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.
