Based upon my research, I'd guess there are some rare cases in which insurance has paid for a SG, but we're talking a fraction of a percentage. Many people with functional jaw issues can't get insurance coverage for bimax/LF1/BSSO, and the chance of a SG covered would be even less so I'd think. I almost guarantee you'll need to pay out-of-pocket. Once you come to terms with that, you're one step closer to accomplishing it.
