My wife was a Clinic Administrator with 48 direct reporting staff and 13 physicians and I will tell you that the physicians have no idea what a patient is being charged in most cases.
We had a family member with a cardiac event (not a heart attack) in the hospital overnight for a total of 23 hours and the bill a decade ago was $34,000. The Cardiologist had mentioned later the advice of "just go to the hospital" and when I said the cost, even covered by insurance, was a concern and told him the figure, he was taken aback.
I write orders for outpatient IV antibiotics multiple times a week. This involves insurance, home care companies, visiting nurses, pharmacies, labs, and sometimes transportation.
For years, I at least tried to figure costs out, but I have given up. Almost all parties to the transaction have “hold harmless” arrangements where “estimated cost” is meaningless. None will provide that information to doctors.
