# AIA Group: GenAI-enabled medical claims straight-through processing

Medical claims require a human to read every document before payment. AIA instead built a three-tier GenAI stack (OCR intake, report summarization, auto-adjudication plus FWA anomaly detection) so most claims complete without human touch.

Function: Insurance. Patterns: Straight-through processing; Intake redesign. Evidence: mixed.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 2 primary; publication outcomes are verified and reported.

## Before

1. **Customer** — Submit physical forms and paper medical documentation (control: Manual completeness check)
2. **Claims intake staff** — Manually key, validate, and route documents (multilingual, handwritten, non-standard formats) (control: Manual data entry QA)
3. **Claims assessor** — Read every laboratory result, scan, and medical report end-to-end to adjudicate (control: Human adjudication judgment on all claims)
4. **Fraud team** — Manual fraud, waste, and abuse checks (control: Rule-of-thumb manual review)
5. **Payment operations** — Process payment manually (control: Manual payment run)

## After

1. **Customer** — Photograph invoices and documents with a phone (control: Automated instant validation (97% reported accuracy); poor-quality images flagged for retake)
2. **GenAI OCR (in-house)** — Extract key information from non-standard, multilingual, handwritten documents (control: Field-level automated validation)
3. **AI auto-adjudication** — Straight-through process minor claims end-to-end (reported auto-adjudication rate 75%) (control: Auto-adjudication rules and thresholds (not disclosed))
4. **GenAI summarization layer** — Summarize complex medical reports for the assessor on non-routine claims (control: Human assessor decides complex claims; reported review time cut in half)
5. **FWA anomaly model** — Score claims against 20+ risk indicators with encoder-decoder anomaly-adjusted thresholds (control: Model risk thresholds; high-risk claims flagged for investigation)
6. **E-payment rail** — Pay approved claims electronically (99% reported adoption) (control: Automated payment)

## Decision rights

AI holds adjudication authority for minor claims that meet auto-adjudication rules (company-reported 75% auto-adjudication). Complex claims remain with human assessors. The auto-approval threshold and denial authority are not disclosed in any retrieved source; that gap is recorded, not filled.

## Exception path

Poor-quality images are flagged and the customer is prompted to retake photos; complex claims route to human assessors with GenAI summaries; high FWA-risk claims route to investigation.

## Outcomes

- **End-to-end claims straight-through processing rate** (reported): 22% (June 2020) → 73% (December 2024). Company-reported in a single company-authored partner-content article; the source itself attributes the gain to digital adoption and process redesign, with GenAI as one component. Not independently corroborated; AIA's FY2024 annual results corroborate the broader trajectory (92% of service transactions straight-through processed; back-office unit costs -43% from 2020 to 2024) but not this claims-specific figure.
- **Auto-adjudication rate** (reported): 41% → 75%. Company-reported; single source; not independently corroborated.
- **Claim processing time (Korea)** (reported): Two days or more → Less than 25 minutes. Company-reported; statistic type (median, mean, or best case) and volume not disclosed.
- **Assessor review time per complex medical report** (reported): Pre-GenAI review time (absolute value not disclosed) → Cut in half. Relative reduction only; absolute baseline not disclosed; company-reported.

## Executive lesson

The compounding gains came from rebuilding the whole intake-to-payment pipe (OCR, summarization, auto-adjudication, e-payment), not from dropping a model into one step; and the company itself is careful to credit digital adoption and process redesign alongside GenAI, which is the honest way to report these numbers.

## Anti-pattern

Attributing multi-year straight-through processing gains to GenAI alone when the driver is a combined digital adoption, process redesign, and AI program.

## Questions for leaders

- Where does our auto-approval authority actually sit, and would we disclose the threshold as AIA declined to do?
- Which of our intake metrics combine process redesign with AI, and do our disclosures say so?
- What is our equivalent of the Korea 25-minute claim, and is it a median or a best case?
