To answer a few questions:
I did the 3 month option. I met with a nutritionist that works in my surgeon's office. We did a lot through email. I did weigh in with them when I had an appt. (My surgeon's office employs the dietician and a psychologist for the psych eval.) Aetna required that I submit 2 year weight history...which I didn't even have a PCP sent everything from my OBGYN as I've had 3 babies in the last 5 years. My surgeon required a cardiac clearance which I had to have an echo for and a stress test. Surgeon also required pulmonary clearance and of course I had to have a sleep study for that. Surgeon required a letter from my PCP and a scope. I managed to have all the tests finished in about a month...it was busy though. They submitted to Aetna and it took about 2 weeks which I was told is fab b/c it's the end of the year and of course we ran into Thanksgiving.
I thought this process would be much harder...I still can't believe it was so easy. So now I have my team meeting on 12/9 with preadmission testing and surgery the 28th! I still am in shock that it is really going to happen but I can't WAIT!
