What Is Medigap Plan C? 
There are 11 standardized Medigap plans , each designated by a letter -LRB- A , B , C , D , F , Hi deductible F , G , K , L , M , and N . The insurance coverage in each plan is different , and premiums are normally adjusted accordingly . Plan F happens to be the most comprehensive in terms of coverage , and will typically have the highest premium out of the 11 plans . Plan C has the same coverage as Plan F with one exception - Plan C does not cover Part B excess charges . It is a good idea to find a licensed insurance agent who is experienced in Medigap plans to assess your needs and objectives and review optimal solutions with you .
