Automating Loss Run Report Analysis for Workers Compensation, Commercial Auto, and General Liability & Construction: Reducing Leakage and Improving Reserve Accuracy — A Claims Manager’s Guide

Loss run reports are the backbone of claims oversight, reserve setting, and leakage control. Yet for many Claims Managers, they are also a chronic bottleneck: multi-carrier, multi-year PDFs arrive in inconsistent formats, key fields vary by carrier and line of business, and the sheer volume makes trend detection and red-flag surfacing painfully manual. The result is delayed reserve accuracy, missed subrogation or recovery opportunities, and inconsistent outcomes across desks.

Nomad Data’s Doc Chat changes that equation. Built specifically for insurance documents, Doc Chat delivers AI to process loss run reports at scale, normalizing inconsistent layouts, extracting every field your playbook cares about, and instantly answering plain-English questions. Whether you’re in Workers Compensation, Commercial Auto, or General Liability & Construction, Doc Chat helps Claims Managers automate extraction from carrier loss runs, surface patterns across accident years, and accelerate reserve reviews with a transparent, defensible audit trail.

The Claims Manager’s Reality: Why Loss Runs Are So Hard in Workers Comp, Commercial Auto, and GL & Construction

Despite their operational importance, loss runs remain one of the most inconsistent document types in claims. Carriers label the same concept differently (e.g., “Paid ALAE” vs. “Paid Expense”), fields appear in different orders (or not at all), and historical periods are fragmented across separate attachments. A single insured’s history can span Workers Compensation lost-time claims, Commercial Auto bodily injury and property damage claims, and General Liability construction defect matters within a wrap-up program — each governed by different claim coding standards, reserve practices, and litigation dynamics.

For a Claims Manager, nuances by line of business multiply complexity:

Workers Compensation

WC loss runs often separate paid and reserved indemnity and medical, list nurse case management costs within ALAE, and include ICD/CPT indicators inconsistently. Cumulative trauma and multiple dates of injury complicate sorting by DOI. Litigation and attorney representation flags may be buried in notes fields. You also care deeply about jurisdictional differences (e.g., CA vs. NY), opioid prescribing patterns surfaced from medical reports, and return-to-work status linked to reserve rationale — none of which are reliably presented on every carrier’s loss run. And yet reserve accuracy and the experience modifier impact depend on getting this right, fast.

Commercial Auto

Auto loss runs cross bodily injury and property damage, subrogation and salvage, first-party and third-party coverages. Multi-claimant occurrences, MCS-90 considerations, and overlapping police reports, appraisals, repair estimates, and demand letters create parallel data trails. Litigation indicators, venue, and attorney history are key severity drivers but frequently inconsistently coded. Identifying repeat claimants or providers across fleets and policy years requires connecting dots across divergent formats and claim numbering schemes.

General Liability & Construction

GL & Construction loss runs are further complicated by project-centric structures, OCIP/CCIP wrap-ups, additional insured endorsements, and contractual indemnity. Construction defect claims may reopen years later under different claim numbers. Losses must be tracked by location, subcontractor, and work type while aligning reserves to long-tail exposure. Certificates of Insurance (COIs), endorsements, and contract excerpts matter — but the relevant indicators are often absent from loss runs or obscured by unstructured notes.

How This Work Is Still Handled Manually Today

Most Claims Managers still rely on analysts and adjusters to manually review PDFs, copy/paste fields into spreadsheets, and roll up summaries by policy year, location, or claimant. When your team receives loss runs and historical claims summaries from multiple incumbent and prior carriers, the steps typically look like this:

• Analysts open each PDF, tab by tab, and search for fields like Claim Number, Date of Loss, Line of Business, Cause/Nature, Body Part (WC), Litigated (Y/N), Paid Indemnity, Paid Medical, Paid Expense/ALAE, Case Reserve components, Total Incurred, Subrogation/Salvage, Recovery to Date, Reopened (Y/N), and Status.
• They reconcile inconsistent field names and locate missing values by reading footnotes, headers, or scanning the document for secondary mentions. Negative payment lines and reissued checks must be normalized. Duplicate claim numbers across carriers need to be de-duplicated and mapped to the same occurrence.
• To understand adverse development, they compare month-over-month reserve movements — if that history exists. Where it doesn’t, they consult adjuster notes, FNOL forms, ISO claim reports, police reports, medical summaries, and demand packages to infer why reserves moved — then annotate spreadsheets so managers can trust the roll-up.

Even after this work is done, trend discovery remains laborious. Spotting a cluster of California WC cumulative trauma claims with attorney involvement and opioid prescriptions; identifying Commercial Auto BI claims in a specific venue where demand letters consistently exceed a threshold; or finding GL construction losses with additional insured complications — these insights require more reading, more pivot tables, and more time. The cost is latency in adjusting reserves and leakage from missed recoveries and overlooked outliers.

AI to Process Loss Run Reports: What Claims Managers Actually Need

Generic OCR or RPA can’t deliver the nuance. Loss runs require inference: one carrier’s “Expense” equals another’s “ALAE”; reserve rationales live in side notes; reopened and closed-without-payment statuses are described in free text. As explored in Nomad Data’s perspective on the difference between extraction and inference, document automation isn’t web scraping for PDFs — it’s about teaching machines to read like seasoned claims professionals, reconcile unwritten rules, and then answer questions quickly and defensibly.

That’s exactly what Doc Chat does for AI to process loss run reports across Workers Compensation, Commercial Auto, and GL & Construction.

How Nomad Data’s Doc Chat Automates Loss Run Review End to End

Doc Chat is a suite of purpose-built, AI-powered agents designed for the scale and complexity of insurance. For loss runs, it ingests entire claim file packets and loss run sets — thousands of pages at a time — and produces structured, normalized outputs in minutes. Then it enables real-time Q&A so Claims Managers can get instant answers and citations to the source page.

Here’s how it works in practice for your role:

1) High-volume ingestion and normalization

Doc Chat ingests multi-carrier loss run reports, historical claims summaries, and carrier loss data exported as PDF, Excel, or mixed formats. It normalizes differing field names (e.g., Paid Expense vs. ALAE), standardizes date formats, splits combined incurred into indemnity/medical/expense where possible, and detects reopened claims and duplicate claim numbers. It maps common codes by line of business (e.g., WC Nature/Cause/Body Part taxonomies), and it preserves metadata for defensibility.

2) Cross-document entity resolution

Across carriers and policy years, Doc Chat links occurrences, claimants, insured locations, and vehicle identifiers. For GL & Construction, it associates claims to projects, OCIP/CCIP programs, additional insured endorsements, and subcontractors when referenced in the loss run notes or related attachments. For Auto, it ties subrogation and salvage lines to the originating claim and identifies multi-claimant events.

3) Real-time Q&A and analysis

Ask questions like: “List all WC lost-time claims in CA with attorney involvement and case reserves > $50,000, plus total paid medical to date.” Or: “Show Commercial Auto BI claims with demand letters over $250,000 in [venue], with paid to incurred ratios above 0.75.” Or: “For GL construction defects, highlight claims reopened after 24 months and show reserve movements month by month.” The system returns answers with clickable citations to the exact pages in the loss run where each data point originated, mirroring the transparent auditability used by Great American Insurance Group.

4) Trend surfacing and red-flag detection

Doc Chat surfaces anomalies and risk patterns you define in your playbook: repeated treating providers across WC claims with disproportionate utilization; Commercial Auto BI claims with similar language across demand letters; GL claims where additional insured status or contractual indemnity is likely but not yet pursued; subrogation opportunities not fully recovered; reserve spikes without documented rationale; or clusters by location or subcontractor. It can also flag missing fields (e.g., absent status or incomplete recovery lines) and suggest follow-ups.

5) Outputs you can use immediately

Export normalized loss-level and claim-level datasets to CSV, your BI tools, or your claim system. Create reserve review packets that include a structured summary and the supporting page links. Generate dashboards by line of business, policy period, and venue. The entire process is designed to slot into your reserve rounds, leakage reviews, and SIU referrals without re-engineering your stack.

Automate Extraction from Carrier Loss Runs Without Changing Your Process

Doc Chat is adaptable by design. We train it on your playbooks — your reserve review checklists, SIU red flags, and escalation thresholds — so its extraction, normalization, and alerts reflect how your Claims Managers already work. You won’t need to rewrite your rules; Doc Chat learns them.

Crucially, the system supports both “batch” and “on-demand” modes. For renewal season or acquisitions, run a bulk review of commercial loss histories across carriers and accident years. For daily operations, drag and drop a new set of loss runs or related documents (e.g., FNOL forms, ISO claim reports, medical summaries, or demand letters) and interrogate them immediately. The same capabilities that end medical file review bottlenecks in other parts of claims — as described in The End of Medical File Review Bottlenecks — apply here to loss runs.

Line-of-Business Nuance: How Doc Chat Adapts to Workers Comp, Commercial Auto, and GL & Construction

Workers Compensation

Doc Chat recognizes WC-specific fields like Paid Indemnity, Paid Medical, Vocational Rehab, Nurse Case Management, and splits ALAE appropriately. It aligns Cause/Nature/Body Part codes, flags cumulative trauma, identifies attorney representation, and correlates medical utilization trends (e.g., opioid scripts from medical reports referenced in the loss run). It differentiates medical-only vs. lost-time claims and highlights reserve rationales that do not track with reported RTW status or physician restrictions. When loss runs reference external documents, Doc Chat can ingest those too for fuller context.

Commercial Auto

For Auto, Doc Chat separates BI and PD, recognizes salvage and subrogation flows, and links multi-claimant occurrences. It flags venues with outsized severity and identifies repeat claimants or providers. It correlates police reports, appraisals, repair estimates, and demand letters to the claim where those documents are provided alongside the loss run packet. It spots under-recovered subrogation and highlights reserve adequacy issues based on development patterns and litigation status.

General Liability & Construction

Doc Chat associates losses with projects, OCIP/CCIP wrap-ups, locations, and subcontractors when that information is present in the loss run or related attachments. It surfaces potential additional insured or contractual indemnity issues and flags reopened construction defect claims, mapping reserve and paid development over time. It can spotlight clusters of premises or products claims that share root causes and identify where endorsements or COIs referenced outside the loss run may drive coverage complexity.

The Business Impact for Claims Managers: Time, Cost, and Reserve Accuracy

Automating loss run analysis has a direct, measurable impact across your Claims organization:

• Time savings: Reviews that once required days of manual reading across carriers compress into minutes. Claims Managers and Reserve Specialists reach decisions faster and can review more files per cycle without adding headcount.
• Cost reduction: Less overtime and fewer external reviews for standard analyses; leakage drops as subrogation opportunities and reserve discrepancies are caught earlier.
• Accuracy and consistency: Normalized fields, standardized taxonomy, and playbook-aligned alerts produce consistent outcomes across desks, improving your reserve adequacy and audit readiness.
• Scalability: Surge volumes at renewal, M&A diligence, or program conversions are handled by the system instantly; your team focuses on exceptions and strategy rather than data wrangling.

These gains mirror the broader results carriers see when they reimagine claims with AI. In one account, tasks that took days were reduced to moments, with page-level explainability increasing trust — as described in our Great American Insurance Group case study. And as we noted in Reimagining Claims Processing Through AI Transformation, focusing human talent on judgment instead of rote review not only accelerates cycle times but also reduces burnout and turnover.

From Manual to Automated: A Before-and-After Snapshot

Before: Your team receives a 5-year, multi-carrier loss run set for a national contractor with programs spanning Workers Comp, Commercial Auto, and GL & Construction. Analysts manually key fields into spreadsheets, fix inconsistent columns, email adjusters for missing reserve breakdowns, and spend hours reconciling duplicates and reopeners. Reserve rounds occur with incomplete visibility into late-stage development, subrogation gaps, and litigation-driven severity drivers. SIU referrals are ad hoc.

After: The same packet is dropped into Doc Chat. Within minutes, you have a normalized dataset across all lines, linked occurrences and claimants, reserve movement summaries, and red-flag lists by your playbook. You ask, “Which WC claims show paid medical > 2x peer median with opioid indicators?” and receive answers with citations. You export a reserve review packet that includes source-page links for audit, and you hand SIU a prioritized list of questionable patterns across venues and providers. Reserve adjustments and recovery actions occur in the same meeting, not two cycles later.

Two Workflows Where Claims Managers See Immediate ROI

1) Reserve Round Acceleration

Doc Chat prepares pre-read reserve packets from the latest loss runs, aggregating reserve movements, litigation status changes, recovery updates, and exposure notes into a consistent format. Each line item links to source pages. The result: reserve rounds that start at 95% context, not 0%, with more time for decision-making and less time rebuilding the story.

2) Leakage and SIU Triage

By encoding your red-flag indicators, Doc Chat automatically surfaces suspicious patterns: copy-paste language across demand letters; claimants appearing across multiple policies; WC utilization spikes out of pattern; GL additional insured situations with no recovery action. SIU receives a ranked queue with evidence links — not just a hunch.

Bulk Review of Commercial Loss Histories: Pre-Renewal, Rollovers, and M&A

When program changes or acquisitions demand speed, Doc Chat handles bulk review of commercial loss histories reliably. Ingest decades of carrier loss runs, normalize across lines of business, and produce executive-ready summaries of severity drivers, development hot spots, subrogation gaps, and venue risk. Claims Managers and Loss Control Analysts partner on mitigation plans using the same evidence-base, ensuring reserves and strategy align with reality.

We recommend keeping humans in the loop for determinations, just as we outline in Reimagining Claims Processing Through AI Transformation. Think of Doc Chat as your fastest, most consistent junior analyst who never gets tired.

Technical Fit and Integration

Doc Chat starts working immediately with a simple drag-and-drop interface for loss run reports, historical claims summaries, and carrier loss data. As you scale, we can integrate with your claim platforms and data warehouse through APIs to automate ingestion and delivery of structured outputs. Many teams begin with on-demand analysis for urgent cycles (renewals, reserve rounds) and graduate to steady-state automation for monthly loss run refreshes and leakage reviews.

A Quick Guide to Success: From Pilot to Production in 1–2 Weeks

Our white glove process is straightforward:

• Discovery: We meet with your Claims Managers and analysts to capture your loss run field priorities, reserve review playbook, and SIU criteria by line of business.
• Configuration: We map common carrier formats, set normalization rules, and encode your red flags. We define your preferred output schemas (spreadsheets, dashboard feeds, reserve packets).
• Pilot: You upload real loss run packets. We validate extraction quality together, tune edge cases, and confirm that Q&A answers align with your expectations — with citations.
• Go live: Your team begins day-to-day use. We remain a hands-on partner, expanding carriers and playbooks and measuring impact on reserve accuracy and leakage.

Because Doc Chat is purpose-built for insurance documents, most pilots convert to production quickly — often within days — and your team retains continuity of process throughout.

Frequently Requested Questions from Claims Managers

Can Doc Chat reconcile inconsistent ALAE reporting across carriers?

Yes. We normalize “Paid Expense,” “Paid ALAE,” and related terms into a consistent schema aligned to your definitions. Where ambiguity exists, Doc Chat surfaces it for review with the original citation, so your team can decide and standardize going forward.

Does it handle reopened claims, duplicate claim numbers, and cross-carrier occurrences?

Yes. Doc Chat detects reopeners and duplicates, links multi-claimant occurrences (especially common in Auto), and reconciles cross-carrier references to the same incident when loss run notes or identifiers make that possible.

Can we combine loss runs with FNOL forms, ISO claim reports, demand letters, and medical summaries?

Absolutely. Doc Chat is designed to ingest whole claim file packets alongside loss runs. This context often explains reserve movements and reveals recovery opportunities, and the citations help your team verify quickly.

How does it help with reserve adequacy?

By surfacing development patterns, outliers by venue or provider, and reserve changes without documented rationale, Doc Chat gives Claims Managers the evidence they need to adjust reserves sooner and more consistently — reducing surprises and supporting better financial forecasting.

Measuring Impact: What to Track

To quantify the value of automating loss run analysis, Claims Managers typically track:

• Time to produce reserve packets and complete reserve rounds
• Percentage of loss runs processed per week/month (capacity) without additional FTE
• Leakage reduction from earlier subrogation recovery, SIU referrals, and reserve corrections
• Consistency of reserve adequacy by line of business and venue
• Cycle time from loss run receipt to action items (reserve change, SIU referral, recovery notice)

As documented across our client base, shifting from days of manual reading to minutes of automated analysis improves both speed and quality, while improving morale as professionals focus on investigative work instead of data entry.
