anyone get tt approved through CBA?

I am covered under an insurance plan administered through CBA.  They covered my breast reduction/lift no problem, without documentation of rashes, etc, even though they weren't that bad.  But, they decided the panni was cosmetic.  I am now trying again, with tons of documentation for rashes, back pain, trouble excercising due to panni, etc.  I was just wondering if anyone had been able to get a panniculectomy, or especially an abdominoplasty approved through them.
Thanks for your help.
