NAMASTE Portal Integration with ICD-11

Abstract

The Ayurveda, Siddha, and Unani (ASU) systems of India gained global recognition with the recent update to the International Classification of Diseases, 11th Revision (ICD-11), which incorporates Chapter 26, Module 2 (TM2). This initiative, spanning 2020–2025 and formalized by a donor agreement between the World Health Organization (WHO) and India’s Ministry of Ayush, establishes a standardized language for ASU morbidity. Key outcomes include the successful mapping of 1,941 national Ayush morbidity codes to the new classification and the official release of TM2 on the WHO ICD-11 Browser in February 2025, ensuring international comparability and evidence-based policymaking. India’s implementation roadmap leverages existing digital platforms, including the National Ayush Morbidity and Standardized Terminologies Electronic (NAMASTE) Portal and the Ayush Hospital Management Information System (A-HMIS), powered by a Double Coding system in compliance with the WHO Minimum Data Set requirements. This paper provides a comprehensive analysis of the NAMASTE portal’s architecture, its semantic mapping strategies with ICD-11 TM2, the technical and operational challenges in adoption, and a proposed extended framework incorporating API-based interoperability, FHIR-compliant data exchange, and AI-assisted terminology alignment. The study also presents a comparative analysis of ASU system coverage across Ayurveda, Siddha, and Unani, and charts a future roadmap for full-spectrum integration. This initiative positions India as a global leader in integrating traditional medicine into digital health systems and universal health coverage frameworks..
