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 a claim is legitimate — and as an employer, you have every right to request or support that investigation. Understanding the boundaries of that investigation protects your business, helps you manage your Experience Modification Rate (E-Mod) — the multiplier that raises or lowers your workers' comp premium based on your claims history — and keeps your workforce honest.

Why Employers Should Care About Workers' Comp Investigations

Workers' comp fraud costs U.S. employers an estimated $34 billion per year, according to the Coalition Against Insurance Fraud. Every fraudulent or exaggerated claim that goes unchallenged gets absorbed into your loss runs — the record of claims against your policy. Worse, those losses can drive up your E-Mod, which directly increases what you pay in premiums at renewal. Fighting suspicious claims through proper investigation is not just acceptable; it is smart risk management.

Your insurance carrier typically handles investigations, but you should know what tools they and their investigators are legally permitted to use. Learn more about how claims affect your overall workers' comp insurance program.

What Investigators Are Allowed to Do

Investigators — whether hired by your insurer or a third-party Special Investigations Unit (SIU) — operate within both federal and state law. Here is what they are generally permitted to do:

1. Conduct Surveillance in Public Places

Investigators can legally watch, photograph, and video-record a claimant anywhere the public has access. This includes:

• Public streets, parking lots, and parks
• Stores, restaurants, and sporting events
• Social media posts that are publicly visible
• Activities visible from a public road or sidewalk (e.g., yard work, lifting, recreational sports)

They cannot record inside a private residence or in locations where a person has a reasonable expectation of privacy. Surveillance is one of the most common and effective tools used to uncover exaggerated or fabricated injuries.

2. Review Publicly Available Records

Investigators can access and review:

• Court records (civil, criminal, and prior workers' comp filings)
• Property records and motor vehicle registrations
• Business license filings (to detect unreported self-employment)
• Social media profiles set to public (Facebook, Instagram, TikTok, etc.)
• Published news articles and online activity

3. Conduct Interviews

Investigators may interview:

• Your employees and supervisors (as witnesses to the alleged incident)
• Neighbors or bystanders who observed the claimant's activities
• Former employers (to look for prior injuries or pre-existing conditions)

They cannot misrepresent who they are or use coercive tactics. Investigators must follow applicable state laws on recorded conversations, which vary — some states require all-party consent to record a phone call.

4. Request and Analyze Medical and Wage Records (With Proper Authorization)

With a properly executed medical release or through the claims process, investigators can review:

• Medical records related to the claimed injury
• Independent Medical Examination (IME) results — a second-opinion exam ordered by the insurer
• Wage and employment records to verify lost-time claims

5. Coordinate With Law Enforcement and State Fraud Bureaus

Most states have a dedicated workers' comp fraud unit within the state Department of Insurance or Attorney General's office. Investigators can refer suspicious cases for criminal prosecution. Penalties for workers' comp fraud can include fines, repayment of benefits, and even jail time.

What Investigators Are NOT Allowed to Do

There are clear legal limits. Investigators cannot:

• Trespass on private property to conduct surveillance
• Record conversations without consent where state law requires it (all-party consent states)
• Hack into or access private social media accounts, emails, or texts without authorization
• Impersonate law enforcement or government officials
• Harass, intimidate, or threaten a claimant
• Violate the Americans with Disabilities Act (ADA) or HIPAA in how they handle medical information
• Retaliate against a claimant for filing a valid claim — that exposes you as an employer to serious liability

Important: As an employer, you should never take adverse employment action against an employee solely because they filed a workers' comp claim. Consult your employment attorney on your specific obligations. We are brokers, not attorneys, and nothing here is legal advice.

What You Can Do as an Employer to Support an Investigation

You are not just a bystander. Here is how you can actively (and legally) support the process:

• Document everything immediately. Take photos of the accident scene, gather witness statements, and complete the First Report of Injury the same day.
• Report suspicions early. If something does not add up — the injury was reported Monday after a weekend off, there are no witnesses, or the claimant immediately hired an attorney — flag it with your carrier's SIU right away.
• Maintain a return-to-work program. A light-duty program reduces the cost of claims and can reveal whether a claimant's restrictions are genuine.
• Stay involved in the claims process. Ask your carrier for regular updates and review your loss runs at least twice a year.
• Work with a broker who monitors your claims. Our team at The Workers' Comp Experts reviews client loss runs proactively so we catch rising trends before they destroy your E-Mod.

If you operate in industries with higher fraud exposure — construction, agriculture, or trucking — your exposure is even greater. See our resource library for industry-specific guidance.

How Fraud Investigations Affect Your Premiums

Your E-Mod is calculated by NCCI (the National Council on Compensation Insurance) in most states, or by a state-specific rating bureau such as the WCIRB in California or PCRB in Pennsylvania. It compares your actual losses to expected losses for your industry class code — a classification that groups similar types of work together. A successful fraud investigation that reduces or eliminates a claim can prevent that claim from inflating your E-Mod and driving up future premiums.

Rates vary by state and class code — verify current loss costs with your broker.

Frequently Asked Questions

Can investigators follow an employee to their home?

Investigators can legally observe and record activity visible from public spaces, including the street in front of a home. They cannot enter private property, look through windows, or place recording devices on private property without consent. The line is the reasonable expectation of privacy.

Can I hire my own private investigator for a workers' comp claim?

Yes. As an employer, you can hire a licensed private investigator to gather evidence, subject to the same legal limits that apply to insurer-hired investigators. Coordinate with your carrier and legal counsel so the evidence is admissible and the process does not expose you to liability.

Can investigators look at a claimant's social media?

Yes — publicly visible social media posts are fair game. Photos and videos showing physical activity inconsistent with reported restrictions are regularly used as evidence. Private accounts cannot be accessed without the claimant's consent or a court order.

What happens if an investigator finds evidence of fraud?

The insurer can deny or reduce the claim, seek reimbursement of benefits already paid, and refer the matter to the state fraud bureau for criminal prosecution. As the employer, you may also have grounds to take disciplinary action — consult your employment attorney before acting.

Does fighting a fraudulent claim affect my relationship with my insurer?

No — it generally helps it. Carriers want employers who are engaged in claims management. An employer who reports red flags promptly and cooperates with investigations is viewed as a lower risk, which can positively influence your renewal terms.
