A Revision Steering Group (RSG) served as a consultative expert authority during the revision process from December 2007 through October 2016. The primary focus of the RSG was to provide guidance through reviewing the content to ensure adequate coverage of the full scope of health care diseases and related health conditions while addressing the needs of users.



The RSG is composed of the Co-Chairs of each content and classification Topic Advisory Group, as well as the co-chairs of the WHO-FIC Network and the WHO-FIC Committees and Reference Groups. The RSG is coordinated by a Small Executive Group known as the RSG-SEG, which includes the RSG Chair as well as six other individuals with broad areas of expertise drawn from the RSG.



Topic Advisory Groups served as the planning and coordinating advisory bodies for specific issues which are key topics in the update and revision process, namely Oncology, Mental Health, External Causes of Injury, Communicable Diseases, Non-communicable Diseases, Rare Diseases and others.



The primary charge of each group was to advise WHO in all steps leading to the revision of topic sections of ICD in line with the overall revision process. This included, in particular, advising on the development of various drafts of topic segments in line with the overall production timeline, reviewing and commenting on proposals from other stakeholders and experts while consolidating all input to achieve consistency across groups and areas, and many other tasks as outlined in the Terms of Reference for TAGs.



More than 200 scientists and other experts from more than 35 countries and all WHO Regions have contributed to the work.
