Insurance Claims Processing: ML-Powered Fraud Detection for National Insurer

A national insurance provider needed faster claims processing with automated fraud detection. We implemented a Fabric data lakehouse with ML-powered fraud detection that processed claims 50% faster and improved fraud catch rate by 25%.

The Challenge

This top-20 US insurance carrier processed 500,000+ claims annually across auto, property, and liability lines. Average claims cycle time was 45 days, with complex claims taking 90+ days. The Special Investigations Unit (SIU) reviewed only 3% of claims for fraud using manual referral rules, missing an estimated $50M in annual fraudulent payouts. Claims adjusters juggled 5+ systems to research a single claim. Customer satisfaction scores were declining due to slow processing times, and the carrier was losing policyholders to competitors with digital-first claims experiences.

Our Solution

Built a unified claims data lakehouse in Microsoft Fabric that consolidated data from the policy administration system, claims management platform, FNOL (First Notice of Loss) intake, third-party data providers (LexisNexis, ISO ClaimSearch), and SIU case management into a single analytical layer.

Developed a machine learning fraud detection model trained on 5 years of claims data with confirmed fraud labels. The model analyzes 60+ features including claim patterns, claimant history, provider networks, geographic risk scores, and text analysis of loss descriptions to score every claim at FNOL.

Created a claims command center dashboard in Power BI showing real-time claim volumes, cycle time metrics by adjuster/unit/region, severity distributions, reserve adequacy, and SIU referral queue with fraud probability scores.

Implemented automated workflow triggers that route high-probability fraud claims directly to SIU, escalate complex claims to senior adjusters, and flag claims requiring subrogation review — reducing manual triage by 40%.

Built adjuster workbench dashboard providing a unified view of all claim information (policy details, loss description, photos, prior claims, fraud score, similar claims) eliminating the need to switch between 5+ systems.

Results

50%Faster Processing

Average claims cycle time reduced from 45 days to 22 days with automated triage and adjuster workbench.

25%Better Fraud Detection

ML model identifies 25% more fraudulent claims than the previous manual referral rules.

$12MFraud Prevented

Additional fraudulent claims caught by the ML model saved $12M in the first year.

40%Less Manual Triage

Automated routing rules handle initial claim triage, freeing adjusters for value-added investigation.

500K+Claims Scored

Every claim receives a real-time fraud probability score at First Notice of Loss.

15 ptsNPS Improvement

Customer satisfaction improved 15 NPS points due to faster, more transparent claims handling.

Implementation Methodology

1

Phase 1 (Weeks 1-4): Data integration. Connected claims, policy, and third-party data sources into Fabric lakehouse with automated quality validation.

2

Phase 2 (Weeks 5-9): Fraud model development. Feature engineering, model training on historical fraud cases, validation with SIU team, and scoring pipeline deployment.

3

Phase 3 (Weeks 10-13): Dashboard and workflow development. Built claims command center, adjuster workbench, SIU dashboard, and automated routing rules.

4

Phase 4 (Weeks 14-16): Deployment and optimization. Trained adjusters and SIU investigators, tuned fraud thresholds, and activated automated workflows.

Frequently Asked Questions

How does the fraud detection model work?
The model analyzes 60+ features at claim intake including claimant history, loss pattern matching, provider network analysis, geographic risk scores, and NLP analysis of loss descriptions. It produces a fraud probability score (0-100) for every claim, with high-scoring claims automatically routed to the Special Investigations Unit.
What is the fraud model false positive rate?
The model is tuned for 92% precision at the high-confidence threshold (score 80+), meaning 92% of claims flagged as high-risk are confirmed fraud. The medium-confidence threshold (score 50-79) is reviewed by adjusters for additional investigation, with 65% confirmed fraud rate.
Can this integrate with our existing claims management system?
Yes, we integrate via APIs with major claims platforms (Guidewire, Duck Creek, Majesco). The fraud score and automated recommendations appear within the adjuster's existing workflow — no new system to learn. The unified workbench dashboard supplements the claims system with analytical context.
