The ICD-11 replace the ICD-10 as the global standard for coding health information and causes of death. Its development started in 2007 and spanned over a decade of work, involving over 300 specialists from 55 countries with an additional 10,000 proposals from people all over the world.

Gaming disorder has been newly added to the ICD-11, and placed in the group "Disorders due to addictive behaviours", alongside Gambling disorder. The pattern of gaming behaviour results in marked distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning. The gaming behaviour and other features are normally evident over a period of at least 12 months in order for a diagnosis to be assigned.

ICD-11 contains several new chapters, in particular on alternative medicine and sexual health. Approaches to the classification of stroke have changed: it is now a disease of the brain, not the circulatory system. Specific symptoms for the diagnosis of PTSD have been clarified and a complex post-traumatic stress disorder has been added. Special codes for antibiotic resistance have been introduced to help more accurately measure the effectiveness of drugs.
