3 month nutrition requirement-Self Pay

I am a revision from RNY to DS. I will be self financed as my insurance turned me down for this 2 years ago. I am back going through the pre-tests, etc. They have me seeing the nutritionist for the 3 months as before. My understanding previously is that the 3 month requirement is for insurance purposes. Since I am not going through insurance I asked if this was still a requirement. I have done all the other tests and have been cleared. I was told that I had to do the 3 month nutritionist. It doesn't make much sense to me since I am a revision, understand all the dietary requirements (also since I did the 3 month nutrition 2 years ago) and the last time lost 10 lbs. Needless to say I am not getting much in the way of true responses just "this is what you have to do". So I am doing it. My question is, does anyone know if I can get "denied" if I don't lose any or enough weight? I have stayed the same weight for 2 years (even the doctor noted that I am stable). I have terrible back issues (another reason for surgery so I can exercise and avoid back surgery) so I can't really exercise. I was down at my goal weight for 9 years, totally know how I gained the weight back (tragic family situations and I stopped paying attention to my food and exercise, typical...) and am ready for the surgery.

Does anyone have any thoughts/experiences where they were "turned down" due to weight loss or lack of? Given that I am getting on the scale every day, I know I am the same.

Any thoughts/insight would be appreciated.
