First, you need to find out if you will be required to do the 3 month diet plan, or six month. I did the six month, and after all was submitted, I was approved in two weeks. Just so you know the tme line...Info Meeting was Jan/08 and restarted 6 month diet plan (Dr's nurse did not record all the previous weigh-ins) Finished June, Submitted in July, Surgery Date in August. So, it is not a real fast thing. Do you have your surgeon yet? And have you talked this over with your PCP? This is all so important. But the most is what Aetna requires for you and your plan.
