Which entity determines compensability in California workers' compensation disputes?

• A. WCAB
• B. Employer
• C. Employee
• D. TPA

Answer: (A)

Compensability is decided by the Workers’ Compensation Appeals Board. The WCAB is the adjudicatory body that interprets the Labor Code and resolves disputes about whether an injury or illness is within the California workers’ compensation system and what benefits are due. While an employer or their claims administrator can investigate, accept or deny a claim, and manage benefits, the legal determination of compensability rests with the WCAB, based on evidence presented (often starting with a Workers’ Compensation Judge and, if appealed, reviewed by the Board). A third-party administrator handles administrative tasks but does not determine compensability.
