What is workers’ compensation insurance fraud?

Workers’ compensation insurance fraud system takes many forms, including the following:

  • Medical providers
    • bill for inappropriate or unnecessary treatment
    • submit bills with improper medical codes
    • bribe indigent individuals to be “injured worker” patients
  • Insurers / claims administrators / third-party administrators (for self-insured employers)  
    • cause payments to be made to nonexistent claimants or medical providers
    • refer patients or clients to medical providers or attorneys for compensation
    • issue excessive payments to an attorney or medical provider in return for a kick-back
    • backdate documents in an attempt to avoid penalties for delays in benefit payments or alter documents to support an unjustified denial of a claim
  • Employers
    • misclassify workers to lower premium rates (high-risk jobs classified as low-risk)
    • report inaccurate payroll to lower premium rates (either under-report payroll to imply fewer employees, or over-report payroll as if workers were experienced journeymen with lower risk of injury).
    • misreport claims history (omit work injuries) to lower premium rates. 
  • Workers submit fraudulent claims for fabricated or exaggerated work-related injuries or illnesses.

How does DIR combat workers’ compensation fraud?

Senate Bill 1160 and Assembly Bill 1244, both of which became effective on January 1, 2017, added important new tools to combat workers’ compensation fraud in the State of California.  These tools included a new automatic lien stay provision as well as a process for suspending (i.e. excluding) providers from the workers’ compensation system, and in some cases, consolidating and disposing of their liens.

  • Lien Stays During Criminal Prosecution

Labor Code section 4615 places an automatic stay on liens filed by or on behalf of physicians and providers who are criminally charged with certain types of fraud. The automatic stay prevents those liens from being litigated or paid while the prosecution is pending. DIR publishes a list of physicians and providers whose liens are stayed pursuant to this statute.

To assist participants in the workers’ compensation system and the public, DIR tries to identify all liens filed by or on behalf of these physicians and providers and mark those liens as “stayed” in the Electronic Adjudication Management System (EAMS).  However, EAMS may not reflect all liens that are subject to the automatic stay.  If you have information about additional businesses that should be covered by the stay, please notify DIR’s Antifraud Unit.

  • Provider Suspensions

Pursuant to Labor Code section 139.21, DIR suspends physicians, practitioners, and other providers from participating in the workers’ compensation system if they have been convicted of certain kinds of crimes, have been excluded from the Medicare system, or have lost their professional license. The Administrative Director of the Division of Workers Compensation issues a Notice of Suspension that becomes effective 30 days later unless appealed.

Suspension from participating in the workers’ compensation system means that they may no longer provide or obtain payment for any treatment, evaluation, or other service related to a claim for workers’ compensation.  A physician, practitioner, or provider who has been suspended due to conviction of a covered crime is also subject to having all pending lien claims consolidated and dismissed in a special lien proceeding, unless they can prove the liens did not arise from the conduct or activity that led to their suspension. For information about pending lien consolidations please visit the Special Adjudication Unit Calendar webpage.
