Tried to deny my rights to collect from my insurance company for a covered procedure. Once the insurance company notified office that the procedure was covered, the office dropped me citing " being unconfortable with rendering future service to me". This uncomfortableness came only 'after' the office was told that they had over-charged me, and that a procedure in progress was covered by y insurance!!
Great Dentist - lousy billing/insurance procedures. Take your chances.
Don't give up your insurance rights - even if you sign a statement - insurance will still cover if your coverage allows.
