Did the dentist get paid for the x-rays?
no he said he would not charge me for the x-rays because it was there mistake
Even if he did no other work, it may be the X-rays that he is billing for/suing for & needs to be paid for. I know he said the ins. was fine but since they didn't pay, he still needs to be paid for whatever he did (ie X-rays). If he said he wasn't charging for the X-rays due to their mistake, I have no idea what he is suing for. He may be charging you for them after all and/or an appt. you went in for but decided not to have the work done since ins. would not pay.
As lealea asked previously, did you get it in writing that you would not be charged if there was a problem with your ins.?
