Earlier quoted context omitted.
The prices don't change in a supermarket if you edit your shopping list, eh? A hospital can't predict everything a patient will need (their shopping list), but they should be able to account for the cost of each procedure/drug/test/bandage/etc... eh?
The problem is a lot of that isn't deterministic. There's a lot of "If Then" statements that aren't easy to price ahead of time. Like, your procedure is very different if your doctor decides they could use a specialist consult.
The necessity of the specialist consult may be unexpected, but it doesn't follow that the cost of it should be secret or obscure, eh?
The intrinsic unpredictability of health care isn't an excuse for additional unpredictability of cost.
