Slide #3: ICD-11 MMS
ICD-11 for Mortality and Morbidity Statistics has been released and is now available. Version 2022 of ICD-11 came into effect on February 11, 2022. It is multilingual and available in several different languages such as English, French, and Spanish. There’s been no decision yet about implementation in Canada.
Slide #4: ICD-11 features
ICD-11 has many benefits and features. It is designed to be used in electronic health information systems and will better reflect progress in health sciences and medical practice. It is entirely digital with an offline functionality, so it is accessible to everyone. New diagnoses and conditions have been incorporated into ICD-11. There are 17,000 statistical categories and codes. There are over 100,000 medical diagnostic index terms, and the index-based search algorithm interprets more than 1.6 million terms. This expanded content enables enhanced coding possibilities.
A digital Reference Guide is available with instructions on how to use ICD-11. As mentioned before, it is a multilingual browser. It was also built to be interoperable with other classifications and terminologies such as the International Classification of Diseases for Oncology also known as (ICD-O) and Orphanet.
This allows the classification to be used for multiple use cases such as primary care, quality and safety, mental health, rare diseases coding, perinatal and maternal coding, cancer coding and more.
ICD-11 has a foundation component which provides the overarching repository from which concepts can be drawn into specific classifications (linearizations) such as mortality, morbidity, epidemiology, case mix, primary care, research, functioning and disability and quality and safety. More specifically, the foundation component of ICD-11 is a multidimensional collection of all ICD entities, the diseases, disorders, injuries, external causes, signs and symptoms.
Slide #5: ICD-11 home page
ICD-11 can be accessed from the World Health Organization’s ICD website. On the ICD-11 home page, there are hyperlinks to the 2 main ICD-11 electronic tools: the ICD-11 browser and the Coding Tool. There’s also a link to the ICD-11 Reference Guide, which we will talk more about in this presentation, as well as links to fact sheets and training material.
Slide #6: ICD-11 Electronic tools
The first ICD-11 electronic tool we will explore is the browser. This tool contains the tabular list. It displays the hierarchy of ICD-11 and all associated information about each category or codable entity.
The second tool is the Coding Tool. It serves as an alphabetical index but acts like a web-based search. There is no need to search for lead terms and secondary terms. The Coding Tool is linked to the ICD-11 browser to access further details on a category or code in the classification.
Slide #7: ICD-11 browser - Demo
The ICD-11 online browser allows access to the tabular list of ICD-11. There are navigation tabs, including an Info tab. Here you can access a User Guide, the ICD-11 Reference Guide, print versions and more. Clicking the Coding Tool tab will take you directly to the tool.
The ICD-11 hierarchy is displayed on the left side of the screen. Once you select a code, all the code’s associated information is displayed to the right of the hierarchy.
In the top right corner of the screen, you can select different languages. Clicking a language with a single arrow beside it will display 2 languages side by side for comparison purposes. Or you can change the language for the entire browser and Coding Tool by selecting a language with no arrow. To go back to the original language, simply click the language that you want to access.
Slide #8: ICD-11 Coding Tool - Demo
The Coding Tool is an electronic index that can be searched to help find ICD-11 terms. You can click the Help tab for guidance on how to use the tool. The Coding Tool includes smart search features such as word prediction, so when you start typing in the search field, a list of possible terms will appear on the left. You can select words from the Word list or type in the entire term manually.
All search results are displayed and referred to as Destination Entities.
The tool will show any matching terms that are available and, when appropriate, will also show any inclusions and exclusions for a selected code. If you click See in hierarchy, it will lead to a built-in integrated browser. Here you can see the code details along with postcoordination, which will be explained shortly. You will also see an interactive code hierarchy to the left to ensure you have selected the most specific code available for the clinical term or phrase you are looking for.
Slide #9: ICD-11 terminology
We will now explore some of the terminology used in ICD-11. We’ll start with stem codes.
Slide #10: Stem codes - Demo
Stem codes are located in the tabular list of ICD-11. These codes are specifically designed to collect a meaningful minimum of information for use cases that require only 1 code per case. These may be entities or groupings of high relevance, or clinical conditions that should always be described as a single category.
Stem codes can be used alone or linked together with other stem and/or extension codes. For example, looking at the code NC72.5 Fracture of shaft of femur, we can see that all the details in the code title are able to tell us the diagnosis and it does not need further details added.
Slide #11: Extension codes - Demo
Extension codes are another type of code available in ICD-11. They can be found in Chapter X: Extension Codes. They all start with the letter X and are designed to standardize the way additional information is added to stem codes. These codes can be used optionally to add further details to a stem code, such as severity detail and laterality. Extension codes can not be used without a stem code as they do not provide enough detail on their own.
Looking again at NC72.5 Fracture of shaft of femur — if we want to add more details to this code, such as indicating that the fracture is of the right leg, we can add an extension code.
Extension codes that are commonly added are already listed for you. Here we can see that laterality is available at the code, so we can select Right to indicate that the fracture is of the right leg.
Slide #12: Precoordination
Precoordination is a term used in ICD-11 to describe codes that contain all pertinent information about a clinical concept in a pre-combined fashion — meaning that no further codes are required if no further details are available. For example, BD50.40 Abdominal aortic aneurysm with perforation is a pre-coordinated code. This code provides enough detail to describe a patient condition.
Slide #13: Postcoordination - Demo
Postcoordination refers to the use of multiple codes together to fully describe a documented clinical concept. Any combination of post coordinated codes is called a cluster. This can be a combination of 2 or more stem codes, or a stem code linked to an extension code.
Postcoordination requires the use of a convention (either a forward slash or an ampersand) to show a link between multiple codes describing a documented clinical concept:
- A forward slash (/) is used between stem codes.
- An ampersand (&) is used to separate stem codes from extension codes.
If we look at BD50.40, we can see that the code title simply states abdominal aortic aneurysm with perforation. If we want to be more specific and say infrarenal abdominal aorta, we can select the extension code to provide that extra detail for the original stem code.
Slide #14: ICD-11 resources
ICD-11 has multiple resources to help users navigate and use both the ICD-11 browser and Coding Tool.
Slide #15: ICD-11 help - Demo
Under the Info tab, there is a User Guide that provides detail on how to browse the hierarchy and search for terms in the browser. There’s also a Reference Guide, which we will explore shortly.
As mentioned before, you can also find the Help section for the Coding Tool by clicking the Coding Tool tab and then clicking the Help tab in the top right-hand corner. This Help section provides guidance on navigating and searching the Coding Tool.
Slide #16: ICD-11 Reference Guide - Demo
The Reference Guide contains an introduction to the diverse components of ICD-11. This guide is not exhaustive; however, it includes information and guidance on context, components and intended use, as well as rules for mortality and morbidity coding.
It is divided into 3 parts:
- Part 1 is an introduction to ICD-11.
- Part 2 describes how to use the classification.
- Part 3 explores what’s new in ICD-11.
Slide #17: Summary
Now let’s look at ICD-11 to summarize what we have covered.
Slide #18: Summary demo
On the ICD-11 home page, we can see direct links to the ICD-11 browser and Coding Tool. You can also access the ICD home page, which provides information on the benefits and features of ICD-11. From there, you can access the Reference Guide, a fact sheet, licensing information and training. Let’s click the browser link to see the main screen of ICD-11. You can access the Coding Tool here as well by clicking the Coding Tool tab. From the Info tab, we can again locate the User Guide and Reference Guide.
To see stem and extension codes in the browser, we can explore the hierarchy to the left of the screen. Once you select a code, you will see all the code’s details to the right of the hierarchy. You can compare languages at the same time by clicking the language icon and choosing a language with a single arrow. Or you can select a language option without an arrow to switch the entire browser and Coding Tool to a different language.
Let’s now navigate to the Coding Tool. This is where we will find the Help section for information on how to navigate the Coding Tool and how to search for clinical concepts. You can either scroll down to search the information or select a specific topic at the left of the screen. If we then type in a term such as heart failure, we can see that the Coding Tool will instantly provide us with Destination Entities and a word list to the left of the screen to help us with our search. We can select extra terms from the word list — congestive, for example — or type directly in the search bar like a web-based search.
Once we have our search terms, we can then review any highlighted codes and additional Destination Entities that are displayed. When you click the Details button, you will see all the code details, including matching terms, inclusions and exclusions, and chapter-specific notes. You can then click See in hierarchy to access the integrated browser. This lets you review the code details. You can navigate the hierarchy on the left for more specific codes. You can also review any postcoordination available for the selected code. When applicable, postcoordinated codes will be linked together by a slash and/or an ampersand, depending on the type of code selected.
Let’s navigate back to the main page of the ICD-11 browser. Under the Info tab, we will now review the ICD-11 Reference Guide. To access the information in this guide, we can directly type in the search bar. If we type the word postcoordination and click Enter, any section that talks about postcoordination will be highlighted. We can also expand or scroll through the sections in the guide for more details on a specific ICD-11 concept.
Slide #19: Resources
There are lots of resources for ICD-11, but these are the main ones for guidance on how to navigate and use the ICD-11 applications.
Slide #20: WHO links
Here are the links to the ICD-11 pages that we reviewed during this webinar: the ICD-11 home page, the browser, the Coding Tool, Coding Tool help and the reference guide.
