42 U.S.C. § 2651

section 249 of this titleIn any case in which the United States is authorized or required by law to furnish or pay for hospital, medical, surgical, or dental care and treatment (including prostheses and medical appliances) to a person who is injured or suffers a disease, after the effective date of this Act, under circumstances creating a tort liability upon some third person (other than or in addition to the United States and except employers of seamen treated under the provisions of ) to pay damages therefor, the United States shall have a right to recover (independent of the rights of the injured or diseased person) from said third person, or that person’s insurer, the reasonable value of the care and treatment so furnished, to be furnished, paid for, or to be paid for and shall, as to this right be subrogated to any right or claim that the injured or diseased person, his guardian, personal representative, estate, dependents, or survivors has against such third person to the extent of the reasonable value of the care and treatment so furnished, to be furnished, paid for, or to be paid for. The head of the department or agency of the United States furnishing such care or treatment may also require the injured or diseased person, his guardian, personal representative, estate, dependents, or survivors, as appropriate, to assign his claim or cause of action against the third person to the extent of that right or claim.

If a member of the uniformed services is injured, or contracts a disease, under circumstances creating a tort liability upon a third person (other than or in addition to the United States and except employers of seamen referred to in subsection (a)) for damages for such injury or disease and the member is unable to perform the member’s regular military duties as a result of the injury or disease, the United States shall have a right (independent of the rights of the member) to recover from the third person or an insurer of the third person, or both, the amount equal to the total amount of the pay that accrues and is to accrue to the member for the period for which the member is unable to perform such duties as a result of the injury or disease and is not assigned to perform other military duties.

The United States may, to enforce a right under subsections (a), (b), and (c) (1) intervene or join in any action or proceeding brought by the injured or diseased person, his guardian, personal representative, estate, dependents, or survivors, against the third person who is liable for the injury or disease or the insurance carrier or other entity responsible for the payment or reimbursement of medical expenses or lost pay; or (2) if such action or proceeding is not commenced within six months after the first day in which care and treatment is furnished or paid for by the United States in connection with the injury or disease involved, institute and prosecute legal proceedings against the third person who is liable for the injury or disease or the insurance carrier or other entity responsible for the payment or reimbursement of medical expenses or lost pay, in a State or Federal court, either alone (in its own name or in the name of the injured person, his guardian, personal representative, estate, dependents, or survivors) or in conjunction with the injured or diseased person, his guardian, personal representative, estate, dependents, or survivors.

The provisions of this section shall not apply with respect to hospital, medical, surgical, or dental care and treatment (including prostheses and medical appliances) furnished by the Department of Veterans Affairs to an eligible veteran for a service-connected disability under the provisions of chapter 17 of title 38.
