This is a surgery to make the umbilicus (belly button) look nicer. It’s often performed to turn an “outie” into an “innie.” A small incision is made at the base of the umbilicus, any fat protruding through the base of the belly button is pushed back inwards (creating the innie), and the small hole is sutured closed. Excess skin may or may not be excised as well.
In most cases this surgery is essentially an umbilical hernia repair. So it’s important for you to know that if you do consider an umbilicoplasty to make your outie into an innie, your health insurance may cover the procedure. So prior to signing on the dotted line and paying for a cosmetic procedure, ask your plastic surgeon if your health insurance might cover it. You may be able to save a lot of money!
