wendizz - yes, I am still with Dr. Walker at the Logan IHC Budge Clinic. As far as I know, he's the only game in town, so I haven't looked elsewhere (nor had any reason to). I don't know their Medicare policy or his availability for new patients. Perhaps call their office using the link I posted earlier in this thread.
I DO know that I never have trouble getting in, although I have never had to change an appointment or have a non-scheduled appointment. All of my care providers are in the Budge Clinic (podiatrist, sports doc, x-ray techs, blood lab, pharmacy, etc.), so communication is excellent between offices, and I can tell that Dr. Walker reads my charts because he will bring up visits I had with different doctors without me mentioning it first. They have a pretty good electronic database over here at IHC, and all of my x-rays and notes with any doctor are immediately available to any other doctor.
Their nursing and office staff in the Rheumatology clinic is also excellent. I just started Enbrel a couple weeks ago. The staff almost literally carried me through the process, worked with my insurance, worked with Enbrel financial aid, and also gave me leads on non-profit financial aid groups to help with co-pays. It was only a couple weeks between telling them I wanted to try Enbrel and getting my first shot. I was also able to sit down with a nurse for a solid hour and go through the finances of Enbrel vs. Remicade, as well as a Q&A on Enbrel on all of my concerns. She then helped me administer the first shot with an office sample. When I call over there, they know who I am. I was very pleased with the whole experience and the education I received.
