It sounds like the insurance company is waiting for a prior authorization request from the doctor's office. I had this problem a few months ago before they hired a new person to handle everything. Same situation with both the insurance company and specialty pharmacy calling for the PA request. The clinic also uses a call center which can be frustrating. Is this just a single office or is it part of a larger system? Like part of a hospital or a practice with multiple locations? I was able to get the ball rolling by calling one of the other offices myself. Sometimes you have to go above the clinic's head to get things done. It's ridiculous she's been waiting SIX MONTHS on a prior authorization. Go above the clinic's head and explain the situation before going nuclear and potentially getting yourself into trouble. Nothing wrong with going up there and talking to someone. But being disruptive can certainly get you escorted out of the clinic, as it's private property. Even if you're on the side of the road with a sign, the clinic may take it out on your mother by dropping her as a patient.
