Medical Supplement Insurance, also known as Medigap, is private insurance that fills the gaps of Original Medicare coverage. Medigap plans cover part or most of Part A and B’s remaining health care costs, such as copayments, coinsurance, and deductibles.
Medigap plans are different than Advantage plans in multiple ways. First, they have higher monthly premiums than Advantage plans but lower out-of-pocket expenses. Additionally, advantage plans are to get Medicare benefits, while Medigap policies simply supplement your Original Medicare benefits.
