Red Flags on Workers' Comp Claims

Experienced workers' comp claim handlers and SIU analysts build a mental checklist of red flags that prompt closer investigation. Most red flags aren't evidence of fraud on their own. They're prompts to look more carefully. But when enough of them stack up, a compensability investigation or SIU referral is warranted.

Late Reporting

Injury reported hours, days, or weeks after the event. Common explanations are sometimes legitimate: the worker hoped to work through it, didn't want to cause trouble, or didn't think it was serious. But delayed reporting combined with other signals is one of the strongest fraud indicators.

Monday Morning Claims

Injuries reported first thing Monday or first thing after a weekend, with no witnesses and a claimed mechanism that could have occurred off-work. This is common for back, shoulder, and soft-tissue claims.

Post-Termination Claims

Claims filed right after the worker was fired, laid off, or given notice. The timing creates an obvious motive. Post-termination claims don't always mean fraud. A legitimate injury may have occurred before termination. But they require specific investigation.

Post-Discipline Claims

Similar to post-termination. The claim is filed shortly after the worker received discipline, was passed over for promotion, or had a confrontation with a supervisor.

Unwitnessed Injuries

Injuries reported in places where witnesses would normally exist, like a warehouse during a shift or an office with other workers present, but where no witnesses were there. This is worth investigating but not dispositive on its own.

Changing Story

The claimant's account of the injury evolves between:

• Initial report to the supervisor
• First notice of claim
• Recorded statement
• Medical provider intake
• Deposition

Substantive changes in mechanism, location, or timing are significant red flags. Our recorded statements post covers how to lock in the account.

Subjective-Only Injury

Pain, soft-tissue injury, stress, cumulative trauma, psychological injury. The concern isn't that these injuries aren't real. Most are. The issue is that objective medical evidence can't easily distinguish a real claim from an exaggerated one. These claims benefit disproportionately from surveillance and social media investigation.

Prior Claims Pattern

Multiple prior workers' comp claims, especially similar in nature. Prior bodily injury claims. Prior disability claims. ISO ClaimSearch and CLUE surface these consistently. See our prior claims and ISO ClaimSearch post.

Financial Distress

Pending bankruptcy, foreclosure, eviction, or job loss on the claimant's side creates a motive for indemnity. Financial distress alone isn't fraud. Financial distress combined with other red flags is an investigation priority.

Refusal of Light Duty

Refusing modified or light duty work without a specific medical basis. This is especially notable when the employer is offering accommodations within the restrictions.

Missed Medical Appointments

Pattern of no-shows at medical appointments paired with social media or observable activity at the same times.

Side Business Indicators

• Yelp, Google Business, or social media listings for services
• LinkedIn profile indicating current employment or self-employment
• Vehicles at the residence suggesting business activity
• Neighborhood activity patterns suggesting a business operating

See our undisclosed employment post.

Attorney Representation Immediately

Represented by counsel at first notice, especially by a firm known for aggressive soft-tissue litigation. Again, not dispositive. Many legitimate claimants have counsel. But a pattern of first-contact representation with specific firms is an investigation input.

Medical Red Flags

From the medical record:

• Symptom magnification on FCE or examination
• Inconsistent reports between providers
• Medication-seeking behavior
• Treatment shopping (multiple providers for the same complaint)
• Records inconsistent with the claimed mechanism

Provider Red Flags

Treatment concentrated with a single provider known to the carrier for aggressive soft-tissue treatment, high-volume claim files, or prior fraud referrals. Link analysis across claims sometimes surfaces provider patterns.

What to Do With Red Flags

Red flags should drive the investigation plan:

1. Activity check to verify residence and basic facts
2. Social media investigation to surface contradictions, see social media investigations
3. AOE/COE investigation to lock in the compensability story
4. Sub rosa surveillance where red flags and reserves justify, see when to order
5. Fraud investigation if the file crosses into SIU territory, see fraud case file post
