How Is Medicare Advantage Funded? 
When you go on a Medicare Advantage plan , you are opting out of Medicare a & b for the time you are enrolled in the Part C Advantage Plan . Since Medicare does not have the liability of insuring you , they pay most of your premium for you . It 's estimated that they pay around $ 800 monthly to the insurance company that you choose . You pay little or no premium to the company plus your Part B premium .
