I have Aetna/Healthlink insurance, I was wondering if they are good at covering Breast Reduction surgery?

Hi, I had a consultation last week with a plastic surgeon.. He seems confident that my insurance will cover my reduction surgery. He said he can take 1000 cc of breast tissue out no problem. I'm currently a 40F and would love to be a large c.. I have back and neck pain, rashes under my breasts, headaches& the shoulder bra strap grooving. I also have Aetna, Healthlink Meritain insurance. I just want to know if they are good at covering breast reduction surgerys, and if you think I would qualify? Thanks!
