55 Pa. Code § 3170.82
Residential services may be purchased or paid for only for those children whose custody is vested with the county agency, or who are receiving shelter care or juvenile detention services or who have been committed by the court to a facility for delinquents. Nonresidential services shall be purchased for children for whom the public agency has accepted responsibility, for children referred by the court under informal adjustment, and for children being diverted from the system by agencies exclusively operated for this purpose. The Department will reimburse the county for the cost of purchasing generic children and youth social services to a child regardless of income, including dependent, delinquent, mentally and physically disabled children, and drug and alcohol abusers.
