No, he's wrong. Aetna doesn't require a BMI in the low to mid 40's for lapband. They have the exact same requirements for lapband or RNY or DS. Once they approve it, they leave it to you and your surgeon to choose what's best for you. It sounds like your surgeon has a preference for that. But he's mistaken about Aetna not approving it.
Aetna IS a stickler about a lot of other things, but not that.
