I have Tricare and they took less than one week to approve the lap-band®. This was in mid December. I could have had surgery on January 4, after my pre-op diet but I decided to put it back one week so I can at least enjoy Christmas dinner. From my initial visit with my primary to ask for the referral, to my surgery date, it only took about 1 1/2 months. It happened so fast that I didn't even really have time to let it sink in. I guess that is a good thing.
