Trying for the CGMS

well so for I have all my daily charts in for the pass 2 months, I have my reg Dr NOT the endo writing a letter of medical need to my insurance company..her Endo thinks the insurance company will not cover it so why waste his time....grrrrr. I have Minimed doing all the rest of the paper work and in a week everything should be turned into my insurance company from that time I was told it may take 2 to 6 weeks to see if its approved or denied, if its denied Minimed will do the appeal process for me. I m doing a lot of praying thats for sure.
