Home Birth Insurance Coverage through AETNA

I am hoping to have a home birth with a CNM for my second child, and I am looking to find out if anyone has successfully been able to bill AETNA PPO for their home birth. I think I would to home birth even if insurance did not cover it, but we would definitely prefer if we could find a way to get it covered. I know that AETNA has a policy against HB, but rumor has it that some women have been able to get covered. Thanks everyone!
