I have the BCBS HMO, went to see the surgeon, completed the paperwork with him and then received a call from the surgical coordinator telling me that the 6 month supervised diet was required along with a mental eval. I am getting the impression that this is a " canned response" from the office and they did not even submit anything to insurance. My insurance company told me that surgery was covered but did not mention any conditions. I have not received anything from the insurance denying the surgery. I have a BMI just under 40 but I am diabetic. I thought I would be approved without any issues. Anyone have the same experience?
