Each fall, some Medicare Advantage plans shrink their service areas or close entirely, and 2027 is a bigger year for this than most. National analysis of CMS data shows several of the largest insurers are leaving hundreds of counties. That does not mean your Kentucky plan is ending. It does mean this is a year to read your mail carefully and confirm, county by county, what your plan is doing.
This guide explains what the national numbers show, what they do not show, and exactly how to check whether your own coverage is changing.
What the National Data Shows for 2027
On October 9, 2026, KFF published an analysis of the official CMS plan landscape files comparing where Medicare Advantage prescription drug plans (MA-PDs) are offered in 2026 versus 2027. Among the findings:
- UnitedHealth Group is exiting 228 counties and entering 9 new ones.
- Humana is exiting 62 counties and entering 4 new ones.
- Ten insurers made footprint changes affecting at least 50 counties each, with some regional carriers reducing even more.
- Nationally, 193 counties will have no general-enrollment MA-PD at all in 2027, up from 123 in 2026.
Number of U.S. counties where each insurer will no longer offer any general-enrollment MA-PD plan
| Item | Counties exited |
|---|---|
| UnitedHealth Group | 228 |
| Humana | 62 |
These are nationwide, insurer-level figures. They do not show which counties are affected and do not establish that either insurer is leaving any Kentucky county.

Two points matter for Kentucky readers. First, the 16 states that will have counties with no MA-PD option in 2027 do not include Kentucky. Second, CMS's own 2027 Kentucky fact sheet reports that 100% of people with Medicare in Kentucky have access to at least one Medicare Advantage plan. Availability of a plan, though, is not the same as availability of your plan.
What Is a Medicare Advantage Service Area?
A service area is the list of counties where a Medicare Advantage plan is approved to enroll members. Plans are offered county by county, which is why a neighbor one county over in Pulaski or Whitley County may see a different set of choices than someone in Laurel County.
An insurer also typically offers several plans, and each plan can have its own service area, provider network, and benefits. One plan from a company may leave a county while another plan from the same company stays.
Why Insurers Discontinue Plans or Exit Counties
Insurers decide each year where to offer plans. Reasons cited in industry reporting for 2027 include rising medical costs, higher use of services, and changes in Medicare payment. A plan may also be ended because too few people enrolled, because the provider network could not be maintained, or because the company is consolidating several plans into one.
None of these reasons tell you anything about the quality of care you received. They are business decisions, which is why the practical question is simply: what happens to my coverage on January 1?
Plan Termination, Service-Area Exit, or Routine Change?
These terms sound similar but lead to very different situations.
| Situation | What it means | Do you need to act? |
|---|---|---|
| Routine annual change | Your plan continues, but premiums, copays, drug coverage, or networks change for 2027. | Not required, but review the changes before December 7. |
| Service-area reduction | Your plan continues elsewhere but will no longer be offered in your county. | Yes. You will need new coverage for 2027. |
| Plan termination (non-renewal) | The plan will not be offered anywhere in 2027. | Yes. You will need new coverage for 2027. |
| Plan consolidation | Your plan is merged into another plan from the same company. | Review carefully. Benefits and networks may differ. |

How to Recognize a Termination or Non-Renewal Notice
If your plan is leaving your county or ending, the plan is required to send you a written non-renewal notice, generally by early October. It will usually say that your plan will not be offered in your area next year, give the date coverage ends, and explain your options.
This letter is different from the Annual Notice of Change (ANOC), which every member receives each fall and describes changes to a plan that is continuing. If you are unsure which letter you received, call the member services number on your plan ID card or contact us and we can read it with you.
How to Check Whether Your Medicare Plan Is Changing in Kentucky
- Step 1: Find your plan's exact name and ID. Your member ID card lists the plan name and a plan number (it often begins with H or R). Insurers sell many plans with similar names, so the ID matters.
- Step 2: Read your Annual Notice of Change. Look at the first page for any statement that the plan is ending or leaving your area, then compare premiums, copays, the maximum out-of-pocket limit, and drug coverage.
- Step 3: Look for a separate non-renewal letter. Check mail from both your plan and Medicare since late September.
- Step 4: Search the Medicare Plan Finder. At Medicare.gov Plan Finder, enter your ZIP code and county. If your current plan does not appear for 2027 in your county, that is a strong signal it is not available there.
- Step 5: Confirm with the plan. Call member services and ask directly: "Is my plan, with this plan ID, offered in my county for 2027?"
- Step 6: Re-check your doctors and drugs for any plan you are considering, even if it comes from the same insurer.
What Options Exist If Your Plan Is Discontinued?
If your plan is ending in your area, you generally can:
- Choose a different Medicare Advantage plan offered in your county.
- Return to Original Medicare and add a stand-alone Part D drug plan.
- Combine Original Medicare with a Medicare Supplement (Medigap) policy, which helps pay costs Original Medicare does not.

Enrollment Rights and Medigap Protections
You can make any change during Medicare Open Enrollment, October 15 through December 7, 2026, for coverage that starts January 1, 2027.
When a plan leaves your area or stops operating, Medicare also provides a Special Enrollment Period (SEP), which gives you extra time to choose new coverage. Per Medicare.gov's Special Enrollment Period rules, the timing depends on your situation, so confirm your specific dates.
In many cases you may also have a Medigap guaranteed-issue right. That means insurance companies must sell you certain Medigap policies without charging more for health conditions, within a limited window around the date your plan coverage ends. Which policies qualify and the exact timing depend on your circumstances, so do not assume the window stays open indefinitely.
What Happens If You Take No Action?
If your Medicare Advantage plan ends and you do not choose new coverage, you generally return to Original Medicare. That keeps your hospital and medical coverage, but it may leave you without prescription drug coverage. Going without creditable drug coverage can lead to a gap at the pharmacy and, in some cases, a permanent Part D late enrollment penalty. Waiting is rarely the best choice.
Why a County-Level Review Matters
National headlines describe insurer totals. Your situation depends on your county, your plan ID, your doctors, and your prescriptions. A careful review for a London or Laurel County resident starts with the plans actually filed for that county and then checks each one against your providers and medications. For broader timing questions, our Kentucky AEP guide walks through the season step by step.
Key Takeaways
- National county exits by UnitedHealth Group (228) and Humana (62) are real, but they are not proof that any Kentucky plan is ending.
- Your plan must notify you in writing if it is leaving your area.
- Check your plan ID in the Medicare Plan Finder for your county.
- If your plan ends, you may have a Special Enrollment Period and Medigap guaranteed-issue rights.
- Doing nothing can leave you without drug coverage.
Frequently Asked Questions
Is my Medicare Advantage plan leaving Laurel County in 2027?
We cannot answer that from national data. Check your ANOC, any non-renewal letter, and the Plan Finder for your county, or ask us to review it with you.
If my insurer is leaving some counties, is my plan affected?
Not necessarily. Insurers exit some counties and stay in others, and each plan has its own service area.
Do I have to re-enroll if my plan is continuing?
No. If your plan continues in your county, you stay enrolled automatically unless you choose a change.
How long do I have to pick a new plan if mine is ending?
You can use Open Enrollment through December 7, and a Special Enrollment Period may give you additional time. Confirm your exact dates with Medicare or your plan.
Can I switch to a Medigap policy without health questions?
Possibly. When a Medicare Advantage plan leaves your area, you may have guaranteed-issue rights for certain Medigap policies for a limited time.
