Defines "treatment" to include reconstructive surgical procedures that are performed on abnormal structures of the body caused by congenital defects, abnormalities, trauma, infection, tumors, or disease, including: (1) procedures that do not materially affect the function of the body part being treated; and (2) procedures for secondary conditions and follow-up treatment.
