How Many Standardized Medigap Policies Are There? 
In all but three states , there are 10 `` standardized '' Medicare Supplement , aka Medigap , plans available . These plans are known by the letters Plan A , B , C , D , F , G , K , L , M , N , and a High-Deductible Plan F . If you are looking for the policy with the most coverage , that will always be Plan F . That said , many people benefit from Plan G , which covers all the same items as F , other than your annual Medicare Part B deductible , which is just $ 147 this year . If you can save more than $ 147 a year in premiums by going with G , that may well be the best plan for your personal situation .
