The trouble is even if the price list says $500 for something, they'll charge you $8000 for "general classification" and $2000 for a Tylenol.

I have a remote heart monitor at my bedside that, upon pressing a button, wirelessly retrieves data about arrythmia incidents from my implanted defibrillator and sends any incidents to the hospital. Every time I hit the button, even if there are ZERO incidents for them to review, I get hit with a $300 bill for some "general classification". So I hit the button less often than I'm supposed to.
