SIU Case Narrative AI Agent
AI agent assembles evidence and drafts special investigations unit case files that speed investigations, strengthen referrals, and improve the quality of regulatory reporting.
AI-Powered SIU Case Files for Faster, Stronger Fraud Investigations
Special investigations units carry heavy caseloads, yet a large share of an investigator's time is spent assembling documents, transcribing statements, and writing narratives rather than investigating. Evidence sits across claims systems, email, third-party databases, and recorded calls, and pulling it together into a coherent, referral-ready case file can take days. The SIU Case Narrative AI Agent compresses that work by gathering evidence, indexing it, drafting a chronological narrative, and preparing referral packages that meet fraud-bureau standards.
The AI in insurance market reached USD 10.36 billion in 2025, and 76% of insurers have implemented at least one GenAI use case (EY Global Insurance Outlook 2025). Insurance fraud costs U.S. consumers more than USD 300 billion a year according to the Coalition Against Insurance Fraud, and investigations that move faster recover more and deter more. The NAIC Model Bulletin on AI, adopted by 24 states and D.C. as of March 2026, requires documented governance for AI systems that influence investigation and claims outcomes, including tools that assemble evidence and draft case narratives.
What Is the SIU Case Narrative AI Agent?
It is an AI system that collects investigation evidence from multiple sources, applies fraud-indicator libraries, and drafts a structured, source-cited case file that investigators review and route as a referral or disposition.
1. Core capabilities
- Evidence aggregation: Pulls claim records, documents, ISO ClaimSearch hits, telematics, public-records data, and statement transcripts into one indexed case repository.
- Narrative drafting: Generates a chronological case narrative in the carrier's house style, with each statement traceable to a cited source.
- Red-flag detection: Applies configurable fraud-indicator libraries and links every flag to the supporting evidence item.
- Referral packaging: Formats case files to match state fraud bureau and NICB intake requirements for complete, compliant referrals.
- Interview support: Summarizes recorded statements, highlights inconsistencies, and surfaces follow-up questions for the investigator.
- Audit and versioning: Maintains a full version history of the narrative and evidence, preserving a defensible chain for litigation and regulatory review.
2. Evidence inputs and sources
| Evidence Type | Source System | Normalized Output |
|---|---|---|
| Claim file data | Claims platform | Indexed claim summary |
| Loss documents | Document repository | Tagged exhibit with metadata |
| Prior-claim history | ISO ClaimSearch | Cross-claim linkage record |
| Recorded statements | Telephony, transcripts | Time-stamped statement summary |
| Telematics and GPS | Vehicle/IoT feeds | Event timeline entry |
| Public records | Third-party data | Verified identity/asset record |
| Provider data | Medical/repair networks | Billing anomaly record |
3. Case-strength interpretation
| Case Score | Interpretation | Recommended Action |
|---|---|---|
| 85 to 100 | Strong evidence of fraud | Prepare referral to fraud bureau |
| 65 to 84 | Substantial red flags | Escalate for full investigation |
| 45 to 64 | Mixed indicators | Assign for additional evidence |
| 25 to 44 | Weak indicators | Monitor and document |
| 0 to 24 | No material indicators | Close with rationale |
Investigators can adjust any score after review, and the fraud investigation workflow agent can route qualifying cases directly into the SIU queue.

How Does the SIU Case Narrative Process Work?
It ingests investigation evidence, normalizes and indexes each item, applies indicator libraries, drafts the case narrative, and assembles a referral package for investigator review.
1. Case assembly workflow
| Step | Action | Timeline |
|---|---|---|
| Intake | Receive assigned case and claim references | Immediate |
| Evidence pull | Gather documents and third-party data | 1 to 3 minutes |
| Normalization | Index and tag each evidence item | Under 1 minute |
| Indicator scan | Apply fraud red-flag libraries | Under 1 minute |
| Narrative draft | Generate chronological case narrative | 2 to 4 minutes |
| Referral format | Build bureau/NICB-ready package | Under 1 minute |
| Investigator review | Human edit and approval | Investigator paced |
| Total | Draft-ready case file | Under 10 minutes |
2. Statement and interview handling
The agent ingests recorded-statement transcripts, produces concise summaries, and flags inconsistencies between statements, documents, and the claim timeline. It proposes follow-up questions and organizes prior statements so investigators can prepare for interviews faster and identify contradictions that merit further probing.
3. Referral quality control
Before a case is marked referral-ready, the agent checks completeness against the target bureau's intake checklist: identity verification, loss chronology, cited exhibits, and a clear statement of the suspected scheme. Missing elements are flagged so the investigator can close gaps before submission, reducing rejected or returned referrals.
What Benefits Does the SIU Case Narrative Agent Deliver?
Faster case assembly, more consistent narratives, higher-quality referrals, and stronger regulatory reporting across the investigation lifecycle.
1. Investigation efficiency gains
| Metric | Without AI | With AI |
|---|---|---|
| Time to assemble a case file | 8 to 16 hours | Under 30 minutes |
| Narrative drafting time | 3 to 6 hours | Minutes |
| Evidence indexing | Manual, inconsistent | Automated and uniform |
| Referral rejection rate | 15% to 25% | Under 10% |
| Investigator cases per month | Baseline | 30% to 50% more |
2. Consistency and defensibility
Because every narrative statement is tied to a cited source and every change is versioned, case files are uniform across investigators and defensible under discovery. SIU leadership gains confidence that referrals meet the same evidentiary bar regardless of who worked the file.
3. Better regulatory reporting
The agent structures data so mandatory fraud reporting to state bureaus is accurate and timely. Standardized fields and complete narratives reduce the back-and-forth with regulators and improve the carrier's standing in market conduct examinations.

How Does It Comply with Regulatory Requirements?
Full audit trails, role-based access to sensitive data, and alignment with NAIC and IRDAI governance frameworks.
1. Compliance framework
| Requirement | Agent Capability |
|---|---|
| NAIC Model Bulletin (24 states and D.C., Mar 2026) | Documented AIS Program, logged automated actions |
| Unfair discrimination laws | Indicator libraries reviewed for prohibited factors |
| State fraud reporting mandates | Bureau-formatted, complete referral packages |
| IRDAI Sandbox 2025 | Compliant investigation workflows for India |
| Data privacy and access control | Role-based permissions, encrypted evidence store |
The agent never issues a referral or disposition on its own; it prepares the file and preserves the audit trail, leaving the decision to the investigator and SIU leadership.
What Are Common Use Cases?
It is used for staged-loss investigations, medical and repair fraud files, organized-ring case building, backlog reduction, and regulatory reporting across property, casualty, and health lines.
1. Staged and Suspicious Loss Investigations
When a claim shows indicators of a staged or exaggerated loss, the agent assembles the claim timeline, telematics, prior claims, and statements into a single narrative that highlights inconsistencies. Investigators start from a complete, cited draft rather than a blank page.
2. Medical and Repair Provider Fraud
For claims involving suspect providers, the agent pulls billing records, cross-references prior-claim patterns, and documents anomalies such as upcoding or phantom services. The resulting file supports both civil recovery and referral to fraud bureaus.
3. Organized Fraud Ring Case Building
The agent links related claims, shared identities, addresses, and providers across multiple files to help investigators document the structure of an organized scheme. Consolidated narratives make complex, multi-claim rings easier to present to law enforcement.
4. Backlog and Caseload Reduction
By automating evidence assembly and drafting, the agent lets each investigator carry a larger caseload without sacrificing quality. Aging cases are triaged and drafted quickly, reducing the backlog that often forces premature closures.
5. Regulatory and Bureau Reporting
The agent produces standardized case files that satisfy state fraud-bureau intake and mandatory reporting requirements. Consistent, complete submissions improve acceptance rates and strengthen the carrier's compliance posture in examinations.
