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.
Ingest
Claim documents are received and prepared for processing.
Extract
OCR extracts text from scanned invoices, reports, bills, summaries, and supporting claim documents.
Structure
Line items are detected and converted into reviewable outputs.
Classify
NLP-assisted logic maps items into benefit buckets and flags inconsistencies.
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.
What changed when the operating model became connected.
Claims reviewers manually extracted information from invoices and reports.
OCR and document processing extracted text from scanned claim documents.
Line-item review was slow and repetitive.
Line-item detection created structured review outputs.
Benefit mapping depended heavily on manual interpretation.
NLP-assisted bucketing helped classify items by benefit category.
Scaling claim volumes required more operational headcount.
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.
