Do doctors offices have a responsibility to give you an idea of the cost of a procedure before you have it done?

I don't know if there is any law about it, but they should not hesitate to give you a cost. Especially if you have no insurance and will be paying out of pocket. If you have the procedure with no insurance, and no idea of how much it will cost, then, when presented with the fee, and don't have enough money with you, or in your checking account, then they are not wise to withhold the pricing info from you.
