My insurance carrier is UHC Choice plus and my employer did not purchase the plan with the WLS approved.  When talking with a representative she told me to write a letter to the Medical Review Board to appeal for approval.  I included in my letter how much my comorbidities have cost them over the past 12 months which total just over $22K and the Gastric Sleeve is $25K.  I also included the National Standards for treating obesity.  I will keep you posted as to what I have found out.

 Did you ever get an answer? Who is your employer?
