I believe you, but I know my local hospital milks the hell out of government paid medical care. They know what is automatically paid for and they always perform those tests. Completely unnecessary x-rays and CT scans. I watched them order an x-ray on a kids hand because it was poked by a pencil. No visible mark. I'm not exaggerating even slightly.  For reference, I was volunteer first responder, and would do ride-alongs with the ambulance company. We spent a ton of time in ER hallways. My hospital is poor and relatively slow, so maybe that's the difference though. Anyways, sorry to sidetrack.
