Anyone have benefit planners insurance

I tried posting this a while back and didn't get much of a response. My husband works for station casinos and has the ppo benefit planners/sierra healthcare options. I was wondering if anyone had that same insurance and got the surgery approved. They say it's a exclusion but Dr Atkinson is listed in the provider book.  Medicare is my secondary and they cover it but I was wondering about the other can't seem to get a straight answer when I call the insurance. Thanks for any help.
