Why Would I Need A Medigap Policy? 
Medicare Part A & Part B only covers about 80 % of the cost of your healthcare . In addition , the 20 % that you are responsible for does not have a limit . No max out of pocket or cap so if something major happens you could be left with a lot of very expensive medical bills . Millions of Americans age 65 and over buy a Medigap policy to cover what Medicare Part A & B does not . There are several plans to choose from but all Medigap Plans have a letter such as Plan F , Plan G , Plan J , etc. . If it does n't have a letter it 's not a Medigap Policy . I would be happy to answer any other questions you have .
