Core Responsibilities

Primary Functions

Lead end-to-end investigations into suspected insurance fraud by receiving referrals, validating claim histories, evaluating red flags, and determining investigative priorities to minimize indemnity and expense losses.
Conduct thorough interviews with claimants, insureds, witnesses, medical providers, employers, and other relevant parties using structured interview and interrogation techniques, documenting statements and assessing credibility for potential legal action.
Gather, secure, and analyze physical and digital evidence—police reports, medical records, billing statements, employment records, social media content, GPS/telematics data, and surveillance footage—maintaining strict chain-of-custody standards for admissibility.
Plan and supervise covert and overt surveillance operations, including coordination with private investigators, vendors, and internal resources to capture corroborating evidence of fraudulent activity while adhering to legal and ethical standards.
Perform open-source intelligence (OSINT) investigations and social media investigations to identify inconsistencies, hidden assets, undisclosed employment, or third-party involvement relevant to claims.
Execute forensic analysis of documents, images, and electronic files (metadata review, image tampering indicators, duplicate billing patterns) to detect alterations, misrepresentations, or fraudulent billing schemes.
Analyze claim, policy, and loss history using fraud analytics tools, statistical models, and case management systems to prioritize cases with the highest financial impact and fraud likelihood.
Prepare and maintain detailed, well-documented investigative reports and case files suitable for internal adjudication, subrogation actions, civil recovery, and criminal prosecution, clearly articulating findings, evidentiary support, and recommended next steps.
Coordinate with legal counsel to evaluate cases for potential civil litigation or referral to law enforcement and assist with subpoenas, depositions, and trial preparation as needed.
Interface with external stakeholders including local, state, and federal law enforcement agencies, prosecutors’ offices, regulatory bodies, medical providers, and third-party vendors to share evidence, seek warrants, and support prosecutions.
Testify in administrative hearings and court proceedings as an expert or fact witness, presenting findings in a clear, credible manner and defending investigative methodology and conclusions under cross-examination.
Identify and document fraud schemes and emerging trends (e.g., staged accidents, phantom billing, identity theft, organized rings) and collaborate with analytics teams to update detection rules and red-flag criteria.
Conduct field inspections and property examinations, including on-site evidence collection, scene documentation, photography, and measurements to validate or refute claim statements.
Initiate subrogation, restitution, or recovery actions by identifying liable third parties, preserving evidence, calculating loss exposure, and coordinating with recovery and legal teams to recover paid benefits.
Utilize specialized SIU and case management systems (e.g., XactAnalysis, Guidewire, i-Sight, eCase) to document investigative activity, manage evidence, track litigation milestones, and maintain audit-ready records.
Maintain up-to-date knowledge of state insurance codes, statutes, civil discovery rules, HIPAA, privacy laws, and investigatory boundaries to ensure compliance and reduce legal risk.
Provide coaching, mentorship, and technical guidance to junior investigators and claims adjusters on fraud indicators, investigative techniques, and documentation best practices to raise the organization’s fraud detection capability.
Collaborate cross-functionally with claims, underwriting, actuarial, and data science teams to improve referral quality, reduce false positives, and design fraud-prevention controls embedded into claims adjudication workflows.
Negotiate and manage vendor contracts for surveillance, forensic accounting, medical record retrieval, and legal support—reviewing deliverables, validating costs, and ensuring vendor compliance with protocols and timelines.
Monitor and track case outcomes, financial recoveries, and key performance indicators (investigative hit rate, recovery per case, prosecution rate) and prepare executive-level summaries to demonstrate SIU impact and ROI.
Execute complex background investigations on claimants, insureds, service providers, and suppliers for potential conflicts of interest, prior fraud indicators, or licensing irregularities.
Escalate high-risk or multi-jurisdictional cases to senior leadership and coordinate centralized responses, including task force involvement and multi-party evidence consolidation.
Ensure confidentiality and integrity of sensitive investigative data, employing secure data handling, encryption, and access controls to protect personally identifiable information (PII) and HIPAA-regulated information.
Provide fraud awareness training sessions for claims staff, agents, and brokers to improve early detection, referral accuracy, and internal controls against fraudulent activity.
