Has Anyone Had Any Experience with Cigna Insurance?

I called my insurance to see the the qualifications are for a breast redution. All they tell me is that it has to be  deemed medically necessary. It's like the try to beat around the bush. As matter of fact, they said that a breast redution was not covered but an reduction mammoplasty is.....isn't that the same thing? As anyone had any experience with filing Cigna when getting a breast reduction...or reduction mammoplasty?
