(a) Every private duty nursing agency for which a license has been issued, except a facility that is certified to participate either in the Medicare program under Title XVIII (42 U.S.C. Sec. 1395 et seq.) of the federal Social Security Act, or the medicaid program under Title XIX (42 U.S.C. Sec. 1396 et seq.) of the federal Social Security Act, or both, shall be periodically inspected by a duly authorized representative of the department.
