Section 30.901 - How does OWCP determine the extent of an employee's impairment that is due to a covered illness contracted through exposure to a toxic substance at a DOE facility or a RECA section 5 facility, as appropriate?(a) OWCP will determine the amount of impairment benefits to which an employee is entitled based on one or more impairment evaluations submitted by physicians. An impairment evaluation shall contain the physician's opinion on the extent of whole person impairment of all organs and body functions of the employee that are compromised or otherwise affected by the employee's covered illness or illnesses, which shall be referred to as an "impairment rating."(b) In making impairment benefit determinations, OWCP will only consider medical reports from physicians who are certified by the relevant medical board and who satisfy any additional criteria determined by OWCP to be necessary to qualify to perform impairment evaluations under Part E, including any specific training and experience related to particular conditions and other objective factors.(c) OWCP will establish criteria based upon objective factors such as training and certification that must be met by physicians preparing impairment evaluations in order for an impairment evaluation to be considered in determining an impairment award. Such criteria shall be made available to claimants and the public by OWCP. 71 FR 78534 , Dec. 29, 2006, as amended at 84 FR 3060 , Feb. 8, 2019
