Symphony for Medical Coding: A Next-Generation Agentic System for Scalable and Explainable Medical Coding

ArXi:2603.29709v1 Announce Type: new Medical coding translates free-text clinical documentation into standardized codes drawn from classification systems that contain tens of thousands of entries and are updated annually. It is central to billing, clinical research, and quality reporting, yet remains largely manual, slow, and error-prone. Existing automated approaches on different data. They also provide no explanation for their predictions, limiting trust in safety-critical settings. We
