Help denied by Aetna

Dr Greenbaurm submitted my paperwork to Aetna and they are saying it was rejected due to no proof of Nutrition or Exercise program, I sent an e-mail to Dr Greenbaum, when I had my RNY in 2003 I was at 440 lbs and went down to 200 lbs in 2004 and remained there until 2008 and the started to gain went to original surgeon she did the endcop procedure to determine the stoma had stretched and then I started gaining, I was hungry all the time isn't that enough for Aetna, it was not me I provided daily food logs, what do I do to prove I should have revised to DS. Help!!!

What does Aetna policy state in regards to covering WLS?

My insurance co. Health Net made me to a medically supervised weight loss program for three months. That will give your ins. co. what ziethey are looking for, documentation.
Hope this helps,
