From what I know, your BMI is not high enough to warrant insurance paying for it. It would be considered more cosmetic than for long term health. The insurance companies have all of this data and studies and know when they can save money over the long haul if someone is over 40 BMI
The LapBand is not a miracle cure. You have to work hard with this wonderful tool to make it work.
Whatever you do don't try for the 40 BMI, go the other way!!!
Good luck.
