In the case of a surviving parent, brother, or sister, whose claim
was filed at any time, or of a miner whose claim was filed on or after
January 1, 1982, benefit payments are reduced as appropriate by an
amount equal to the deduction which would be made with respect to
excess earnings under the provisions of sections 203 (b), (f), (g),
(h), (j), and (l) of the Social Security Act (42 U.S.C. 403 (b), (f),
(g), (h), (j), and (l)), as if such benefit payments were benefits
payable under section 202 of the Social Security Act (42 U.S.C. 402)
(see Secs. 404.428 through 404.456 of this title).
