If you receive a denial for your workers’ compensation claim in California, you can appeal the decision. Understanding how to proceed can help improve your chances of overturning the rejection and securing the benefits you deserve.
Review the reason for the denial
Start by carefully reviewing the denial letter. The insurance company will explain the reason for rejecting your claim. Common causes for denial include insufficient medical evidence, missing filing deadlines, or disputes over whether the injury occurred while performing job duties. Knowing exactly why the insurance company denied the claim will help you address the specific issues in your appeal.
Request a reconsideration or appeal
If you receive a denial, you can file a “Request for Reconsideration” or a formal appeal. To begin, you must submit additional evidence, such as updated medical records or statements from witnesses, to support your case. If the denial was based on insufficient medical evidence, providing more detailed medical reports can strengthen your appeal. Keep in mind that the state has strict deadlines for filing appeals, so make sure to act quickly.
Attend a hearing or mediation
If reconsideration doesn’t resolve the issue, you will likely need to attend a hearing before a workers’ compensation judge. Both you and the insurance company will have the chance to present evidence, and the judge will base their decision on the facts. Alternatively, California law may offer mediation, where a neutral third party helps both sides reach an agreement. If mediation doesn’t result in a settlement, the case will proceed to a hearing.
Decision and next steps
After the hearing or mediation, the judge will issue a written decision. If you win the appeal, the workers’ compensation benefits will be reinstated. If the decision isn’t in your favor, you can request a “Reconsideration” or file a “Petition for Writ of Review” with the California Court of Appeals, depending on the circumstances.
By staying organized, gathering the necessary evidence, and adhering to deadlines, you can increase your chances of a successful appeal even after a claim denial.
