ICD11

ICD11 is the eleventh revision of the International Classification of Diseases, a globally used medical classification published by the World Health Organization. It provides standardized codes and terms for diseases, health conditions, and external causes of injury, intended for health statistics, clinical documentation, reimbursement, and research. It supersedes ICD-10 and serves as the global reference for health data reporting.

Developed by the WHO in collaboration with member states and subject-matter experts, ICD-11 was released in 2018 and later endorsed by the World Health Assembly. Adoption has progressed in many countries since 2022. The system is designed for digital health environments, using a concept-based structure with post-coordination through extension codes, a common ICD-11 Foundation, and a separate ICD-11 MMS for mortality and morbidity statistics.

ICD-11 features a digital-friendly coding framework that enables more precise descriptions of conditions and health problems, including extended information about temporality, severity, and comorbidity through extension codes. Accessed through online tools such as the ICD-11 Browser and coding tools, it is intended to integrate with electronic health records and health information systems.

Uses of ICD-11 include global health surveillance, epidemiology, policy planning, and administrative processes in some jurisdictions. While adoption is voluntary, many health systems are gradually transitioning from ICD-10, which requires software updates, data mapping, and staff training to utilize the new structure.
