I keep getting hospital bills from mom's four stays last year. the thing is, none of these bills explain what the charges are for. They just list a total and what Medicare and her insurance didn't pay from that total. How do I know how the total was calculated if there's no itemized list of charges? Seems rather unfair to me. I mean you wouldn't accept a bill from say, your mechanic that just said "pay me $1400" without listing what he's billing you for, no?
