This why some physicians refused to take WC. That sounds disgraceful to the patient but the bottom line is WC is a terrible pain in the butt for everyone who deals with them in one form or another. They are difficult to get a precert from for a med, test or procedure as they don't return calls. Once you get a precert, they are notorious for no pay/slow pay. There are other ins. companies that pull the same thing. It is sad to tell a potential new patient that their ins. isn't worth the paper it is printed on and they will need to pay cash, up front, or find another physician who is part of a large group that is willing to chase the companies for their money or absorb the loss.
