BCBS??? I'm confused Please Help

Hi, I am in the pre-op stages of my journey to have Gastric Bypass. I have bcbs ppo. My question is when I was told I had to the 6month supervised diet, doe that mean I need my pcp to supervise this. I go to weightloss center where they weigh me every month. The Bariactric NP says that I have completed 2 of the 6mo. I really confused now. I know my pcp is in touch with with the center, does that count???

Can you tell me what state the blue cross is out of and I can tell you if it has to be your PCP vs the Bariatric Center.  Most BC polices do no allow the Bariatric Center to be where the 6 month supervised diet is documented 

I have Mountain State BCBS (West Virginia) I did my six month pre-op dieting with weigh****chers, but I had to go to my primary care dr once a month to be weighed and have him sign the form. Hope this helps. It is worth the effort to get approved, no matter how many hoops they put in front of you. My surgery was covered at 80% and most of my labs and pre-op testing were completely covered because I had met my deductible.
