Hi, I am about 85 pounds overweight and also worried that my insurance provider (UnitedHealthcare) won't approve my surgery. I have high cholesterol and high blood pressure. The surgeon's office staff told me to see if I have sleep apnea because if so that would probably clinch the deal. Well, I did and I do. Got a c-pap machine yesterday. Now that I have 3 co-morbidities, the surgeon's office can write up a letter of medical necessity to submit to UnitedHealthcare. We'll see if I get approved. Sure hope so! Good luck getting your approval.
