Greater Los Angeles Workers' Compensation Filing Calendar: Milestones and Deadlines
A chronological milestone calendar tracking essential statutory notice, medical network selection, evaluation, and hearing deadlines for injured workers in Greater Los Angeles.
Filing a workers' compensation claim in the Greater Los Angeles area requires navigating strict legal deadlines across multiple administrative venues. The Workers' Compensation Appeals Board (WCAB) operates several district offices across Los Angeles County—including Los Angeles (Downtown), Van Nuys, Long Beach, Marina del Rey, and Pomona. Each step in the claims process, from initial injury notification to formal hearing, is governed by statutory time frames set forth in the California Labor Code.
Missing a mandatory reporting deadline or mismanaging medical panel timelines can result in denied benefits, delayed medical treatment, or loss of legal rights. This action calendar organizes what you must do and by when, structured chronologically from Day 1 through Month 12. Each milestone entry is intentionally brief; the pages linked at each step provide the procedural depth.
Milestone 1 — What You Must Do Immediately: Days 1 to 30
Day 1: Report the injury to your employer in writing. Under Labor Code Section 5400, written notice of injury must be given to the employer within 30 days of the incident, or within 30 days of first recognizing that an illness or cumulative trauma is work-related. Waiting beyond 30 days without good cause can jeopardize your claim.
Within 1 working day of your report: Obtain the DWC-1 claim form from your employer. Under Labor Code Section 5401, the employer must provide the DWC-1 form within one working day of receiving notice or knowledge of the injury. Complete and return the form promptly. For step-by-step form completion guidance, see filing packet faq.
Days 1–30: Receive authorized initial medical care. Under Labor Code Section 5401, while the claim is under investigation the employer's insurer must authorize up to $10,000 in medical treatment consistent with the applicable medical treatment utilization schedule. This authorization is not an admission of liability.
Milestone 2 — Watch the 90-Day Window: Days 31 to 90
Day 90: The compensability presumption deadline. Under Labor Code Section 5402, if the insurer does not reject liability within 90 days after receiving your completed and signed DWC-1 form, the injury is presumed compensable. The insurer may rebut this presumption only with evidence discovered after the 90-day period closes. Track the date you returned the signed DWC-1 form; that date starts the clock.
Ongoing: Monitor temporary disability payment timing. If the claim is accepted or benefits are authorized during the investigation window, temporary disability indemnity payments must begin within 14 days of the insurer's knowledge of the injury and disability, and must be paid every 14 days thereafter. For a broader explanation of how the claim moves through the system after acceptance, see claim lifecycle.
Milestone 3 — Medical Disputes and QME Panels: Months 3 to 6
Month 3: Choose your treating physician within the Medical Provider Network (MPN). If your employer maintains an approved MPN, you must select a treating physician from the network directory after initial emergency treatment or the first treatment visit. Treating outside the MPN without authorization can affect your right to reimbursement.
Months 4–5: Request a QME panel if a medical dispute arises. When either party disputes a medical determination by the primary treating physician—on compensability, permanent disability, or treatment necessity—a Panel Qualified Medical Evaluator (QME) must be requested through the DWC Medical Unit. Strict statutory timelines govern panel requests, specialty selection, and doctor-strike procedures. For procedural motions involving panel disputes and replacement-QME requests, see replacement qme motion record.
Month 6: Attend the QME examination. The QME evaluation must be scheduled within statutory windows after the panel issues. Medical records must be served to the evaluator before the appointment. Missing or rescheduling without good cause can waive your right to that evaluator.
Milestone 4 — Opening a Formal WCAB File: Months 6 to 9
File your Application for Adjudication of Claim. Under Labor Code Section 5501, an injured worker or their attorney files an Application for Adjudication of Claim with the appropriate WCAB district office to establish formal jurisdiction over the dispute.
Select the correct Los Angeles venue. Venue is determined by the injured worker's residence at the time of injury, the place where the injury occurred, or the employer's principal place of business. Greater Los Angeles WCAB district offices include Downtown Los Angeles, Van Nuys, Long Beach, Marina del Rey, and Pomona. Filing at the wrong venue can cause delays; confirm the correct office before filing.
Milestone 5 — Settlement Conference and Trial: Months 9 to 12
File a Declaration of Readiness to Proceed (DOR). Once medical evidence is complete and the dispute is ripe for resolution, a party files a DOR to request a Mandatory Settlement Conference (MSC). Do not file a DOR before medical evidence is complete; premature filing can result in a continuance and delay your hearing date.
Months 10–11: Attend the Mandatory Settlement Conference. Under Labor Code Section 5502, an MSC must be held within a statutory window after the DOR is filed. At the MSC, the parties attempt to settle and, if the case does not resolve, prepare a Joint Pre-Trial Conference Statement listing all witnesses and exhibits. For what to bring and how to prepare your exhibit list, see trial preparation protocol.
Month 12: Trial before a Workers' Compensation Administrative Law Judge (WCALJ). If the matter does not settle at the MSC, a trial is scheduled pursuant to the hearing timeframes in Labor Code Section 5502. The WCALJ issues a written decision after the trial record closes.
