Breast asynmetry after reduction - could I get a third revision covered by insurance? (Photo)

I got a Breast Reduction (2nd) late last year and I was really happy with the results but noticed that one was a little larger than the other. I wasn’t worried though because slight breast asymmetry is common. My doctor called a few months later with my pathology results and there was a PASH in one boob and Ductal Hyperplasia in the other which is abnormal because I’m only 19. Now the boobs are very noticably different and I’m concerned, does the pathology have to do with it? I am 5’ 7” and 120
