Enforcement of right; waiver.

(a) In enforcing its right to reimbursement, the District may:

(1) Permit the beneficiary to proceed on behalf of the District in prosecuting, in conjunction with his or her own claims, the District’s claim for the unreimbursed value or cost of the health-care assistance provided;

(2) Intervene or join in any proceeding brought by the beneficiary;

(3) Institute and prosecute a proceeding either alone (in its own or the beneficiary’s name) or in conjunction with the beneficiary; or

(4) Compromise or settle and execute a release of its claim against a third party.

(b) The Mayor may waive, in whole or in part, enforcement of the District’s claim against a third party if enforcement in a particular case would not be cost effective or would result in undue hardship to the beneficiary, including any dependents or survivors of the actual recipient of health-care assistance. If waiver is based on the avoidance of undue hardship, the Mayor may in addition void the legal subrogation or assignment effected pursuant to § 4-602(b) . In determining whether, and to what extent, reimbursement should be sought or awarded under this chapter, the Mayor or a court, respectively, shall give due consideration to the extent of the beneficiary’s injuries and his or her current and future needs, including the current and future needs of any dependents or survivors of the actual recipient of health-care assistance.
