Denied Workers' Comp Claim in California? What to Do Next
California law states that injuries that occur while at work are generally covered by the Workers' Compensation system. This means that injured workers can be entitled to treatment, benefits, and even compensation for the injuries they sustained. The first step to seek benefits under California Workers' Compensation is to file a claim. However, for various reasons, insurance companies can deny claims, and they sometimes deny valid claims. This is where our Pasadena Workers' Compensation lawyer can step in and assist.
After filing a workers' compensation claim in California, the insurer can either accept, delay, or deny that claim. However, a denial letter is not the final word on your claim. In California, you can challenge a denied or delayed workers' compensation claim before the Workers' Compensation Appeals Board (WCAB), and many denials turn on issues that can be disputed with the right arguments. The deadlines are strict, though, so what you do in the next few weeks matters.
This page covers why claims get denied, the difference between a delay and a denial, the process for challenging one, and how to cover your medical care and bills while the dispute is pending.
Denied or delayed? Know which letter you got
California gives the insurer a set timeline, and the letter you received tells you where you are in it.
| What you received | What it means | What happens next |
|---|---|---|
| Acceptance | The insurer agrees the injury is work-related. | Benefits should begin. Disputes can still arise later over treatment or disability. |
| Delay notice | The insurer is still investigating and hasn't decided. | In general, the insurer has up to 90 days from when you filed the claim form to decide. |
| Denial | The insurer disputes that the injury is covered. | You can challenge the denial before the WCAB. |
Two rules work in your favor during this window:
- The 90-day presumption. If the insurer does not deny your claim within 90 days after you file the claim form, an argument can be made that California law presumes the injury is covered. A denial issued after that deadline can be challenged on that basis.
- Medical care during a delay. While the insurer investigates, it generally must authorize up to $10,000 in medical treatment for your injury. A delay does not mean you have to go without care. See how medical care works while your claim is investigated →
Why workers' comp claims get denied
A denial does not necessarily mean you did something wrong. It can sometimes also mean the insurer disputes one specific piece of the claim. Some common reasons claims might be denied:
- “Not work-related.” The insurer says the injury happened off the job or wasn't caused by your work. This is a frequent dispute.
- Late reporting. California generally requires you to tell your employer within 30 days. Late notice gives the insurer an argument, but it is not automatically fatal to a claim. Call a workers' compensation lawyer to see if you need help.
- No witnesses or conflicting accounts. Your employer says the incident didn't happen the way you described it.
- Pre-existing condition. The insurer attributes your condition to an old or prior injury rather than your job.
- Cumulative trauma disputes. For injuries that built up over time, the insurer may argue the condition isn't job-related or that you knew about it too long before filing.
- Post-termination claims. A claim filed after a layoff or firing gets extra scrutiny, and the law sets specific rules for when those claims can proceed.
- Missing paperwork. An incomplete claim form or missing medical records.
Read the denial letter closely. It must state the reason for the denial. That reason tells you what is in dispute and what evidence you may need.
How to challenge a denied claim, step by step
Challenging a denial happens inside the workers' comp court system, run by the WCAB. The usual path:
- 1 Keep the denial letter and every document. Save the letter, your claim form (DWC-1), medical records, pay stubs, and any messages with your employer or the adjuster.
- 2 File an Application for Adjudication of Claim. Injured workers can ask our workers' compensation lawyers to file an application for adjudication of claim.
- 3 Get a medical-legal evaluation. During the dispute, a Qualified Medical Evaluator (or an Agreed Medical Evaluator, if both sides agree) can be brought in to examine the injured worker and assess the injuries.
- 4 File a Declaration of Readiness to Proceed (DOR). This asks the workers' compensation judge to set your case for a hearing.
- 5 Mandatory Settlement Conference (MSC). A workers' comp judge meets with both sides to try to resolve the dispute, which may help in resolving your case.
- 6 Trial. If the case doesn't resolve, a workers' comp judge hears the evidence and issues a written decision.
- 7 Post-trial. If you disagree with the judge's decision, there is an appeal process.
Paying for care and bills while your claim is disputed or delayed
A disputed or delayed claim can take months. Options that may help in the meantime:
- California State Disability Insurance (SDI). If you can't work and your workers' comp claim is denied or delayed, you may be able to apply for SDI.
- Your own health insurance. You may be able to use your personal health plan for treatment during the dispute.
- The $10,000 authorization. During the initial investigation period, the insurer generally must authorize up to $10,000 in treatment.
Denials show up across every local industry. If you work in healthcare, warehouses and delivery, restaurants and offices, retail and grocery, or entertainment and production, the same challenge process applies.
