Prosecution Pointers: Fighting Workers’ Compensation Fraud from Every Angle

Workers' Compensation (WC) fraud is one of the most costly and persistent challenges facing the insurance industry. According to the Coalition Against Insurance Fraud, WC fraud exceeds $34 billion a year. That number, which measures only premium and claimant fraud, becomes even larger when provider fraud is taken into consideration.

Workers' Compensation (WC) fraud is one of the most costly and persistent challenges facing the insurance industry. According to the Coalition Against Insurance Fraud, WC fraud exceeds $34 billion a year. That number, which measures only premium and claimant fraud, becomes even larger when provider fraud is taken into consideration. 

Premium fraud is committed by unscrupulous employers while claimant fraud involves workers misrepresenting injuries. Together, these two schemes drain billions from the system every year, driving up costs for honest businesses and consumers alike. Addressing both requires a comprehensive strategy that combines strong investigations, effective prosecution, and proactive prevention. 

The Hidden Cost of Premium Fraud

Workers’ compensation premium fraud is a massive and often-overlooked crime costing the United States an estimated $25 billion a year, nearly three times more than WC claimant fraud. Unscrupulous employers lie about payroll figures or misclassify job risk categories to avoid paying proper premiums, shifting those costs onto honest businesses that play by the rules.

Despite its scale, premium fraud cases can yield swift and significant results. They often lead to immediate, high-dollar restitution, sometimes ranging from $100,000 to several million dollars, because these employers committing fraud are frequently motivated to settle quickly and avoid criminal prosecution. For SIU professionals and claims teams, these cases represent an opportunity for meaningful financial recovery with a relatively clear evidentiary path.

Claimant Fraud: A $9 Billion Problem That Cannot Be Ignored

While premium fraud dwarfs it in raw dollar terms, WC claimant fraud costs over $9 billion annually in the United States and cannot be left unaddressed. It typically involves employees misrepresenting work injuries to collect benefits they do not deserve. Left unchecked, claimant fraud spreads, encouraging other employees to file dishonest claims and ultimately contributing to layoffs and even business closures.

For self-insured employers, the impact is especially severe, as they bear the full cost of fraud including wages, medical care, and administration. For others, the result is rising premiums across the board.

Understanding the five most common claimant fraud schemes is essential for anyone working to detect and investigate suspicious activity:

1.   Non-work injury claimed as work-related

2.   Completely fabricated injury

3.   Concealment of a pre-existing or prior injury

4.   Working while collecting workers’ compensation benefits

5.   Exaggeration of injury severity

Claims professionals and SIU investigators must be equipped to recognize these patterns and gather the evidence necessary to resolve suspicious activity effectively. Strong investigative work holds perpetrators accountable and sends a clear message that fraud will not be tolerated.

Beyond Investigation: The Case for a Prevention Strategy

Detection and prosecution are critical, but they are not enough on their own. Insurers, employers, consumers, law enforcement, government agencies, and community groups must work togetherto implement new strategies that reduce fraud before it occurs. Prevention is not just effective; it is also more cost-efficient than investigating and prosecuting fraud after the fact.

The traditional anti-fraud approach relies on dedicating resources to detect, investigate, and mitigate fraud losses through civil processes and, when warranted, criminal prosecution. This remains an essential allocation of resources. However, deterrence through media coverage of successful prosecutions has significant limitations. Criminal prosecutions are relatively few nationwide, and even fewer result in prison sentences. When a significant prosecution is obtained, media coverage is not guaranteed. Relying on deterrence alone is a hopeful wish like winning the lottery.

A more proactive model builds a Prevention Strategy alongside the investigative framework, drawing from proven approaches in the private sector.

A Real-World Prevention Model That Worked

When I served as a prosecutor in San Diego, I led a widespread workers’ compensation fraud prevention campaign modeled after private-sector advertising strategies. Just as companies like Coca-Cola and Chick-fil-A run ads to persuade consumers to choose their products, the San Diego campaign ran ads in high-profile media channels communicating a simple, direct message: workers’ compensation fraud is a felony that leads to incarceration.

The campaign tagline, “Don’t doit. Don’t tolerate it. Report it.” reached the community through thousands of public service announcements on television, freeway billboards, print ads, bus ads, posters, brochures, and other mediums. The results were remarkable: workers’ compensation claimant fraud dropped 43 percent in San Diego.

That outcome demonstrates what is possible when prevention is treated as a strategic priority rather than an afterthought.
