New to Charlotte

Hey Everyone I am new to Charlotte and in the process of going through the 1st of many visits to SE Bariatrics.  I was wondering if anyone has encountered an exclusion on there employers plan and has succeeded in appealing it.  My employer (large employer) has stated that I am more than welcome to fight it.  Just seems that I thought if I went from a small employer to a large one my chances would be better.  Never thought I would be in the same boat.  Any words of encourangement?  Also has anyone succeded in applying for Medicaid or Medicaire to cover it?
