Feeling kind of blue

Hello, Can anybody who has Cigna HMO - Open Access please let me know if they cover the open RNY? I called and on the phone they tell me as long as it's medically necessary, but when I go to the website, it says if the benefit plan doesn't have an exclusion and I looked at my paperwork and mine does. I'm very down as I definitely don't have the money to self pay and I so need to have the surgery. If I can't have the surgery, I have no more hope. Wendy Troyer
