Top 7 Reasons Workers’ Compensation Claims Get Denied in California

Denied Claims Are More Common Than You Think

Suffering a workplace injury is stressful enough — but when your workers’ compensation claim gets denied, the situation can feel overwhelming. In California, thousands of employees face denials each year, even when their injuries are legitimate. Insurance companies often use technicalities, deadlines, and loopholes to avoid paying benefits.

The good news? A denial doesn’t mean the end of your case. Understanding the common reasons claims are rejected can help you take the right steps to appeal and secure the benefits you deserve. At Win – Injury & Accident Trial Lawyers, we help injured workers across California fight back against wrongful denials every single day.


1. Failure to Report the Injury on Time

California law requires employees to notify their employer of a workplace injury within 30 days. If you miss this deadline, the insurance company may use it as a reason to deny your claim. Many workers don’t report right away because they hope the pain will go away — but this can backfire. Always document and report your injury as soon as it happens.


2. Claim Not Filed Properly

Filing the DWC-1 claim form is a crucial step. Mistakes, missing signatures, or failing to submit the form correctly can result in denial. Unfortunately, some employers don’t provide the right paperwork or delay the process. Having an attorney ensures all forms are filed correctly and on time.


3. Disputes About Whether the Injury Was Work-Related

One of the most common reasons for denial is when employers or insurers argue that the injury didn’t happen on the job. For example, if you hurt your back but didn’t immediately report it, they may claim it was caused by something outside of work. This is especially common with repetitive stress injuries or conditions that develop over time.


4. Lack of Medical Evidence

Workers’ comp claims depend heavily on medical documentation. If your doctor doesn’t clearly connect your injury to your job, or if you don’t seek medical treatment right away, the insurance company may deny your claim. That’s why it’s essential to see a doctor immediately and ensure all records reflect that the injury is work-related.


5. Pre-Existing Conditions

Insurance companies often argue that your injury was due to a pre-existing condition rather than a workplace accident. For instance, if you had back problems before, they may claim your current injury is unrelated to work. The truth is, even if you had a pre-existing condition, you are still entitled to benefits if work aggravated or worsened it.


6. Missed Deadlines or Paperwork Errors

The workers’ compensation system has strict timelines and requirements. Missing a deadline — whether for filing, medical evaluations, or appeals — can result in denial. Unfortunately, many injured workers don’t even realize they missed a step until it’s too late. An attorney keeps track of deadlines and ensures no detail slips through the cracks.


7. Employer or Insurance Company Disputes Your Claim

Sometimes, denial happens simply because your employer or their insurance company doesn’t want to pay. They may argue the injury isn’t serious, claim there were no witnesses, or insist that your story has inconsistencies. These tactics are designed to frustrate you into giving up. But with strong legal representation, you can challenge their claims and win.


What to Do If Your Workers’ Compensation Claim Is Denied

If your claim has been denied, don’t panic — and don’t give up. You have the right to appeal the decision through California’s Workers’ Compensation Appeals Board (WCAB). This process involves hearings, presenting evidence, and possibly testifying before a judge. Having an experienced workers’ comp lawyer by your side dramatically improves your chances of success.

Steps to take after a denial:

  1. Review the denial letter carefully.
  2. Gather medical records and witness statements.
  3. Consult with an attorney to prepare an appeal.
  4. File the necessary paperwork before deadlines expire.
