Medigap (Medicare Supplement) is offered by private insurance companies to help fill the “gaps” Medicare doesn’t cover, such as copayments, coinsurance and deductibles. Generally, anyone with Medicare Parts A & B is eligible for Medigap.

Plans are assigned letters A through N, and are not to be confused with the “parts” of Medicare, such as Parts A & B. Each Medigap policy plan must offer the same basic benefits, no matter which insurance company sells it. For example Plan K from insurance company ABC must offer the same benefits as Plan K from insurance company XYZ.
