Apportionment is based on which of the following factors?

• A. Medical Report
• B. Causation
• C. Preexisting condition
• D. Pathology

Answer: (B)

Apportionment is about dividing disability among the different causes that contributed to it. The factor used to decide how much of the impairment is due to the work event is causation—what portion of the illness or injury is caused by the employment, versus a preexisting condition or another factor, or the combination of these. Medical reports help establish that causation and quantify how much each cause contributed. For example, if a worker has a preexisting spine condition and a work-related fall that worsens symptoms, the disability is apportioned according to how much of the impairment is caused by the work event versus the preexisting condition. Preexisting conditions and pathology influence the apportionment only through their effect on causation, not as the primary basis itself.
