How often is the International Classification of Diseases updated?

The International Classification of Diseases (ICD) is a globally recognized standard for diagnostic health information. Updates to the ICD are typically made every ten years, reflecting the evolving understanding of diseases and health conditions, as well as advancements in medical knowledge and practice. This regular long-term update cycle allows for a comprehensive review and the incorporation of new diseases, changes in classification, and other significant modifications that help improve the accuracy and relevance of the coding system.

The ten-year update period provides ample time for researchers and healthcare professionals to analyze new information and trends, supporting the need for systematic revisions. In addition, the World Health Organization (WHO) manages these updates to ensure that they are representative of global health needs.

Shorter timeframes for updates, such as yearly or every five years, would not provide the thorough review necessary to maintain the integrity and reliability of the classification system. These considerations are crucial for maintaining accurate health statistics, which are essential for public health policy and resource allocation.
