Well I do know how Medicare is funding and FICA is not the correct answer. Income taxes (general revenues) fund 41% of Medicare, payroll taxes 38% then premiums fund 13%.

"Medicare is funded primarily from three sources: general revenues (41%), payroll taxes (38%), and beneficiary premiums (13%)." http://www.kff.org/medicare/fact-sheet/medicare-spending-and-financing-fact-sheet/

Perhaps now you have learned something?
