anyone have any experiences with fidelis insurance?

whether good or bad, im curious if anyone has had any experience with trying to get the sleeve with fidelis. i know they approve rny and the lapband, but not the sleeve directly as they dont recognize the new 2010 code 43775. but they do have an open restrictive code 43843 that they have sometimes approved and im wondering if anyone has tried that with them for the sleeve. code 43843 specifically says "gastric restrictive procedure, without gastric bypass, other than vertical banded gastroplasty". they also approve code 43845 which is bioliopancratic bypass w/duodenal switch, which basically is the sleeve with a bypass. and im wondering if they approve that code can i only have the dr do the first half of that procedure (the sleeve) without the duodenal switch (the bypass). thanks in advance, its appreciated.
