California Workers' Compensation Form

What the California Workers' Compensation Form Is

The California Workers' Compensation Form (commonly referred to by employers and claims administrators as the DWC-1 or employee claim form) is the standard document used to report a workplace injury or illness and to start a workers' compensation claim. It captures essential facts about the worker, employer, date and location of the injury, a short description of how the injury occurred, and initial medical treatment information. Completing the form promptly establishes an official record that insurers and claims examiners use to evaluate benefits eligibility, medical care authorization, and wage replacement.

Why this Form Matters for Claims and Compliance

A correctly completed California Workers' Compensation Form creates the formal claim record, documents the injury timeline, and triggers benefit evaluation and medical authorization. Timely and accurate completion helps avoid delays in treatment, protects wage replacement entitlements, and reduces disputes about what happened and when.

  • Employer or HR — Completes employer sections, records job details, and forwards the form to the insurer.
  • Claims examiner / medical provider — Reviews the form to authorize treatment, assign a claim number, and coordinate benefits.

Common preparation errors to avoid

  • Leaving the date or time of injury blank, which makes it difficult to establish when the work-related event occurred and invites follow-up requests.
  • Providing vague injury descriptions such as 'hurt at work' instead of detailing the sequence of events and the body part involved, causing delays in medical authorization.
  • Failing to include the treating provider's name and initial treatment date, which can slow approval for follow-up care and diagnostic services.
  • Not retaining a signed copy for the worker and employer, which complicates evidence gathering if coverage disputes arise later.

How the form moves through the claims process

A typical routing sequence shows who receives the form and what each party does next.

  • Employer Review: Employer verifies details and forwards to insurer or claims administrator.
  • Insurer Intake: Insurer opens claim file and assigns a claim number.
  • Medical Authorization: Claims examiner authorizes initial treatment and referrals.
  • Benefits Processing: Wage replacement and medical billing are coordinated and paid.

Insurer Acknowledgement:
