Claims processing is where we cut our teeth on enterprise AI. Documents in, decisions out, humans in the loop. It sounds simple. The implementation isn't. Here's what actually works, what breaks, and how to build it properly.
What You Need to Know
- Claims processing is the highest-value starting point for insurance AI. It builds the most reusable infrastructure and delivers measurable ROI within weeks of deployment.
- Three capabilities, built in sequence: document extraction, intelligent triage, and assessment support. Each one accelerates the next.
- The hard part isn't the AI. It's the data pipeline. Getting documents from 47 different formats into a consistent structure is where most of the engineering effort goes.
- Human-in-the-loop is not optional. Every AI-generated assessment requires human review. The goal is faster, more consistent decisions, not autonomous decisions.

The Three Capabilities
Capability 1: Document Extraction
Every claim starts with documents. Policy forms, medical reports, photos, invoices, correspondence, statutory declarations. A single claim might include 5 to 50 documents in different formats.
What the AI does:
- Ingests documents regardless of format (PDF, image, scanned paper, email attachment)
- Extracts structured data: claimant details, dates, amounts, descriptions, policy numbers
- Classifies each document by type and relevance
- Identifies missing information that will be needed downstream
Architecture notes:
The extraction pipeline is the foundation everything else builds on. We use a multi-stage approach:
- OCR and preprocessing. Scanned documents get OCR'd. Images get classified. PDFs get parsed. The goal is clean text with layout information preserved.
- Entity extraction. An LLM extracts structured fields from the text. We use few-shot prompting with examples specific to the insurer's document types.
- Validation. Extracted data gets cross-referenced against the policy management system. Does the policy number exist? Is the claimant's name consistent? Are the dates plausible?
- Confidence scoring. Every extracted field gets a confidence score. Low-confidence extractions get flagged for human review.
What breaks:
Handwritten documents. Poor-quality scans. Documents that mix multiple claims. Forms where the same field appears in different locations across versions. You handle these with specialised preprocessing, not by hoping the model figures it out.
Capability 2: Intelligent Triage
Once you have structured data from the documents, you can route claims intelligently.
What the AI does:
- Assesses claim complexity based on extracted data
- Routes to the appropriate queue: simple (fast-track), standard, complex, or specialist
- Identifies claims that match known patterns (fraud indicators, subrogation opportunities, regulatory triggers)
- Estimates processing time and flags bottlenecks
How we build it:
Triage is a classification problem, but not a simple one. The routing logic combines:
- Rule-based routing for clear-cut cases (claim value under threshold, standard document set, no flags)
- ML classification for nuanced routing (complexity estimation, specialist identification)
- Pattern matching against historical claims for fraud and subrogation signals
The key insight: triage accuracy improves dramatically when you feed it the structured output from document extraction rather than raw documents. This is the compound effect in action. Capability 1 makes capability 2 better.
What breaks:
Over-automating triage. The temptation is to route everything automatically. In practice, about 30-40% of claims are genuinely simple and can be fast-tracked with confidence. The rest need human judgement on routing. The AI's job is to surface the information that makes that judgement faster.
Capability 3: Assessment Support
The highest-value capability, and the one that requires the most care.
What the AI does:
- Retrieves relevant policy sections based on the claim type and circumstances
- Summarises the claim with key decision factors highlighted
- Identifies precedent decisions from the insurer's history
- Generates a draft assessment with reasoning, coverage determination, and recommended actions
- Flags areas of uncertainty or potential dispute
How we build it:
Assessment support is a RAG problem. The AI needs access to:
- Policy documents with the ability to find specific clauses and conditions
- Claims history to identify precedent decisions
- Guidelines and procedures that define the assessment framework
- Regulatory requirements relevant to the claim type
We build a knowledge base from these sources and use retrieval-augmented generation to produce assessments grounded in the insurer's own documentation. Every statement in the assessment includes a citation.
What breaks:
Hallucinated policy references. An AI that confidently cites a clause that doesn't exist is worse than no AI at all. This is why citation and verification are non-negotiable. Every reference in a generated assessment must be traceable to a source document. We build verification into the pipeline, not as a separate step.
The model is the easy part - the pipeline that gets messy real-world documents into a usable state is the real engineering.

Weeks 9-12: Triage
- Build triage classification on top of extraction data
- Deploy routing logic with human override
- Tune routing accuracy based on actual outcomes
- Measure: routing accuracy, queue balance, processing time
Weeks 13-18: Assessment Support

Weeks 19-22: Optimisation
- Refine all three capabilities based on production data
- Build cross-capability analytics (end-to-end processing metrics)
- Identify next capabilities to build on the foundation
What We've Learned
Start with extraction, not assessment. Assessment is the most valuable capability, but it depends on high-quality extraction. Building assessment first means building extraction anyway, just under more pressure and with less room to get it right.
Invest in the feedback loop. The system improves when handlers can flag errors easily. A simple "this extraction is wrong" button with a correction field generates more training signal than any amount of upfront prompt engineering.
Measure handler experience, not just accuracy. A system that's 95% accurate but frustrating to use won't get adopted. A system that's 85% accurate but fits naturally into the handler's workflow will.
Plan for the compound. The infrastructure you build for claims processing should be reusable for fraud detection, underwriting support, and customer communication. If it isn't, you're building a point solution, not a foundation.
