Your Medicare Plan Is Leaving Your Area? Your Options and Deadlines.
If your Medicare Advantage plan is not renewing, or the insurer is pulling out of your county, you do not lose Medicare. You keep your current plan through December 31, and you get special windows to pick new coverage. The main thing to avoid is doing nothing and ending up without a drug plan. Here is what your notice means, your deadlines, and how to choose what comes next.
Free. We explain your notice in plain language, no plan sales.
What "leaving your area" or "not renewing" means
Every year some Medicare Advantage plans change where they operate. Two things can happen to your plan:
- A service-area reduction: the insurer stops offering your plan in your county, even if it keeps the plan elsewhere.
- A non-renewal or termination: the plan is ending entirely and will not continue next year.
Either way, you should receive a written notice, usually in early October, telling you the plan will not continue and that you need to choose new coverage. Your current plan keeps working normally through December 31. Nothing changes mid-year.
What happens if you do nothing
If your Medicare Advantage plan ends and you take no action, you generally fall back to Original Medicare (Part A and Part B) on January 1. That keeps your hospital and medical coverage, but it does not include drug coverage.
Your enrollment windows and deadlines
Special Enrollment Period (because your plan is ending)
When a plan is non-renewed, terminated, or reduces its service area, you get a Special Enrollment Period that generally runs from December 8 to the end of February to enroll in a new Medicare Advantage or Part D plan. This is your safety net if you miss the fall window.
Annual Enrollment Period (open to everyone)
From October 15 to December 7, anyone can switch a Medicare Advantage or Part D plan, with coverage effective January 1. If you choose here, your new coverage starts the day after your old plan ends, with no gap.
Medicare Advantage Open Enrollment Period
From January 1 to March 31, someone already in a Medicare Advantage plan can switch to one other Medicare Advantage plan or return to Original Medicare with a Part D plan, one time. This is separate from the Special Enrollment Period above, so you may have more than one window available.
Dates can depend on your exact situation. Confirm the window that applies to you with your plan or 1-800-MEDICARE (1-800-633-4227).
Your Medigap guaranteed-issue right
If you want to go back to Original Medicare, a Medigap (Medicare Supplement) policy can help cover your out-of-pocket costs. Normally insurers can screen your health before selling you one. But when your Medicare Advantage plan leaves your area or you involuntarily lose coverage, you generally have a guaranteed-issue right: you can buy certain Medigap policies without medical underwriting, meaning no health questions and no being turned down for a health condition.
How to choose replacement coverage
There is no single right answer, and we never recommend a specific plan or insurer. The right choice depends on your own doctors, your medications, and your budget. A good way to work through it:
Read your notice so you know exactly what is ending and when. If it is confusing, the free Medicare Letter Check tool will explain it in plain language.
Decide the shape of coverage you want: another Medicare Advantage plan, or Original Medicare plus a Part D drug plan (and possibly a Medigap policy).
Check that your doctors and prescriptions are covered before you enroll, and confirm the deadline that applies to you.
Not sure what your letter is telling you?
Upload your Medicare notice and our free Medicare Letter Check tool will explain what it means, what is ending, and the deadlines you need to watch. CareRoute is independent, does not sell insurance, and takes no commissions, so the explanation is on your side. If you want help weighing which coverage fits your own doctors and drugs, Decision Support can walk you through the trade-offs.
Frequently asked questions
My Medicare Advantage plan says it is leaving my area or not renewing. What does that mean?
It means the plan is ending in your county for next year, either because the insurer is pulling out of your service area (a service-area reduction) or is not renewing the plan at all (a non-renewal or termination). You will get a notice, usually in early October, telling you your plan will not continue and that you need to choose new coverage. Your current plan keeps working through December 31.
What happens if I do nothing?
If your Medicare Advantage plan ends and you take no action, you generally return to Original Medicare (Part A and Part B). The catch is drug coverage: you will not have a Part D drug plan unless you enroll in one. That can leave a gap in drug coverage and, if you go 63 days or more without creditable drug coverage, a permanent Part D late enrollment penalty. Doing nothing is rarely the best choice.
When can I enroll in a new plan, and what is the deadline?
When a plan is non-renewed, terminated, or reduces its service area, you get a Special Enrollment Period that generally runs from December 8 to the end of February to enroll in a new Medicare Advantage or Part D plan. You can also use the Annual Enrollment Period, October 15 to December 7, when anyone can switch a Medicare Advantage or Part D plan for coverage effective January 1. Confirm the exact dates that apply to your situation with your plan or 1-800-MEDICARE.
Can I buy a Medigap policy without medical underwriting?
Often, yes. When your Medicare Advantage plan leaves your area or you involuntarily lose coverage, you generally have a guaranteed-issue right to buy certain Medigap (Medicare Supplement) policies without answering health questions or being turned down for a health condition. This right is time limited, usually within 63 days of your coverage ending, so act promptly if you want to return to Original Medicare with a Medigap policy.
Should I switch to another Medicare Advantage plan or go back to Original Medicare?
That depends on your doctors, your medications, and your budget, and it is a personal decision. We do not recommend any specific plan or insurer. If you want help comparing how the options line up with your own doctors and drugs, CareRoute Decision Support can walk you through the trade-offs. If you just want to understand what your letter means, the free Medicare Letter Check tool will explain your notice.
I already had a Medicare Advantage plan. Can I still use the Medicare Advantage Open Enrollment Period?
The Medicare Advantage Open Enrollment Period runs January 1 to March 31 and lets someone already enrolled in a Medicare Advantage plan switch to one other Medicare Advantage plan or return to Original Medicare with a Part D plan, one time. It is separate from the Special Enrollment Period you get when your plan leaves your area, so you may have more than one window available. Confirm which one fits your situation before you act.
