Other industries have addressed that, no reason an ER can't as well.
If I go into Home Depot to buy a pipe wrench, they don't charge me one price if I have an emergency leak to fix at home, and another price if I'm buying for an upcoming project. And the same price at every HD, and comparable prices at other stores. Same with a tow truck, etc.
ERs and hospitals can have fixed prices for routine things, and set charges for the variable add-ons. Transparency is a good thing.
I think a rating system can be created for doctors and hospitals. It won't be perfect, but it should be better than nothing.
