Oh, and that bill is probably gonna be full of medical coding mistakes too. Tests and procedures and all kinds of things marked up, put in the wrong category, and so forth. Expect to have to wrestle the insurance and the hospital for corrections.
I've had to do that once. I got denied short term medical insurance because they said I had diabetes (this is before Obamacare).
I've never had diabetes. I called my doctor and it turned out they coded one of my visits wrong and said I had diabetes, and it had been in everyone's system for at least a couple of years. Wonderful. Got it fixed, at least.
