Acceptance under former Part D


Claimant’s responsibilities


Consequential conditions

  • An injury, illness, impairment or disability sustained as a consequence of a covered beryllium illness must be established with a fully rationalized medical report by a physician that shows causal relationship. Neither the fact that the injury, illness, impairment or disability manifests itself after a diagnosis of a covered beryllium illness, nor the belief by the claimant that the injury, illness, impairment or disability was caused by the covered beryllium illness, is sufficient in itself to prove a causal relationship. EEOICPA Fin. Dec. No. 19516-2004 (Dep’t of Labor, October 15, 2004).
  • Employee satisfied his burden to prove that his coronary artery disease was a consequence of radiation treatment for his lung cancer. EEOICPA Fin. Dec. No. 10032182-2006 (Dep’t of Labor, March 3, 2008).


Covered employment


Exposure

  • As part of its adjudication process, OWCP may perform a search through the Department of Labor’s Site Exposure Matrices (SEM) to ascertain whether a particular labor category could potentially have been exposed to toxic substances. The SEM contains a list of processes performed by different labor categories including uranium recovery, purification and recycle operations. EEOICPA Fin. Dec. No. 20858-2006 (Dep’t of Labor, June 30, 2006).
  • In the absence of substantial evidence to the contrary, a covered beryllium employee under Part B shall be presumed to have been exposed to beryllium in the performance of duty if the employee: (1) was employed at a DOE facility; or (2) was present at a DOE facility; or (3) was present at a facility owned and operated by a beryllium vendor because of employment by either the United States, a beryllium vendor, or a contractor or subcontractor of the DOE during a period when beryllium dust, particles, or vapor may have been present at such a facility. EEOICPA Fin. Dec. No. 60165-2005 (Dep’t of Labor, May 10, 2005).


Medical evidence of covered illness under Part E

  • An employee may satisfy his burden to prove causation under Part E even in a case where his Part B claim for the same illness underwent a dose reconstruction and the resulting determination of the probability of causation was less than 50%. A SEM search identified several toxic substances to which the employee may have been exposed and a DMC opined that such occupational exposure was at least as likely as not a significant factor in aggravating, contributing to or causing the employee’s non-Hodgkin’s lymphoma. Therefore, FAB denied his Part B claim because the probability of causation was less than 50%, while it accepted his Part E claim for the same illness. EEOICPA Fin. Dec. No. 81625-2008 (Dep’t of Labor, July 30, 2008).
  • Where district medical consultant and employee’s attending physician disagreed on whether radiation therapy for employee’s lung cancer contributed to his heart disease, which led to congestive heart failure and death, the weight of the medical evidence was found to be represented by opinion of attending physician that was based on numerous physical examinations of employee, in combination with a well-rationalized, probative opinion supporting causal relationship submitted by a specialist. EEOICPA Fin. Dec. No. 10006745-2006 (Dep’t of Labor, July 27, 2006).
  • In the case where an employee is not entitled to a presumption of causation under subsection (a) or (b) of § 7385s-4, the evidence must establish that it is at least as likely as not that exposure to a toxic substance at a DOE facility was a significant factor in aggravating, contributing to, or causing the employee’s illness and that it is at least as likely as not that the employee’s exposure to a toxic substance was related to his work at the DOE facility. EEOICPA Fin. Dec. No. 10016501-2007 (Dep’t of Labor, May 7, 2007).
  • The FAB denied claim of survivors for employee’s possible CBD and breathing problems under Parts B and E of the Act. Under Part E, CBD may be established with a physician’s diagnosis and a review of the medical evidence as a whole. The statutory requirements that define CBD under Part B do not apply to the evaluation of CBD claims under Part E. In this case, the medical evidence was insufficient to establish that the employee was diagnosed with the claimed conditions of CBD and breathing problems. EEOICPA Fin. Dec. No. 10027260-2006 (Dep’t of Labor, December 6, 2006).
  • Where the DMC found that abdominal aortic aneurisms are not known to be caused, contributed to, or aggravated by exposure to toxic substances, but the medical notes stated that the employee’s aneurism was not able to be surgically corrected because of the employee’s significant medical problems (including his covered illness), the DMC concluded that it was at least as likely as not that that covered illness was a significant factor in aggravating the employee’s aneurism. FAB agreed that the element of “aggravating” in the Part E causation standard was satisfied and awarded the employee medical benefits for his abdominal aortic aneurism. EEOICPA Fin. Dec. No. 10076658-2009 (Dep’t of Labor, October 29, 2008).
  • Where the DMC found that the employee’s covered illness was a significant factor in contributing to the employee’s congestive heart failure, FAB concluded that the element of “contributing to” in the Part E causation standard was satisfied and awarded him medical benefits for his congestive heart failure. EEOICPA Fin. Dec. No. 10076658-2009 (Dep’t of Labor, October 29, 2008).
