Case Study / Insurance / Health Claims / AI Automation

Claims documents, read and routed before review begins.

A large insurer was processing high volumes of health claims through manual document review. Mantra Labs designed an AI-assisted claims automation system that used document pre-processing, OCR, NLP, line-item extraction, benefit bucketing, and review workflows to accelerate claims handling and reduce manual operational load.

Claims automation is not a simple document-upload problem.

Health claims processing depends on extracting accurate information from complex documents: invoices, diagnostic reports, hospital bills, pharmacy bills, discharge summaries, policy details, and treatment records.

The system needed to accelerate review without treating claims decisions as a black box.

Document complexity

Claims documents contain inconsistent layouts, scanned images, diagnosis details, treatment descriptions, invoices, line items, and policy references.

Manual review load

Adding more human reviewers was expensive and did not fundamentally improve cycle efficiency.

Line-item accuracy

The system needed to detect and extract individual line items, not just read document-level text.

Benefit mapping

Extracted items needed to be classified into benefit buckets so reviewers could evaluate coverage more efficiently.

A scalable, modular claims automation system for high-volume document processing.

The system was designed to extract text, detect line items, classify information, map items to benefit categories, and support faster reviewer validation.

Document ingestion and pre-processing

Claims documents entered the system as scanned files or images and were prepared for downstream text recognition.

OCR-based text extraction

The system localized text regions and extracted readable text from scanned medical and claims documents.

Line-item extraction

The platform detected individual line items and mapped them into structured outputs for reviewer validation.

NLP-based benefit bucketing

Extracted line items were analyzed and classified into benefit categories for faster review.

Claims review workflow

The automation layer supported review and adjudication rather than removing human judgment.

The workflow moved claims teams from extraction work to adjudication judgment.

01

Ingest

Claim documents are received and prepared for processing.

02

Extract

OCR extracts text from scanned invoices, reports, bills, summaries, and supporting claim documents.

03

Structure

Line items are detected and converted into reviewable outputs.

04

Classify

NLP-assisted logic maps items into benefit buckets and flags inconsistencies.

05

Review

Human reviewers validate outputs and continue adjudication with less repetitive extraction work.

The strongest claims automation systems do not hide judgment. They remove repetitive extraction work so reviewers can focus on the decisions that matter.
Before / After

What changed when the operating model became connected.

Before

Claims reviewers manually extracted information from invoices and reports.

After

OCR and document processing extracted text from scanned claim documents.

Before

Line-item review was slow and repetitive.

After

Line-item detection created structured review outputs.

Before

Benefit mapping depended heavily on manual interpretation.

After

NLP-assisted bucketing helped classify items by benefit category.

Before

Scaling claim volumes required more operational headcount.

After

Reviewers could focus more on validation, exception handling, and adjudication judgment.

The hard part was building intelligence around messy insurance documents.

Claims documents are not standardized forms

They arrive as scans, invoices, discharge notes, reports, and bills with inconsistent formats.

OCR was only the first layer

The system also had to correct distortions, detect line items, classify them, and preserve reviewer control.

Benefit mapping needed domain context

Extracted information had to become meaningful for claim coverage and adjudication.

Reviewers still needed control

The workflow had to accelerate review while keeping human validation in the loop.

Claims intelligence works when automation serves adjudication, not abstraction.

Document intelligence

Medical invoices, reports, hospital bills, pharmacy bills, and discharge summaries could move through structured extraction.

Claims-specific automation

OCR, NLP, line-item extraction, and benefit bucketing were engineered around the claims review workflow.

Reviewer-centered design

The system supported adjudicators while preserving validation and exception handling.

Scalable foundation

The work created a foundation for AI-assisted adjudication workflows without overclaiming fully autonomous decisions.
