The cost of travel, including per diem or subsistence in lieu of per diem, is a proper
charge to the disability program if carried out in accordance with provisions of State
law, regulation, and administrative procedure applicable to travel.
Certain categories of travel may be charged to the disability program without prior
authorization by SSA, provided its purpose is directly related to the disability program,
and the costs are consistent with current funding limitations. Other categories of
travel require prior SSA approval.
For further information regarding DDS travel, refer to DI 39524.001.
