Workers' comp fraud: employee, employer and provider schemes

Workers' compensation fraud comes in three forms: claim fraud by employees, premium fraud by employers, and billing or referral fraud by medical providers and others who profit from claims. Employers feel the first when a suspicious claim lands on their loss record, and they are the actors in the second. Every state treats fraud as a crime and most run a fraud bureau, but definitions, reporting duties and penalties differ, so check your state's rules and your carrier's special investigations unit (SIU) process.

How big the problem is

Nobody knows the exact figure, because undetected fraud is by definition unseen. The Coalition Against Insurance Fraud, an insurer, regulator and consumer group, has published estimates in the tens of billions of dollars a year for the comp line, with premium fraud by employers accounting for most of it in its analysis (Coalition workers' comp report, 2023). Treat those totals as rough industry estimates, not audited numbers. What matters for an employer is the mechanism: honest employers pay for premium fraud through higher manual rates and for claim fraud through loss experience.

Type 1: employee claim fraud

This is what most people picture. Common patterns:

• Faking or staging an injury, or claiming an injury that happened off the job (a weekend sports injury reported Monday morning).
• Exaggeration: continuing to claim disability while working elsewhere or engaging in activities that contradict the restrictions.
• Working while collecting temporary disability benefits without reporting the earnings.
• Misrepresenting history, such as denying a prior injury to the same body part.

Red flags that justify a closer look, not proof: no witnesses to a Monday-morning injury, a claim filed just before or after a layoff, discipline or resignation, a history of similar claims, a reluctance to accept modified work or to see a doctor the carrier proposes, and treatment that exceeds what the described mechanism would produce. A flag is a reason to report promptly and accurately, not to accuse. Most claims are legitimate, and wrongly accusing a worker invites retaliation liability.

Type 2: employer premium fraud

Premium for workers' comp is based on payroll in each class code, multiplied by a rate, modified by the experience modification rate. Each part is a target:

The consequence of getting caught goes beyond back premium. Depending on the state, premium fraud can be a felony, carry fines and restitution, and lead to cancellation and placement in the assigned risk and residual markets for workers' comp market. An audit finding is not automatically fraud, since an honest misunderstanding of a class code is not fraud, but knowingly reporting wrong numbers is.

Type 3: provider and third-party schemes

Medical providers, attorneys, pharmacies and "claim runners" can profit from comp claims. Typical schemes include billing for services not provided, upcoding, unnecessary procedures, kickbacks for referring patients, and compound-drug or testing arrangements priced far above a fee schedule. These are generally caught by carrier bill review, state audits and data analytics (fraud analytics: how insurers detect fraud). The employer's role is limited, but if you hear that a clinic is pushing treatment you did not direct, tell the adjuster.

What employers should do

1. Report and investigate every injury promptly. Take a written statement the same day and note witnesses, as described in reporting a workplace injury: what employers must do. Fast facts beat slow suspicion.
2. Tell the adjuster, not the employee. If you suspect fraud, give your concerns, with specifics, to the carrier or third-party administrator; its SIU decides whether to investigate or refer it to the state.
3. Don't investigate yourself in ways that create liability. Surveillance, social-media review and background checks have legal limits that vary by state. Let the SIU or counsel run those.
4. Know your state's reporting rule. Many states require insurers to report suspected fraud to a fraud bureau or the insurance department, and many extend immunity for good-faith reports. See California for one detailed example, where the Department of Insurance investigates comp fraud, and use the workers' comp and benefits requirements by state for others.
5. Keep your own house clean. Reconcile payroll with state wage reports, document any contractor's coverage, and tell your broker about operations changes before the audit, not after.
6. Use the dispute tools. A suspicious claim can be contested, with an independent medical examination (independent medical examination) where the state allows it, and defended with documented facts. If a third party caused the injury, the carrier may pursue subrogation.

Hypothetical example

Say a 15-employee drywall contractor reports $200,000 of payroll, all in the lower-rated clerical class, plus two crews paid in cash. At audit the carrier finds payroll tax filings that do not match, check stubs for crew members, and a claim from a worker the contractor says never worked there. The auditor reclassifies the payroll to drywall rates, charges the additional premium, and refers the matter to the state's fraud unit. Beyond the back charge, the contractor risks a criminal referral, a cancelled policy and a hard market afterward.

Key takeaways

• Comp fraud is claim fraud (employees), premium fraud (employers) and provider fraud; the Coalition Against Insurance Fraud's analysis puts premium fraud as the largest by dollars.
• Red flags are reasons to report with facts, not to accuse; wrongful accusation creates its own liability.
• Premium fraud typically involves hidden payroll, wrong classifications, contractor misclassification or reincorporating to shed a bad mod.
• Penalties, reporting duties and immunity rules differ by state; start with the workers' comp and benefits requirements by state.
• Report suspicions in writing to the carrier and let the SIU investigate.
