Federal Blue Cross/Blue Shield Basic Option

I had my 1st app. with my bariatric surgeon last week.  My BMI was 37, and I have 2 comorbidities.  The new 2011 BC/BS requirements state I must have had a BMI of at least 35 for at least 2 years.  My BMI has been between 30 and 33 for most of the previous 2 years. Does anyone know how I might still obtain approval? Thank you!
