I paid cash for my surgery in Monterray, MX with Dr. Rodrigues $7900, and he does fills for I believe two years, but since it is not feasible to fly from West Virginia to MX for a fill, I plan to go to my Cigna approved doctor and have the fills done with Dr. Anaz in Fairfax. I paid for the surgery because I was not the full 100 lbs overweight, and I would have gotten there without intervention.
