I have BCBSAZ and i need to know what they require for a breast reduction to be deemed medically necessary. I am 20yr, 5'3 1/4"-5'4", 170 lbs and a size 36G. My BSA for the Schnur test is a 1.84. Looking to go down to a full D/small DD. Also, what are some of the steps required to start the process of a br? Some people went to their PCP others saw a PS first. Should I call my insurance first to see the requirements, or go to my dr of choice?
