This bulletin confirms an ICD-10-CA code title change for B04 to Mpox [monkeypox]. This change will take effect April 1, 2025. There is no change to the classification of mpox. It is still classified to B04 Mpox [monkeypox] per previous direction.

In response to client feedback, we continue to streamline and modernize the CCS. This work includes retiring coding standards when coding direction is found in the classification (ICD-10-CA or Canadian Classification of ºìÁì½í¹Ï±¨ Interventions [CCI]) and removing content that does not provide coding direction (e.g., educational, clinical and legislative content). It also includes removing optional coding; consolidating directive statements, notes and exception notes; retiring or refreshing examples; writing in clearer language; and restructuring the content. For information about the status of the CCS changes, refer to Canadian Coding Standards Proposed Changes (XLSX). The next posting will occur in January 2025.

This bulletin identifies that ºìÁì½í¹Ï±¨is embarking upon a multi-year roadmap to modernize acute and ambulatory care and hospital data. Highlights from this bulletin include postponement of new versions of CCI and the CCS until 2027–2028, and the release of the 2025–2026 ICD-10-CA/CCI Classification Tables in October 2024. To align with the World ºìÁì½í¹Ï±¨ Organization (WHO), which froze ICD-10 at the 2019 version, ICD-10-CA will be frozen at version 2022.

The updated eQuery Questions: Archived and Revised, and Coding Direction in eQuery Only is now available. It lists archived coding questions and coding questions that were closed and posted or that were posted only for revised responses, or for which direction was provided in eQuery between April 1, 2018, and September 30, 2024.

Changes to the next version of CCI (v2027)

Updates to the status of change requests for the next version of CCI are now available. This document provides a full list of requests for enhancing CCI, the status of the request and the decision rationale. Approved requests will appear in the next version of CCI. The next edition is scheduled for release in January 2025.

The ºìÁì½í¹Ï±¨SNOMED CT CA to ICD-10-CA reference set and the Pan-Canadian ºìÁì½í¹Ï±¨ Concern Value Set (PHCVS) will be updated quarterly to align with the release of SNOMED CT CA. The current version aligns with the August 30 release of SNOMED CT CA and was published on November 6. These maps can be found on CIHI’s health information software vendors web page and in .

The Classifications and Terminologies team is actively assessing Canada’s readiness for ICD-11. Here are some quick updates on ICD-11 projects:

• Pan-Canadian ICD-11 Implementation Task Force: We are in the process of identifying jurisdictional representatives to join the task force. Once these representatives are confirmed, a meeting will be scheduled.
• French translation: We are collaborating with the WHO and the French WHO Family of International Classifications (WHO-FIC) Collaborating Centre to validate the French translation of the ICD-11 MMS (Mortality and Morbidity Statistics). This process will ensure that the French terms used are accurate and appropriate.
• Impact assessment activities: We are actively conducting impact assessment activities related to ICD-11. Our efforts are focused on determining the need for a country-specific version; developing crosswalks to facilitate transition; assessing adoption impacts on federal and jurisdictional data systems and CIHI’s health indicators; and evaluating the clinical utility of ICD-11 across various health care settings, including primary health care and mental health.
