Your medical insurance may cover a portion or all of the cost of eyelid surgery if the procedure is deemed medical necessary. Eyelid surgery is considered to be medically necessary if it is performed to remove excess upper eyelid skin and fat that hangs below the lash line and interferes with the line of sight. Before covering the cost of upper eyelid surgery, insurance companies require proof of a visual test conducted by an eye doctor. Lower eyelid surgery is not covered by insurance.
