The "dotors" I know don't do it - no. They don't even work in hospitals for the most part. I don't mean every doctor does it, I meant a doctor - at least one or two - in every county in the U.S.A. does.
I'm sure a lot of the time the hospital administration itself is pressuring otherwise moral and correct doctors to run extra tests and over bill. Thats why a for-profit health care system is a lousy idea. ESPECIALLY one that is insurance based
