Medicare sets the rate of payment and pays 100% under Medicare part A
...medicare pays 100% of the rate they pay which is less than most doctors or hospitals will accept. You or your supplemental are responsible for the balance. If you do not have a supplemental, most doctors and hospitals won't talk to you.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
