Guaranteed Issue Rights for Medigap: When You Can’t Be Denied Coverage
Last Modified: 10/05/2026 | Reviewed by Keith Armbrecht (NPN 634015)
Quick Summary
Medigap guaranteed-issue rights are federal protections that require insurance companies to offer you certain Medicare Supplement policies in specific situations, even if you have health problems.
When you have a guaranteed-issue right, the insurance company generally:
Must sell you an applicable Medigap policy
Must cover your pre-existing conditions
and
Can’t charge you more because of past or present health problems. (Medicare)
Key Facts
- Guaranteed issue is also called a Medigap protection.
- These protections apply in certain specific circumstances.
- Your health can’t be used to deny applicable coverage.
- Pre-existing health conditions must be covered.
- You can’t be charged more because of your health.
- You generally need to apply within a specific time window.
- You may need documentation proving your guaranteed-issue right.
- Not every event provides guaranteed issue.
- The specific Medigap plans you can buy can depend on your situation and when you became eligible for Medicare.
States may provide additional guaranteed-issue protections. (Medicare)
Common Situations That Can Create Guaranteed-Issue Rights
Federal protections can apply in situations such as when:
Your Medicare Advantage Plan Leaves Medicare or Stops Serving Your Area
You may have Medigap protections when your Medicare Advantage coverage ends through no fault of your own.
You Move Outside Your Medicare Advantage Service Area
Certain moves can provide opportunities to return to Original Medicare with Medigap protections.
Employer or Union Coverage Ends
Certain losses of employer or union coverage that paid after Medicare can create Medigap guaranteed-issue rights.
You Have a Medicare Advantage Trial Right
If you tried Medicare Advantage under certain circumstances and return to Original Medicare within the permitted 12-month trial period, you may have a guaranteed right to purchase certain Medigap coverage. (Medicare)
Your Medigap Insurance Company Has a Serious Problem
Certain situations involving the Medigap insurer, including coverage ending through no fault of your own or certain misconduct, may create protections.
How Long Do You Have to Act?
Guaranteed-issue rights have deadlines.
The exact timeframe depends on the event.
For example, in certain situations involving the end of Medicare Advantage coverage, Medicare says you may apply for Medigap beginning 60 days before the MA coverage ends and no later than 63 days after it ends. (Medicare)
Don’t wait until the last day to investigate your rights.
What Proof Might You Need?
Insurance companies may ask you to provide documents showing why you have guaranteed-issue rights.
Keep:
- Letters
- Notices
- Emails
- Plan termination information
- Employer coverage notices
- Other proof showing when and why your coverage changed. (Medicare)
Guaranteed Issue vs. Medigap Open Enrollment
These are different.
Medigap Open Enrollment
A personal six-month enrollment period when you’re 65 or older and Part B begins.
Guaranteed Issue
Protection created by certain qualifying coverage changes or events outside your normal Open Enrollment Period.
Video Explanation from Keith
When Medicare Supplement Companies Can’t Turn You Down
Keith's Take
Guaranteed issue can be incredibly valuable because it can give you access to Medigap when medical underwriting might otherwise be a problem.
But here’s the issue:
You don’t automatically have guaranteed issue simply because you want to leave Medicare Advantage or change insurance.
You need a qualifying event.
And there’s usually a deadline.
Before changing coverage, determine:
Do you have guaranteed-issue rights?
Which plans can you buy?
When must you apply?
That should happen before your existing coverage disappears.
