Creed, when I talked to the bariatric center they said they wanted it in writing from BCBS fep that the 6 mon supervised diet was not required. I called BCBS fep back asking for this and they said I was given the wrong information by them when I had previously called. That I had to follow BCBS TX criteria and that it was required. It seems you can't even rely on info given by your ins carrier. I'll continue with the supervised diet and hope for approval when completed..
