Hello. Depending on what the irregularity is and what the underlying cause is, it may be possible under certain circumstances to have fat grafting covered (i.e. reconstruction after breast cancer). I would suggest seeing a board certified plastic surgeon in your area to see what your options are.
medical insurance does not and will not pay for cosmetic surgery. Unfortunately even restoring someone to a previous contour is not always considered medically indicated. There are of course exceptions like men and women who develop breast cancer. These defects are not only covered by medical insurance but are supported by federal legislation as having to be covered benefits. Defects from previous drama are often caused by contracted is going to shoe which often does not respond well to adding volume transfer. Best, Mats Hagstrom M.D.
