Key Takeaways

Get medical care first—serious injuries may require emergency response immediately.
Employers must provide the DWC-1 claim form within one working day of learning of an injury.
The employee files the claim with the carrier; the carrier decides acceptance within statutory deadlines.
Prompt reporting and early communication reduce disputed claims and litigation.
Return-to-work programs shorten claim duration and protect the experience mod.

Step 1: Get Medical Care

For serious injuries, call 911 or direct the employee to emergency care immediately. For minor injuries, provide or authorize first aid and document what was given. California requires employers to authorize medical treatment, and delaying care can worsen outcomes and complicate the claim.

Step 2: Provide the DWC-1 Claim Form

Within one working day of learning of an injury, the employer must give the employee the DWC-1 workers' compensation claim form with instructions. Even if the injury seems minor, providing the form on time is a legal obligation—the employee decides whether to file it.

Step 3: Report to Your Carrier

Send the completed claim form to your insurance carrier promptly—within five working days under the standard rule. The carrier is responsible for investigating and accepting or denying the claim within statutory deadlines. Keep a copy of everything you submit.

Step 4: What the Employee Can Expect

If the claim is accepted, the employee receives medical treatment for the injury, plus wage-replacement (temporary disability) benefits if authorized off work. Impairment and permanent disability benefits may follow for serious injuries. If denied, the employee can challenge the decision through the Division of Workers' Compensation.

Step 5: Focus on Return to Work

Modified or transitional duty helps injured employees stay connected to work and recover faster, and it reduces the total cost of the claim. Because claim cost drives your experience mod, a strong return-to-work program is one of the best premium protections you have.
