Categorically, unequivocally wrong.
Hospitals cannot just make up charges. They cannot bill you for procedures/tests/services you did not receive (and if they do, you are not "legally obligated to pay it").
I know the anti-US healthcare circle jerk is pretty strong here, but we don't need to just make things up in order to prove a point.
Unless they're a small operation, I don't know that they'd have any direct visibility into the billing/insurance/finance side of the operation. Maybe that is the issue? I don't know how to combat that in a large hospital setting.
The one time I had surgery I ended up getting 3 separate bills for varying amounts, but any time I asked for documentation about a given procedure or test it was provided in writing well before the due date of the bill.
Hyperbole much?
They can charge you for services / products rendered and which aren't covered by insurance, and they can charge any price they want and you're legally obligated to pay it. Of 3 times I helped my parents with processing their hospital bills, it was over $10K in non-covered expenses each time.
Yes, you are legally obligated to pay for services rendered. I think you'll be hard pressed to find someone to argue the opposite, though.
For example once my wife had to go to the er and we'd taken great pains to know ahead of time what hospital was covered best under our insurance. Yet the bill contained test services performed in he hospital that were not covered because a room in the hospital was operated by a separate lab company that didn't accept our insurance. There was literally no way for us as consumers to know that one type of blood test regularly covered by our insurance in a covered facility would go through the magic door into an uncovered facility. Price inflation and surprise bills are emergent properties of the system and that needs to change.
I am all for consumers having choice and taking personal responsibility for their care but our healthcare system makes that effectively impossible.
Reading your previous statement literally (and I saw no reason to read it in any other way), it meant that a hospital could charge you for buying an elephant and you'd be legally obligated to pay.
And you're complaining about other people using hyperbole?
As a US citizen, I'm happy to have an increased tax burden for legislated vacation/holiday days and 20% of the population not having medical bills they can't pay for.
