| Sumario: | Background: Health information management education faces challenges in teaching claims data. Regulations prohibit the use of real, non-deidentified patient claims data within classroom settings. This limits hands-on experience with real-world data formats such as X12 837 institutional (837i) transaction files. Most existing approaches rely on textbook examples or static datasets that have been heavily redacted, which may lack the complexity required to prepare students for roles involving the handling of claims-related data. In this report, the authors describe the design and deployment of an open-source synthetic claims generator and parser designed to democratize access to realistic health care claims data, bridging the gap between theoretical knowledge and practical skills. Methods: A Python-based system was developed that generates realistic X12 formatted 837i claims using real Centers for Medicare & Medicaid Services (CMS) provider and payer databases. The tool features a free browser-based interface, plus local deployment via a command-line interface (CLI) or application programming interface (API) for advanced educational contexts. Finally, a modular two-lecture curriculum framework for integration into existing health information management courses is provided. Results: The browser-based application enables instant access without installation, eliminating technical and privacy barriers. The tool supports generating 1-25 claims per session via the web interface, with the ability to perform batch generation of thousands of claims via CLI/API for analytics projects locally on a user's own machine. All generated files were validated against X12 5010 837i specifications using two independent electronic data interchange validation platforms, confirming zero structural errors and full conformance to industry standards. The framework aligns with American Health Information Management Association core competencies, offering a reproducible and scalable method to support workforce readiness for revenue cycle analyst, medical coding, and health care data analyst roles. Conclusions: By eliminating privacy concerns, financial barriers, and installation complexity, this method offers a scalable, reproducible model for teaching critical electronic data interchange and revenue cycle competencies related to the handling of claims data files. The open-source nature and multiple deployment options of this tool enable adoption across diverse institutional contexts, from community colleges to research universities, and from technical coding to nontechnical users.
