Classifications and Terminologies highlights

New: ICD-10-CA and CCI enhancement requests for v2021

Stakeholders such as clinical experts, eQuery users and CIHI’s program areas all submit requests to modify the ICD-10-CA and CCI classification systems.i The Classifications and Terminologies team also makes modifications to ICD-10-CA based upon World Health Organization (WHO) changes to the base ICD-10.

Classification specialists review each request in compliance with predetermined criteria outlined in the Public Submission Guidelines for Updating ICD-10-CA and CCI. They determine if the change requested will proceed.

CIHI has posted a document outlining the requests for change received as of February 5, 2019, along with the status of the review process and/or decision and rationale for enhancement requests. This document will be updated on a quarterly basis.

Approved requests will appear in v2021 of the ICD-10-CA and CCI.

Reminder: Criteria for Classifications eQuery coding question service

All questions submitted to the Classifications eQuery coding question service must meet 1 or more of the criteria listed in the bulletin and job aid, located on our Codes and Classifications web page. As a reminder, we will only answer questions that meet the criteria and will return all others with a rationale for non-response. Should your question be returned, you will be invited to submit a new coding question on the same topic.

You may also refer to the iCODE Strategy and the webinar Optimizing Your eQuery Coding Questions. These products can help you resolve challenging coding questions and, when needed, assist you with creating and submitting a question that meets the criteria.


The alpha-version of the Canadian Emergency Department Diagnosis Shortlist (CED-DxS) common terms mapped to the Systematized Nomenclature of Medicine — Clinical Terms (SNOMED CT) has been updated. This updated version reflects the changes in v6.0 of CED-DxS where new content for cannabis-related harms was added. The alpha-version has also been enhanced to reflect changes made to the Canadian edition of SNOMED CT, which was released on April 30, 2019. Look for this in CIHI’s eStore in June. Any feedback on the alpha-version can be sent to nacrspicklists@cihi.ca.


In the Spotlight series

On June 25, 2019, the Classifications and Terminologies team hosted an In the Spotlight webinar titled Contributing to Quality Data: A Coder’s Role. It focused on the input, output, outcomes and impact of data quality and the coding specialist’s role in that cycle. The webinar was recorded in English and French. The links will be posted in the In the Spotlight section on the Codes and Classifications web page after July 19, 2019.

Previous webinars in this series include

ICD-11 series

On June 4, 2019, the Classifications and Terminologies team hosted a webinar about the International Classification of Diseases 11th Revision (ICD-11) titled Introduction to ICD-11 — Part 2. The recording is available on the Codes and Classifications web page.

An earlier webinar in this series is Introduction to ICD-11 — Part 1. Please note the title of the webinar was previously ICD-11 Mortality and Morbidity Statistics (MMS) — Part 1. While the webinar’s title has changed, the content has not.

For future sessions

These webinars are not available through CIHI’s Learning Centre, nor do they do require registration. Webinar details such as topic, date and instructions for access will be circulated via email. If you would like to be informed about future webinars, please email classifications@cihi.ca.


On May 25, 2019, the World Health Assembly approved a resolution to adopt ICD-11. This means that ICD-11 will come into effect as the new international standard on January 1, 2022.

However, it should be noted that a decision about adoption for implementation in Canada has not yet been made. CIHI will continue its work with stakeholders to assess the implications of implementation for morbidity uses.

A number of initiatives are planned for 2019–2020, including the following:

  • Assessing ICD-11 for the use of Canadian morbidity data to ensure international comparability, targeting Canada-specific codes and codes utilized in CIHI health indicator reporting
  • Familiarizing people with ICD-11 by delivering a series of 4 or 5 webinars. 2 of the planned webinars, Part 1 and Part 2 of An Introduction to ICD-11, are now available. Recorded versions can be accessed on the Codes and Classifications web page.
  • Conducting an impact analysis of ICD-11 on CIHI products and systems, including the impact to external stakeholders.
  • Continuing to collaborate with the WHO by participating in activities coordinated through various WHO committees (the Classification and Statistics Advisory Committee, the Morbidity Reference Group, the Informatics and Terminology Committee and the Education & Implementation Committee).

Updates on these ICD-11 initiatives and new ICD-11 activities will be shared throughout 2019.

Coding questions

New: Translation of English coding questions into French

Beginning with coding questions related to fiscal year 2019–2020 data, English coding questions viewable in the eQuery database will be translated into French.

Updated coding questions

On occasion, a coding question is re-opened to revise the answer. This is done when an error is identified, when there is new information or when there is a change in direction and there is value in revising the answer.

The following coding questions have been revised and updated since December 2018. Log in to eQuery now to review them.

English French

















N/A N/A N/A N/A 72547 72561 N/A N/A

Note: The tagline ******* Updated on YYYY.MM.DD ********* identifies the date the answer was revised. A brief description of the change, in square brackets, immediately follows the tagline.
