Coventry Carelink Tier 1

I am currently in the process of trying to get information from my insurance company and this is not an easy task, dealing with them. I have Coventry One, Carelink Tier 1. The problem I am having is finding an approved provider. I go on their website and there are Bariatric Surgeons listed, but when I call they tell me the only one approved is a state away;. I just don't get it. Bariatric surgery isn't possible for me at all if this is true, as it is a 4 hour drive for me. Has anyone had any experiences with Coventry One, specifically the Carelink Tier 1? I'm thankful for coverage, but it won't help me if I have to travel that far. 

HI, did you ever figure anything out about this? Thanks
