725.310—Modification of awards and denials.

(a) Upon his or her own initiative, or upon the request of any party on grounds of a change in conditions or because of a mistake in a determination of fact, the district director may, at any time before one year from the date of the last payment of benefits, or at any time before one year after the denial of a claim, reconsider the terms of an award or denial of benefits.
(b) Modification proceedings shall be conducted in accordance with the provisions of this part as appropriate, except that the claimant and the operator, or group of operators or the fund, as appropriate, shall each be entitled to submit no more than one additional chest X-ray interpretation, one additional pulmonary function test, one additional arterial blood gas study, and one additional medical report in support of its affirmative case along with such rebuttal evidence and additional statements as are authorized by paragraphs (a)(2)(ii) and (a)(3)(ii) of § 725.414. Modification proceedings shall not be initiated before an administrative law judge or the Benefits Review Board.
(c) At the conclusion of modification proceedings before the district director, the district director may issue a proposed decision and order ( § 725.418) or, if appropriate, deny the claim by reason of abandonment ( § 725.409 ). In any case in which the district director has initiated modification proceedings on his own initiative to alter the terms of an award or denial of benefits issued by an administrative law judge, the district director shall, at the conclusion of modification proceedings, forward the claim for a hearing ( § 725.421 ). In any case forwarded for a hearing, the administrative law judge assigned to hear such case shall consider whether any additional evidence submitted by the parties demonstrates a change in condition and, regardless of whether the parties have submitted new evidence, whether the evidence of record demonstrates a mistake in a determination of fact.
(d) An order issued following the conclusion of modification proceedings may terminate, continue, reinstate, increase or decrease benefit payments or award benefits. Such order shall not affect any benefits previously paid, except that an order increasing the amount of benefits payable based on a finding of a mistake in a determination of fact may be made effective on the date from which benefits were determined payable by the terms of an earlier award. In the case of an award which is decreased, no payment made in excess of the decreased rate prior to the date upon which the party requested reconsideration under paragraph (a) of this section shall be subject to collection or offset under subpart H of this part, provided the claimant is without fault as defined by § 725.543. In the case of an award which is decreased following the initiation of modification by the district director, no payment made in excess of the decreased rate prior to the date upon which the district director initiated modification proceedings under paragraph (a) shall be subject to collection or offset under subpart H of this part, provided the claimant is without fault as defined by § 725.543. In the case of an award which has become final and is thereafter terminated, no payment made prior to the date upon which the party requested reconsideration under paragraph (a) shall be subject to collection or offset under subpart H of this part. In the case of an award which has become final and is thereafter terminated following the initiation of modification by the district director, no payment made prior to the date upon which the district director initiated modification proceedings under paragraph (a) shall be subject to collection or offset under subpart H of this part.
