Atena or Blue Cross
My husband had BCBS and it actually paid for WLS but we fond out just after submitting that it was excl.uded by employer. Now my husband has Aetna and it has WLS under their policy ,but then again the employer has excluded it. I have just gotten insurance with my own job in which mentions they approve of Surgery but haven't submitted yet. Ask theri HR specifically to let you see a summary of benefits documents (it is usually in a PDF form and they either have it online or they can email your BF or you the link)
Hope that helps and good luck
