I was charged $960 for a brace. They agreed to take $300 for it when my insurance wouldn't cover their fee. The $300 was agreed upon between myself, them and the insurance. Then 6 months later I get a legal collections letter from them for $660! They are either incompetent or they are just hoping that I'll be scared by the letter and pay them money they agreed was not due to them. This firm is a rip-off firm. They are operating under the assumption that health insurance companies just pay whatever is asked - and that is no longer the case.
Watch out for these people. And Doctor Offices, please stop using these people!
