Where Insurance Fraud Actually Lives and Why It Keeps Getting Paid
This article explores which lines of business experience the most fraud, how fraud manifests in everyday claims, the red flags adjusters and SIU teams repeatedly encounter, why questionable claims still get paid and how carriers reduce leakage without relying on blanket denials.
Fraud doesn’t usually look like a crime scene. It looks like paperwork, timelines, and “close enough” decisions made under pressure.
In insurance, fraud rarely announces itself loudly. It shows up quietly embedded in volume, normalized by process, and overlooked because investigating it often costs more than paying it.
At Claim Analysis Group, our work consistently shows that fraud does not thrive where scrutiny is highest. It thrives where claims move fast, documentation is easy to produce, and investigation is viewed as impractical.

The red flags adjusters and SIU teams repeatedly encounter
Why questionable claims still get paid
How carriers reduce leakage without relying on blanket denials
The Lines of Business Most Exposed to Fraud
Based on observed claims behavior not assumptions, the following lines consistently show the greatest exposure to fraud and leakage risk:
Highest Exposure (Frequency + Aggregate Loss Impact)
Auto Casualty (Bodily Injury & Property Damage)
Property (Homeowners and CAT-related claims)
Travel Insurance
Workers’ Compensation
Moderate Exposure
Commercial General Liability
Specialty Property
Medical riders and supplemental coverage
Lower Frequency but High Severity
Life Insurance
Disability and Long-Term Care
Fraud risk is not defined by claim size alone. Some of the most persistent leakage occurs in low-dollar, high-volume lines, where individual claims receive minimal scrutiny and patterns are easy to miss.
How Fraud Manifests by Line of Business
Casualty Claims (Auto & General Liability)
Common fraud patterns
Staged or exaggerated accidents
Soft tissue injury inflation
Pre-existing conditions reframed as accident-related
Early attorney involvement driving escalation
Recurring red flags
Delayed injury reporting
Minimal vehicle damage paired with significant injury allegations
Repeated involvement of the same clinics or attorneys
Resistance to recorded statements
Why leakage occurs
Casualty claims are often resolved under economic pressure. Litigation risk, settlement efficiency, and diary volume can outweigh investigative depth even when concerns exist.
Property Claims (Homeowners & CAT Events)
Common fraud patterns
Claim padding after legitimate losses
Prior or unrelated damage included in new claims
Contractor-driven inflation and assignment of benefits abuse
Recurring red flags
Late notice of loss
Loss descriptions inconsistent with weather data
Contractor present before adjuster inspection
Recent policy inception or coverage increases
Why leakage occurs
Catastrophe environments prioritize speed. In high-volume scenarios, nuanced review becomes difficult even when red flags are visible.
Travel Insurance Claims (A Quiet but Persistent Risk)
Travel insurance is one of the most underestimated fraud exposure areas in the industry.
Common fraud patterns
Fabricated cancellation reasons
Medical documentation created after booking decisions
Inflated or unverifiable foreign medical receipts
Repeated claims across multiple trips or carriers
Recurring red flags
Documentation dated after cancellation events
Identical phrasing across multiple claims
Providers that cannot be independently verified
Policies purchased shortly before loss
In desk reviews conducted by Claim Analysis Group, travel fraud indicators rarely appear as isolated issues. They surface as repeating behaviors across time, vendors, and documentation patterns.
Why leakage occurs
Travel claims are typically low dollar and high volume. Investigation costs can exceed claim values, leading to reliance on document presence rather than document integrity. These small losses quietly aggregate into meaningful exposure.
Workers’ Compensation
Common fraud patterns
Exaggerated or prolonged disability claims
Injuries reported after disciplinary action or termination
Concurrent employment not disclosed
Recurring red flags
No witnesses to injury
Escalating treatment without diagnostic support
Refusal of light-duty or return-to-work options
Universal Fraud Red Flags Across All Lines
Regardless of coverage type, certain indicators consistently matter more than one-off anomalies:
Timeline inconsistencies
Repeated vendors, providers, or attorneys
Over-documentation that appears “too perfect”
Avoidance of recorded statements
Clustering of claims around policy changes
Similar narratives across prior losses
Fraud rarely appears as a single glaring issue. It appears as patterns over time.
Why Questionable Claims Still Get Paid
Fraud is not ignored it is managed within operational reality.
Claims are paid because:
Investigation costs exceed exposure
Litigation risk outweighs claim value
Proof thresholds are not met
Regulatory pressure favors prompt payment
SIU resources are finite
This reality explains why leakage reduction is not measured by denial rates but by early identification, segmentation, and strategic review.
How Carriers Reduce Leakage Without Overcorrecting
Effective fraud mitigation does not rely on blanket suspicion or automation alone.
What works
Early intervention before escalation
SIU desk reviews for low-dollar, high-volume claims
Pattern-based analytics instead of reactive case reviews
Vendor and provider concentration tracking
Clear role boundaries: SIU recommends; claims decide
Adjuster education focused on when to refer—not just how
What doesn’t
Investigating every red flag equally
Over-automation without human oversight
Waiting until litigation to act
Treating SIU as enforcement rather than insight
The Strategic Takeaway
The most fraud-prone claims are not always the most expensive.
They are the claims where:
Volume is high
Scrutiny is limited
Documentation is easy to fabricate
Investigation is viewed as “not worth it”
That is where leakage lives.
At Claim Analysis Group, we focus on bringing clarity to these overlooked spaces, supporting carriers and SIU teams with structured analysis, ethical review, and actionable insight.
