Classifications and Terminologies highlights

Coding direction: Vaping-related disorders

Effective October 1, 2019, there is a new coding direction for assigning an ICD-10-CA code for vaping-related disorders. This is in accordance with the World Health Organization (WHO) directive for international data collection. Please refer to the bulletin and to eQuery coding questions 74256 (English) and 74258 (French) for details.

Changes to v2021

The status of requested changes for v2021 of the Canadian Coding Standards [AC1] (as of November 2019) is now available.

ICD-10-CA and CCI Enhancement Requests for v2021 (as of August 30, 2019) is now available and will be updated in January 2020. It provides the status of the request, as well as the decision and rationale. Approved requests will appear in v2021 of the ICD-10-CA and CCI.

Please continue to check the Codes and Classifications web page for updates.

Now open: Public submission for ICD-10-CA and CCI v2024

We are now accepting enhancement requests regarding the classifications for v2024. To submit a request, please refer to the Public Submission Guidelines for Updating ICD-10-CA and CCI and complete the public submission request form.

Revision to iCODE case study (course 459E)

Issue: An error was identified in Learning Centre course 459E — iCODE Case Study: Pathological Periprosthetic Fracture and Postoperative Low Hemoglobin, which is part of the 5001E — Practice with iCode learning bundle. Type 2 diabetes mellitus was classified incorrectly.

Correction: The code assignment for this case has been corrected. When acute renal failure is diagnosed in a patient with diabetes mellitus and the underlying cause is noted (e.g., dehydration, volume depletion), the acute renal failure is classified to N17.9 and a code for the underlying cause is assigned; E1–.28 is not assigned. Type 2 diabetes mellitus with acute on chronic kidney disease, when the acute component is due to dehydration, is classified to N17.9, E86.8, E11.23 and N08.39 (both E11.23 and N08.39 are required because the dagger and asterisk convention applies).


ICD-11 series

Part 3 of the webinar series, An introduction to ICD-11 is now available on the Codes and Classifications web page. A live webinar with stakeholders across Canada was recorded on September 25, 2019. The webinars have been re-recorded to reflect changes made to the ICD-11 coding tool by the World Health Organization (WHO) in October 2019. For more information on updates to the coding tool, please refer to the WHO ICD-11 Coding Tool Help.

Previous webinars in this series: An Introduction to ICD-11: Part 1 and An Introduction to ICD-11: Part 2

For future sessions

These webinar series are not available in CIHI’s Learning Centre and do not require registration. Webinar details (e.g., topic, date, instructions for access) will be circulated via email. If you would like to be informed about future webinars, please email classifications@cihi.ca.

Coding questions

New: Archived/revised coding questions

Based on client feedback, we are creating a list of all archived and revised coding questions from 2015–2016 to September 30, 2019. Rationale for decisions will be included. We anticipate posting this on the Codes and Classifications web page by April 2020.

Reminder: Translation of English coding questions to French

Beginning with coding questions related to 2019–2020 data, English questions viewable in the eQuery database will be translated into French. This will continue as we move forward.  

Updated coding questions

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

The following coding questions have been revised and updated since June 2019. Log in to eQuery now to review them.









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.
