I have BCBS fed basic also. The bariatric center I went to said it does not require 6 mon supervised diet but since I reside in Tx and having surgery in Tx then I had to follow BCBS Tx plan and it requires the 6 mon diet. I've since started the 6 mon diet with my PCP. I'd love to know if this is incorrect. I'd much rather have my surgery now than wait 3 more months completing the diet.
