I have been researching this heavily in Arizona. So far, I have found that many of them cover bariatric surgery. Most will only cover gastric bypass. You have to read the Explanation of Benefits soooo closely. They don't specifically exclude sleeve under the topic of bariatric surgery, but then if you read further down under gastroplasty, laproscopic gastric sleeve procedure is specifically excluded. This really bothers me. They recognize it as an accepted procedure for medical necessity in treatment of obesity, but they refuse to cover that specific procedure under Obamacare. I am very, sad right now. I don't know what to do really. :/ I can't afford the cash to get the procedure, I really need it, and prefer the idea of sleeve over bypass for many reasons. I just think its really sneaky of them to try to hide that they don't cover it by not specifically stating it under the topic of bariatric surgery. :/
