Cosmetic surgery is performed to reshape normal structures of the body in order to improve the patient’s appearance. Cosmetic surgery is usually not covered by health insurance because it is elective. Reconstructive surgery is administered on abnormal structures of the body caused by congenital defects, developmental abnormalities, trauma, infection, tumors, or disease. It is performed to improve function but may also be done to approximate a normal appearance. Reconstructive surgery is generally covered by most health insurance policies, although coverage for specific procedures and levels of coverage may vary greatly.
