42 USC 1704 - Reimbursement
Where any employer or his insurance carrier or compensation fund pays or is required to pay benefits
such employer, carrier, or fund shall be entitled to be reimbursed for all benefits so paid or payable, including funeral and burial expenses, medical, hospital, or other similar costs for treatment and care; and reasonable and necessary claims expense in connection therewith. Claim for such reimbursement shall be filed with the Secretary under regulations promulgated by him, and such claims, or such part thereof as may be allowed by the Secretary, shall be paid from the compensation fund established under section 8147 of title 5. The Secretary may, under such regulations as he shall prescribe, pay such benefits, as they accrue and in lieu of reimbursement, directly to any person entitled thereto, and the insolvency of such employer, insurance carrier, or compensation fund shall not affect the right of the beneficiaries of such benefits to receive the compensation directly from the said compensation fund established under section 8147 of title 5. The Secretary may also, under such regulations as he shall prescribe, use any private facilities, or such Government facilities as may be available, for the treatment or care of any person entitled thereto.
No reimbursement shall be made under this subchapter in any case in which the Secretary finds that the benefits paid or payable were on account of injury, detention, or death which arose from a war-risk hazard for which a premium (which included an additional charge or loading for such hazard) was charged.
The provisions of this section shall not apply with respect to benefits on account of any injury or death occurring within any State.
