Will the military pay for my BBL

I would not know the answer to that, but that sounds counter to what the federal government would do.

As a rule, insurance doesn't cover cosmetic procedures.  Insurance will cover some things that are considered cosmetic when their is a medical reason a person needs it.  For example, a breast implant in someone that has had breast cancer or a upper eyelid reduction for someone that has failed their field of vision exam.  But a procedure that isn't a medical necessity, i.e. is cosmetic, than they will not cover it.  You're always welcome to work with your in network plastic surgeon's office to try to submit your claim to see what they say.  
Personally I don't take insurance because of the red tape and time constraints.  I wish you the best in your pursuit.  If insurance doesn't work, don't give up.  There are many financing companies that work with all types of credit and offer co-signers.  

Hello justice96 - The Brazilian Butt Lift is a procedure designed to transfer fat from one area of the body, typically the stomach and thighs, hips, knees, and back to the buttock through liposuction. The procedure is meant to reshape, but also enhances the size of a buttock to better fit the figure and provides a perky appearance to rear end. It is unique by the use of the patients own harvested body fat, rather than the use of synthetic material. This allows for a healthier and longer lasting result. Typically insurance does not pay for cosmetic procedures. Next step for you is to schedule a consultation with a board certified plastic surgeon to discuss your options and goals. Best wishes and thank you for you service.
