Note: The 11th revision of ICD (ICD-11) was presented at the 72nd World Health Assembly in May 2019 and will come into effect on January 1, 2022. It should be noted that at this time there is no decision to adopt ICD-11 in Canada. As such, the World Health Organization will no longer be updating the international ICD-10 with new content. Therefore, to maintain international comparability, no new content will be added to version 2025 of ICD-10-CA at the third and fourth character codes. For version 2025, updates to ICD-10-CA are permitted at the fifth and sixth characters to add specificity only. If you have any questions or would like to discuss changes to the classifications that would meet your information needs, please email
