Claims | CNA

Special Investigations Unit (SIU)

Fraud costs an estimated $79 billion a year across the property and casualty/worker's compensation insurance industry, according to the the Coalition Against Insurance Fraud.  At CNA, we take fraud seriously. Our global Special Investigations Unit (SIU) works diligently to protect our policyholders by uncovering and investigating suspect claims, and collaborates with law enforcement agencies to assist with investigations leading to arrests and convictions of guilty parties.

Our best asset is our experience
Combating insurance fraud requires a deep and experienced team. Our SIU professionals have backgrounds in criminal and civil investigations, law enforcement, medical, business intelligence, analytics and claims handling. CNA’s Special Investigation professionals identify, investigate and deter insurance fraud while mitigating the risk of fraud losses to our policyholders.

Our SIU team has strategic partnerships with a global network of private investigators, antifraud legal counsel and some of the top Insurtech firms specializing in advanced predictive analytics and technology tools; who are able to assist with our investigative strategy in a timely and efficient manner.

Outstanding services and tools that identify fraud:

  • Scene inspection: Thoroughly investigates loss locations to validate the reported circumstances, obtain necessary photographs or source other pertinent information.
  • Evidence gathering: Collectively compiles information from multiple sources to affect the correct claims decisions, accomplished through interviews with involved parties and witnesses, and by obtaining court records and documentation that’s relative to the reported loss.
  • Surveillance: Accurately determines an injured worker’s level of activity to identify concurrent employment, which could render the claimant’s medical restrictions out of scope.
  • Background and medical records research: Comprehensively utilizes social network data mining and intelligent medical information tools to determine if an individual’s behavior coincides with a reported loss.


SIU tools and business partners include: 

  • Data analytics: Systematically sources medical provider treatment and billing records to identify patterns of abnormal behavior, in both individual claims as well as those spanning multiple claims and lines of business.
  • Social network data mining: Comprehensively pulls data from social networking sites to aid our SIU analysts as they gather information that may corroborate suspected fraud. Data mining assists with identifying possible associations between various parties to a claim, including claimants, medical providers, attorneys and witnesses. By using these tools, the SIU team can identify patterns of questionable behavior and activity that may otherwise remain undetected.
  • Link analysis: Visually connects networks and relationships, which aids our investigators when uncovering possible associations between involved parties to a claim.
  • National Insurance Crime Bureau (NICB): Enables us to quickly and efficiently identify high-risk claims, by researching specific data within CNA’s claims volume. In addition, the NICB provides jurisdictional expertise for each of our lines of business and acts as a resource for external fraud training. We also turn to the NICB’s Major Medical Fraud Task Forces for investigative support and to assist with large scale medical provider/organized fraud investigations.
  • Coalition Against Insurance Fraud (CAIF): Provides outreach, education and information on combating insurance fraud. As a member company, CNA receives practical tools, including the latest trend reports on fraud, legislative updates and other research that supports our anti-fraud efforts.
  • Federal/state/local enforcement agencies: Acts as an additional venue to refer suspect claims that have the potential for criminal investigation and prosecution.
