It is just not these indecipherable codes on the bills. I typically get explanation-of-benefits that runs like, "X-Ray radiology 800$, Paid by insurance company 100$, discount to insurance 685$, you owe them 15$". Any one without an insurance will be billed 800$. No body would pay such an insane bill. They will sell it to some debt collector at some 20 cents a dollar. The bill collector would hound the patient, add all sorts of fees and penalties and dun payments. About two thirds of the bankruptcies in USA are due to medical costs. If the lab billed honestly and charged 150$ for uninsured, 100$+15$ copay for insured, things will not spin out of control this badly.
Another thing is so many different people bill you and you have no idea. My wife had a surgery and we have bills rolling in for some four months after the procedure. Random doctors, labs, hospital departments, practices are billing us. For things that you don't understand at all. For things like rent for corridor space the gurney was parked on before entering the Operating room. They would glorify the corridor space as pre-op waiting area or some such jazzed up name. This on top of a per day rent for being inside the hospital.
The next step is going to be every doctor carrying an RFID detector and every patient tagged with an RFID tag. The machine will record all the patients the doctor passed by in the corridor and he/she can bill them all for looking at them.
