Difficulty getting started because of employer insurance

At the moment I'm in a battle with my insurance (Cigna) because apparently my employer has not allowed any form of diagnosis related to weight loss and obesity from the plan. I've received a referral from my primary to simply start the process with a weight loss management group for nutrition therapy as well as psych evaluations before finally meeting a surgeon. The problem is that even THOSE aren't covered so I haven't even met with a surgeon to get the final go okay for the surgery.

I'm basically stuck at step one and I honestly don't know what to do. I've met a brick wall and haven't found any luck finding information or feedback about anyone else that hasn't been able to walk through the door to start getting the help they need. I've only seen cases of people having an issue getting approved for the actual sleeve surgery.

What should I do? Any and all feedback and suggestions are welcome and appreciated.
