Tyler Haskell · Answer

The short answer is yes!  Most people think they have to wait until the annual enrollment period to change, but that is not the case.  You can indeed change your supplement plan any time.  To be able to change plans, in most cases you are going to need to pass the underwriting criteria for the new company or plan.  Most companies require you to answer about 15-20 health questions.  Most companies will also check your medical claim history and run a prescription drug history report.  If all is well and you pass, you can switch.  

Some states have whats called the Medicare Birthday rule and this allows you to switch plans around your birthday without passing medical guidelines.  Just google your state and medicare birthday rule to find out the exact details of your specific state, because some states are different.

You can apply to change your Medicare Supplement plan at any time, but outside your initial enrollment window you'll have to go through underwriting and could be declined based on your health history. That's why I always advise my clients — don't cancel your current plan until the new one is approved.

Changing Medicare Supplement (Medigap) Plans
The short answer is: not always freely — it depends on your situation and timing.

Guaranteed Issue Rights (Best Time to Switch)
You have the strongest protections during specific windows when insurers must sell you a plan at the best available rate, regardless of health:

Initial Enrollment Period — the 6-month window starting when you're 65+ and enrolled in Medicare Part B. This is the best time to buy any Medigap plan.
Special Enrollment Periods — triggered by specific life events, such as losing other coverage (employer plan, Medicare Advantage, etc.).


Outside of Guaranteed Issue Periods
Outside those windows, you can technically apply to switch plans at any time, but:

Insurers can use medical underwriting — meaning they can review your health history and deny you coverage or charge higher premiums based on pre-existing conditions.
Only exception: A few states (like New York, Connecticut, Massachusetts, and California) have stronger consumer protections that allow more open switching.

Kristen Skinner · Answer

Yes you can. However, you have to go through medical underwriting. Which often times will get you a higher premium or the company will decline you altogether.

Rich Baker · Answer

Yes, unlike Medicare Advantage, Medicare Supplement plan changes are not limited to two and a half months from October to December each year. HOWEVER - unless you have a guaranteed issue window, you will have to undergo medical underwriting if you don’t have a guaranteed issue window available to you.

You can, but approval is not guaranteed. You will need to go through the health underwriting questions. Once you have completed this process, you could be approved and see what premium they offer you or you could also be denied.

Yes, you can apply to change Medicare Supplement (Medigap) plans at any time, but in many cases you may have to answer health questions and could be denied coverage unless you qualify for a guaranteed issue right.

YES, BUT THEY MAY BE MEDICALLY UNDERWRITTEN WITH PREEXISTING CONDITION CLAUSES. YOU WILL HAVE TO WAIT UNTIL OPEN ENROLLMENT TO CHANGE YOUR PART D DRUG PLAN.

Chuck Winslow · Answer

Yes — technically you can apply to change Medicare Supplement (Medigap) plans at any time during the year.

However, whether you are GUARANTEED acceptance is a completely different story.

In most states, once you are outside your initial Medigap Open Enrollment period or a guaranteed issue situation, insurance companies can usually require medical underwriting.

That means they may:
• Ask health questions
• Review medications and medical history
• Charge a higher premium in some cases
• Or even decline the application altogether

This is one of the biggest differences between Medicare Supplement plans and many Medicare Advantage plans.

Now here in Indiana, there is something very important called the Indiana Birthday Rule.

The Indiana Birthday Rule allows Medicare Supplement policyholders to switch to another supplement plan with equal or lesser benefits around their birthday each year without medical underwriting in many situations.

This is an incredible protection that many seniors don’t even realize they have.

That’s why reviewing your coverage regularly matters so much. You may be paying too much, have outdated coverage, or qualify for better options without realizing it.

I help seniors review these situations every day and explain their options in simple terms so they can make informed decisions — always at no cost.

Daniel Salzman · Answer

No, If you want a Medicare supplement the best time to get it is during your IEP, that means when you are turning 65 for the first time. You have a seven month window to get it. When you get it during this time you do not need a underwriting to get approved . if you want to switch you can during your first year at any time but after that you will need to pas underwriting every time you want to change. If you have a new illness and really do not like your supplement, then it may be worth exploring Advantage plans.
