Priority Healthcare Medicare - Process? Borgess Hospital?

Anyone recently go through the approval process through Priority Health Medicare? My BMI is 65. My PCP is not apart of Borgess, but its the closest Center of excellence which my insurance requires that I goto.

Im going to a Borgess Bariatric Seminar in Kalamazoo, in a couple weeks, I sure hope the approval process isnt long, I have spent too many years on this ride and have tryed many different routes. Have had Sleep Apnea for over 10yrs and have not been below 300 since the 90's no matter what I have tryed.
