WRONG
No one SELLS anything as far as hospitals and doctor's offices. One it goes to collections, it gets WORSE for YOU, the debtor...becuase now, there is INTEREST to pay. If you do not PAY, you will then get SUED...which means you go to court and they evaluate your belongings (house, car, land) and see what you can do to pay off your bill. They can also GARNISH your pay check, usually to the tune of 25% of what you make.
Pay your bill....there is no way to avoid it. Your FUCKED.
