Rapid Analysis of Large Demand Packages in Catastrophe Claims: Preventing Post-Disaster Fraud – SIU Investigator (Property & Homeowners)

Post-disaster surges create a perfect storm for insurance fraud. After a hurricane, wildfire, flood, or severe wind event, Property & Homeowners carriers are inundated with massive catastrophe demand packages from contractors, public adjusters, and plaintiff attorneys. SIU investigators must sift through thousands of pages of receipts, repair invoices, loss summaries, contents inventories, photos, and correspondence—under intense time pressure—to stop leakage and protect policyholders. The challenge: evidence is dispersed across inconsistent documents, and the red flags are subtle—duplicate receipts, inflated labor rates, double-billed emergency services, and contradictions between sworn statements and invoices.

Nomad Data’s Doc Chat is purpose-built to solve this problem. It is a suite of insurance-trained, AI-powered agents that ingest entire CAT claim files, analyze them in minutes, and expose inconsistencies with page-level citations. For SIU, Doc Chat functions as a cat claims fraud detection tool—helping teams analyze large demand packages for fraud, flag duplicate receipts across multiple files (including across jurisdictions), benchmark labor and materials against market norms, and cross-check facts against policy forms and endorsements. With real-time Q&A and automation tailored to your investigative playbook, Doc Chat gives SIU investigators the speed, accuracy, and defensibility they need when every hour counts.

Why Catastrophe Property & Homeowners Demand Packages Are a Fraud Magnet

Catastrophe (CAT) events shift the entire market. Materials and labor are scarce, policyholders are anxious, and contractors race to meet demand. For SIU investigators, the Property & Homeowners line presents a unique risk profile after CAT events:

Volume spike: A single storm can multiply open claim counts by 10x, with each claim file ballooning to thousands of pages, including public adjuster demand letters, contents inventories, repair estimates, and sworn statements in proof of loss (SSPOL).
Document variability: Receipts, repair invoices, loss summaries, contractor proposals, Xactimate/Simsol estimates, and emails arrive in inconsistent formats—often scanned, sometimes handwritten, and rarely standardized.
Dispersed evidence: Fraud indicators hide in small print on receipts, mismatched dates in photos, or fine text in endorsements and exclusions. Signals are spread across the FNOL, adjuster notes, EUO transcripts, and third-party vendor reports.
Market distortion: After CAT events, labor rates and material costs rise—but bad actors push beyond reasonable increases. Detecting true market shifts versus opportunistic markup requires context and comparison.
Organized patterns: Rings and traveling contractors may reuse receipts or boilerplate language across multiple insureds and carriers, often spanning counties or states.

For a Property & Homeowners SIU investigator, this means the most telling clues are cross-document, cross-claim, and cross-time. Traditional tools are not designed to connect these dots at CAT scale.

The Manual SIU Process Today: Thorough, Essential—and Unsustainably Slow at CAT Scale

Historically, SIU teams rely on meticulous human review. Investigators read the FNOL, policy declarations, endorsements and exclusions, loss summaries, contractor estimates (e.g., Xactimate line items), and demand packages. They verify receipts against permits, licenses, and supplier catalogs; scrutinize paid amounts on repair invoices; cross-check dates of loss, weather footprints, and damage descriptions; and confirm whether contents inventories align with the home’s square footage and occupancy history.

While this diligence is critical, the manual process breaks down during CAT surges:

Time pressure: Teams must triage hundreds of complex files while simultaneously preparing EUOs, preserving subrogation, and meeting regulatory timelines.
Fragmented clues: A duplicate receipt or double-billed tarping charge may be buried on page 784 of a public adjuster packet, while the conflicting note sits on page 23 of an adjuster diary 60 days earlier.
Fatigue and inconsistency: Even the best SIU professionals can miss small but costly anomalies when document counts stretch into the thousands.
Limited cross-claim visibility: Teams often lack a fast method to compare a new demand package against other policyholders’ receipts across the same event, contractor, or region.

The result is leakage, longer cycle times, and the risk of overpaying or litigating cases that could have been resolved with stronger, earlier evidence—evidence that was present but practically invisible.

Doc Chat as a Cat Claims Fraud Detection Tool: Analyze Large Demand Packages for Fraud in Minutes

Doc Chat for Insurance transforms SIU’s workflow by automating the cognitive heavy lifting across massive Property & Homeowners claim files. It ingests entire catastrophe demand packages—receipts, repair invoices, loss summaries, contractor estimates, photos, emails, proofs of loss, EUO transcripts, and more—then answers your questions with page-level citations. When SIU needs to analyze large demand packages for fraud, Doc Chat becomes the control tower.

CAT-Scale Ingestion and Normalization

Doc Chat processes thousands of pages in minutes, standardizes diverse file types, and constructs a navigable index. Whether files arrive as multi-PDF bundles, scanned images, or exports from claim systems, SIU investigators can immediately ask questions like “List every line item for emergency services,” “Which receipts appear more than once?” or “Where do labor rates exceed our CAT rate caps by more than 20%?”—and get instant answers with the page links to validate.

Duplicate Receipt and Vendor Pattern Detection

Fraud rings often reuse the same receipts, SKU lists, or invoice templates across multiple claimants. Doc Chat highlights exact and near-duplicate receipts within a file and across files, even when images are cropped or black-and-white. If you need to flag duplicate CT claims receipts AI-style after a coastal wind event in Connecticut, Doc Chat can surface receipt IDs, vendor names, totals, and dates that repeat across policyholders in the same CAT footprint, including fuzzy matches where amounts or dates are shifted.

Labor and Material Benchmarking Post-Disaster

Price increases happen after CATs, but opportunistic markups do too. Doc Chat benchmarks labor and materials by referencing the rates found in the claim documents and comparing them to your approved vendor schedules or third-party references (e.g., regional Xactimate line items, RSMeans guidance, or your internal CAT rate tables). It flags suspicious deltas—like demolition labor marked up 65% above CAT-adjusted benchmarks—and points to each cited page.

Policy Alignment: Coverage A/B/C/D, Special Limits, and Endorsements

Coverage and causation are intertwined in property claims. Doc Chat reads policy forms, endorsements, and declarations to connect the demand package back to coverage (Coverage A – Dwelling, B – Other Structures, C – Contents, D – ALE/LOU). It surfaces special limits (e.g., jewelry, firearms, cash), sub-limits, deductibles (including hurricane/wind deductibles), and anti-concurrent causation or wear-and-tear exclusions that could limit or deny certain line items. Ask: “Identify every line item in the demand that conflicts with the vandalism exclusion” or “List contents claimed above special limits and their proof sources.”

Timeline, Causation, and Photo Consistency Checks

Doc Chat creates a chronology from FNOL through settlement, aligning dates of loss, weather reports, contractor site visits, and the sequence of repairs. It verifies whether claimed damage predates the event or whether photos’ metadata contradicts invoice dates. For contents claims, it cross-references purchase dates, credit card statements, and receipts. It can also point out missing links—e.g., a major roof replacement invoice with no permit record in the municipal packet.

Entity Resolution Across the CAT Event

SIU often needs to connect dots across multiple claims: a contractor who appears under slight name variants, a shared mailing address used by different insureds, or the same public adjuster leveraging near-identical language across demand letters. Doc Chat performs entity resolution to cluster related vendors, public adjusters, and law firms, surfacing cross-claim patterns with evidence citations.

Real-Time Q&A That Cites Every Answer

Ask natural-language questions—“Which tarping line items appear to be billed twice?” “Show any receipts that appear in other open claims from this CAT” “Which receipts are missing tax, itemization, or vendor contact details?”—and Doc Chat responds instantly with a list of answers linked to the source pages. This transparency is essential for defensibility with regulators, reinsurers, and courts, as highlighted in the Great American Insurance Group webinar replay detailing page-level explainability.

Key Documents and Forms Doc Chat Reads for Property & Homeowners SIU

Doc Chat thrives on the document diversity inherent to Property & Homeowners catastrophe claims. It reads and connects:

Catastrophe demand packages from public adjusters and plaintiff counsel
Receipts and repair invoices (e.g., Home Depot/Lowe’s, roofing suppliers, remediation vendors)
Loss summaries, contents inventories, and ALE/LOU logs
FNOL forms and adjuster notes/diaries
Sworn Statement in Proof of Loss (SSPOL)
EUO transcripts and recorded statements
Policy declarations, endorsements, exclusions, and conditions
Contractor estimates and Xactimate/Simsol breakdowns
Municipal permits, inspection reports, and code compliance notes
Weather reports, NOAA storm footprints, and third-party peril data
ISO ClaimSearch/CLUE reports and prior loss histories
Bank/credit card statements supporting large contents purchases
Photos, videos, and image metadata

By correlating across all of these, Doc Chat surfaces inconsistencies a human might never see in time—especially during a CAT surge.

What Doc Chat Automates for SIU—Step by Step

1) Automated Intake, Classification, and Completeness

On upload, Doc Chat classifies documents, builds a contents table, and runs a completeness check. It identifies missing items—permits for structural repairs, ALE receipts for hotel stays, or licenses for out-of-state contractors—and drafts a ready-to-send request list.

2) Fraud Signal Extraction and Cross-Checks

Doc Chat applies your SIU playbook to the file. Common CAT fraud flags include:

Duplicate receipts across claimants or within the same file
Invoice line items inconsistent with policy coverage or special limits
Emergency services billed multiple times or out of sequence
Labor rates far above event-adjusted benchmarks
Contents claimed without proof of ownership or purchase
Photos with metadata that predate the event or don’t match damage described
Missing permits for structural work or code upgrades
Boilerplate language across unrelated claims driven by the same vendor/PA

Each flag is accompanied by the relevant pages and a concise explanation. For “flag duplicate CT claims receipts AI” scenarios, you can instantly retrieve every page that references the repeated document IDs and amounts across the Connecticut CAT cohort.

3) Policy and Endorsement Alignment

Doc Chat reads your policy stack—base form, endorsements, and declarations—to verify that demand package items align with coverage and conditions. It highlights exclusions that may apply (e.g., wear and tear, prior damage), deductible structures (e.g., hurricane/wind percentage deductibles), and special limits that cap certain categories. It also identifies ambiguous language and provides a citation map to expedite legal review.

4) Benchmarking and Reasonableness Testing

To separate fair post-CAT pricing from abusive markups, Doc Chat compares claimed rates and materials to your references (Xactimate, RSMeans, preferred vendor contracts). It flags outliers and aggregates the total suspected inflation by category—useful for negotiation, EUO preparation, and litigation strategy.

5) Real-Time Q&A, EUO Prep, and Litigation Support

With real-time Q&A, SIU investigators and defense counsel can ask for contradictions, timelines, or gaps seconds before an EUO or mediation. Need all receipts without sales tax? All ALE claims above the lodging cap? All references to pre-existing roof leaks? Doc Chat delivers answers plus source pages, creating a defensible audit trail—a capability emphasized in our client stories and the AI transformation in claims processing article.

Deep Dive: The Fraud Patterns Doc Chat Exposes in CAT Demand Packages

Duplicate and Near-Duplicate Receipts—Within and Across Claims

After major events, unscrupulous actors often reuse receipt images or PDFs. Doc Chat detects duplicates even when document quality varies, or totals and dates are subtly altered. SIU can ask: “Show me all receipts with identical vendor, subtotal, and timestamp” or “Find near-duplicates across the entire hurricane cohort.” For teams working a coastal storm in the Northeast, Doc Chat can quickly “flag duplicate CT claims receipts AI”-style across dozens of Property & Homeowners files and export a cross-claim map with the page citations for each match.

Inflated Labor Rates and Materials

CAT demand packages sometimes embed inflated line items—emergency tarping, crane rentals, or tear-outs at multiples of market rates. Doc Chat compares line-item asks to regional benchmarks, contract rate sheets, or your internal CAT matrices and flags anything that exceeds tolerances. It aggregates variance totals for negotiations or referrals.

Double-Billed Emergency Services and Sequencing Errors

Doc Chat reconstructs the timeline and identifies sequence anomalies—emergency board-up billed twice, mold remediation before water extraction, or inspections billed after the claimed repairs were completed. It also flags mismatches between the vendor’s dates and the policyholder’s ALE timeline or initial adjuster notes.

Contents Claims Without Proof of Ownership

For Coverage C, Doc Chat reconciles claimed items against receipts, statements, photos, and metadata. It highlights items lacking proof, exceeding special limits, or inconsistent with the dwelling characteristics (e.g., claimed high-end equipment not visible in pre-loss photos). It creates a “proof-of-ownership gap list” to streamline follow-ups or EUO questioning.

Policy/Endorsement Conflicts and Special Limits

Demand packages frequently contain items that run afoul of sub-limits or exclusions. Doc Chat ties each questionable line back to the exact policy language and endorsement, presenting SIU with a side-by-side citation trail that’s ready for internal counsel or outside defense.

Vendor Legitimacy and Permits

Doc Chat compiles vendor business names, license numbers, and addresses across the file, highlighting mismatches or missing details. If a structural repair lacks a permit record within the file, Doc Chat flags the gap for follow-up—supporting due diligence with municipal authorities.

Real-World SIU Scenario: Connecticut Wind Event and Reused Receipts

Consider a large wind event in Connecticut generating hundreds of Property & Homeowners claims. SIU notices a cluster of high-dollar roof replacement demands. Doc Chat ingests demand packages containing receipts, repair invoices, Xactimate estimates, SSPOLs, and photos.

In minutes, the system surfaces:

Receipts from “CT Roofing Supply” repeating across four insureds, with identical timestamped totals—but variations in the last digit of the invoice numbers.
Labor rates for tear-off and dry-in consistently 40–60% above the CAT-adjusted benchmark for the county.
A pattern where emergency tarping charges appear twice—once as “emergency response” and again as “temporary stabilization”—across two public adjuster files.
Two files claiming structural work without any corresponding permits in the municipal packet.
Contents claims for expensive tools lacking receipts, coupled with pre-loss photos showing a storage area without the claimed items.

With a single query—“flag duplicate CT claims receipts AI”—Doc Chat produces a consolidated list of repeated receipts with links to every occurrence. SIU now has a defensible, cross-claim evidence set to coordinate EUOs, adjust reserves, and pursue appropriate actions, from reinspection to referral.

From Manual to Machine-Assisted: A Side-by-Side of the SIU Workflow

Manual Process Today

Investigators read line by line, build spreadsheets by hand, and swap between PDFs and policy systems. It can take days to assemble a coherent narrative—time SIU doesn’t have during CAT spikes. Critical cross-claim links are often discovered late, if at all.

With Doc Chat

Within minutes, Doc Chat provides:

A navigable index with all documents classified
A completeness check and missing-item request list
A fraud-flag summary: duplicates, inflation, sequencing errors, coverage conflicts
Coverage alignment with endorsement and exclusion citations
Benchmark variances aggregated for negotiation
Real-time answers to follow-up questions with page citations

The outcome is a faster, more defensible SIU determination—without sacrificing thoroughness. This mirrors the transformation described by carriers in our GAIG webinar replay, where claim file questions that once took days now take moments.

Built for Nuanced, Unwritten SIU Rules

Many SIU techniques live in your top investigators’ heads. They are learned by shadowing, not from a manual. Doc Chat’s advantage is its ability to capture and operationalize these unwritten rules, then apply them consistently at scale. We interview your SIU experts, encode their heuristics, and validate outputs to ensure the system “thinks” like your team. This approach—and why it matters for complex inference across unstructured documents—is explored in Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs.

Security, Compliance, and Defensible Explainability

Doc Chat supports SIU’s regulatory obligations with traceable, page-linked outputs. Our enterprise controls and SOC 2 Type 2 posture align with carrier security requirements.
