Claims Triage in 90 Seconds: The AI Architecture Behind Instant Insurance Decisions

Insurance claims follow a heavy-tailed distribution: a small percentage of complex, high-value, or disputed claims require significant adjuster expertise, while the majority are straightforward. A minor auto collision where liability is clear, damage is documented, and the policyholder has a clean history is not a complex judgment call — it is a data-matching exercise. The problem is that traditional claims systems route everything through the same queue. A simple fender-bender sits behind a disputed commercial property claim for days because both land in the same workflow. Intelligent triage — separating claims into fast-track automated, assisted review, and full investigation streams at intake — is the foundation of AI-powered claims operations. Properly calibrated, 55–65% of P&C claims qualify for straight-through processing without adjuster involvement.

Claims arrive as a heterogeneous mix: mobile app submissions with photos, email attachments with PDFs, faxed repair estimates, police reports, and medical records from multiple providers. The first AI layer is document ingestion and information extraction — parsing whatever format arrives and extracting the structured fields the claims system needs: date of loss, coverage type, claimed amount, involved parties, and supporting documentation. Modern multimodal models handle this well: a photo of a damaged vehicle feeds a computer vision model that estimates repair cost categories; a medical record feeds an NLP pipeline that extracts diagnosis codes, treatment dates, and provider identifiers. The key engineering challenge is confidence scoring — the system must know when its extraction is reliable enough to proceed automatically and when to flag for human verification.

Fraud costs the insurance industry approximately $80 billion annually in the US alone, with organised fraud rings particularly active in auto, workers' compensation, and healthcare lines. AI fraud scoring at intake — before a claim enters the processing queue — prevents fraud from consuming adjuster time and inflating settlements. Effective fraud models use a combination of features: claim characteristics (frequency, timing relative to policy inception, claimed amount distribution), network features (connections between claimants, providers, and repair shops in historical fraud cases), and behavioural features (metadata from submission — device fingerprinting, IP geolocation, submission timing patterns). Graph neural networks that model the network of relationships between claims, providers, and policyholders are particularly effective at detecting organised fraud rings, which have distinctive network signatures even when individual claim characteristics appear legitimate.

A significant portion of claims processing time is consumed by coverage verification: confirming that the loss is covered under the policy, calculating applicable deductibles and sublimits, and determining whether exclusions apply. This is fundamentally a question-answering task over structured policy documents — exactly the problem retrieval-augmented generation (RAG) systems handle well. Production deployments use a policy RAG system: the claim characteristics are used to query the policy document store, retrieve the relevant coverage sections, and generate a structured coverage determination with citations to specific policy language. For standard claims, this replaces a 45-minute adjuster review with a 4-second automated determination. Liability determination in multi-party auto claims uses a separate model trained on accident reconstruction data and state-specific comparative negligence rules.

For auto physical damage claims, AI-powered damage assessment from photos has reached the point where field inspection is no longer necessary for the majority of personal auto claims. Computer vision models estimate repair costs by identifying damaged components, classifying damage severity, and pricing repairs using regional labour rate data and parts pricing databases. The models are calibrated against actual repair invoices from thousands of shops — they learn the relationship between visible damage characteristics and final repair costs at a regional level. For medical claims, AI settlement models incorporate diagnosis codes, treatment protocols, regional medical cost data, and comparable settlement history. The critical safety layer is settlement authority limits: AI-calculated settlements above a threshold automatically route to adjuster review regardless of claim complexity score.

Straight-through processing targets should not approach 100% — that would mean the system is processing claims it lacks confidence to handle correctly. The 6% that require human expertise fall into predictable categories: large losses above material thresholds ($50K+ for most carriers), disputed liability where statements conflict, coverage questions requiring legal interpretation, catastrophe claims where standard damage models do not apply, and claims from policyholders who specifically request human interaction. The AI system's job in these cases is not to make the decision but to prepare the adjuster: assembling the claim file, extracting key facts, scoring complexity, and routing to the adjuster with appropriate expertise for the claim type. Adjusters handling AI-prepared files resolve claims 40% faster than those working from raw incoming documents.
