Can Liposuction be covered by my MSP if my breast reduction is covered?

Hello there, I am currently going through booking to have a breast reduction, and abdominoplasty. I am a weight loss human, who has gone from 300 to 170 ect ect. Reason I am getting the breast reduction is that my back goes numb, ALL THE TIME. I need side liposuction. They say that this part is not covered and must pay out of pocket. Can Lipo ever be covered? How much proving do we have to do to link it, or is it just never ever covered?
