Choosing a Medicare Supplement (Medigap) plan can feel confusing, especially when it comes to understanding Medicare Supplement Guaranteed Issue rules.

These special protections allow you to enroll in certain Medigap plans without medical underwriting—meaning the insurance company must accept you, regardless of your health conditions.

Below is a clear and simple guide to how guaranteed issue works, who qualifies, and what to watch for.

What Is Guaranteed Issue?

Guaranteed issue rights—also known as “GI rights”—are protections under federal and state Medicare rules. When these rights apply:

  • A Medigap company must offer you certain plans.

  • They cannot charge you more because of your health.

  • They cannot deny your application due to pre-existing conditions.

  • Your coverage typically starts immediately after your prior coverage ends.

These protections help people who are losing certain types of Medicare coverage or making specific changes.

When Do Guaranteed Issue Rights Apply?

You may qualify for guaranteed issue in several common scenarios:

1. Losing Employer or Union Coverage

If your employer group plan, retiree plan, or COBRA coverage is ending, you qualify for GI rights to buy certain Medigap plans.

2. Your Medicare Advantage Plan Ends or Changes

You get guaranteed issue if:

  • Your Medicare Advantage (MA) plan leaves the service area

  • Your MA plan stops contracting with Medicare

  • You move out of your MA plan’s coverage area

  • Your MA plan violates its contract or misleads you

3. Dropping a Medicare Advantage Plan in Your First Year

This is known as the “Trial Right.”
You qualify if:

  • You joined an MA plan when you first became eligible for Medicare Part A at 65

  • You decide within the first 12 months that MA is not right for you

  • You want to switch back to Original Medicare and get a Medigap plan

4. Dropping a Medigap Plan to Try an MA Plan

Another “Trial Right” applies if:

  • You had a Medigap plan

  • You switched to a Medicare Advantage plan

  • You decide within the first 12 months to switch back

You can re-enroll in the same Medigap plan you had before—no underwriting.

5. Your Insurance Company Goes Bankrupt

How Long Do Guaranteed Issue Rights Last?

GI windows vary depending on the situation, but most are:

  • 60 days before your coverage ends

  • Up to 63 days after your coverage ends

If you miss the window, you may need to go through medical underwriting.
