Idiotpathic Intracranial Hypertension and 6 month diet being waived for insurance.

Hello, I am looking to get weight loss surgery which my neurologist said is the best option for me. I have PCOS(Polycystic Ovarian Syndrome) which makes it extremely hard for me to loss weight. I have been diagnosed with Idiopathic Intracranial Hypertension, my neurologist is worried about me losing my vision and said and had a significant amount of fluid on my brain causing a lot of strain on my optic nerves causing my vision changes and loss of vision. I have pain, pressure and headaches all day long. I can't really enjoy anything because of the pain and now I am worried about losing my vision. I have insurance through Wells Fargo which is BCBS Anthem of GA. They require you to do a six month diet. My neurologist said that I should not wait that long to have weight loss surgery as this will help the IIH and PCOS. I called my insurance today and they agreed that it was a serious issues and could talk with my neurologist about waiving the 6 month diet plan. I already have my appointment scheduled for pre-op so hopefully they can get it waived and my psych eval is on Sept 6th so after that hopefully I can schedule surgery. I really hope they see the urgency with this issue as I don't want to do any further damage to my eyes and my neurologist agrees. Has anyone else been through the same issue and getting approved for WLS through insurance? Or experience the same issues?
