My 3 visits with Dr Zimmer were great. He was able to reduce my foot pain from an 8 to a 5. He ordered an MRI, and my insurance questioned it. They requested a peer to peer review, and it never took place. All of this happened over the holidays so delay was to be expected. My last communication with his assistant assured me that she would nag him and even put a note on his computer screen to remind him. I left 3 voicemails and sent 1 email asking if here was anything I should be doing with my insurance to help the process along, no response. If a Dr no longer wants you as a patient he should at least have the courtsey to let you know.
