For purposes of this section, the term “supplemental security income benefits” means benefits paid or payable by the Commissioner of Social Security under subchapter XVI, including State supplementary payments under an agreement pursuant to section 1382e(a) of this title or an administration agreement under section 212(b) of Public Law 93–66.
From the amount of the reduction made under subsection (a), the Commissioner of Social Security shall reimburse the State on behalf of which supplementary payments were made for the amount (if any) by which such State’s expenditures on account of such supplementary payments for the month or months involved exceeded the expenditures which the State would have made (for such month or months) if the individual had received the benefits under subchapter II at the times they were regularly due. An amount equal to the portion of such reduction remaining after reimbursement of the State under the preceding sentence shall be covered into the general fund of the Treasury.
