Workers Comp Investigators: What Are They Allowed to Do?

Workers' comp investigators are legally allowed to conduct surveillance, review public records, interview witnesses, and gather evidence to verify whether an injury is legitimate and consistent with the reported claim. As an employer, knowing exactly what investigators can — and cannot — do helps you work more effectively with your insurer and protect your business from fraudulent claims that drive up your Experience Modification Rate (E-Mod) — the multiplier applied to your base premium based on your claims history.

Why Claims Investigations Matter to Employers

Every workers' comp claim affects your E-Mod. A higher E-Mod means higher premiums. According to the National Council on Compensation Insurance (NCCI) — the organization that sets rating rules in most states — your E-Mod is recalculated annually based on your losses over a three-year period. Fraudulent or exaggerated claims inflate those losses directly.

The Insurance Information Institute estimates workers' comp fraud costs employers and insurers billions of dollars each year. When your carrier assigns an investigator, they are working to protect both their interests and yours. Understanding the process helps you support the investigation properly.

What Investigators Are Legally Allowed to Do

Investigators operate under state law, and their permitted activities vary slightly by jurisdiction. However, the following are generally allowed across most states:

• Video surveillance in public spaces. An investigator can film or photograph a claimant anywhere the general public can observe them — parking lots, parks, sporting events, grocery stores, public sidewalks. No consent is required.
• Social media monitoring. Investigators can review publicly visible posts, photos, check-ins, and videos on platforms like Facebook, Instagram, TikTok, and LinkedIn. If a claimant publicly posts a video of themselves doing yard work while claiming a debilitating back injury, that is fair game.
• Review of public records. Court records, property records, business licenses, motor vehicle records (where permitted by the Driver's Privacy Protection Act), and bankruptcy filings are all searchable.
• Interviews with witnesses. Coworkers, neighbors, or other individuals who voluntarily agree to speak can be interviewed. Investigators cannot force anyone to talk.
• Contacting the claimant directly. Investigators may call or visit a claimant to verify information, as long as contact does not cross into harassment or intimidation.
• Activity checks and canvassing. An investigator may knock on a claimant's door, observe from the public street, or check activity patterns over multiple days.
• Database searches. Investigators can cross-reference workers' comp claim databases, prior injury records, and fraud bureaus. Many states maintain fraud reporting systems through their Department of Insurance.

What Investigators Are NOT Allowed to Do

There are firm legal limits. Investigators who violate these boundaries can expose your carrier — and potentially your business — to liability. They cannot:

• Enter private property without permission. Peering over a fence, entering a fenced yard, or placing cameras on private property is typically illegal without consent.
• Record inside a private residence. Even if a claimant can be seen through a window, recording inside a home is generally prohibited.
• Access private social media accounts by creating fake profiles, hacking, or impersonating someone else. The Computer Fraud and Abuse Act (CFAA) and state privacy laws prohibit deceptive access.
• Intercept phone calls or private communications without consent — this is a federal wiretapping violation under the Electronic Communications Privacy Act (ECPA).
• Harass, intimidate, or threaten the claimant or their family members.
• Access medical records without authorization. Medical records are protected under HIPAA; investigators must follow proper legal channels (subpoena or claimant authorization) to obtain them.

Your Role as the Employer During an Investigation

As the employer, you have both rights and responsibilities during a workers' comp investigation. Here is how to support the process effectively:

• Report claims promptly. Late reporting is one of the biggest claim cost drivers. File the First Report of Injury as soon as you become aware — most states require this within a few days of the incident.
• Preserve evidence. Secure surveillance footage, incident reports, witness statements, and any equipment involved. This documentation strengthens any investigation.
• Cooperate with your insurer's SIU. Your carrier's Special Investigations Unit (SIU) handles suspected fraud. Provide them with employment records, attendance logs, and job descriptions.
• Document return-to-work offers. If you offer modified duty and the employee declines, document it in writing. This can affect benefit payments and claim outcomes.
• Do not contact the claimant about the investigation. Direct contact related to a fraud investigation should go through your carrier or legal counsel. Missteps here can create retaliation claims.
• Report suspected fraud to your state's fraud bureau. Most states have a dedicated workers' comp fraud hotline through the Department of Insurance. Using it is both your right and often your duty.

How Investigation Outcomes Affect Your Premium

A successful fraud investigation can result in a claim being denied or reduced, which directly protects your E-Mod. Recall: your E-Mod is calculated using your actual losses compared to what is expected for your industry (class code — a classification system that groups similar businesses together for rating purposes). Fewer legitimate losses mean a lower E-Mod, which means lower premiums.

Carriers in NCCI states use loss costs (base rates set by NCCI) that your broker then applies your E-Mod and other factors to in order to calculate your final premium. Rates vary by state and class code — verify current loss costs with your broker.

Special Considerations by Industry

Some industries see higher fraud rates and more intensive investigation activity:

• Construction: High-severity injuries and self-employment misclassification make this a frequent target. If you are managing subcontractors, visit our contractor bonding and compliance page to understand how coverage gaps happen.
• Agriculture: Seasonal workers and H-2A visa employees present unique verification challenges. Learn more on our agricultural workers' comp page.
• Trucking and fleet operations: Long-haul injuries are difficult to witness, making investigative documentation especially important for fleet employers.

FAQ: Workers' Comp Investigators

Can a workers' comp investigator follow an employee?

Yes. An investigator can follow and observe a claimant in any public space. They can film activity at a grocery store, gym, sporting event, or on public streets. They cannot follow someone onto private property or into a private residence without consent.

Can investigators look at an employee's Facebook or Instagram?

Yes — but only publicly available content. If a claimant's profile is set to public, investigators can screenshot and use any posts, photos, or videos. They cannot create fake profiles or use deceptive means to access private accounts.

How long can surveillance last on a workers' comp claim?

There is no universal time limit. Surveillance typically continues until the carrier has enough evidence to make a determination, the claim closes, or the cost of investigation outweighs its benefit. Investigations on long-duration claims can span weeks or months.

What should I do if I suspect an employee is committing workers' comp fraud?

Notify your insurance carrier's SIU immediately and document your suspicions with any supporting evidence — attendance records, witness accounts, social media screenshots, etc. You can also report suspected fraud to your state's Department of Insurance fraud division. Do not confront the employee directly about fraud, as this can create legal exposure.

Does a fraud investigation affect my workers' comp premium right away?

Not immediately. Your E-Mod is recalculated annually. If a fraudulent claim is denied or reduced as a result of an investigation, your loss history improves and your E-Mod — and premium — should reflect that in the next rating period. Timely investigation and claim closure matter significantly.

Protect Your Business and Your Premium

Understanding what workers' comp investigators can and cannot do keeps you compliant, cooperative, and protected. The best way to minimize fraud's impact on your premiums is to work proactively with a knowledgeable broker who reviews your claims data regularly and helps you access markets built for your risk profile.
