NICB, ISO ClaimSearch, and How Carriers Share Fraud Intelligence

Most large insurance fraud cases are not solved by looking at a single claim in isolation. They get solved, or significantly accelerated, by cross-carrier data. The three best-known tools in that space are ISO ClaimSearch, CLUE (Comprehensive Loss Underwriting Exchange), and NICB ForeWarn. Here is what they are, what they do, and how insurance fraud investigators actually use them.

ISO ClaimSearch

ISO ClaimSearch, operated by Verisk, is the largest cross-carrier claim-history database in the U.S. Carriers contribute claim data, and authorized users search it. On a fraud investigation, ISO ClaimSearch answers questions like:

• Has this claimant filed other claims across carriers?
• Are claims clustered around the same loss addresses?
• Do the same vehicles, providers, or attorneys recur across claims?
• Is the claimant's prior-loss history consistent with what they told your underwriter or adjuster?

Used correctly, ISO ClaimSearch surfaces the cross-carrier patterns that individual carrier SIUs can't see from their own data alone. It's a core tool on every substantive fraud file.

CLUE

CLUE, operated by LexisNexis, covers auto and property claim history. CLUE data is typically used at underwriting for risk assessment. In fraud investigations, CLUE supports:

• Verification of prior-loss history claimed (or concealed) by the applicant or claimant
• Identification of patterns of repeated losses at the same address
• Confirmation of prior-claim details on which the current claim is built

NICB ForeWarn

The National Insurance Crime Bureau (NICB) provides ForeWarn, a fraud-specific intelligence platform fed by member carriers. NICB ForeWarn is particularly strong for:

• Organized fraud ring identification (medical providers, repair shops, attorneys)
• Vehicle fraud: VIN history, salvage, and theft patterns
• Geographic concentration of fraud activity

NICB also supports multi-carrier task force operations and, crucially, referrals to state and federal criminal investigators.

State Fraud Bureaus and CDI / DOI Reporting

Most U.S. states have a state-level insurance fraud bureau within the Department of Insurance. California, for example, operates the CDI Fraud Division. Every California-licensed insurer is required to report suspected fraud referrals to them. The referral package is built from the carrier SIU file, and the state bureau decides whether the case gets investigated criminally.

Our case file post covers what a state-referral-ready fraud file looks like.

Coalition Against Insurance Fraud

The Coalition Against Insurance Fraud is the industry association that tracks fraud statistics. It advocates for stronger state legislation and publishes the widely-cited estimate that insurance fraud costs U.S. consumers over $300 billion per year. It isn't an investigation tool itself, but it's the clearinghouse for industry fraud data and policy.

Independent Investigator Access

A key operational question: when a carrier sends a fraud referral to an outside investigation firm, can the firm use ISO ClaimSearch, CLUE, and NICB tools on the carrier's behalf? Usually yes. Access flows through the carrier's own subscriptions and permissible-purpose authorization, or through the firm's subscriptions where the carrier delegates the work. Our FCRA and GLBA compliance post covers the permissible-purpose framework.

Link Analysis Across Carriers

The highest-value use of cross-carrier data is link analysis: connecting claimants, providers, addresses, attorneys, and vehicles across otherwise unrelated claims. Consider a medical provider who appears on twenty soft-tissue bodily injury claims at five different carriers, all represented by the same attorney. That is the kind of pattern ISO ClaimSearch and NICB ForeWarn surface.

Integrating Intelligence into the Investigation

A good fraud investigation uses cross-carrier data at two points:

1. Early, to triage the referral and scope the investigation proportionally.
2. Late, to confirm or dispute a scheme hypothesis developed through field investigation.

Our insurance fraud investigation services integrate ISO ClaimSearch, CLUE, and NICB tools into every qualifying referral. We produce case files formatted for both carrier use and state fraud bureau referral when warranted.
