Empire Blue EPO coverage for gastric bypass

My surgeon has confirmed that my insurance does cover the gastric bypass surgery.

I have Empire Blue EPO plan.

I am wondering what the phrase below means in regards to the approval process since it does not specify a time period,

"AND The individual must have actively participated in non-surgical methods of weight reduction; these efforts must be fully appraised by the physician requesting authorization for surgery..."

I have the same insurance and have an appointment with the bariatric doctor in February.  Did you get an answer to your question?  Did you pursue the surgery?  Hoping for information so I am prepared for my visit and have the appropriate level of information to support my case.

Thanks for your help!
