Will Tricare Cover Vsg Soon?

I am still confused with the Medicare approval (?) of vsg. I gather that it's a state by state and case by case basis? I am curious now if Tricare will follow. I know some people in the wls world know how long it has take different insurance to approve different surgery types. Does anyone know how far behind Medicare Tricare was for other surgeries? Just trying to get an idea on how long I'll be waiting. If it's only going to be a few months I'll definitely wait to have it done by my civilian bariatric surgeon, otherwise I'll go forward to have it done at an MTF. I'm meeting with my surgeon tomorrow and plan to ask him as well, but I'm anxious for any info.
