My doctor also asked for the same thing. They say it's for the "free" seminar, the support groups, etc. I think it's basically just to try to make up some difference because of what insurance will actually pay them (just an opinion though). I think too it helps weed out some people who aren't really serious and the doctors staff can spend hours working on filing with their insurance and misc. paperwork so that kind of would help insure that they are serious about having the surgery. I was a little leary of the fact that they were asking for the money but out of all the research I did on the doctor I couldn't find anything negative said about him. It was also kind of a motivator for me cause sometimes when I would start freaking out about my decision to do the surgery I would stick with it cause I had already paid my money.
