And if a provider keeps charging the same amount only now they actually get it because the law requires that insurance companies pay in certain instances?
My point is just that providers raising their prices to give insurance companies a bigger discount is a problem but getting a discount isn't itself flawed.
You keep outright ignoring my point, and then simply asserting that you don't see a problem. A bill from the provider shows a fake cost that they're demanding you reimburse them, and also a fake payment from the insurance company. Those are lies to make you think you are getting a benefit that you are not actually getting. That's called fraud.
