A question our office hears often, especially during the annual enrollment period, is whether you can leave a Medicare Advantage plan for a Medicare supplement. Yes, you can switch from Advantage to Medigap, but only during certain windows, and after your first 12 months, you will need to health qualify.
Timing also matters when you move from a Medicare supplement to a Medicare Advantage plan. Below, we cover the 12-month windows, enrollment dates, and health requirements for both switches.
Switching from a Medicare Supplement to Medicare Advantage
If you already have a Medicare supplement and want to try a Medicare Advantage plan, the process is fairly straightforward. You just need to know which window applies to you.
The 12-Month Window After Your First Supplement Enrollment
When you enroll in a Medicare supplement for the first time, you have a 12-month window to move to a Medicare Advantage plan. You can make this change at any point during those first 12 months.
Waiting for the Annual Enrollment Period
After the 12-month window ends, you can still move from a supplement to an Advantage plan. You will need to wait until the annual enrollment period to do so. That period runs every year from October 15 through December 7, and any changes you make during that time go into effect January 1.
Pro Tip: Mark your first supplement enrollment date on your calendar. Knowing exactly when your 12-month window closes helps you decide whether to switch now or plan for the annual enrollment period.
How to Switch From Advantage to Medigap
Moving from a Medicare Advantage plan to a Medicare supplement is a little more complicated. A 12-month window still applies, and missing it adds an extra step to the process.
The 12-Month Window After Enrolling in Medicare Advantage
If you want to leave a Medicare Advantage plan for a Medicare supplement, you have 12 months from your enrollment in the Medicare Advantage plan to make that switch. Acting within this window keeps the process simpler.
Health Qualification After 12 Months
Once those 12 months pass, you will have to health qualify to move from a Medicare Advantage plan to a Medicare supplement. You will also need to wait for specific enrollment periods to make the change, which we cover in the next section.
Key Takeaway: If you are thinking about leaving your Medicare Advantage plan for a Medicare supplement, making the switch within your first 12 months lets you skip the health qualification step.

Enrollment Periods that Control Your Plan Change
Even when you qualify to switch, you still need to make the change during the right time of year. Two enrollment periods matter most.
Annual Enrollment Period: October 15 Through December 7
The annual enrollment period (AEP) runs from October 15 through December 7 every year. You can use it to move from a supplement to an Advantage plan or from an Advantage plan to a supplement. Changes made during AEP take effect January 1.
Open Enrollment Period: January 1 Through March 31
The open enrollment period (OEP) runs from January 1 through March 31. This is another window you can use when moving from a Medicare Advantage plan to a Medicare supplement.
Pro Tip: Start reviewing your options before October 15. That gives you time to compare plans and make a confident decision once AEP opens.
Medigap vs Medicare Advantage Switching Rules at a Glance
Here is how the two switches compare during and after your first 12 months.
Side-by-Side Comparison
| Medicare Supplement to Medicare Advantage | Medicare Advantage to Medicare Supplement | |
| First 12 months | Switch any time within 12 months of first enrolling in a supplement | Switch within 12 months of enrolling in the Advantage plan |
| After 12 months | Wait for AEP (October 15 through December 7) | Health qualify and switch during AEP (October 15 through December 7) or OEP (January 1 through March 31) |
Why It’s Harder to Switch from Medicare Advantage to Medigap
The key difference is health qualification. Moving to an Advantage plan after your first year only requires waiting for AEP. Moving to a supplement after your first year requires both the right enrollment period and approval based on your health.
If you are considering Medicare Advantage, we recommend these steps:
- Note the date your Advantage plan coverage began.
- Review how the plan is working for you before 12 months pass.
- Contact our team if you are leaning toward a supplement.
Key Takeaway: Keep track of your enrollment dates. Your 12-month window, AEP, and OEP decide when and how you can switch plans.
Talk With Senior Benefits Plus Before You Switch
Switching Medicare plans is possible in either direction. Getting the timing right is what protects your options.
Recap: Timing and Health Decide Your Options
Your first 12 months give you the most flexibility. That window starts with your first Medicare supplement enrollment or with your enrollment in a Medicare Advantage plan. After that, moving to Medicare Advantage means waiting for AEP, and moving to a Medicare supplement means you need to health qualify and switch during AEP or OEP.
