Someone called last month from Savannah: "I'm leaving my Advantage plan in December, the agent said I can get any Medigap I want." Run Plan Finder and read underwriting rules before you cancel anything.
That agent skipped the underwriting conversation. Leaving Medicare Advantage during Annual Enrollment lets you return to Original Medicare. It does not automatically force a Medigap carrier in Georgia to sell you Plan G without health questions. Guaranteed issue is a legal term with deadlines and qualifying circumstances. Frustration with referrals does not create a guaranteed-issue window on its own.
Leaving Medicare Advantage does not automatically give you a new Medigap Open Enrollment Period or guaranteed-issue right. Whether you can buy Medigap without medical underwriting depends on the specific circumstances, timing, and any applicable federal or state protections.
This post replays the guaranteed-issue situations that actually exist in Florida, Alabama, Georgia, and North Carolina. I see this confusion every December when Advantage frustration peaks but underwriting rules stay unchanged. Our Advantage vs. Medigap Florida post explains path trade-offs. Our trial period guide goes deeper on the 12-month window.
What is Medigap guaranteed issue?
Medigap guaranteed issue is a legal right to buy certain standardized supplement policies without health questions during protected periods, most commonly your 6-month Medigap Open Enrollment Period at Part B.
Medigap policies pay after Original Medicare on covered services. They follow Medicare providers, not a carrier network directory. Medigap Open Enrollment Period and guaranteed issue right are not interchangeable. Open enrollment is the federally protected six-month window at Part B. Guaranteed issue is a separate federal or state protection that arises from qualifying circumstances, such as losing certain coverage or using an applicable Medicare Advantage trial right.
Outside protected periods, carriers in the Southeast may underwrite: health questionnaires, prescription cross-checks, and declinations based on their current guidelines. Florida, Alabama, Georgia, and North Carolina do not offer a verified annual Medigap birthday switching rule comparable to states like California or Oregon. Contact your state insurance department if you need to confirm current state-specific rights.
When can I buy Medigap without medical underwriting in the Southeast?
The widest window is your 6-month Medigap Open Enrollment Period at Part B; federal triggers cover retiree coverage loss and qualifying Advantage trial exits.
Your 6-month Medigap Open Enrollment Period starts the first month you're 65 or older and enrolled in Medicare Part B. During this window, carriers generally must sell you any Medigap plan they offer in your state without medical underwriting (Medicare.gov).
Federal guaranteed-issue rights also apply in specific situations documented in CMS guidance (Medicare.gov). Examples include losing employer retiree supplement coverage and certain Medicare Advantage or Medicare SELECT exits within required timelines.
Moving to another state does not automatically create a new Medigap Open Enrollment Period. However, moving can create specific Medigap rights in certain circumstances, so check the rules that apply to your existing policy and new state before dropping coverage (Medicare.gov).
Federal vs. state Medigap protections
| Situation | Federal Medigap protection? | Key point |
|---|---|---|
| 6-month Medigap Open Enrollment Period | Yes | Important federal protections generally apply during this period |
| Applicable Medicare Advantage trial right | Yes | Special federal Medigap rights can apply when the trial-right requirements are met |
| Certain loss-of-coverage situations | Yes, when applicable | Specific federal guaranteed-issue rights and deadlines may apply |
| Medicare Advantage plan leaves Medicare/service area | May apply | Exact rights depend on the circumstances |
| Annual Enrollment Period | No automatic Medigap guaranteed-issue right | AEP is primarily for Medicare Advantage and Part D changes |
| Ordinary Medigap policy switch outside a protected period | Generally no federal guaranteed-issue right | Medical underwriting may apply |
| Additional state protections | Depends on state | State law may provide rights beyond federal guaranteed issue |
Annual Enrollment Period vs. Medigap rights
Annual Enrollment Period (October 15 through December 7) primarily allows changes involving Medicare Advantage and Part D. It does not automatically create a federal Medigap guaranteed-issue right.
You can generally leave Medicare Advantage during AEP and return to Original Medicare effective January 1. That does not mean a Medigap carrier must ignore your health history. Unless an applicable federal or state guaranteed-issue right applies, expect underwriting when you apply for a new supplement after AEP.
Does leaving Medicare Advantage create a guaranteed issue window?
First-time Advantage enrollees may have a 12-month trial right to return to Original Medicare with special Medigap purchase rights; everyone else usually faces health questions unless another trigger applies.
Federal trial rights apply when you enroll in Medicare Advantage for the first time after age 65 and try it within your first year. If you joined a Medicare Advantage plan when you were first eligible for Medicare at 65 and decide within the applicable trial period that you want to return to Original Medicare, you generally have a federal right to buy any Medigap policy sold by an insurance company in your state, subject to the applicable timing rules (Medicare.gov).
After the trial window closes, leaving Advantage during AEP or with an SEP generally requires underwriting in FL, AL, GA, and NC unless another guaranteed-issue trigger applies. Outside guaranteed-issue protections, Medigap insurers may ask health questions and may accept, rate, or decline an application based on their current underwriting guidelines.
Annual Enrollment Period lets you disenroll from Advantage effective January 1. It does not force Medigap carriers to ignore your chart. Before dropping your current coverage, confirm what Medigap rights apply to your situation and whether the replacement coverage has been accepted and is effective.
Should I verify my doctors accept Original Medicare before buying Medigap?
Yes, Medigap pays after Original Medicare only; confirm Medicare assignment with each must-keep provider before you leave Advantage.
Search provider directories on Medicare.gov or call billing offices directly. Ask whether the physician accepts Medicare assignment for the services you need. Before changing coverage, check each provider you consider essential and confirm that they accept Medicare and that the coverage you are considering works with your providers.
A clean Advantage directory screenshot does not prove Original Medicare acceptance. Billing offices know the difference. Get yes or no answers before you cancel Part C.
Hypothetical examples: three situations that go wrong
Hypothetical example — Pensacola: A Florida beneficiary enrolled in Medicare Advantage at 65 for dental extras and later wanted Medigap after the applicable trial period ended. Applying for Medigap could involve medical underwriting unless another guaranteed-issue right applies.
Hypothetical example — Augusta: A beneficiary received a Medicare Advantage plan non-renewal or service-area exit notice. Federal rules may provide a guaranteed-issue window with specific deadlines and plan-letter limits depending on the circumstances. Matching the application date to the notice deadline matters more than AEP convenience.
Hypothetical example — Raleigh: A beneficiary moved from Florida to North Carolina and assumed state switching rules were identical. State Medigap protections differ. North Carolina provides a one-time six-month open enrollment period at 65 and state-mandated under-65 access to Plans A, D, or G for eligible disability beneficiaries (NC DOI), but ordinary post-65 switches outside protected periods may still require underwriting.
I push back on any agent who promises "any Medigap anytime" when you are leaving Advantage mid-contract without naming the federal trigger that applies.
State-specific notes: FL, AL, GA, and NC
Florida: F.S. 627.6741 requires a six-month Medigap open-enrollment period beginning the first month a person is 65 or older and enrolled in Part B, with additional guaranteed-issue periods when group coverage ends (Florida CFO). Florida policies include a separate 30-day free-look period after delivery to return a policy for a refund. That is not an annual birthday switching rule.
Alabama: Alabama implements federal guaranteed-issue standards in Ala. Admin. Code r. 482-1-071-.12. No verified annual Medigap birthday rule applies.
Georgia: O.C.G.A. § 33-43-3 provides a six-month enrollment period tied to Part B enrollment at 65. Georgia has not adopted a verified annual Medigap birthday switching rule.
North Carolina: G.S. 58-54-45 guarantees under-65 Medicare disability beneficiaries access to Plans A, D, or G, with a new six-month open enrollment period when they turn 65 (NC DOI). North Carolina does not provide a verified general annual birthday rule for all Medigap policyholders.
Do not assume one state's Medigap rules travel when you move across the Southeast.
Underwriting after open enrollment, what carriers ask
Outside guaranteed issue, expect health questions on tobacco use, height and weight, recent hospitalizations, and prescription use. Prescription cross-checks against application answers are common. Rated policies charge surcharges above standard premium. Declinations happen.
If you're outside a guaranteed-issue period, compare available Medigap options and understand each carrier's current underwriting requirements before submitting an application.
Plan letter limits during guaranteed issue
Federal guaranteed-issue triggers specify which Medigap letters carriers must offer in each situation. The Medicare Advantage trial right for first-time enrollees at 65 generally allows purchase of any Medigap policy sold in your state, not a fixed short list of plan letters (Medicare.gov). Other federal triggers may limit available letters. You cannot demand Plan G under every guaranteed-issue situation. Match the federal rules to the trigger that applies before you cancel Advantage.
Charleston and Jacksonville snowbirds who enrolled in Advantage at 65 for Florida dental often discover at 68 that underwriting may apply when the trial window closed while they were traveling. Model the one-way door before you leave supplements.
North Carolina and Georgia do not grant extra guaranteed-issue rights beyond federal protections and the NC under-65 mandate when your Advantage plan non-renews. Federal non-renewal SEP rules may apply, but plan availability still follows CMS and state rules. Read the non-renewal notice deadline line before you assume AEP timing is flexible.

- Medigap guaranteed issue means a carrier must sell you certain standardized policies without health questions during a protected situation and deadline, not whenever you feel like switching.
- Your 6-month Medigap Open Enrollment Period starts the first month you are 65 or older and enrolled in Medicare Part B; it does not automatically restart later.
- Leaving Medicare Advantage does not automatically give you a new Medigap Open Enrollment Period or guaranteed-issue right; timing and qualifying federal or state protections matter.
- Florida, Alabama, and Georgia generally follow federal Medigap protections without a verified annual birthday switching rule; North Carolina adds under-65 guaranteed access to Plans A, D, or G for eligible disability beneficiaries.
