Earlier quoted context omitted.
most doctors in the US actually do not know about the prices of treatments as it changes based on insurance administrator/insurer, and then what the patient pays also have huge variability based on insurance administrator/insurer.
I get why they might not be able to tell you how much you'll pay because of your specific insurer, but why would the overall price of the treatment change with it? That seems bizarre.
Its scummy and fraudulent, but issuing a large bill to an insurer, then getting a much smaller check back is how medical billing works here in the USA. Having your insurance pay for a trip to the ER after a car accident would be $7k for them, or $84k for your car insurance, hence why one should carry a car insurance policy with good driver/passenger injury coverage :P
