To provide viable options for an array of community-based services for individuals with developmental disabilities, the Department of Human Services, subject to state and federal funding restrictions, shall establish a reimbursement rate structure for contracting with community programs licensed by the Board of Developmental Disabilities Services that will cover costs of all federal and state mandates for which they are held responsible by the department and for any additionally required processes the department may elect to implement for cost containment and management purposes over and above the established reimbursement rates for costs of treatment services.
