Even if you have good health insurance, hospitals "in your network" have a scam whereby doctors not in your network treat you -- and you're on the hook for megabucks.

It should be flatly illegal to do this.

@dangillmor I thought it WAS illegal to do that now - didn't the "No Surprise Billing Act (or something to that effect) recently come into force? They were talking about it on the news last year and basically it was intended to prohibit exactly the sort of thing you describe. Did I hallucinate that?
