Your Medicare Advantage Plan Isn’t Renewing? Here’s What You Need to Know About Guaranteed Issue Rights and Medicare Supplement Opportunities
If you’ve received notice that your Medicare Advantage plan isn’t renewing for the upcoming year, you’re not alone. Every year, insurance companies make changes to their Medicare Advantage offerings—sometimes reducing coverage areas, modifying benefits, or deciding not to renew plans altogether.
While that news can feel unsettling, there’s an important silver lining:
You may qualify for a special Guaranteed Issue Right to enroll in a Medicare Supplement (Medigap) plan—but that opportunity is often time-sensitive and might be your only chance to get a supplement without medical underwriting.
Let’s break down what that means, why it matters, and what steps you should take right now.
---
What Happens When a Medicare Advantage Plan Ends?
When a Medicare Advantage (Part C) plan is discontinued or not renewed by the insurance company:
Your plan ends on December 31st of the current year.
Medicare automatically returns you to Original Medicare (Part A and Part B) starting January 1st of the new year.
You then have the option to either choose another Medicare Advantage plan or enroll in a Medicare Supplement plan to go with your Original Medicare.
The key is understanding your rights and timing—because once your Advantage plan ends, the clock starts ticking on your special enrollment period.

What Are Guaranteed Issue Rights?
Normally, if you want to enroll in a Medicare Supplement (Medigap) plan, insurance companies can:
Require medical underwriting,
Deny you coverage based on pre-existing conditions, or
Charge you higher premiums due to your health.
However, when certain events happen—like your Medicare Advantage plan ending through no fault of your own—you gain what’s called a Guaranteed Issue Right (also known as a “Medigap protection”).
This right means that, for a limited time, insurance companies must: ✅ Accept your Medigap application
✅ Offer you coverage at the same price as a healthy applicant
✅ Not delay or deny coverage for pre-existing conditions
---
When Do Guaranteed Issue Rights Apply?
There are several situations where Guaranteed Issue Rights apply, but in this case, it’s triggered when:
Your Medicare Advantage plan is leaving Medicare, or
Your plan stops servicing your area, or
Your insurer decides not to renew your plan for the next year
This is a Special Enrollment Period created to protect beneficiaries from losing coverage through no fault of their own.

Your Guaranteed Issue Time Window
If your Medicare Advantage plan isn’t renewing, your Guaranteed Issue window typically begins 60 days before your coverage ends and continues for 63 days after it ends.
That means you usually have from November through early March (depending on your plan’s termination date) to take advantage of this right.
⚠️ Important: Once that window closes, insurance companies can once again use medical underwriting to decide whether to accept you into a Medicare Supplement plan. Missing the window could mean losing your one-time opportunity to enroll without health questions.

Which Medicare Supplement Plans Are Available Under Guaranteed Issue?
Depending on your state and situation, you’re typically entitled to enroll in one of the following Medigap plans:
Plan A
Plan B
Plan C (if eligible before 2020)
Plan D
Plan F (if eligible before 2020)
Plan G (for newer enrollees)
Plan K or Plan L in some cases
Each plan provides different levels of coverage to fill the “gaps” left by Original Medicare—such as deductibles, coinsurance, and copayments.

Why This May Be Your Only Chance
If you currently have health conditions—such as heart disease, diabetes, COPD, or a history of cancer—this Guaranteed Issue Right is extremely valuable.
Outside of your initial Medicare enrollment period (when you first turn 65 or enroll in Part B), most people can only get a Medigap plan through medical underwriting. That means insurance companies can:
Ask health questions,
Review your medical records, and
Potentially deny your application.
Once your Guaranteed Issue window expires, you may never again have the same freedom to enroll in a supplement without your health being a factor.
That’s why it’s critical to review your options as soon as possible—while the Guaranteed Issue protections are still in effect.

Why Choose a Medicare Supplement Plan
Medicare Supplement (Medigap) plans are popular among those who want predictable costs and stable coverage year after year.
Here are a few reasons why many people switch when their Advantage plan ends:
Freedom to choose doctors – You can see any provider nationwide who accepts Medicare.
No referral requirements – You don’t need permission to see a specialist.
Lower out-of-pocket costs – Many plans cover all or most of your medical expenses after Medicare pays its share.
No network restrictions – Perfect for people who travel or live in multiple states.
Guaranteed renewable for life – As long as you pay your premium, the insurance company can’t drop your coverage.
For many retirees, Medigap plans provide peace of mind—especially when faced with the uncertainty of a Medicare Advantage plan ending.

What About Prescription Drug Coverage?
Medicare Supplement plans do not include prescription drug coverage.
If you switch from Medicare Advantage back to Original Medicare and choose a Medigap plan, you’ll also need to enroll in a standalone Part D (prescription drug) plan to avoid potential late-enrollment penalties and maintain drug coverage.
Your Guaranteed Issue Right for Medigap doesn’t extend to Part D, but you do have a separate Special Enrollment Period to pick a drug plan when your Advantage plan ends.

Steps to Take Right Now
1. Review Your Termination Notice
Carefully read the letter from your current Medicare Advantage plan. It will confirm the end date and outline your options.
2. Mark Your Calendar
Remember—you have 63 days after your plan ends to use your Guaranteed Issue Right.
3. Compare Medicare Supplement Plans
Look at Medigap Plan G, Plan N, and others available in your state. Each offers different levels of protection and monthly premiums.
4. Apply During the Guaranteed Issue Window
Don’t wait until the deadline. Processing times can vary, and you want your new coverage to start without any gap.
5. Add a Part D Plan
Choose a prescription drug plan to accompany your Medigap coverage.
6. Work With a Licensed Broker
Independent brokers—like The Medicare Dude—can compare plans from multiple companies, explain your rights, and help ensure you don’t miss your window.

Final Thoughts
If your Medicare Advantage plan isn’t renewing this year, don’t panic—but don’t delay, either.
You have valuable Guaranteed Issue Rights that may allow you to enroll in a Medicare Supplement plan without health questions or denial—but the opportunity only lasts a short time.
For many people, this is a once-in-a-lifetime chance to lock in stable, long-term coverage that travels with you and doesn’t change from year to year.
