Can You Switch from Medicare Advantage to Medigap?
Yes — but the timing and order of steps matter enormously. Get it right and the move is smooth. Get it wrong and you can face medical underwriting, coverage gaps, or a lifetime drug penalty. Here's the full playbook for Florida seniors.

We'll check your trial rights, windows & carrier options.
First: Do You Have a 12-Month Trial Right?
Federal law gives two groups a guaranteed path back to Medigap — no health questions, no denials, standard rates. Check these before anything else.
You Joined Medicare Advantage at 65
If you enrolled in a Medicare Advantage plan when you first became eligible for Medicare at 65, and you're still within your first 12 months on that plan, you can drop it, return to Original Medicare, and buy any Medigap plan sold in your area — guaranteed acceptance, no health questions.
Example: You turned 65 in March, joined an Advantage plan, and by November realize you want more doctor flexibility. You're inside the window — every Medigap plan is open to you.
You Left Medigap to Try Medicare Advantage
If you dropped a Medigap policy to join a Medicare Advantage plan for the first time, you have 12 months to change your mind. You can return to Original Medicare and get your same Medigap policy back from the same insurer — or if it's no longer sold, buy certain other plans guaranteed-issue.
Example: You had Plan G for years, tried an Advantage plan in January, and miss your old coverage by summer. Your old Plan G must be offered back to you.
Outside both trial rights?
You can still switch — but in Florida you'll almost always go through medical underwriting. Insurers can ask health questions, charge more, or decline. Many conditions are still insurable, and carriers differ widely in what they accept. This is exactly where an independent agent earns their keep: we know which Florida carriers are lenient on which conditions, before you apply.
When You Can Leave a Medicare Advantage Plan
Annual Enrollment Period
October 15 – December 7
Drop your Advantage plan and return to Original Medicare effective January 1. The most common switching window — and the busiest, so start early.
MA Open Enrollment
January 1 – March 31
Already on an Advantage plan January 1? You get one switch — including back to Original Medicare with a Part D plan — effective the first of the next month.
Special Enrollment Periods
Event-based, year-round
Moving out of your plan's service area, your plan leaving Medicare, qualifying for Extra Help, and other events open personal switching windows.
Remember: these windows control when you can leave Medicare Advantage. Getting into a Medigap plan is a separate approval unless a guaranteed-issue right applies.
The 5-Step Switch, Done in the Right Order
The order of operations is what protects you. Here's the sequence we run for every client making this move.
Confirm your enrollment window
AEP (Oct 15 – Dec 7) or MA Open Enrollment (Jan 1 – Mar 31) are the main exits from a Medicare Advantage plan. Special Enrollment Periods apply if you move, lose coverage, or qualify for other exceptions.
Check for guaranteed-issue rights
Within your first 12 months on Medicare Advantage? A trial right may let you buy Medigap with zero health questions. This is the single most valuable — and most missed — protection in the whole process.
Get approved for Medigap BEFORE you disenroll
If underwriting applies, apply and get approved for your Medigap policy first. Never drop your Advantage plan until the Supplement approval is in hand — otherwise you risk being stuck on Original Medicare with no gap coverage.
Add a standalone Part D drug plan
Medigap doesn't cover prescriptions. Enroll in a Part D plan effective the same day you return to Original Medicare to avoid gaps and lifetime late-enrollment penalties.
Time all effective dates to the same day
Advantage plan ends, Original Medicare resumes, Medigap starts, Part D starts — all on day one. We coordinate the paperwork so nothing slips through the cracks.
Switching Questions, Answered
What Florida seniors ask us most about moving from Medicare Advantage to a Supplement plan.
You can leave a Medicare Advantage plan only during specific windows — mainly the Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31). Buying the Medigap policy is the second, separate step: unless you have a guaranteed-issue right (like a trial right), Florida insurers can ask health questions and may decline you or charge more.
There are two trial rights. First: if you joined a Medicare Advantage plan when you first became eligible for Medicare at 65 and you're within your first 12 months, you can drop it, return to Original Medicare, and buy any Medigap plan with no health questions. Second: if you dropped a Medigap policy to try Medicare Advantage for the first time, you have 12 months to switch back and reclaim your old policy from the same insurer (or, if unavailable, buy certain other plans guaranteed-issue).
Usually yes, if you're outside your 6-month Medigap Open Enrollment Period and don't have a guaranteed-issue right. Florida has no 'birthday rule' — so most people switching from Medicare Advantage go through medical underwriting. Many health conditions are still insurable; an experienced agent knows which carriers are most flexible for which conditions.
If you disenroll from Medicare Advantage during the Annual Enrollment Period (October 15 – December 7), you return to Original Medicare on January 1. Your Medigap policy and standalone Part D drug plan should both be lined up to start that same day so you're never left with a coverage gap.
Yes. Medicare Advantage plans usually bundle drug coverage, but Medigap plans never include it. When you switch, you'll enroll in a standalone Part D prescription drug plan alongside your Medigap policy. Skipping this step can trigger the Part D late enrollment penalty — a lifetime surcharge.
The most common reasons we see: wanting to keep specific doctors without network restrictions, tiring of prior authorizations and referrals, spending part of the year in another state, or facing rising out-of-pocket costs with a serious diagnosis. Medigap offers any-Medicare-doctor access and highly predictable costs, in exchange for a monthly premium.
Yes — you can join a Medicare Advantage plan during any Annual Enrollment Period. Going from Medigap to Advantage has no health questions. It's the reverse direction (back into Medigap) that involves underwriting, which is why we recommend making the Medigap decision carefully the first time.
