UHC

Im a City of OKC employee, and Im covered by UHC health Ins. There is an exclusion on policy for weight loss surgery. Ins will pay for everything leading up to surgery, but not the surgery itself. Its open enrollment at this time and I was thinking about switching over to BCBS but Im not able to afford all the deductibles. Can this exclusion with UHC be appealed? When I called UHC, a rep told me that surgery wasnt covered but it all depends on how doctor "words" it.....(didnt quite get that one)

Any suggestions on how to deal with this?

Thanks in Advance
