S.C. Code Ann. § 38-71-130: Breast reconstruction and prosthetic devices; coverage following mastectomy surgery.

All individual and group health insurance policies and health maintenance organizations providing coverage for mastectomy surgery must provide coverage for prosthetic devices and reconstruction of the breast on which surgery for breast cancer has been performed and surgery and reconstruction of the non-diseased breast, if determined medically necessary by the patient's attending physician with the approval of the insurer or HMO. The provisions of this section shall not require supplemental health insurance policies to provide coverage for reconstruction of the nondiseased breast.
