LifeWise....Any experiance?

I have lifewise insurance through my wifes work. WLS is considered an exclusion, but I was told over the phone that it can be considered if it is a medical necessity. I am planning on having the surgery done at OHSU. My mom had it done and has had great results. I have been to the lecture, and am now in process of getting my appointment with the nurse practitioner and dietician. Just getting all my records together now. Thanks for your help! Aaron
