My Dexcom CGM was denied by BC/BS of California this past March. I appealed and it was denied again. I appealed a second time and an independent review was initiated. Three physicians ultimately looked at my claim and medical records. Two of them voted for overturning the the insurance company's denial of the claim, the other voted against me. In any case, I just won the appeal and my CGM is now covered. I have had Type 1 for 8 years and wear an insulin pump.
