Is open surgery better than liposuction for gynecomastia?

Hello, I have suffered from massive man boob problem since puberty, and now I am having them removed. I consulted a gynecomastia surgeon last week who said he will remove most of the glandular tissue under my chest by making an incision at my nipple. He also said that he does not practice liposuction, because that falls more into cosmetic/plastic surgery.

My worry is should I consult another surgeon who does liposuction for men? I want to do this once, and get rid of as much fat in my chest there is, and I just want to know the best course of action. Will liposuction remove more fat in my chest than surgery.

… My insurance covers 100% of the cost if I go through my first surgeon, because the gyno I have can be classified as a health problem. If you tell me to go to another surgeon who does lipo, will my insurance cover that surgery too?
