I believe the doctor can do whatever he feels he want to do at this point. It's terrible, no it's downright HORRIBLE that he would because of money issues. I can not believe he wouldn't work out a payment plan of some sort or just try to work with in another way. These pain medication issues really upset me because they have NO clue just how painful RA is unless you have it. I do not know much about your issue but if it were me, I would start making phone calls and find out who this doctor's boss is or who is above him/her. They all have to answer to someone. I would also ask in all sincerity if there would be anything you could do. These people are supposed to be there to help medically and I would hope, if you are having trouble paying, financially.
