Summary of California’s Workers’ Compensation Landscape
California operates a mandatory no-fault workers’ compensation system covering medical care, temporary disability, permanent disability, and supplemental job displacement benefits.
- Reporting Deadline: Employees must report injuries to employers within 30 days of the injury (or when they became aware it was work-related).
- Authorized Medical Care: Controlled initially by the employer’s Medical Provider Network (MPN) if one is established, unless the employee pre-designated their personal physician prior to the injury.
- Wage Replacement: Temporary Disability (TD) benefits provide two-thirds of the injured worker’s average weekly wage (subject to state-mandated minimum and maximum caps).
- Key Deadlines & Limits:
- 30 Days: To report the injury to the employer.
- 104 Weeks: Maximum limit for temporary disability payments within a 5-year window from the date of injury for most conditions.
- 1 Year: Statute of limitations to file an official Application for Adjudication of Claim with the WCAB if benefits are denied.
