Which of the following questions is relevant for determining a compensable combined condition?

Determining a compensable combined condition involves assessing whether a preexisting condition contributes to the current claim for benefits. A qualified preexisting condition is essential because it helps in understanding how much of the current issue might be related to earlier injuries or health issues. If a worker has a valid preexisting condition, it may indicate that the recent work-related injury might not solely be the cause of their current symptoms, thus influencing the eligibility for workers' compensation.

The relevance of the other questions, while important in their own contexts, does not directly contribute to the assessment of combined conditions. Knowing about workplace injuries may provide context but does not clarify the status of preexisting conditions. Timely reporting of injuries is crucial for the claims process, but it does not address the relationship of preexisting health issues to current symptoms. Employment status, whether full-time or part-time, relates more to eligibility for benefits rather than the specifics of the condition itself. Therefore, identifying a qualified preexisting condition is central to determining whether the claim is compensable under combined conditions.
