get discontinued?
Plans are private contracts that insurers renew with Medicare each year. A plan can leave a county or state, stop being offered, or have its contract ended. This is a business decision by the insurer and is not a reflection on you or your health. If your plan is ending, you will receive a written notice (often called a non-renewal or plan termination letter) telling you when coverage stops and what your options are.
What is the Special Enrollment Period I get when my plan ends?
When a Medicare Advantage plan is non-renewing, terminating, or leaving its service area, you generally get a Special Enrollment Period (SEP) that runs December 8 through the end of February to enroll in a new plan. This is separate from the regular Annual Election Period (October 15 to December 7). Confirm the exact dates for your situation with your plan or 1-800-MEDICARE (1-800-633-4227).
Can I switch to Original Medicare and a Medigap policy instead of another Advantage plan?
Yes. Returning to Original Medicare, adding a Part D drug plan, and buying a Medicare Supplement (Medigap) policy is a real option, not just another Medicare Advantage plan. When your Medicare Advantage plan leaves your area or you involuntarily lose the coverage, you generally have a guaranteed-issue right to buy certain Medigap policies without medical underwriting, usually within 63 days of your coverage ending. Which plan fits your budget and situation depends on the details, so it is worth reviewing carefully.
Why do I need to check my doctors and drugs before I choose?
Every Medicare Advantage and Part D plan has its own provider network and drug formulary, and they change year to year. Before you enroll, verify that your doctors are in network and that your medications are covered and affordable under the new plan. If you want help comparing which plan fits your specific doctors and drugs, CareRoute Decision Support does that research for you.
What happens if I do nothing?
If your plan is ending and you take no action during your enrollment window, you generally fall back to Original Medicare, but you may be left without Part D drug coverage. Going 63 days or more without creditable drug coverage can trigger a permanent Part D late enrollment penalty, so do not let your drug coverage lapse. Act during your enrollment window rather than waiting.
What does my Medicare notice actually mean?
Notices use terms like non-renewal, plan termination, and service area reduction, and it is not always clear what you need to do or by when. You can upload your letter to the free CareRoute Medicare Letter Check and get a plain-language explanation of what it means and what your options and deadlines are.
