Prepared by Yazdchi Law
In California, workers' comp fraud means knowingly making a false statement to get benefits you are not owed, or to avoid paying benefits that are owed. The law covers injured workers, employers, doctors, lawyers, and claims administrators alike. An honest mistake, a disputed claim, or being seen on video doing normal activity within your medical limits is not fraud by itself. California law makes this a felony, and both the Department of Insurance and local prosecutors investigate reports.
What is considered workers' compensation fraud in California?
Workers' compensation fraud in California is knowingly making a false or misleading statement, in writing or out loud, to get workers' comp benefits that are not owed, or to avoid paying benefits that are owed.
California law addresses this in two places. Insurance Code section 1871.4 makes it a crime to knowingly file a false or fraudulent claim for workers' comp benefits. It is also a crime under that section to make a knowingly false statement to deny benefits a worker is owed. Labor Code section 3820 adds civil penalties for the same kind of false statements. Labor Code sections 3822 and 3823 add a yearly fraud warning notice, plus a duty for insurers and others to report suspected fraud by medical providers. Insurance Code section 1871.4 and Labor Code section 3820 both remain current law.
Present or cause to be presented any knowingly false or fraudulent written or oral material statement in support of, or in opposition to, any claim for compensation for the purpose of obtaining or denying any compensation, as defined in Section 3207.
This law does not single out workers. It applies equally to claims administrators, insurance companies, doctors, lawyers, and employers. The California Department of Insurance (CDI) describes workers' comp fraud as a tempting target for criminals, ranging from a worker who exaggerates an injury to a doctor who bills for treatment never given. Workers' comp fraud is a felony, and both CDI's Fraud Division and local district attorneys investigate it.
California's workers' comp system is also no-fault. You do not have to prove your employer did something wrong to receive benefits for a workplace injury, only that the injury happened on the job. That design matters here: a claim is not fraudulent just because no one was at fault, or because the claims administrator disputes it.
What does not count as workers' comp fraud?
An honest mistake, a disputed claim, or normal activity caught on camera within your doctor's restrictions is not workers' comp fraud, because fraud requires a knowing, intentional false statement.
California's fraud law is an intent crime. CDI explains that a prosecutor must prove the person knew a statement was false and intended to use it to get or deny benefits. Without that intent, there is no fraud, even when a form has an error or two people remember an accident differently.
A claims administrator disputing your claim is not fraud either. Insurers may question whether an injury is work-related, request a medical evaluation, or deny a claim they believe does not qualify. That is a normal part of a contested claim, not a crime. If you think an insurer is unreasonably delaying or denying your claim without a real dispute behind it, that is a separate issue called bad faith. See our guide to insurance bad faith and delayed benefits for more on that issue.
Surveillance is normal too, and being watched is not proof of anything by itself. Insurance companies may legally record your public activity to compare it with your reported limits. Being seen carrying a light bag or smiling at a store is not fraud if it still fits inside the restrictions your doctor set. The problem only starts if you tell your doctor or the claims administrator something that is not true.
| Usually fraud | Usually not fraud |
|---|---|
| Inventing an injury that never happened | Reporting a real injury with no witness present |
| Working a second, undisclosed job while claiming total disability | Light activity that stays inside your doctor's written restrictions |
| A doctor billing for treatment never provided | A doctor billing for treatment you actually received |
| An employer hiding payroll to cut its insurance bill | An employer who disputes whether an injury happened at work |
How does employer and provider fraud happen in California?
Workers' comp fraud is not only about workers. Doctors, lawyers, claims administrators, and employers can all be charged under the same fraud law.
CDI has investigated schemes where doctors and lawyers entice, pay, or conspire with others to build false or exaggerated claims, over-treat patients, or over-prescribe addictive medication. Insurance companies pay those bills, then pass the cost on to every employer who buys a policy.
Employers commit a related but separate crime when they operate without required workers' comp coverage. Illegally failing to secure that insurance is a misdemeanor under Labor Code section 3700.5 (see our explanation of the no-coverage penalty), and CDI's Fraud Division investigates it alongside Insurance Code violations. An employer can also commit fraud directly, for example by under-reporting payroll to its insurer to pay a lower premium.
None of this changes how your own claim should move forward. If you suspect an employer or a medical provider is doing one of these things, keep handling your own honest claim while you report what you saw.
How do I report suspected workers' comp fraud in California?
Report suspected workers' comp fraud to the California Department of Insurance (CDI) or to local prosecutors. The Division of Workers' Compensation (DWC) processes claims, but it does not investigate fraud.
Use CDI's online fraud reporting portal, or contact the Fraud Division regional office for your county. You can also call the department's consumer hotline at 1-800-927-4357 for help finding the right office, or take a report straight to the district attorney in your county. Reports to CDI can be made anonymously.
A good-faith report is protected. Insurance Code section 1872.51 and section 1879.5 say a person who files a good-faith report of suspected insurance fraud with CDI is not subject to civil liability for making that report.
DWC keeps your claim moving, schedules hearings, and resolves disputes about your benefits, but it does not investigate fraud. Send a fraud report to CDI or local prosecutors, and keep handling your own claim through the normal workers' comp process at the same time.
How can an honest claimant protect against a fraud accusation?
Stay consistent, keep your own records, and get medical and legal help early. These steps protect you whether or not anyone ever raises a fraud question.
Describe your symptoms and limits the same way every time: to your doctor, to the claims administrator, and in any paperwork. Small, honest differences in memory are normal, but a pattern of conflicting statements is often what triggers a closer look.
Keep copies of your medical records, your claim form, wage statements, and any letter from the claims administrator. If a dispute or a fraud question ever comes up, your own paper trail is often the fastest way to clear it up.
If your claim is denied or you are accused of fraud, do not just accept it or argue alone. See our guide on what to do after a workers' comp claim denial, and talk to an attorney before you answer questions from an investigator.

Fraud or concealment by an employer can also extend how long you have to file a claim: see our page on California workers' comp filing deadlines for the standard one-year rule and its exceptions.

Frequently Asked Questions
Can I get in trouble for an honest mistake on my workers' comp claim?
No. California's fraud law punishes a knowing false statement made to get or deny benefits, not a mistake. The Department of Insurance has to show you intended to defraud the system, not just that a form was wrong or your memory of an event was off. If you catch your own error, tell your claims administrator and correct it in writing.
Is it fraud if the insurance company films me on a good day?
No. Insurers can legally watch your public activity to compare it with your reported limits. Being seen smiling, driving, or carrying light groceries is not proof of fraud if it still fits inside your doctor's restrictions. Fraud requires a knowing false statement, not a single good moment on video.
Can my employer or my doctor commit workers' comp fraud too?
Yes. California's fraud law applies to claims administrators, doctors, lawyers, and employers as much as it applies to workers. Common examples include billing for treatment never given, over-prescribing medication, and hiding payroll to pay a lower insurance premium. An employer that illegally skips required workers' comp coverage faces a separate charge under Labor Code section 3700.5.
Where do I report suspected fraud in a California workers' comp claim?
Use the Department of Insurance's online fraud reporting portal, call its consumer hotline at 1-800-927-4357, or contact your local district attorney's office. The Division of Workers' Compensation handles claims but does not investigate fraud itself. A good-faith report to the department is protected from civil liability under Insurance Code sections 1872.51 and 1879.5.
Is being investigated for fraud the same as being convicted?
No. Workers' comp fraud is a felony under Insurance Code section 1871.4, and Labor Code section 3820 adds separate civil penalties for the same conduct. But an investigation is only a fact-finding step. The Fraud Division or local prosecutors gather evidence first, and a case must still be filed and proven in court. You have the right to an attorney at every stage.
What should I do if I am accused of workers' comp fraud?
Stay consistent and truthful about what you can and cannot do, and keep your own copies of medical notes and claim forms. An accusation can lead to a denied claim, so review your options on our denied claim guide. Speak with a workers' comp attorney before you answer questions from a fraud investigator.
