Your Medicare Plan Is No Longer Available Where You Live? Here Is What Is Still Offered in Your County.
If your insurer says your Medicare Advantage plan is no longer available in your area, it usually means the plan is pulling out of your county, not that you are losing Medicare. Medicare plans are sold county by county, so the plans available to you depend on where you live. Below is why an insurer withdraws from an area, the difference between your plan leaving your county and being discontinued everywhere, and how to find the Medicare Advantage, Part D, and Medigap options that are still offered where you live.

Leaving your area is not the same as the plan being discontinued
These two notices sound alike but mean different things, and the difference decides what you can do next:
- The insurer is pulling out of your county (a service-area reduction). The plan can still exist elsewhere; it just is not offered where you live anymore. A similar plan from the same insurer may still be available in a neighboring county, and if you moved there you might be able to keep something close to it.
- The plan is discontinued entirely (a non-renewal or termination). The insurer is ending that plan for everyone, in every county, so there is no version of it to move to.
In both cases you keep Medicare and you get a special window to choose new coverage. But if your plan is only leaving your area, the useful question is not just what to do, it is what is still offered where you live. If you have the notice but are not sure which of these it describes, our free Medicare Letter Check will read it and tell you.
For the personal "my plan was discontinued, what happens now" walkthrough, see Your Medicare Advantage plan is ending. This page focuses on the geographic side: why plans leave a county and what remains available in yours.
Why an insurer withdraws from a county or region
Medicare Advantage and Part D plans are private contracts that insurers file with Medicare one county at a time. Each year an insurer decides which counties it will serve, and it can add or drop counties. When a plan leaves your area, it is a business decision about that market, not a judgment about you or your health. Common reasons an insurer reduces a service area include:
- It could not build or keep an adequate network of local doctors and hospitals in that county.
- The plan was not financially sustainable in that market, or enrollment there was too low.
- The insurer is refocusing on other regions or restructuring which plans it offers where.
You should get a written notice, usually in early October, telling you the plan will not be available in your area next year. Your current plan keeps working normally through December 31. Nothing changes mid-year, and you do not lose Medicare itself.
Plan availability is county by county
The Medicare Advantage and Part D plans you can join are set by your permanent address, right down to the county. Two people a few miles apart can have completely different plan menus. So when one plan leaves your county, the real task is finding what is still offered at your address, not assuming your only choice is gone.
How to find the options still offered in your county
You can see exactly which plans serve your address. We never recommend a specific plan or insurer; the point is to look at your county's real menu and compare it to your own doctors, medications, and budget.
Use the official Medicare Plan Finder at Medicare.gov and enter your ZIP code. It lists every Medicare Advantage and Part D plan available in your county, with premiums, drug coverage, and star ratings.
Check whether each plan covers your doctors (its network) and your medications (its formulary) at your address. Networks and drug lists are set locally and change every year.
If you would rather return to Original Medicare, look at which Medigap (Medicare Supplement) policies are sold in your state, since availability and pricing are set at the state level.
Confirm the enrollment window that applies to you, then enroll. If comparing your county menu is overwhelming, Decision Support can do that research for you for $99.
You can also call 1-800-MEDICARE (1-800-633-4227) or your State Health Insurance Assistance Program (SHIP) for free, unbiased help with your county's options.
If you do nothing, drug coverage is the gap
If your Medicare Advantage plan leaves your area 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, and it will not automatically enroll you in a plan available in your county.
Your enrollment windows, framed around your area
Because your plan is leaving your area, you get an extra window on top of the windows everyone has. In short:
Special Enrollment Period (because your plan is leaving your area)
When a plan reduces its service area or is non-renewed or terminated, you get a Special Enrollment Period that generally runs from December 8 to the end of February to enroll in a plan still offered in your county. This is your safety net if you miss the fall window.
Annual Enrollment Period (open to everyone): October 15 to December 7
Anyone can switch a Medicare Advantage or Part D plan in this window, with coverage effective January 1. If you choose a plan available in your county here, your new coverage starts the day after your old plan ends, with no gap.
Medicare Advantage Open Enrollment Period: January 1 to March 31
If you are already in a Medicare Advantage plan, this window lets you 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 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 when a plan leaves your area
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. Which specific Medigap policies are sold, and at what price, is set at the state level, so check what is available where you live.

Frequently asked questions
My insurer says my Medicare plan is no longer available where I live. What does that mean?
It usually means the insurer is pulling out of your county, called a service-area reduction. The plan may still exist in other counties; it just will not be offered at your address next year. You will get a notice, usually in early October. Your current plan keeps working through December 31, and you do not lose Medicare. Because plans are sold county by county, other Medicare Advantage and Part D plans are almost always still available where you live, just a different menu than the plan you had.
Is a plan leaving my area the same as the plan being discontinued?
Not quite. A service-area reduction means the insurer is dropping your county but may still offer the plan elsewhere, so a similar plan could be available in a neighboring county. A non-renewal or termination means the plan is ending for everyone in every county, so there is no version of it to move to. Either way you get a special window to choose new coverage, but if the plan is only leaving your area, the useful question is what is still offered where you live.
Why would an insurer stop offering a plan in my county?
It is a business decision about that local market, not a judgment about you or your health. Common reasons include the insurer not being able to keep an adequate network of local doctors and hospitals, the plan not being financially sustainable or having low enrollment in that county, or the insurer refocusing on other regions. Medicare Advantage and Part D contracts are filed county by county, so an insurer can add or drop individual counties each year.
How do I find out which Medicare plans are still available in my county?
Use the official Medicare Plan Finder at Medicare.gov and enter your ZIP code. It lists every Medicare Advantage and Part D plan available in your county, with premiums, drug coverage, and star ratings. Check that a plan covers your doctors (its network) and your medications (its formulary) at your address, since both are set locally and change each year. You can also call 1-800-MEDICARE or your State Health Insurance Assistance Program (SHIP) for free help, or have CareRoute Decision Support research your county menu for you.
What happens if I do nothing?
If your Medicare Advantage plan leaves your area and you take no action, you generally return to Original Medicare (Part A and Part B), and you are not automatically enrolled in a plan available in your county. The catch is drug coverage: you will not have a Part D drug plan unless you enroll in one. Going 63 days or more without creditable drug coverage can trigger a permanent Part D late enrollment penalty. Letting the plan lapse without picking a replacement in your area is rarely the best choice.
When can I enroll in a new plan, and what is the deadline?
When a plan reduces its service area or is non-renewed or terminated, you get a Special Enrollment Period that generally runs from December 8 to the end of February to enroll in a plan still offered in your county. 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. Which Medigap policies are sold, and at what price, is set at the state level, so check what is available where you live. 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.
