I have bcbs originally told in Nov nothing was required preop but in Dec I was informed I had to do a 3month diet (new requirement).
I also had to provide documentation of previous diet attempts,exercise programs, primary doctor recommendation letter and a statement that you have not smoked for 6mos or substance abuse for 1year. Unfortunately, I saw primary timely mid March but at time of my consultation the documentation had yet to arrive. Slight set back but I just plan to continue calling until it is submitted to avoid further delay in the insurance review process. My goal is to have surgery late May.
