Workers Comp Investigators: What Are They Allowed to Do?

Workers' comp investigators are legally permitted to conduct surveillance in public spaces, interview witnesses, review public records, and gather evidence that verifies or disputes a claimant's reported injury. As an employer, understanding what investigators can — and cannot — do helps you manage claims effectively, reduce fraud losses, and keep your Experience Modification Rate (E-Mod) under control.

Why Employers Hire Workers' Comp Investigators

Fraudulent workers' comp claims cost U.S. employers and insurers an estimated $7–$10 billion annually, according to the Coalition Against Insurance Fraud. Even one inflated claim can raise your E-Mod — a number calculated by NCCI (National Council on Compensation Insurance) or your state's rating bureau that directly affects your premium. A higher E-Mod means higher premiums for years to come.

Carriers often deploy their own Special Investigations Units (SIU). You can also work with your broker or a third-party investigator when a claim looks suspicious. The goal is always the same: verify that the injury happened the way it was reported and that the disability is as severe as claimed.

What Investigators Are Legally Allowed to Do

Investigators operate within federal and state privacy laws. Here is what is generally permitted across most jurisdictions:

1. Public Surveillance

An investigator can observe and record a claimant anywhere the general public can see them — a parking lot, a park, a sporting event, a job site, a social gathering. If someone is visible from a public road or sidewalk, recording is typically lawful. This is the most common investigative tool.

2. Video and Photography in Public

Investigators may take photos or video in public spaces without notifying the subject. This footage is regularly used as evidence in claim disputes and hearings. Many claims have been denied after video showed a claimant performing physical activities that supposedly exceeded their reported restrictions.

3. Social Media Research

Publicly visible social media profiles — posts, photos, check-ins, tagged locations — are fair game. If a claimant posts photos of themselves hiking while claiming a total back disability, that content can be collected and used as evidence. Investigators do not need to hack accounts or befriend the claimant under false pretenses; public posts are enough.

4. Witness Interviews

Investigators can speak with coworkers, neighbors, or anyone else willing to talk voluntarily. They can interview your employees about what they witnessed at the time of the alleged injury. They cannot coerce witnesses or misrepresent themselves as law enforcement.

5. Public Records Review

Court records, property records, business license filings, vehicle registrations, and other public government documents are all accessible. An investigator might discover that a claimant who says they cannot work is actually running a side business.

6. Activity Checks and Skip Tracing

Investigators can verify a claimant's location, employment history, and activity patterns using legally available databases and public information — a process sometimes called skip tracing.

What Investigators Are NOT Allowed to Do

Boundaries exist. An overzealous investigation can expose your business or carrier to liability. Investigators generally cannot:

• Enter private property without permission — no trespassing on the claimant's yard, home, or fenced area
• Record inside a private residence — what happens inside a home is protected
• Intercept private communications — wiretapping or accessing private messages is illegal under federal law (Electronic Communications Privacy Act)
• Hack or access private social media accounts — only public content is usable
• Impersonate law enforcement — investigators must be honest about who they are if directly asked
• Harass or stalk — excessive, repeated surveillance in a way that constitutes harassment can create legal problems
• Access medical records without authorization — HIPAA applies; medical records require a signed authorization or court order

Rules can vary by state. Some states have specific statutes governing insurance investigations. Always work with your carrier's SIU or a licensed private investigator who knows your state's laws.

The Employer's Role in the Investigation Process

You are not a passive bystander. As the employer, you play an active role in protecting your business from fraud. Here is what you should do:

• Report claims promptly. Early reporting gives investigators the best opportunity to gather fresh evidence.
• Document everything at the scene. Witness statements, security footage, and accident reports collected immediately after an incident are invaluable.
• Flag suspicious claims to your carrier. You do not need proof — you just need a reasonable basis to request an SIU referral.
• Cooperate fully with investigators. Provide requested records, access to your premises, and employee contact information as allowed by law.
• Maintain a return-to-work program. Offering modified duty reduces the duration of claims and limits the window for fraud to occur.

How Fraud Affects Your Premiums

Your E-Mod is recalculated annually based on your actual claim history versus what is expected for your industry. A fraudulent or inflated claim that goes unchallenged increases your actual losses — and pushes your E-Mod above 1.0, which means a premium surcharge. In states where NCCI sets loss costs, even one large claim can follow your business for three policy years. Rates vary by state and class code — verify current loss costs with your broker.

Our licensed team works with employers across all 50 states, including high-risk industries like construction, agriculture, and manufacturing, to manage claims proactively. Contractors may also want to explore our performance bond services, where claims history matters just as much.

Special Considerations for High-Risk Industries

Certain industries see disproportionately high claim frequency, making investigations more common:

• Construction: Falls, sprains, and equipment injuries are common — and sometimes fabricated or exaggerated
• Agriculture: Seasonal workers and H-2A visa employees present unique claims challenges; see our agricultural workers' comp resources
• Trucking and fleet: Long-haul drivers file claims across multiple states, complicating oversight
• Restaurants and hospitality: High turnover and repetitive-motion claims require careful documentation

Frequently Asked Questions

Can a workers' comp investigator follow an employee in their car?

Yes, in most states an investigator can follow someone on public roads and document their movements. This is considered observation in a public space and is generally lawful, provided it does not cross into harassment or stalking.

Can investigators access an employee's private Facebook or Instagram?

No. Investigators cannot hack accounts, create fake profiles to gain access, or use deceptive means to view private content. However, anything posted publicly — visible without logging in or sending a friend request — can be collected and used as evidence.

As an employer, can I request an investigation on a claim I find suspicious?

Absolutely. You should report your concerns to your carrier or broker right away. Most insurers have a Special Investigations Unit (SIU) that handles referrals. You do not need definitive proof — a reasonable suspicion based on inconsistencies in the claim is enough to request a review.

What happens if fraud is confirmed?

If the investigation uncovers fraud, the carrier can deny or terminate the claim, seek reimbursement of benefits already paid, and refer the matter to state insurance fraud bureaus or law enforcement. Many states have dedicated workers' comp fraud prosecution units. Confirmed fraud can also result in civil liability for the employee.

Will an investigation affect my relationship with my employees?

Done professionally and through proper channels (your carrier's SIU), investigations are standard business practice. The investigation targets the claim — not the employee's character broadly. Maintaining a safe workplace, a clear injury reporting policy, and a return-to-work program is the best long-term strategy for managing claims fairly and limiting fraud exposure.
