Is Medicare Part C The Same As Medigap? 
No . Medicare Part C is Medicare Advantage coverage - these plans work similarly to traditional under 65 health plans -LRB- meaning you can be responsible for coinsurance , copayments , deductibles , etc. -RRB- . A Medigap plan -LRB- also known as Medicare supplement plans -RRB- works WITH original Medicare -LRB- Parts A & B -RRB- to fill the `` gaps '' that it does n't cover . Original Medicare covers about 80 % of your healthcare expenses . A Medigap plan can cover a portion or all of the other 20 % , depending on which Medigap plan you get -LRB- there are a total of 10 different plans available - A , B , C , D , F , G , K , L , M , and N -RRB- . Medigap plans do not restrict you to networks , you do n't need referrals to see specialists , and any doctor that accepts Medicare will accept the Medigap plan . You can also apply for a different plan at any point throughout the year -LRB- if you want a different carrier or different benefits -RRB- , and they are guaranteed renewable !
