What Is Labor Code Section 4600?
California Labor Code Section 4600 defines the statutory framework for workers' compensation benefits when an employee suffers a work‑related injury or illness. It sets out the types of compensation available, the calculation methods for temporary disability (TD) and permanent disability (PD), and the procedural rights of both workers and employers.

Key Definitions and Scope
Section 4600 applies to:
- All non‑exempt employees covered by California's workers' compensation system.
- Injuries or occupational diseases arising out of and in the course of employment.
- Both medical treatment benefits and wage‑replacement benefits.
Important terms:
- Temporary Disability (TD): Wage replacement for the period an employee cannot work due to a work‑related injury.
- Permanent Disability (PD): Compensation for lasting impairment after the injury has healed.
- Maximum Temporary Disability (MTD): The highest weekly benefit an injured worker can receive, set by law.
Eligibility Requirements
To qualify for benefits under Section 4600, a worker must:
- File a claim within one year of the injury or discovery of the disease.
- Provide medical evidence linking the condition to employment.
- Cooperate with the employer's workers' compensation insurance carrier during the investigation.
How Benefits Are Calculated
The statute outlines a formula for TD benefits based on the worker's average weekly wage (AWW):
| Metric | Estimate or Range | Context |
|---|---|---|
| Average Weekly Wage (AWW) | Sum of wages over 13 weeks ÷ 13 | Used as the base for TD calculations. |
| Temporary Disability Rate | 2/3 of AWW | Maximum weekly TD benefit before caps. |
| Maximum Temporary Disability (MTD) Cap | $1,539 (2024) | State‑set weekly limit; adjusted annually. |
If the 2/3 AWW exceeds the MTD cap, the worker receives the capped amount. Permanent disability benefits are calculated using a separate schedule that assigns a monetary value to each type of impairment.
Employer Obligations Under Section 4600
Employers must:
- Maintain workers' compensation insurance or qualify as a self‑insured carrier.
- Provide the injured employee with a claim form (DWC‑1) within one day of the injury.
- Report the injury to the insurer within five days of receiving the claim.
- Cooperate with medical providers and the claims adjuster throughout the process.
Common Misconceptions
Many employees assume that workers' compensation only covers medical bills. Section 4600 explicitly provides wage‑replacement benefits, making it a crucial safety net for lost earnings. Another myth is that filing a claim will automatically lead to termination; California law protects workers from retaliation for filing a legitimate claim.
Steps to Take After a Workplace Injury
Follow this checklist to protect your rights under Section 4600:
- Seek immediate medical attention and keep all records.
- Notify your employer in writing as soon as possible.
- Complete and return the DWC‑1 claim form.
- Track all communications with your employer and insurance carrier.
- Consider consulting a workers' compensation attorney if benefits are denied or delayed.
Appeals and Dispute Resolution
If a claim is denied, the worker can request a hearing before the California Workers' Compensation Appeals Board (WCAB). Section 4600 provides the legal basis for these appeals, ensuring that the dispute is reviewed based on statutory criteria rather than employer discretion.
