What Does Medigap Insurance Mean? 
Medigap insurance are health plans that cover all or a portion of the gaps in your Original Medicare -LRB- Medicare Parts A & B -RRB- coverage . Original Medicare only covers approximately 80 % of your healthcare expenses . While 20 % may not seem like a lot , it can add up to substantial medical bills very quickly . The big advantage of Medigap plans are that they can help you create a very predictable healthcare expense structure which is extremely beneficial for those on a fixed income . There are 10 different plans to choose from and each Medigap plan features a different combination of benefits , however , they are all standardized -LRB- meaning the benefits are the exact same under a given Medigap plan regardless of which company you buy it from -RRB- . Determining which Medigap plan is right from you and which carrier to apply for the plan through can be a bit more involved than some may realize . It 's not all about price as some may believe . You need to look at the carriers ' premium rating methods -LRB- community , attained , or issue age rated -RRB- , their rates , their rate increase history , their service history , and other factors . It 's best to consult with an experienced Medigap broker who can help you determine which plan and carrier will be most suitable to your desires , needs , and budget .
