Frequently Asked Questions
What if I live in a state that doesn’t require under-65 Medigap?
Some insurers may still offer coverage voluntarily. Contact multiple insurers. If denied, Medicare Advantage is your best alternative.

Yes, typically. At 65, you can shop all plans with guaranteed issue. Premiums are based on age 65 rates, which are usually lower than under-65 rates.
Can I be denied Medigap for my disability?
Yes, in states without under-65 requirements. Even with a disability, insurers can deny coverage outside open enrollment or guaranteed issue situations.
Does ESRD qualify for Medigap?
ESRD qualifies you for Medicare, but Medigap rules are the same. Some states have special provisions. Check your state’s requirements.
