Is it possible to get insurance to help pay for thighs to be reshaped or fat reduction in that area? Not cosmetic.

I'm a big girl who's weight has always fluctuated. I eat healthy and have been boxing for years. No matter how small I get or how low I get my BMI, my weight distribution in my inner thighs is horrible and painful.obviously a reduction in thigh size is nice, but I really feel I need something done because I spend a great deal of time in pain due to severe chafing and skin irritation. Bottom line is I need surgical intervention but was wondering how to get financial help from insurance.
