Adds a new paragraph (6) to subsection (c) creating a rebuttable presumption that a deceased miner's death was due to pneumoconiosis if the miner was totally disabled due to pneumoconiosis during life and does not meet the irrebuttable presumption under paragraph (3); the presumption may be rebutted only by establishing that no part of the death was caused by pneumoconiosis.

Modifies the second sentence of paragraph (2) (as shown in the statute) and replaces the term 'respirable' with 'respiratory' within the paragraph.

Alters the findings and declaration of purpose language to account for miners who 'were totally disabled by this disease at the time of their deaths' by striking and inserting specified text.

Strikes specified language in subsection (a) of section 411 (30 U.S.C. 921(a)) as described in the amendment (text indicated in the bill).

Adds a new section (titled '403 Attorneys’ fees and medical expenses payment program') to Part A of the Black Lung Benefits Act establishing a payment program to pay attorneys’ fees and unreimbursed medical expenses from the fund for qualifying claims, specifying program rules, payment caps, reimbursement by liable operators, and nonrecoupment from claimants or their attorneys.
