The pricing system is intentionally designed to be opaque so that everyone except the consumer benefits. It is not uncommon for a top surgeon to make 500-750K per year, nurses are paid well above the median and can make over 100K with overtime, hospital administrators, insurance companies... the way pricing and billing is handled protects all those interests.
Sounds like something you would want to fix, right? Well that too is complicated. Healthcare is one of the only sectors that is growing middle class jobs. A hospital is one of the only places someone with an associates degree and a certification can make 60K per year.
Furthermore, it is one of the only growing industries that provides many opportunities for women. Not many women want to move to Montana to frack shale oil.
Start socializing medicine and all that job growth and opportunity disappears.
It is a tough problem to solve. The utter irrationality of it used to drive me nuts and still does sometimes, but I prefer it to the alternatives.
