20 CFR 30.806: What kind of medical evidence must the claimant submit to prove that he or she lost wages due to a covered illness?

OWCP requires the submission of rationalized medical evidence of sufficient probative value to convince the fact-finder that the covered Part E employee experienced a loss in wages in his or her trigger month due to a covered illness, i.e., medical evidence based on a physician's fully explained and reasoned decision (see § 30.805(a)(3)). A loss in wages in the trigger month due solely to non-covered illness matters, such as a reduction in force or voluntary retirement, is not proof of compensable wage-loss under Part E.
