Australian Collaborating Centre for the World Health Organization Family of International Classification

Health Classifications Update 9 – January 2026

Welcome to the Australian Institute of Health and Welfare’s (AIHW’s) 9th Health Classifications Update.

This update includes news from the World Health Organization Family of International Classifications (WHO-FIC) annual meetings held in Geneva in October 2025. There were approximately 160 people from many countries and collaborating centres which allowed a wide and varied discussion of many topics.

Australia made a bid, subject to funding, to host the WHO-FIC Network 2026 annual meeting in Sydney in October. The WHO-FIC Network supported our bid. If we are successful in funding this bid, then it will be a great opportunity to enhance collaboration between the WHO-FIC Network and SNOMED International, which is having its Expo in Sydney at the same time. Here at the AIHW we are continuing the work to understand the costs and benefits of, and likely path for, implementing ICD-11 in various use cases.

In addition to this,

  • The Independent Health and Aged Care Pricing Authority (IHACPA) has engaged a consultancy to develop a business case for replacing ICD-10-AM with ICD-11, with a final report expected in June 2026. 
  • The Australian ICD-11 Task Force (AITF) is developing the business case for a wider implementation which will include information from the IHACPA work. 

AIHW, IHACPA and the Australian Bureau of Statistics (ABS) have continued engaging with other countries that are also embarking on their ICD-11 implementation journey – the questions and issues we are all facing are similar, even where our systems are different, so sharing knowledge during this period will be crucial. More information about this is discussed later in this update.

Preparations will be starting soon for the WHO-FIC mid-year meetings which will (mostly) be virtual meetings, and the Australian Collaborating Centre (ACC) secretariat has the big job of finding funding for the WHO-FIC annual meetings (wish them luck folks there is a lot of moving parts to juggle when organising international meetings).

Australian updates

AITF activities

The Australian Health Classifications Advisory Committee (AHCAC) established the AITF in 2022 to develop a multi‑year Roadmap of activities to inform a decision on implementing ICD‑11 across a range of Australian use cases.

The key deliverable of this Roadmap is a business case for government on ICD‑11 adoption. This will incorporate the findings of the IHACPA business case, due for completion in June 2026; the AITF business case will be finalised thereafter.

The Task Force includes representatives from all states and territories, the ABS, IHACPA, the Australian Digital Health Agency (ADHA), the Australian Commission on Safety and Quality in Health Care (ACSQHC), the Department of Health, Disability and Ageing (DHDA), the Department of Veterans’ Affairs (DVA), and the Australian Centre for Disease Control (CDC).

What happened in the second half of 2025?

The AIHW has been consulting national agencies, state and territory health departments and other identified stakeholders. As part of these consultations, potential demonstration projects were explored that could provide evidence of the value of ICD-11 for the ICD-11 business case.

  • From September - December 2025, the AIHW consulted with the ACT Health Department, Northern Territory Health Department, the University of NSW Faculty of Medicine, the Australian Digital Health Agency, the Royal Flying Doctor Service, the Australian Interim CDC, Calgary University and the Australian Commission for Safety and Quality in Health Care (ACSQHC) where ICD-11 demonstration projects were discussed.
  • Consultations will be undertaken in the coming months with the Therapeutic Goods Administration and the Department of Health, Disability and Ageing.
  • Planning has commenced for a second round of consultations with agencies/jurisdictions where written input will be sought on specific questions to fill gaps in the evidence required for the business case.

In collaboration with IHACPA, the AIHW developed a set of key messages to ensure consistent communication across governments and to promote the potential of ICD-11 to a range of stakeholders.

  • The AIHW sought feedback from the AITF at its September meeting on the key messages for ICD-11 for a range of audiences, including prioritisation of and communication channels for these. 
  • A communications plan is being prepared by the AIHW in consultation with the AITF and will be presented to the Australian Health Classifications Advisory Committee (AHCAC), with the key initial focus of the communications being on decision makers and funders of the work, with a view to getting implementation work resourced. Subsequent emphasis will be given to a broader range of audiences who will be important at various stages of this long-term project.

An AITF Workforce Task Group was formed to look at the impact of ICD-11 on the workforce. This group is developing a high-level document identifying stakeholders within the health industry, the type of workforce that will be required and transition requirements, impacts and costs. 

A draft workforce assessment report was presented to the AITF meeting, including key overarching considerations and recommendations. The draft report was circulated out of session to the AITF for feedback by end of January 2026. The findings of this report will inform the business case, and be used to determine requirements, cost and timeframes for workforce issues related to ICD-11 use in Australia.

The draft outline of the ICD-11 business case was endorsed by the AITF in July 2025. It is being populated with the information available from the Roadmap tasks. This is being approached from a lens of ‘what do we already know?’, and therefore, ‘what do we still need to find out?’. A preliminary draft will be discussed at the next AHCAC meeting in early 2026.

Do you want to get involved in the AITF activities?

As part of the AITF Roadmap tasks to inform the ICD-11 business case, there is a task called Sample Data Explorations.

For example, here at the AIHW we have been looking at our key reports and working with various teams to ask, ‘what do we report on now?’, ‘what would we like to report on but can’t (i.e., data gaps)?’, ‘what can ICD-11 do for us moving forward?’.

So far, the AIHW has commenced data explorations on the following topics:

  • Antimicrobial Resistance (in conjunction with the Australian CDC)
  • Gender Incongruence (in conjunction with the Royal Children’s Hospital in Melbourne)
  • Suicide and Self Harm
  • Chronic Pain
  • Dementia
  • Diabetes and its complications
  • Family and Domestic Violence.

Is there a topic that you are particularly interested in seeing how ICD-11 would improve health data capture and reporting?

It can be as big or small as you can want, from 100 cases to a 1000 or more!

We are looking for projects that you can complete by June 2026.

Contact the classifications team at the AIHW at [email protected] to discuss what you can do to help inform the ICD-11 business case.

ACC international engagement

The ACC engages regularly with other WHO-FIC Collaborating Centres to share implementation planning experiences and lessons.

In the second half of 2025, the ACC met with international counterparts from the following countries to find out about work that they have done on ICD-11 planning and lessons learnt that could be applicable in Australian context.

The ACC will continue to engage with these and other countries as we learn of their progression in ICD-11 implementation and data usage.

International ICD-11 planning
Country/ OrganisationPlans

Malaysian Flag

Malaysia

Since 2023, Malaysia has transitioned its national health data system and some of its hospital information systems to ICD-11 and is now reporting nationally using ICD-11. Malaysia’s challenges include managing legacy systems, vendor dependencies, and outdated infrastructure. Malaysia is planning to visit the ACC in July 2026.

German Flag

Germany

The German ICD-11 implementation strategy has an emphasis on documentation-based approaches using SNOMED CT and ICD-11. The German centre noted that mapping between the two will not be sufficient. User-driven data, iterative testing and demonstration projects in new domains are planned to provide valuable lessons.

Netherland Flag

The Netherlands

The Netherlands national vision was to link and harmonise core standards for health information exchange. There is ongoing debate on using classifications vs. terminologies for different use cases; there is a push for “semantic unification” and using the right tool for the right purpose. Implementation of ICD-11 is estimated to be by 2031.

Canadian Flag

Calgary University (Centre for Health Informatics), Canada and the ACSQHC

Calgary outlined that it is developing ICD-11 indicators to update the Elixhauser and Charlson comorbidity measures, which have shown substantially better performance in prediction of adverse events in a dataset.

The ACSQHC shared its experiences with data for patient quality and safety (Q&S) measuring and reporting in Australia, and some of the challenges such as having state-based repositories for Q&S and not a national one. 

Norway FlagSwedish Flag

Nordic CC
(Sweden and Norway)

There is a Nordic ICD-11 Task Force which Sweden and Norway are participating in.

Sweden is expecting implementation for mortality in 2027 and admitted care in 2028, with the translation into Swedish having been completed.

Norway has not made a decision on when to implement in admitted care but is estimating 2028-29.

Canadian Flag

Canadian CC (Canadian Institute for Health Information (CIHI) and Statistics Canada)

Canada is working on the governance of transition to get a national mechanism for making health data decisions rather than one for each province. A Pan-Canadian Task Force is being formed with membership from all provinces, federal government agencies, as well as some non-government organisations that are data and/or research based. 

CIHI is reviewing Canadian health system performance indicators which use ICD coded data but also looking at the legacy of what it produces and opportunities to enhance its casemix and health system performance measures. 

Statistics Canada is awaiting the upgrade of Iris to ICD-11 to enable it to move to ICD-11 for mortality. The aim for implementation is to have mortality and morbidity implement around the same time.

United Kingdom Flag

The United Kingdom National Health Service (NHS)

The UK has been considering its ICD-11 implementation approach and has decided not to go with a “Big Bang” approach where all of NHS would move across at the same time, especially due to recent significant change to the organisation. An approach similar to Malaysia may be used (i.e., a phased roll out, using mappings in the interim).

Japanese Flag

Japan Society of Health Information Management

A delegation came to Australia in December 2025 and held in person meetings with IHACPA in Sydney and AIHW in Canberra (with ABS virtually attending the AIHW meeting).

Japan plans to implement ICD-11 for mortality by 2027. Its challenges are workforce limitations, translation of ICD-11 and associated tools, quality of clinical documentation, and establishing standardised use of extension codes.

Japan is exploring the use of AI assisted coding and automated coding to address workforce and resource constraints, while noting the need for human involvement for validation and quality control.

IHACPA activities

IHACPA is continuing to work on projects within its Framework for a decision to implement ICD-11. 

Key achievements to date include:

  • ICD-11 maturity assessment

    ICD-10-AM to ICD-11 mapping project – the gold standard maps are being finalised and the backward mapping process from ICD-11 to ICD-10-AM has started.

  • ICD-11 classification architecture

    An ABF Classification modernisation project – a statement of requirements is currently being written. 

  • ICD-11 stakeholder engagement and governance

    Results from IHACPA’s future classifications consultation paper (Oct 2025) are now under review, and recent stakeholder engagement is informing the cost‑benefit analysis for transitioning from ICD‑10‑AM to ICD‑11.

For further information on IHACPA’s ICD-11 activities please see the ICD-11 webpage on the IHACPA website.

ABS activities

Over the last six months the ABS has continued to work on a plan for how ICD-11 could be implemented for mortality in the Australian setting. The work has included a mixture of contributing to ICD-11 proposals and enhancements as part of the ABS’ role in the WHO-FIC Mortality Reference Group and working through testing the suitability for the Australian mortality data, as well as what needs to be considered as part of an implementation plan.

Over the next six months the ABS ICD-11 work program will continue with planned activities including:

  • Dual coding exercises for specified mortality cases. The aim of these will be to examine where changes occur the most between ICD-10 and ICD-11 (for example, drug-induced deaths) and to showcase the capabilities possible with ICD-11.
  • Testing the new version of Iris (the automated coding software for mortality) for ICD-11.
  • Continuing to look at opportunities for AI and its ability to support coding.

International Classification of Functioning, Disability and Health Australian Interest Group (ICF-AIG)

The ICF-AIG is a collaborative, multidisciplinary group of people who have diverse expertise in data development, the ICF and its uses. The group meets two or three times a year. The October 2025 meeting included presentations and discussions on the following topics:

  • The Instrument for the Classification and Assessment of Support Needs (I-CAN) for supporting the National Disability Insurance Scheme (NDIS) needs assessment – It has been announced that I-CAN, version 6, will be used to develop a new support needs assessment process for NDIS participants. The I-CAN has been developed and refined over 20 years by the Centre for Disability Studies (CDS). The University of Melbourne is partnering with CDS to help the National Disability Insurance Agency develop an assessment process. I-CAN is conceptually based on the ICF. It has 12 domains: the 9 ICF activity/participation chapters, plus Behaviours of Concern, Mental & Emotional Health, and Physical Health. In discussion, members noted the importance of including environmental context in support needs assessments, and for the assessment process to be co-designed with people with disability.
  • NDIS Evidence Advisory Committee (EAC) – Dr Louise O’Rance, Assistant Secretary, Department of Health, Disability and Ageing, gave a guest presentation on the new NDIS EAC. The EAC will provide advice to government on the suitability of supports for NDIS funding. The assessment process for supports will include public consultation, evidence synthesis, and technical review (subcommittees assess benefits, safety and cost-effectiveness). The EAC’s recommendations to government will consider target populations, delivery settings, dosage, provider qualifications and contextual factors affecting cost-effectiveness. There will be an emphasis on framing recommendations around functioning goals and impairments, rather than diagnoses. For information about the EAC and its three technical subcommittees, see: NDIS Evidence Advisory Committee | Australian Government Department of Health, Disability and Ageing

The next ICF-AIG meeting will be on 12 March 2026. If you would like to find out more about the ICF-AIG, please contact [email protected].

WHO-FIC Network update

The WHO-FIC Network is an extensive network of country collaborating centres (CCs), academic institutions and individual experts that help guide the development of the WHO classifications.

Australia participates actively in the WHO-FIC Network committees and reference groups (CRGs), and the AIHW (as the Australian CC) extends its thanks to its members from a range of national stakeholders, such as the ABS, AIHW, IHACPA, various universities and others, for their past, present, and future involvement and shared expertise.

Engagement with the WHO-FIC Network is important to maximise the utility and benefit of the WHO classifications, in particular ICD-11, for Australia by promoting early influence and strategic preparation to ensure that Australia’s use cases and unique requirements are considered in the development, implementation, and ongoing updates to the classifications.

WHO-FIC Network 2025 Annual Meetings

The 2025 Annual Meetings were held at WHO Headquarters in Geneva, Switzerland, October 13-18. These meetings were held to progress the work on developing the classifications and to provide opportunities for collaboration between all of the CRGs.

The WHO-FIC CRGs are the:

  • Classification and Statistics Advisory Committee (CSAC)
  • Education and Implementation Committee (EIC)
  • Family Development Committee (FDC)
  • Informatics and Terminology Committee (ITC)
  • Medical and Scientific Advisory Committee (MSAC)
  • Health Interventions Reference Group (HIRG)
  • Mortality Reference Group (MRG)
  • Morbidity Reference Group (MbRG)
  • Functioning and Disability Reference Group (FDRG)
  • Traditional Medicine Reference Group (TMRG)
  • Verbal Autopsy Reference Group (VARG)

Key outcomes from the 2025 meetings include:

  • CSAC-ICD reviewed and made decisions on 180 ICD-11 proposals in 2025, with 154 being accepted for ICD-11 and the Reference Guide
  • HIRG reviewed 66 International Classification of Health Interventions (ICHI) proposals in 2025, with 36 accepted. Work continues on the development of the ICHI Reference Guide and education materials
  • CSAC-ICF triaged 15 proposals in 2025, with 12 being implemented. Work continues on a Guide for submission of ICF proposals
  • EIC had 11 presentations from countries regarding their activities for ICD-11 implementation planning. They also endorsed changes to sections of the ICD-11 Reference Guide which included a new section on translations 
  • FDC continue to work on content alignment and harmonisation between the classifications. The Primary Care Working Group continued its work on assessing the coverage of “Reason for Encounter” in ICD-11, and work continues in linkage of ICD-11 to other terminologies including SNOMED CT
  • FDRG continue the work to elicit use cases and examples for inclusion in the ICF Reference Guide, as well as enrichment of the ICF Foundation content
  • ITC had presentations on the use of AI and large language models for automated coding and mapping
  • MbRG continued its discussions of the need for national linearisations of ICD-11, including governance principles ensuring accountability, consistency, and alignment with the WHO ICD-11 Foundation and MMS. They also had topic specific working sessions on classification of injuries and maternal care
  • MRG focused its time on how to improve mortality coding tools to allow for increased automation, which will improve mortality data quality, as well as the review of Reference Guide proposals for mortality coding rules
  • MbRG and MRG had a cross over meeting to discuss key issues which impact both morbidity and mortality classification, such as Medical Aid in Dying, traffic and non-traffic accidents, e-scooters and polytrauma
  • At the WHO-FIC Council session there was feedback and input on the running of annual meetings, and discussion as to how the CRGs can better engage with each other.

ICD-11 update

The 2026 release of the ICD-11 Browser, Coding Tool, Reference Guide and the Implementation or Transition Guide are expected to be available in late February, encompassing changes accepted in the 154 proposals processed by CSAC-ICD, updates endorsed by the CRGs at annual meeting, as well as tooling improvements.

CSAC-ICD Voting Round 1 which is the process for endorsing proposed changed to ICD-11 will commence after the CSAC-ICD Small Group meeting in April 2026.

Recent ICD-11 resources

ICF update

The FDRG has continued the development of the ICF Reference Guide. 

ICF update proposals continue to be triaged by the CSAC-ICF co-chair, secretariat and the WHO. It is anticipated that a small number will come to CSAC-ICF members later this year for voting.

For more information about ICF visit the WHO’s ICF home page.

ICHI update

HIRG will continue its work with platform proposals, enriching ICHI content and the review of the Nordic casemix system, NCSP+, mapping work which will inform a WHO DRG Grouper as its main priorities for 2026. These are very large pieces of work that must be completed to make ICHI ready for Member State consultation prior to approval by the World Health Assembly.

The updated ICHI Reference Guide has been added to the ICHI maintenance platform and basic education material developed is with WHO for review.

Both of these items will continue to be updated especially once ICHI is approved and a frozen version released.

For more information about ICHI visit the WHO’s ICHI home page.
