Frequently Asked

What is Medigap? +
Medigap (Medicare Supplement insurance) is a private policy that fills the cost-sharing gaps in Original Medicare. It pays the 20% coinsurance Medicare doesn't cover, plus the Part A hospital deductible and other out-of-pocket costs depending on the plan letter you choose.
How does Medigap work? +
The provider bills Medicare, Medicare pays its share (typically 80%), then sends the remaining balance to your Medigap carrier, which pays its portion based on your plan letter. You owe little or nothing at the point of service.
When can I enroll in Medigap? +
The 6-month Medigap Open Enrollment Period begins the month you turn 65 AND are enrolled in Part B. During this window, coverage is guaranteed-issue with no health questions asked.
Can I have both Medigap and Medicare Advantage? +
No. They are mutually exclusive. Medicare Advantage replaces Original Medicare with a private plan, while Medigap supplements Original Medicare. You must choose one or the other.
Are Medigap plans standardized? +
Yes. Plan G from one carrier is identical to Plan G from another carrier. Only price and rate-increase history differ between carriers.
Do I need a provider network with Medigap? +
No. Any provider that accepts Medicare must accept your Medigap policy, so you can see Medicare-accepting doctors nationwide without referrals or prior authorization.
