In the case of a claim by a child this paragraph shall apply, notwithstanding any other provision of this part.

(1) No claim for benefits under this part on account of total disability of a miner shall be considered unless it is filed on or before December 31, 1973, or, in the case of a claimant who is a widow, within six months after the death of her husband or by December 31, 1973, whichever is the later.

In the case of a claim by a child this paragraph shall apply, notwithstanding any other provision of this part.

(A) If such claim is filed within six months following May 1972, and if entitlement to benefits is established pursuant to such claim, such entitlement shall be effective retroactively from December 30, 1969, or from the date such child would have been first eligible for such benefit payments had section 922(a)(3) of this title been applicable since December 30, 1969, whichever is the lesser period. If on the date such claim is filed the claimant is not eligible for benefit payments, but was eligible at any period of time during the period from December 30, 1969, to the date such claim is filed, entitlement shall be effective for the duration of eligibility during such period.

(B) If such claim is filed after six months following May 1972, and if entitlement to benefits is established pursuant to such claim, such entitlement shall be effective retroactively from a date twelve months preceding the date such claim is filed, or from the date such child would have been first eligible for such benefit payments had section 922(a)(3) of this title been applicable since December 30, 1969, whichever is the lesser period.

(D) Any benefit under subparagraph (A) or (B) for a month prior to the month in which a claim is filed shall be reduced, to any extent that may be necessary, so that it will not render erroneous any benefit which, before the filing of such claim, the Secretary has certified for payment for such prior month.

No benefits shall be payable to a widow, child, parent, brother, or sister under this part on account of the death of a miner unless (1) benefits under this part were being paid to such miner with respect to disability due to pneumoconiosis prior to his death, (2) the death of such miner occurred prior to January 1, 1974, or (3) any such individual is entitled to benefits under paragraph (5) of section 921(c) of this title.
