Sure, Elizabeth.
I was with Anthem from 07/2008 through 07/2009 and went through a denial/appeal/approval to get my Navigator CGMS. The initial denial was based on a lack of timely paperwork, even though my CDE had sent it THREE times between July and October. My appeal process was to actually call the extension of the woman who denied it (my nurse had come up with the phone number). This woman was not pleased that I was calling her directly, but within 15 minutes, I had convinced her that I met the requirements for the device and she gave me a ten-digit pre-auth code to give to Abbott and the DME supplier to get the device shipped. I had my CGMS in hand by November 4.
