D.C. Mun. Regs. tit. 29, r. 29-600
The District shall furnish transportation, including subsistence en-route and attendents, including volunteer attendants, when needed, to the following categories of non-residents:
Volunteer attendants shall proceed to the point of destination and return as quickly as transportation permits, without stop-off or stop-over for personal reasons.
Arrangements for and conduct of transfers shall be in accordance with standard government travel regulations.
The Department of Human Services shall, upon receipt of proper authorization, transfer to the state of legal residence at District expense those patients in the Psychiatric Department of D. C. General Hospital or Saint Elizabeths Hospital who are found to be on elopement or parole status from state hospitals in other jurisdictions, if the investigation discloses no other practicable source of defraying the cost.
Relatives of patients shall be given written notice of transfer as far in advance of departure as possible. Special attention shall be given to relatives within the Washington D.C. area to allow them time for visiting patient before transfer.
Prior to the transfer of a patient admitted to the hospital through police action, the Department worker assigned responsibility for the trip shall contact the Property Clerk of the Police Department to determine whether he or she is holding any property which ought to be transported with the patient. If property is being held by the Registrar of Saint Elizabeths Hospital, he or she shall be given advance notice of the transfer.
No client shall be transported under compulsion with the exception of non-resident persons who come within the scope of a District law or regulation requiring their confinement.
