Do I Need Part C Of Medicare? 
You do n't `` need '' Medicare Part C , but you may choose to have it as your Medicare coverage . Medicare Part C is really known as the Medicare Advantage Plan . It acts like an HMO or PPO . Part C combines your Original Medicare Part A -LRB- hospital -RRB- and Part B -LRB- medical -RRB- , and usually Part D -LRB- drugs -RRB- . It 's important to note that if you have Medicare Part C -LRB- Medicare Advantage Plan -RRB- , you do n't need a Medigap Policy and ca n't be sold one to help supplement your health care . You can only purchase a Medigap Policy -LRB- Medicare Supplement insurance -RRB- , if you are still on Original Medicare Part A and Part B . There are a lot of moving parts to Medicare . Please let me know if I can be of further assistance .
