Is Medigap Part C? 
No , technically it 's not . Part C is also referred to as Medicare Advantage . So , when people are deciding on coverage they will either go the Medigap Plan route or the Medicare Advantage route . Medigap Plans cover what Medicare Part A & B do not and there are a lot of plans to pick from . For example , with Medigap Plan F , you would have no coinsurance , no deductibles and no copays . So , you budget the monthly premium that works for you and then you do n't have to worry about large out of pocket medical bills that come when you do n't expect it . Medigap Plans also do n't have a network so you can see any doctor or hospital you want . If they take Medicare , they will take the Medigap Plan regardless of who the carrier is . I would be happy to answer any other questions you have .
