Where Does Medicare Get Its Funding? 
A quick look at your pay stub will show you the source of most of the funding for Medicare . If that funding proves inadequate then congress will have to decide what to do next . Medicare is fully paid to all citizens who have 40 good quarters of FICA contributions or meet certain other qualifications dealing with disability . When you select Medicare B and/or D , then you will be charged an additional amount to cover the cost of that benefit .
