Detecting Patterns of Exaggerated Damages in Demand Packages Using AI — What SIU Investigators Need to Know

Special Investigations Units are under pressure. Demand packages are bigger, medical and repair documentation is messier, and the tactics used to inflate damages grow more sophisticated every quarter. Yet cycle times are shrinking and leakage targets are unforgiving. This is exactly where Nomad Data’s Doc Chat changes the game. By reading entire claim files—demand packages, medical records, repair estimates, loss summaries, and more—side by side and at once, Doc Chat surfaces inconsistencies and exaggeration patterns that manual review routinely misses.

For SIU investigators across Auto, General Liability & Construction, and Property & Homeowners lines, the challenge is not merely volume—it’s the interplay between documents, dates, codes, and narratives scattered across thousands of pages. Doc Chat automatically cross-references statements, CPT/ICD-10 codes, invoices, Xactimate line items, photos, and policy terms, then highlights the red flags that matter in seconds. If your focus includes AI review demand package exaggeration, demand letter fraud detection, or how to identify excessive damages in claims, this article unpacks the end-to-end approach and shows why Doc Chat has become an indispensable SIU ally.

The SIU Reality: Exaggeration Patterns Are Subtle, Cross-Document, and Line-of-Business Specific

Exaggeration rarely lives on a single page. In Auto, a bodily injury demand may cite persistent pain, future care, and wage loss, but the police report shows a low-impact collision, no airbag deployment, and no ambulance transport. In General Liability & Construction, an incident report may describe minor exposure, yet OSHA logs, subcontractor agreements, and change orders suggest unrelated causes or pre-existing hazards. In Property & Homeowners, a water mitigation invoice could stack equipment days well beyond IICRC guidance, while roofer estimates and hail swaths don’t align with the date of loss.

The nuance for an SIU investigator is connecting these sources: FNOL forms, policy declarations and endorsements, recorded statements, EUO transcripts, medical records and billing ledgers, provider notes, radiology reports, CPT/ICD-10 coding, repair estimates and supplements, photos with EXIF data, appraisals, meteorological data, inspection and engineer reports, lien notices, EOBs, coverage letters, ISO claim reports, and subrogation notices. Doc Chat’s advantage is simple: it reads every page with identical rigor and then lets you ask natural-language questions to test consistency and credibility across the entire file.

How SIU Investigators Handle Demand Package Review Manually Today

Today’s manual process forces investigators to skim thousands of pages and take notes, usually under deadline. In Auto BI or GL bodily injury matters, SIU teams triage demand letters, compare narratives to recorded statements and police reports, and attempt to reconcile medical billing with coding and treatment windows. In Property claims, SIU validates scope, labor hours, O&P, and mitigation line items against photos, moisture logs, and vendor contracts. In construction incidents, SIU cross-checks jobsite daily reports, subcontract agreements, COIs, and incident logs against the loss narrative in the demand package.

The friction points are persistent: inconsistent formats, boilerplate language, templated physician narratives, changing claimant stories, coding that doesn’t match the mechanism of injury, mitigation invoices with questionable equipment days, Xactimate estimates that stack line items, and dates that don’t align. Humans get tired. They miss non-obvious linkages across 2,000–10,000 pages. The outcome is leakage, extended litigation, or settlement values not supported by facts in the file.

Doc Chat’s Approach: From Document Piles to Defensible, Page-Cited Findings

Doc Chat ingests entire claim files—often thousands of pages—without headcount. It extracts, summarizes, and cross-checks across demand packages, loss summaries, medical records, repair estimates, FNOL forms, coverage letters, and more. And because it is trained on your SIU playbooks and standards, it recognizes your definitions of red flags and applies them uniformly, case after case. You can interrogate the file in real time: “List all CPT codes and units billed by provider,” “Show every instance of ‘guarded gait’ and link to source pages,” “Compare MRI findings with mechanism of injury reported in the police report,” “Highlight mitigation equipment days that exceed IICRC standards by more than 20%.”

Every answer includes citations back to the original page, allowing SIU, counsel, and leadership to verify instantly. This page-level explainability is exactly what top carriers require for regulators, reinsurers, and litigation teams—and it is core to how Doc Chat operates. As a strategic product for claims organizations, Doc Chat is described in depth here: Doc Chat for Insurance.

AI Review Demand Package Exaggeration: A Practical SIU Framework

SIU work is hypothesis-driven. Doc Chat transforms your hypotheses into precise, automated checks that run across the entire file. It flags linguistic and coding anomalies, timeline gaps, scope creep, and mismatched narratives between demand letters and supporting documents. By coupling natural-language Q&A with automated extraction, you can “ask and verify” instantly, even on 10,000-page files.

Cross-Document Consistency Checking

Demand package narratives often hinge on statements like “permanent impairment,” “guarded gait,” “radiating pain,” and “future care needs.” Doc Chat finds every occurrence, compares descriptions across provider notes, correlates to objective findings (e.g., MRI read, range-of-motion notations), and contrasts them with the accident dynamics in the police report or incident report. If a claimant reports restricted activity but social, employment, or therapy notes in the file indicate full function, Doc Chat surfaces the contradiction with citations.

Medical Coding and Billing Anomalies

Doc Chat compiles CPT/HCPCS codes, ICD-10 diagnoses, units, and modifiers from medical bills and EOBs; it aligns them to dates of service, prescriber, and facility. It flags patterns consistent with upcoding (e.g., 99215 where documentation supports a lower-level visit), unusual frequency of certain modalities, duplicate billing across providers, and billings not supported by chart notes. For Auto and GL bodily injury, it highlights treatment initiated long after the date of loss without medical justification, and gaps suggesting opportunistic care. It also calls out repetitive boilerplate phrases across multiple claimants associated with a suspected provider.

Property Scope and Mitigation Validation

In Property & Homeowners, Doc Chat audits Xactimate estimates, supplements, and mitigation invoices against photos, adjuster notes, inspection reports, and moisture logs. It compares equipment days and categories (e.g., air movers, dehumidifiers) against IICRC guidance and moisture readings. It flags stacked O&P, line-item duplication, and materially inconsistent “before/after” photos. For hail or wind, it can incorporate third-party weather data supplied by the carrier to check whether the alleged storm event aligns with NOAA or vendor hail swaths near the reported date of loss.

General Liability & Construction: Documentation Integrity

In GL and construction incidents, Doc Chat reviews incident reports, OSHA logs, site safety plans, toolbox talks, daily reports, subcontractor agreements, COIs, change orders, and emails. It assesses whether the alleged mechanism of injury, timing, and cause are supported by contemporaneous documentation. It flags contracts or indemnity terms that may mitigate exposure, and inconsistencies between the demand’s narrative and jobsite records.

What “Demand Letter Fraud Detection” Looks Like in Practice

Doc Chat is purpose-built for the patterns SIU investigators repeatedly encounter in demand packages. The following are representative checks it performs across Auto, GL & Construction, and Property files:

Auto Bodily Injury: It contrasts vehicle damage severity from appraisals and photos with claimed injury severity, notes lack of acute care, late treatment starts, or aggressive treatment patterns without escalation of objective findings. It highlights duplicate PT/chiro modalities, unusually frequent passive therapies, and narrative repetition that mirrors known boilerplate from specific law firms or providers.

General Liability & Construction: It aligns witness statements with OSHA logs and daily reports, tests timecards against alleged injury times, and traces subcontractor indemnity or COI gaps. It checks whether medical causation discussions are supported by contemporaneous incident documentation—and cites the pages that matter.

Property & Homeowners: It reconciles moisture maps, readings, and equipment logs with billed days; compares roofer or contractor estimates against inspection photos and engineers’ notes; and flags storm-date mismatches using carrier-provided weather verifications. It detects scope inflation and non-covered upgrades embedded in the demand.

How Doc Chat Works: Purpose-Built AI Agents for SIU

Doc Chat combines large-scale document ingestion with insurance-specific reasoning. It can process approximately 250,000 pages per minute and return consistent, playbook-aligned outputs for your team. You can ask free-form questions—“Show every date of service billed for CPT 97110 and list supporting chart note excerpts”—and receive answers with page citations. Because Doc Chat is trained on your standards, it behaves like a seasoned SIU analyst who never gets tired, forgets a page, or misses a footnote.

This capability is more than summarization. As we describe in Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs, real insurance work requires inference across inconsistent documents—connecting codes, narratives, and policy language that were never written in one place. Doc Chat operationalizes that inference at scale with page-level evidence, so your SIU findings are both fast and defensible.

From Manual Review to Automated Insight: A Side-by-Side Look

Manual SIU Review Today

SIU investigators manually assemble timeliness charts; read every provider note to line up with billed services; search for duplicates and upcoding; compare police reports or incident logs to injury narratives; and test repair scope against photos and inspections. They then craft case memos, outline red flags, and prepare EUO questions or defense referrals. This can take days or weeks on a complex file, with fatigue increasing the risk of oversight.

Automated with Doc Chat

Doc Chat ingests the entire file and presents you with:

• A timeline of key events (date of loss, treatment, diagnostics, invoices, supplements) with source-page links.
• Side-by-side comparisons of narrative claims versus objective records (police/incident reports, imaging findings, jobsite logs, moisture readings).
• Medical billing rollups: CPT codes, units, modifiers, frequency, and provider mapping against chart documentation.
• Property estimate audits: duplicated line items, O&P stacking, mitigation equipment days vs. moisture logs and IICRC guidance.
• Contract and coverage insights: indemnity/hold-harmless terms, policy endorsements, and exclusions relevant to causation or scope.

With this foundation, you can generate EUO question sets, draft SIU referrals, or produce negotiation-ready summaries in minutes. The system’s accuracy and repeatability mean your investigative energy is spent on strategy, not search.

High-Impact Uses by Line of Business

Auto

Doc Chat compares police reports, crash photos, vehicle appraisals, and repair supplements with claimed injury severity and treatment patterns. It flags low-impact collisions with disproportionate care, highlights gaps between imaging and narrative complaints, and identifies billing for modalities that lack chart support. It also traces treatment clusters across related cases that may indicate a PI mill.

General Liability & Construction

For premises incidents and jobsite injuries, Doc Chat aligns incident reports, witness statements, OSHA logs, daily reports, subcontract agreements, COIs, and emails to test causation and responsibility. It surfaces indemnity provisions and additional insured endorsements that may transfer or limit exposure. When demand packages include expansive non-economic damages, Doc Chat pinpoints inconsistencies across statements and records that undermine credibility.

Property & Homeowners

Doc Chat audits Xactimate and contractor estimates line by line, checks mitigation invoices against moisture logs, and evaluates roof or siding claims against engineer notes and carrier-provided weather data. It identifies non-covered upgrades presented as repairs, stacked overhead, and questionable labor hours. It also ties back to policy language—deductibles, sublimits, and exclusions—referencing exact pages for coverage determinations.

AI Meets Human Judgment: The Right Operating Model for SIU

SIU success depends on professional skepticism and judgment. Doc Chat does not replace that; it amplifies it. Think of it as a faultless reader and extractor that instantly assembles the facts and inconsistencies across the file. You remain the decision-maker who weighs context, intent, and negotiation strategy. This collaborative model is explored in Reimagining Claims Processing Through AI Transformation and in The End of Medical File Review Bottlenecks, which detail how page-cited AI output elevates human-led determinations.

Business Impact: Faster SIU, Lower Leakage, Stronger Defense

The economic case is straightforward. Manual review forces your most experienced investigators to spend hours hunting for facts that Doc Chat can assemble in seconds. By removing the rote reading, you compress cycle time, expand SIU coverage, and catch more leakage-causing exaggerations before negotiation hardens. Teams adopting Doc Chat report step-change gains in speed and accuracy, consistent with the results discussed in Great American Insurance Group’s AI transformation.

Consider the measurable impacts Doc Chat enables:

Time savings: Large files that previously required days to summarize are now review-ready in minutes. SIU investigators can triage more cases per week without sacrificing depth.

Cost reduction: Fewer outside vendor reviews, reduced overtime, and lower litigation spend driven by stronger early-case insights and better negotiation leverage.

Accuracy and completeness: Uniform, playbook-based extraction ensures nothing falls through the cracks—every code, clause, clause exception, and line item is examined consistently, every time.

Defensibility: Every finding is backed by page citations, bolstering auditability and courtroom readiness.

Deep-Dive: How Doc Chat Helps You Identify Excessive Damages in Claims

If your priority is to identify excessive damages in claims across Auto, GL & Construction, and Property, Doc Chat operationalizes the exact checks SIU teams need:

Auto BI Demand Packages

Doc Chat aligns the following for credibility checks:

Mechanism vs. medical: Police report crash dynamics, photos, airbags, initial symptoms; compared with later medical narratives and diagnostics. Doc Chat flags when subjective complaints escalate while objective findings remain unchanged.

Billing reasonableness: CPT/HCPCS rollups by provider/facility; unit counts; frequency vs. clinical justifications from chart notes. Doc Chat highlights passive modalities overuse and duplicate billings across clinics.

Lost wage claims: Compares employment documentation and treatment dates; checks for overlaps with timecards or unrelated leave records within the file.

Life care plan demands: Contrasts projected care needs with treating physician notes and imaging; cites pages undermining claimed permanency.

General Liability & Construction Demands

Doc Chat tests injury causation against incident logs, OSHA records, witness statements, and jobsite dailies, then reviews subcontract agreements and COIs for risk transfer. It triangulates billing to chart support, highlights late treatment onset, and points to contract clauses that limit exposure or trigger indemnity—each with page citations.

Property & Homeowners Demands

Doc Chat reconciles Xactimate and contractor estimates with inspection reports and photos; audits mitigation invoices against moisture logs and IICRC guidance; checks storm claims against carrier-provided weather verification; and flags upgrade line items masquerading as repairs. It then references policy language to indicate coverage limitations and exclusions with exact-page anchors.

Real-Time Q&A for SIU: From Hypothesis to Proof in Seconds

Doc Chat’s greatest strength for SIU is how quickly it moves you from a hypothesis to evidence. You can ask questions like:

• “List all treatment gaps longer than 21 days and show adjacent chart notes and any rationale.”
• “Extract all mentions of ‘permanent impairment’ and align with diagnostic imaging findings.”
• “Compare mitigation equipment billing days to moisture readings and flag where days exceed expected guidelines by 25%+.”
• “Identify O&P stacking across base estimate and supplement and cite line items.”
• “Show every indemnity or hold harmless clause relevant to subcontractor X.”

Because Doc Chat’s outputs are linked to the page, you can immediately export the relevant sections to an SIU memo, EUO outline, defense referral, or settlement brief. This compresses days of document grind into minutes of analysis and decision-making.

From Intake to Disposition: Where Doc Chat Fits in SIU Workflow

Triage: Rapidly score incoming demand packages for exaggeration risk using your playbook. Prioritize high-signal files for deeper SIU review.

Investigation: Generate a timeline, extract codes, reconcile narratives, and verify invoices and estimates. Ask targeted questions to probe red flags.

EUO and Defense Prep: Create question sets and topic outlines with embedded citations. Provide counsel with annotated packets, not raw PDFs.

Negotiation: Anchor counteroffers in objective contradictions and unsupported line items, with sources linked for immediate verification.

Referral and Reporting: Produce regulator-ready or NICB-style summaries with consistent formats and full audit trails.

Proven at Scale: From Days to Minutes

We routinely see SIU and complex-claims teams cut review times by orders of magnitude. In one example, medical summaries that took weeks to compile in bodily injury cases are now generated in under an hour with gap analysis, code rollups, and narrative inconsistencies highlighted automatically. For property matters, mitigation invoice audits and scope checks that occupied adjusters for days are completed in minutes, with moisture logs, photos, and line items reconciled and cited. These gains echo the transformations described in The End of Medical File Review Bottlenecks and the claims modernization efforts shared in Reimagining Claims Processing Through AI Transformation.

Security, Auditability, and Change Management

SIU leaders must satisfy compliance while transforming process. Doc Chat is built for enterprise security and governance, with consistent, page-cited outputs that stand up to internal audits, reinsurer reviews, and litigation scrutiny. Teams typically adopt Doc Chat in a phased manner: start by drag-and-dropping claim files to build trust through observed accuracy, then integrate with claims systems and document repositories. Carriers often see near-immediate productivity gains using this approach, as discussed in the GAIG experience: Reimagining Insurance Claims Management.

Implementation: White-Glove in 1–2 Weeks

Nomad Data deploys Doc Chat with a service model that captures your SIU rules—those unwritten heuristics that live in experts’ heads—and encodes them into actionable, repeatable checks. Most SIU teams are fully operational in 1–2 weeks, starting with simple uploads and Q&A, then moving to structured summaries and integration. Our premise is simple: AI should adapt to your process, not the other way around. You can learn more about our product, use cases, and deployment model here: Doc Chat by Nomad Data.
