Hi, sorry you are having such a problem, my AARP provider is United Health Care, I am in Maryland, my doctor is in Va. he takes both medicare and AARP United Health Care. In this area, most Doc's who take medicare take AARP UHC, this is due to the fact that most of there patients are either senior's or disabled or in my case both.
If AARP UHC is available to you I would take a look at it, and all others available to you that your doc accepts.
