The CAT reality for field adjusters across Property & Homeowners, Commercial Auto, and Specialty Lines & Marine

Field adjusters in catastrophe events work at the intersection of speed, precision, and empathy. The challenge intensifies as documentation volumes surge and claim complexity escalates. Each line of business brings unique nuances:

Property & Homeowners: Wind vs. water, roof vs. interior, and endorsement landmines

After a hurricane or windstorm, a single homeowners claim can include dozens of PDFs and hundreds of images: FNOL forms, policy declarations, endorsements, mitigation invoices, contractor estimates, receipts, adjuster notes, and annotated inspection photos. Determining what’s covered hinges on details like anti-concurrent causation clauses, named storm deductibles, roof surfacing endorsements, water/seepage exclusions, and ALE (Additional Living Expense) sublimits. Adjusters must connect policy language with observations in property assessments, loss statements, roof and attic photos, and contractor damage appraisals, then justify determinations with page‑level support.

Commercial Auto: Hail, flood, debris impact, total loss math, and business interruption

Large hail events and urban floods generate hundreds of commercial auto claims overnight—across mixed fleets, vehicle upfits, and varying coverage limits. Adjusters reconcile police reports, weather verification, repair estimates, salvage bids, telematics snapshots, driver statements, and ISO claim reports. They need quick clarity on comprehensive vs. collision applicability, prior damage, shop rate reasonableness, glass coverage, diminished value, potential subrogation, and whether a vehicle meets total loss thresholds given ACV and salvage returns.

Specialty Lines & Marine: Complex causation across docks, vessels, cargo, and inland transit

Storm surge and port closures complicate marine and cargo claims. Field adjusters navigate surveyor reports, bills of lading, packing lists, moisture readings, port authority notices, P&I club correspondence, USCG incident reports, and specialized endorsements (e.g., F.P.A., particular average clauses). Causation can span multiple legs of transport and carriers. Linking policy clauses to evidence in images (hull, engine, bilge, cargo stowage) and time-stamped logs becomes decisive.

How the process is handled manually today

Traditionally, surge events force adjusters and desk examiners into triage mode. Claim files arrive incomplete, out of order, or in formats that resist quick scanning. Adjusters manually:

• Open, read, and tag each file: FNOL, policy PDFs, endorsements, property assessments, repair estimates, invoices, catastrophe model footprints, expert reports, and photo folders.
• Build ad‑hoc timelines of events, weather, and inspections, cross‑checking dates and locations with policy inception/expiration and deductibles.
• Hunt through emails and portals for missing documentation: contractor licenses, permits, prior loss run reports, ISO claim reports, underwriting notes, and photos that actually show the damaged area.
• Extract data into spreadsheets or claim systems by hand: coverage limits, sublimits, deductibles, exclusions, part costs, labor hours, salvage values, and reserve recommendations.
• Draft summaries and rationales for coverage and causation, citing page references—then redo them whenever new documents arrive.

Under surge conditions, this manual workflow collapses under its own weight. Adjusters face backlogs, overtime, and rising loss adjustment expense. Fatigue invites errors, missed endorsements, mis‑applied deductibles, and inconsistent outcomes. As Nomad explains in “Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs,” genuine document intelligence requires inference across scattered clues—not just keyword search.

Why legacy tools break during CAT surges

Keyword search, rigid templates, and generic OCR buckle under CAT conditions because the information you need often isn’t written in one place. It’s implied across policy language, endorsements, estimates, and visual evidence. A wind-driven rain exclusion might matter only if an opening in a roof is documented; a named storm deductible may trigger only for certain time windows or geographic footprints; “flood” vs. “storm surge” can change everything in coastal claims. Legacy tools weren’t built to reconcile these nuances at scale or to surface page‑level support on demand.

Nomad’s experience with complex insurance documents, highlighted in “Reimagining Claims Processing Through AI Transformation” and the GAIG case study “Great American Insurance Group Accelerates Complex Claims with AI,” shows that success hinges on reading like a claims expert—every page, every photo, every endorsement—and answering natural‑language questions with citations to the source.

Automate surge event documentation review with Doc Chat

Doc Chat ingests entire claim files—thousands of pages at a time—across PDFs, Office documents, emails, and images. It extracts and cross‑checks policy language, endorsements, declarations, coverage limits, deductibles, cause-of-loss indicators, estimates, invoices, and more. It then enables real‑time Q&A so a field adjuster can ask questions like “List all roof-related exclusions and the applicable deductible for named storms” or “Show inspection photos that evidence pre‑loss wear.” Answers come back with page or photo references so you can click to verify.

Unlike generic tools, Doc Chat is trained on your playbooks and standards—the Nomad Process—so outputs reflect how your Property & Homeowners, Commercial Auto, and Specialty & Marine teams assess coverage, causation, and damages. During surges, this personalized intelligence ensures consistent, defensible decisions at volume.

Volume and speed purpose-built for CAT

CAT operations demand extreme throughput. As Nomad outlines in “The End of Medical File Review Bottlenecks,” Doc Chat processes approximately 250,000 pages per minute and converts multi‑week reviews into minutes. In claims environments highlighted in the GAIG story, adjusters moved from days of scrolling to seconds of answers—with citations for instant verification.

Photo‑aware decision support

Inspection photos are first‑class citizens, not attachments to ignore. Doc Chat can catalog, label, and connect photos to narrative evidence, estimates, and policy provisions. Ask: “Which photos depict roof decking exposure?” or “Show pre‑loss condition indicators called out by the contractor.” Link those back to the exact estimate line items and policy wording that govern coverage and pricing.

From scattered inputs to a single source of truth

Doc Chat assembles timelines, normalizes estimates, and maps references across policies, endorsements, and job notes. It flags mismatches—like a hail date outside the policy period, a named-storm deductible applied to a non‑named event, or an invoice amount that conflicts with the submitted loss statement. For specialty cargo, it can align voyage legs, weather interruptions, and damage notations across survey reports and bills of lading to support subrogation or partial coverage determinations.

Field‑ready prompts for surge scenarios

• “Summarize this claim’s coverage triggers, limits, sublimits, and deductibles; cite policy and endorsement pages.”
• “List evidence supporting wind vs. flood causation; include photo references.”
• “Extract all contractor estimate line items for roof, gutters, siding, and interior; compare against policy limits.”
• “Identify potential pre‑existing damage and reference any prior losses (loss run reports, ISO claim reports).”
• “For this fleet hail claim, compute total loss candidates based on ACV and salvage assumptions; list supporting documents.”
• “For the cargo claim, reconcile surveyor findings with bills of lading and packing lists; highlight policy clauses affecting partial loss recovery.”

AI to process CAT claim files: an end‑to‑end flow for field adjusters

Doc Chat streamlines the full CAT lifecycle while keeping adjusters in the driver’s seat.

1) Intake and completeness check

Drag and drop a file bundle or pass a claim from your intake system. Doc Chat automatically classifies documents—FNOL, policy jacket, declarations, endorsements, property assessments, damage appraisals, repair estimates, police reports, marine surveys, invoices, and photos—then flags what’s missing based on line‑of‑business rules and your playbooks. It can suggest requests: “Need roof measurements or engineering report,” “Missing driver statement,” “Request USCG incident number,” or “Obtain packing list for container ABC123.”

2) Coverage and trigger analysis

Doc Chat extracts coverage terms, endorsements, deductibles (wind/hail, named storm, flood), sublimits (ALE, debris removal), valuation method (ACV vs. RCV), and exclusions (water seepage, wear and tear, faulty workmanship). It aligns these with the asserted cause of loss, dates, and location data. For auto, it confirms comp/collision applicability and glass endorsements; for marine, it checks clauses like “institute cargo clauses,” perils of the sea, and delay exclusions.

3) Evidence consolidation and causation

It summarizes key facts from inspection photos, engineer notes, and estimates, building a coherent narrative: the opening that allowed wind‑driven rain; the hail impact pattern consistent with the storm footprint; or cargo wetting consistent with ingress at port. Every assertion is linked to the underlying page or image so you can validate instantly.

4) Damages and estimate reconciliation

Doc Chat extracts line items from contractor estimates and appraisals, checks unit costs, flags duplicate entries, and highlights scope mismatches. It can compare estimates against policy limits and sublimits, compute deductibles, and make reserve suggestions bound by your rules. For auto, it cross‑checks with salvage bids and repair times; for marine, it isolates particular average items and relates them to covered perils.

5) Fraud and anomaly detection

Using patterns observed across clients and encoded rules, Doc Chat flags red flags—reused photos, repeated language across unrelated claims, mismatched timestamps, or invoices that don’t reconcile. It recommends investigatory steps: verify contractor credentials, confirm event weather at the address, or validate serial numbers against prior losses.

6) Settlement, subrogation, and reinsurance reporting

Finally, Doc Chat produces a structured summary with page‑level citations suitable for supervisor review, reinsurer reporting, or legal referral. It can prepare subrogation packages (e.g., third‑party contractor negligence, shipper liability) by consolidating proof points and policy provisions that support recovery.

The potential business impact: speed, cost, accuracy, and morale

The impact of automated surge event documentation review is both immediate and lasting:

• Time savings: Carriers see entire claim file reviews move from days to minutes. As documented in Nomad’s case studies, a 10,000–15,000 page file can be summarized in under 30–90 seconds, and batch throughput reaches hundreds of thousands of pages per minute. Field adjusters and desk examiners reclaim hours per file for investigation and insured communication.
• Cost reduction: Less overtime, fewer external experts for routine reviews, and reduced loss adjustment expense. Automation scales instantly during surge without adding headcount.
• Accuracy and consistency: The AI reads every page with the same rigor—no fatigue, no skipped endorsements. Page‑level citations make decisions defensible to supervisors, reinsurers, and regulators.
• Reduced leakage and better fraud control: Hidden exclusions, mismatched deductibles, and duplicate invoices are surfaced systematically, as described in “Reimagining Claims Processing Through AI Transformation.”
• Happier teams, lower turnover: Adjusters spend less time on tedious data entry and more time applying judgment, improving morale and retention—an outcome also highlighted in “AI’s Untapped Goldmine: Automating Data Entry.”

In the GAIG example, adjusters reported that Nomad finds needed facts instantly and links them back to exact source pages, collapsing multi‑day hunts into moments and enabling faster, higher‑quality determinations—critical during CAT spikes.

What “good” looks like during a CAT surge: three quick vignettes

1) Homeowners wind and water loss after a named storm

A field adjuster uploads a claim bundle containing FNOL, policy and endorsements, mitigation invoices, an engineer’s report, contractor estimate, and 180 inspection photos. Doc Chat returns:

• A coverage map with named-storm deductible, wind-driven rain exclusion, ALE sublimit, and debris removal sublimit—each cited to page and clause.
• A causation summary linking the engineer’s notes and photos to roof uplift and water intrusion through a storm‑created opening.
• Estimate reconciliation with potential double counts and non‑covered line items flagged.
• An adjuster‑ready summary and reserve recommendation that align with internal playbooks.

Outcome: The adjuster speaks with the insured the same day with a defensible position, reduces rework, and documents rationale for leadership review.

2) Hail event impacting a commercial fleet

Hundreds of vehicle claims arrive from a single client. Doc Chat groups by VIN, normalizes repair estimates, and highlights likely total losses (ACV vs. repair cost vs. salvage). It flags identical photo reuse across multiple VINs and detects an estimate pattern inconsistent with the event date. The adjuster finalizes accurate reserves and prioritizes investigations for anomalies.

3) Marine cargo wetting during port closure

Surveyor reports, bills of lading, packing lists, and moisture readings are ingested. Doc Chat consolidates timelines, links stowage photos to reported ingress points, reconciles clauses governing partial loss, and drafts a subrogation package against a negligent third party—all with source links. The adjuster accelerates recovery, not just adjudication.

Frequently used documents and forms Doc Chat handles in CAT

Doc Chat is tuned for the documents CAT adjusters see daily across lines of business:

• FNOL forms (including ACORD Property Loss Notice and Vehicle Loss Notice)
• Policy jackets, declarations, endorsements (wind/hail, named storm, water exclusions, ALE)
• Property assessments, damage appraisals, and contractor estimates
• Inspection photos, engineering reports, and mitigation invoices
• Police reports and ISO claim reports (Commercial Auto)
• Marine surveyor reports, bills of lading, packing lists, and port authority notices
• Loss statements, loss run reports, and reserve updates
• Correspondence, demand letters, and salvage bids

“Automate surge event documentation review”: what field adjusters actually experience

Adjusters tell us that the first hour with Doc Chat feels like getting a second brain. Instead of starting at page one, they start by asking pointed questions and verifying answers with one click to the source. The workflow flips from “read everything, then decide” to “decide what you need to know, then confirm instantly.” That’s the essence of automation in a surge: fewer bottlenecks, more confident decisions.

In GAIG’s experience, described in “Reimagining Insurance Claims Management,” adjusters moved from days of manual searching across thousand‑page medical and legal packages to seconds, with every answer linked to a source page. The same principle applies to CAT claim bundles of policies, estimates, and photos.

Best tools for handling high-volume CAT claims: choosing AI that fits the field

When leaders evaluate best tools for handling high‑volume CAT claims, three criteria separate winners from the rest:

• Depth over keywords: Can it infer coverage and causation across scattered references and inconsistent formats?
• Explainability at source: Do answers link to specific pages and photos for instant verification and audit defense?
• Customization to your playbooks: Will it produce outputs the way your Property, Auto, and Marine teams work—and evolve with your standards?

Doc Chat checks all three. It’s built to read like a claims expert and to institutionalize your best adjusters’ judgment at scale, a theme explored in “Beyond Extraction.”

Operational safeguards: security, compliance, and audit readiness

CAT claims often attract regulator and reinsurer scrutiny. Doc Chat provides:

• Page‑level citations for every answer and summary element.
• Time‑stamped audit trails of questions, answers, and document versions.
• Role‑based access controls and enterprise security, including SOC 2 Type 2 processes.
• Configurable retention and export options to align with your compliance policies.

This rigor shortens audit cycles and strengthens your defense against leakage and disputes.

Implementation in 1–2 weeks: a field‑first rollout

Field adjusters can start immediately using drag‑and‑drop uploads to experience instant value—no integrations required. As usage scales, Nomad partners with your IT and claims operations teams to connect Doc Chat with your intake, claim, and document management systems—typically in 1–2 weeks, thanks to modern APIs and Nomad’s white‑glove approach. We onboard to your guidelines, QA against your gold‑standard files, and tune prompts to your line‑of‑business nuances.

CAT‑season readiness: a practical checklist

• Identify top document types per LOB (e.g., endorsements for named storm, roof assessments, surveyor reports).
• Codify surge playbooks: coverage triggers, deductibles, sublimits, valuation methods.
• Set “completeness checks” for FNOL to speed early requests (photos required, estimate standards, surveyor scope).
• Define standard outputs: coverage summary, causation evidence set, estimate reconciliation, reserve rationale.
• Pilot with last season’s CAT files; validate against known answers; iterate.
• Integrate with claim systems; enable bulk ingestion for surge volumes.
• Train teams on natural‑language prompts and verification with page citations.
