Overview

Complete implementation of automated Prior Authorization (PA) form filling system for Mandolin healthcare workflow.

Technical Implementation

  • Multi-agent system with specialized extraction and filling agents
  • Vision-based coordinate mapping for flat PDFs
  • Comprehensive validation and missing field reporting

…m filling process is now more robust, handling the correction lifecycle correctly by using separate input and output paths. This resolves file-not-found and incremental save errors. The system now successfully processes multiple patients end-to-end. Also, cleaned up obsolete scripts and updated .gitignore.
…g schema generation. This fixes two core bugs: 1) The FormUnderstandingAgent now correctly extracts visual text labels instead of field IDs by using a more robust prompt. 2) The SchemaRefinementAgent's parsing logic is fixed to correctly handle API responses, preventing mapping failures. The system now demonstrates high accuracy in semantic mapping and data extraction.
…ludes: the final, comprehensive README.md with architecture and setup instructions; a requirements.txt file for dependencies; and an upgrade of all core reasoning agents to use the gemini-2.5-pro model for enhanced accuracy.
…2.5-pro for core reasoning agents to ensure pipeline stability and high accuracy, resolving issues with model name changes.
…appears to have been resolved, and the robust parser is now working correctly. Removing debug statements.
✅ DELIVERABLES COMPLETED:

🏗️ SOURCE CODE:
- MANDOLIN_PA_SYSTEM.py: Multi-agent system for interactive PDFs
- FLAT_PA_SYSTEM.py: Text-anchor system for flat PDFs
- requirements.txt: All dependencies specified
- Modular, production-ready architecture with error handling

🤖 INNOVATIVE FEATURES:
- Dual architecture handles both widget-based AND flat PDFs
- Self-correction validation loop catches AI hallucinations
- Schema-first design works with any unseen form
- Text-anchor positioning eliminates coordinate guessing errors

📊 COMPREHENSIVE TESTING:
- Multiple patients: Adbulla, Akshay, Amy Chen
- Different form types and insurance companies
- Fill rates: 18.0% - 40.7% with detailed missing reports
- 20+ filled PDF examples demonstrating system capabilities

📋 OUTPUT EXAMPLES:
- output_examples/: 8 filled PDFs with processing reports
- Output Data/: Complete extraction data and corrections
- pa_forms/: Additional test results and schema files
- All missing information reports generated

📖 DOCUMENTATION:
- Comprehensive README with installation instructions
- Detailed architectural decisions and thought process
- Performance metrics and limitations clearly stated
- Step-by-step usage instructions for both pipelines
