Is butt augmentation covered by insurance?

No this is not a procedure that is typically covered by insurance. Generally, the insurance covers only procedures that are considered functional and it would be extremely unusual that a buttock augmentation will provide improved function.

Insurance won't pay for needed care - this is elective cosmetic surgery - you want it, you pay for it.  Insurance companies do not believe that a small butt is a disease.

In an era where inssurance companies deny breast cancer reconstruction in some cases, it is very unlikely they will cover buttock augmentation for cosmetic reasons. It is always form versus function. Best of luck!
