What Is Medicare Medigap Insurance? 
Medigap Insurance -LRB- also known as Medicare Supplement Insurance -RRB- is designed to cover what original Medicare Part A & B does not cover . For example , with Medigap Plan F , it would pay all your co-insurance , deductibles and co-pays . There is also no network with Medigap Insurance so you can go to any doctor or hospital that you want . If they take Medicare they will take the Medigap Plan regardless of who the insurance carrier is . I would be happy to answer any other questions you have .
