Banner Health Insurance ?

Hello! I am curious to see if any body has the Banner Health Employee insurance?  I work for another hospital that is being taken over by Banner.  Currently my insurance does not cover any WLS, but I know that Banner does with a $5000 copay. I am hoping to have surgery early next year, so I am trying to get a head start on any prerequistes now so that there won't be any delays later.  The new insurance will be effective January 01 and i want to have surgery in early March!! If anyone knows what requirements they have I would really appreciate the knowledge!!! Thanks In Advance, Samantha
