How Is Medicare System Funded? 
The Medicare system is funded by deductions from your payroll . So in large part , we have all paid into the system throughout our working careers . If your spouse did n't work , he/she is eligible anyway since you contributed . If you did not contribute , you can pay for Medicare or purchase insurance through the state or federal exchanges . Note : You still have to pay $ 105/mo for Part B when you go onto Medicare .
