As an added tip, especially with Aetna, don't only look specifically for which "bariatric" surgeons are covered. Many surgeons who perform bariatric surgery are listed as "general surgeons." Your best bet would be to call Aetna and ask about a surgeon you are interested in to see if they are in-network. The surgeon I went to was not even included on Aetna's website, but when I called Aetna, they confirmed that he was, in fact, in-network.
