Notwithstanding any other provision of law, an employee of an agency assigned to a private sector organization under this chapter is entitled to retain coverage, rights, and benefits under subchapter I of chapter 81, and employment during the assignment is deemed employment by the United States, except that, if the employee or the employee’s dependents receive from the private sector organization any payment under an insurance policy for which the premium is wholly paid by the private sector organization, or other benefit of any kind on account of the same injury or death, then, the amount of such payment or benefit shall be credited against any compensation otherwise payable under subchapter I of chapter 81.

The assignment of an employee to a private sector organization under this chapter may be made with or without reimbursement by the private sector organization for the travel and transportation expenses to or from the place of assignment, subject to the same terms and conditions as apply with respect to an employee of a Federal agency or a State or local government under section 3375, and for the pay, or a part thereof, of the employee during assignment. Any reimbursements shall be credited to the appropriation of the agency used for paying the travel and transportation expenses or pay.

The Federal Tort Claims Act and any other Federal tort liability statute apply to an employee of an agency assigned to a private sector organization under this chapter. The supervision of the duties of an employee of an agency so assigned to a private sector organization may be governed by an agreement between the agency and the organization.
