I have seen the same doctor for over 20 years, 10 pre medicare and the last 12 under medicare, with a secondary insurance. I have not seen any change at all in the time he spends with me, or my care and treatment. Actually, as I have aged, I have needed to see him more and receive more attention the last ten years than in the first ten. I have had couple of issues that required additional time from him, and he spent as much time as we needed.
