Excellent (and depressing) article. I didn’t think there was much else I could learn about hospital “overbilling”; I was wrong. For example: I had assumed that very specialized hospitals such as MD Anderson placed “extraordinary” profit margins only on very specialized medications and medical services, e.g., cancer medications and oncologists’ services – not on more standard medical services and commodities. Another example: I knew that “non-profit” hospitals were non-profit in only the loosest sense. This article really re-defines non-profit hospital.
