I have a doctor that actually cares. If I had one that didn't, I would not stop until I found one that did. It's mostly getting the insurance to cover medications that they don't. The doctor usually spends the last hour of his day doing this, for me and other patients. You have to find a local doctor outside of a major city with less client base so they DO have the time. I am in the US. My deductible is very high but the medication I take is life sustaining and I can never pay for it. I have to do this every 6mo to a year: make an appointment and hope the doctor gets their way. Once they didn't and that is why I am at my current doctor. There is not much negotiating a patient can do calling the insurance themselves. They will just look and see you don't know what you are talking about. No matter how you complain about the symptoms, your financial burden, your family, or the fact of it being life-sustaining. Best to have a medical professional advocate. I have even tried with doctor letters and emails forwarded before calling. That is why I wonder what the doctor actually says that gets through.
