Medigap Guaranteed-Issue Rights in Texas
Some coverage changes give you the right to buy Medicare Supplement insurance without health-based denial.
These are called guaranteed-issue rights. They can protect you when qualifying insurance ends or when certain Medicare Advantage trial rights apply.
The event, application deadline, and Medigap plans available to you all matter.
Quick answer
- When: Enrollment protections depend on your situation.
- Health questions: They may apply outside protected periods.
- Before switching: Confirm approval and start dates.
What does guaranteed issue mean?
Guaranteed issue is a legal right to purchase certain Medigap policies without medical underwriting being used to deny you or raise the premium because of health.
It differs from the one-time six-month Medigap Open Enrollment Period.
A guaranteed-issue right does not necessarily let you choose any plan letter.
Federal rules identify different plan choices depending on the event and when you first became eligible for Medicare.
When a Medicare Advantage plan ends
If your Medicare Advantage plan stops serving your area, terminates coverage, or you move out of its service area, you may qualify for a right to buy Medigap when returning to Original Medicare.
Save the plan's nonrenewal or termination notice.
A routine Annual Notice of Change listing premium or benefit changes is not the same as a plan termination.
Read the actual notice to determine whether you are losing coverage.
Losing certain employer or other coverage
Some people qualify when certain employer or union coverage that supplements Medicare ends, or when a Medigap insurer becomes insolvent or coverage ends through no fault of the insured.
Texas also recognizes certain protections for people who lose Medicaid because of a change in financial circumstances.
The exact right depends on the type of prior coverage and reason it ended.
The first Medicare Advantage trial right
If you joined Medicare Advantage when first eligible for Medicare Part A at age 65 and decide within the first 12 months to return to Original Medicare, you may have a trial right to purchase an available Medigap policy.
This protection is tied to the first-year trial circumstances, not simply to any decision to leave Medicare Advantage years later.
Coordinate disenrollment and Medigap effective dates carefully.
The second Medicare Advantage trial right
If you dropped a Medigap policy to join Medicare Advantage for the first time and decide within the first 12 months to switch back, you may have the right to return to your former Medigap policy if the same company still sells it.
If that policy is no longer available, other specified Medigap choices may apply.
Keep proof of the old policy, the first Medicare Advantage enrollment date, and the date you leave the plan.
Which Medigap letters are guaranteed?
For many common federal guaranteed-issue events, people first eligible for Medicare before January 1, 2020 may have access to Plans A, B, C, F, K, or L.
People newly eligible on or after that date generally have Plans A, B, D, G, K, or L as corresponding choices.
These lists are not universal to every right.
Trial rights can permit different choices, and state-specific rules may apply.
Plans C and F generally are not available to people newly eligible for Medicare on or after January 1, 2020.
How long do you have to apply?
Many federal guaranteed-issue situations permit an application starting 60 days before qualifying coverage ends and continuing no later than 63 days after it ends.
However, the precise deadline depends on the event and may run from a notice date in some circumstances.
Do not rely on a single deadline for every situation.
Verify the applicable window in the Medicare.gov Medigap buying guide and the actual coverage-ending notice.
Submit the application and supporting proof promptly.
What documents prove your right?
Keep insurer letters, Medicare Advantage nonrenewal notices, employer termination documents, prior Medigap policies, and records of enrollment and disenrollment dates.
A company may request copies to confirm eligibility.
When applying, explicitly tell the insurer that you are using a guaranteed-issue right.
Ask which plan letters qualify, the last date to apply, and when the policy can begin.
Texas under-65 considerations
Texas generally provides a Plan A open enrollment right for people under 65 who qualify for Medicare through disability.
Different protections apply to beneficiaries with ESRD or ALS, and eligible people receive another opportunity when they reach 65.
These state rules are distinct from the event-based federal guaranteed-issue protections.
Confirm which rule applies before submitting an application.
Frequently asked questions
Does any lost insurance create guaranteed issue?
No. The kind of coverage and the reason it ended determine whether a right applies.
Does a Medicare Advantage ANOC mean my plan is ending?
No. An ANOC can report changes without terminating coverage.
Can I buy Plan G with guaranteed issue?
For some qualifying rights, yes, particularly for people first eligible for Medicare on or after January 1, 2020.
Check the specific event.
How many days do I have?
Many events have a 63-day post-coverage window, but the precise deadline depends on the event.
Can I be charged more because of health?
An insurer cannot use health history to charge more when an applicable guaranteed-issue right protects the purchase.
What proof should I keep?
Save written coverage-ending notices, prior policy information, and Medicare Advantage enrollment records.
