I was denied by UHC too but for a different reason. I did meet the BMI requirement but didn't have 5 years of physician documentation of morbid obesity. I went to my PPO to talk about writing a letter in support of my surgery. She wrote the letter which included my diet history for the past 5 years, knee pain, previous hypertension, and GERD. The letter was included in the second appeal and I was approved within a week. I think including a letter from your PPO will go a long way in winning. I think insurance companies count on us quitting after the first denial. Don't give up!
