Accurate or not clinician time is typically billed separately, as are drugs, individual procedures, equipment, etc. Some stuff is rolled up but not that much; hospital accounting systems are quite comprehensive and structured in such a way to help them argue with insurance companies.

So the argument that the crutch is expensive because an MD handed it to you probably doesn't hold, the clinician files something, probably under a CPT code, and you were billed for that separately.

This depends on the service of course, you may see say a CT scan where the room time & tech etc. are rolled into one item, but the radiologist review is separate. So it isn't just people vs. equipment, etc.
