What The Difference Between Medigap And Medicare Advantage? 
Medigap and Medicare Advantage are as different as apples and oranges . Medigap , also known as Medicare supplement , is designed to work in conjunction with original Medicare . Your original Medicare plan has no networks but does have deductibles and coinsurance that can leave you owing several thousand dollars . Medicare Advantage -LRB- formerly known as Medicare Part C -RRB- is a privately managed Medicare benefit offered by insurance carriers . With Medicare Advantage plans you have network providers , lower premiums than Medigap , and significantly higher out of pocket .
