Can liposuction used to treat lipoedema ever be covered by insurance?

I had a weight loss surgery nine years ago, losing 190 pounds. My thighs have remained huge with ripply fat that hangs in a huge ridge over my knees. Diet and exercise do not help at all to lose this fat. As a result, my knees have become so painful and walking makes the skin flop back and forth. The skin under the folds tends to get moist and rashy at times. I was wondering if insurance ever pays for liposuction for lipoema.
