S.D. Codified Laws § 58-38-22
Each service or indemnity-type contract issued by a nonprofit medical and surgical service plan corporation that covers a female and that is delivered, issued for delivery, or renewed in this state, except for a contract that provides coverage for specified disease or other limited benefit coverage, shall provide coverage for screening by low-dose mammography for the presence of occult breast cancer that is subject to the same dollar limits, deductibles and coinsurance factors as for other radiological examinations. Coverage for the screening shall be provided as follows: ages thirty-five to thirty-nine, one baseline mammography; ages forty to forty-nine, a mammography every other year; and age fifty and older, a mammography every year.
As used in this section, "low-dose mammography" means the X ray examination of the breast using equipment dedicated specifically for mammography, including the X ray tube, filter, compression device, screens, films, and cassettes, with an average radiation exposure delivery of less than one rad midbreast, with two views for each breast and with interpretation by a qualified radiologist.
The provisions of this section apply only to grandfathered plans pursuant to 75 Fed. Reg. 116 (2010) to be codified at 26 C.F.R. §§ 54 and 602, 29 C.F.R. § 2590, and 45 C.F.R. § 147.
