Only for billing cost of procedures. It's still a mess.

Did you know that hospitals make money by using name brand medications? They will get a contract with a brand, like Motrin, and charge you full price at $8 a pill. Then Motrin will will evaluate how much the hospital used and give them a big rebate to bring the hospital's cost down under $1 per pill. You can literally buy a bottle of ibuprofen for what they charge for a single pill, but of course in the name of safety (and really kickbacks too) they won't allow the cheaper outside medication. It's effectively an internal monopoly.
