How a carrier non-renewal notice creates a rare federal Guaranteed Issue window to return to Original Medicare and enroll in Medicare Supplement Plan G without answering medical questions.
Direct answer: When a Medicare Advantage carrier discontinues or non-renews your plan in Polk County for 2027, federal law (42 U.S.C. § 1395ss) grants you a Guaranteed Issue (GI) right to buy a Medicare Supplement policy—including Plan G with participating carriers in Florida—without answering health questions or undergoing medical underwriting. If you previously wanted Plan G but were locked out due to pre-existing conditions, your carrier's non-renewal notice is the document that unlocks this window.
Every year during Annual Enrollment (October 15–December 7), thousands of Florida seniors ask the same question: "Can I switch from my Medicare Advantage plan to a Medicare Supplement (Medigap) Plan G?"
In most normal years, the answer is tough: unless you are in your initial 6-month Medigap Open Enrollment period when you first turned 65, switching from an Advantage plan to Plan G requires passing medical underwriting. If you have been treated for heart conditions, diabetes with insulin, cancer, rheumatoid arthritis, or scheduled joint replacements, insurance companies can legally deny your application or charge higher rates.
However, for 2027, hundreds of beneficiaries across Lakeland, Winter Haven, and Central Florida received an official letter stating that their Medicare Advantage plan contract is ending on December 31. If you hold that letter, the rules change completely.
The Non-Renewal "Golden Ticket": Federal Guaranteed Issue Rights
Under federal Medicare law and Florida insurance guidelines, if your Medicare Advantage plan stops offering coverage in your county or service area, you have what Medicare calls Guaranteed Issue Right #1.
Under this federal protection, insurance companies selling Medigap policies:
- Must sell you a Medigap policy (including Plan G for individuals eligible for Medicare on or after January 1, 2020).
- Cannot deny your application based on your health history or medical conditions.
- Cannot place waiting periods on pre-existing health conditions.
- Cannot charge you more because of past or present health problems.
This means a plan termination is not a disaster—for many seniors, it is the exact opportunity they have been waiting years for to get comprehensive coverage without network restrictions under Medicare Supplement Plan G.
Why Beneficiaries Choose Plan G Over Another Advantage Plan
When an Advantage plan non-renews, the carrier often tries to steer you into another one of their HMO or PPO plans. But you are under no obligation to stay with that carrier. Comparing Plan G gives you:
- Zero Network Restrictions: See any doctor, specialist, or hospital anywhere in the United States that accepts Original Medicare (including Lakeland Regional Health, Watson Clinic, Orlando Health, Moffitt Cancer Center, and Mayo Clinic in Jacksonville) without referrals.
- Predictable Out-of-Pocket Costs: After paying the standard Part B annual deductible, Plan G pays 100% of all Medicare-covered hospital, physician, and outpatient coinsurance.
- No Prior Authorization Delays: Medicare makes the coverage decision, not an insurance company claims adjuster.
The 63-Day Window: Critical Deadlines You Must Meet
60 Days Before to 63 Days After Coverage Ends
Under federal rules, you can apply for your Guaranteed Issue Medigap policy as early as 60 calendar days before your plan ends (around November 2) and up to 63 calendar days after December 31. However, to guarantee your new Plan G coverage is active on January 1, 2027 without a single day of uncovered gap, your application should be submitted before the December 7 AEP deadline.
The Critical Catch: You Must Enroll in a Standalone Part D Plan
There is one vital requirement that beneficiaries frequently overlook when moving from Medicare Advantage to Medicare Supplement insurance:
Plan G does not cover prescription drugs.
Because Medicare Advantage plans bundle medical and Part D drug coverage into one card, leaving that plan means you must enroll in a standalone Medicare Part D Prescription Drug Plan (PDP). Under the standard rules, you must select and enroll in your standalone Part D plan between October 15 and December 7. If you go more than 63 days without creditable drug coverage, you can incur a lifetime Part D late-enrollment penalty.
CMS has confirmed that the standard Part D out-of-pocket prescription cap is established for 2027. We verify every single one of your current medications and dosages against the 2027 Florida formularies to pair your Plan G with the lowest-cost Part D plan available.
4 Steps to Claim Your Plan G Guaranteed Issue Right
- Do NOT throw away your non-renewal letter: The Medigap insurance company will require a physical or scanned copy of the official termination notice as legal proof of your Guaranteed Issue right.
- Compare Polk County Plan G rates: Medigap benefits are standardized by the federal government—a Plan G with one carrier has the exact same medical benefits as Plan G with another. The only difference is the monthly premium and the carrier's financial stability.
- Select your standalone Part D plan before December 7: Align your prescription medications with the best pharmacy network in Lakeland.
- Submit your application with proof of non-renewal: Ensure your effective date is set for January 1, 2027 so you experience zero gap in coverage.

Common questions
Can I switch from Medicare Advantage to Plan G without answering health questions?
Yes, but only if you have a qualifying federal Guaranteed Issue right. An involuntary non-renewal or termination letter from your Medicare Advantage plan proves that your plan is ending on December 31, granting you a 63-day window to purchase Medigap Plan G without medical underwriting.
What proof do I need to get Guaranteed Issue for Medigap Plan G?
You must provide a copy of your official carrier non-renewal or plan termination notice (often dated in late September or October) showing that your specific plan contract will not be offered in your service area next year.
Does Plan G include prescription drug coverage?
No. Medicare Supplement insurance (Medigap) works alongside Original Medicare (Parts A and B) to cover deductibles and coinsurance, but it does not cover retail prescription drugs. You must enroll in a standalone Medicare Part D plan between October 15 and December 7 to avoid drug coverage gaps and penalties.
When does the Guaranteed Issue window open and close?
Federal rules permit you to apply as early as 60 calendar days before your Medicare Advantage plan ends (around November 2) and up to 63 calendar days after it ends. To ensure your coverage starts January 1 with no coverage gap, applications should be submitted during Annual Enrollment before December 7.
