I have been researching the hell out of this myself. I have 30% service-connected, go to the VA Murfreesboro, TN. You qualify for BMI for sure. You have to ask you PCP (Primary Care Physician) to be refered to the MOVE program. You must be apart of the MOVE program for 6 month and prove that you are going to try. I think they require a 5% weightloss during the 6 months. Depending on your doctor and the MOVE people you may get your surgery right after you "graduate". There are only 12 VA hospitals that perform the surgery and one is the VA Medical center in Charleston, S.C. Not sure what any of the others are.
I have an appt. on the 20th and will ask to be put in the MOVE program and for the surgery. Fingers crossed!
