20 C.F.R. § 10.714
The refundable disbursements of a specific claim consist of the total money paid by OWCP from the Employees' Compensation Fund with respect to that claim to or on behalf of a FECA beneficiary including charges for field nurses, vocational rehabilitation, and second opinion and referee physicians, less charges for any medical file review ( i.e., the physician does not examine the employee) done at the request of OWCP. Charges for medical examinations also may be subtracted if the FECA beneficiary establishes that the examinations were required to be made available to the employee under a statute other than the FECA by the employing agency or at the employing agency's cost. Requests for disbursements can be made to SOL or OWCP.
