If your Medicare Advantage plan is ending or will no longer serve your South Florida address in 2027, you may have a federal guaranteed-issue right to buy certain Medicare Supplement policies without medical underwriting. That can be an important option for people who would otherwise need to answer health questions in Florida.
The right is not automatic in every situation, and it does not mean every Medigap plan is available without underwriting. The reason your coverage is ending, the notice you received, the coverage you choose next and the date you apply all matter.
The short answer: you may qualify for Medigap without underwriting
Medicare calls these protections guaranteed-issue rights. When a right applies, an insurance company must sell you a qualifying Medigap policy that it offers, must cover your pre-existing health conditions and cannot charge you more because of your health status.
One qualifying situation can occur when your Medicare Advantage plan leaves Medicare, stops providing care in your area or otherwise ends coverage through no fault of your own. A county-level service-area reduction may qualify when your plan will no longer be available at your permanent address.
A plan ending is different from a plan changing
An Annual Notice of Change can show higher copays, a different drug formulary, benefit reductions or network changes while the plan itself continues. Those changes alone do not necessarily create a federal right to buy Medigap without underwriting.
A non-renewal, termination or service-area reduction notice says that the plan will not be available to you for the next year. That is the document that may establish a guaranteed-issue right. Read the entire notice and save every page.
- Plan continues with different benefits: usually an ANOC issue, not an automatic Medigap right.
- Plan contract ends: may create guaranteed-issue and Special Enrollment Period rights.
- Plan removes your county or address from its service area: may create similar protections.
- Your doctor leaves the network but the plan continues: does not by itself generally create a federal Medigap guaranteed-issue right.
You must choose Original Medicare to use the Medigap right
Medigap works only with Original Medicare Part A and Part B. It cannot supplement a Medicare Advantage plan or pay that plan's copays, deductibles or premiums.
If your terminating Medicare Advantage plan includes prescription coverage and you return to Original Medicare, you should also review a standalone Part D plan. Medigap policies sold today do not include outpatient prescription drug coverage.
The 60-day-before and 63-day-after Medigap window
Medicare says you can generally apply for a qualifying Medigap policy beginning 60 days before your Medicare Advantage coverage ends and no later than 63 days after it ends. If coverage ends December 31, the protected application window may begin in early November and extend into early March.
Do not treat the final day as a target. Applying early gives the insurer time to review your termination notice, confirm your guaranteed-issue status and coordinate a January 1 effective date. Medigap coverage cannot begin while you are still enrolled in Medicare Advantage.
Which Medigap plans can you buy under federal guaranteed issue?
Medicare's federal guidance generally lists Medigap Plans A, B, C, D, F, G, K and L when this guaranteed-issue situation applies and the policy is sold by an insurer in your state. Plans C and F are generally unavailable to people who first became eligible for Medicare on or after January 1, 2020.
This distinction matters because a federal guaranteed-issue right does not necessarily give you access to every standardized plan. Plan N, for example, is not included in Medicare's general federal list for this situation. A carrier may consider another application under its own rules, but medical underwriting may apply unless a different protection is available.
- Plan G is generally included for people eligible to purchase it when offered by the carrier.
- Plan N is not automatically included under this specific federal guaranteed-issue right.
- Plan availability, premiums and carrier participation still vary by Florida ZIP code.
- Confirm whether a high-deductible version is available rather than assuming the guaranteed-issue right extends to it.
What happens if you enroll in another Medicare Advantage plan?
You can compare another Medicare Advantage plan instead of returning to Original Medicare. However, Medigap cannot be paired with that replacement Medicare Advantage plan, and the guaranteed-issue right described here generally depends on switching to Original Medicare.
Compare both paths before enrolling. Once you choose another Medicare Advantage plan, you should not assume you can later change your mind and obtain Medigap without underwriting. A separate trial right or another protected situation would need to apply.
What happens if you do nothing?
When a Medicare Advantage contract is not renewed, Medicare says you will generally be enrolled in Original Medicare if you do not join another Medicare Advantage plan before the current plan ends. That does not automatically enroll you in a Medigap policy or guarantee that your existing prescription coverage continues.
Original Medicare has no annual out-of-pocket maximum for Part A and Part B services. You may also need a standalone Part D plan to avoid a drug-coverage gap and a possible late-enrollment penalty later. Doing nothing can therefore leave important pieces of coverage unresolved.
Your Medicare Special Enrollment Period is a separate protection
The opportunity to choose another Medicare Advantage or Part D plan and the right to purchase certain Medigap policies are related but separate. Each has its own rules and deadlines.
Medicare currently states that when a Medicare Advantage or drug plan contract is not renewed, the Special Enrollment Period to choose another Medicare plan runs from December 8 through the last day of February in the following year. Using Medicare Open Enrollment from October 15 through December 7 can make a January 1 transition easier, but review the dates stated in your official notice.
Why the decision is especially important in South Florida
Medicare Advantage availability and provider networks can differ across Broward, Miami-Dade and Palm Beach counties. A carrier may continue offering plans in Florida while discontinuing one contract or removing a particular county from a service area.
Original Medicare plus Medigap generally offers access to any provider nationwide that accepts Medicare, while a replacement Medicare Advantage plan may use a local HMO, HMO-POS or PPO network. South Florida residents who use doctors or hospitals across county lines should compare those access rules carefully.
- Confirm your permanent residential address and county.
- List every doctor, specialist, hospital and outpatient facility you want to keep.
- Consider travel, seasonal residence and out-of-state care needs.
- Compare the Medigap premium with Medicare Advantage copays and maximum out-of-pocket exposure.
- Review separate Part D coverage using your exact prescriptions and pharmacies.
Documents to keep before applying
A Medigap insurer may ask for proof that your Medicare Advantage coverage is ending. Keep the original documents and submit copies when requested.
- Plan non-renewal, termination or service-area reduction notice
- Annual Notice of Change
- Medicare card and current plan card
- Any letter showing the final date of coverage
- Enrollment confirmations for Original Medicare and Part D
- Medigap application and approval confirmation
Do not cancel coverage before everything is confirmed
Coordinate the Medicare Advantage end date, Original Medicare, Part D and Medigap so the new coverage begins without a gap. Do not cancel current coverage independently unless the plan, Medicare or your advisor confirms that it is necessary.
Before relying on the new arrangement, obtain written confirmation that the Medigap policy is approved and verify its effective date. Keep copies of every application and confirmation.

Frequently asked questions
Can I get Medigap without underwriting if my Medicare Advantage plan ends?
You may have a federal guaranteed-issue right if your Medicare Advantage plan terminates, leaves Medicare or stops serving your residential area and you return to Original Medicare. The reason coverage ends and your application timing determine whether the protection applies.
Can I buy Medigap Plan G if my Medicare Advantage plan leaves Florida?
Plan G is generally included among the standardized policies available under this federal guaranteed-issue situation when it is sold by the carrier in your area and you are otherwise eligible. Carrier availability and premiums still vary.
Can I buy Plan N without underwriting when my Medicare Advantage plan ends?
Not automatically under this specific federal guaranteed-issue right. Medicare's general list includes Plans A, B, C, D, F, G, K and L, subject to eligibility and availability, but not Plan N. Another protection or the carrier's underwriting rules may apply.
Does receiving an ANOC give me a Medigap guaranteed-issue right?
Not by itself. An ANOC usually explains changes to a plan that will continue. A termination, non-renewal or service-area reduction that ends your coverage may create the guaranteed-issue right.
How long do I have to apply for Medigap after my Advantage plan ends?
Medicare says the federal application window can begin 60 days before the Medicare Advantage coverage ends and generally closes 63 days after it ends. Applying early is safer and helps coordinate the effective date.
Do I need a Part D plan if I switch to Original Medicare and Medigap?
Usually yes if you want outpatient prescription coverage. Modern Medigap policies do not include Part D, so you generally need to enroll in a separate Medicare drug plan.
