S.C. Code Ann. § 44-20-250

The Office of Intellectual and Developmental Disabilities shall coordinate services and programs with other state and local agencies for persons with intellectual disability, related disabilities, head injuries, and spinal cord injuries. The Department of Behavioral Health and Developmental Disabilities may negotiate and contract with local agencies, county boards of disabilities and special needs, private organizations, and foundations in order to implement the planning and development of a full range of services and programs for persons with intellectual disability, related disabilities, head injuries, and spinal cord injuries subject to law and the availability of fiscal resources. The office has the same right to be reimbursed for expenses in providing disabilities and special needs services through a contractual arrangement as it has to be reimbursed for expenses provided through direct office services. The department shall develop service standards for programs of the office and for programs for which the office may contract and shall review and evaluate these programs on a periodic basis.
