The World Health Organization (WHO) has adopted the 11th version of the International Classification of Diseases (ICD-11). ICD-11 is the latest revision of the International Classification of Diseases.
For the first time, it will include a new classification system for chronic pain. The inclusion of diagnostic codes for chronic pain along with codes for the most common and clinically relevant groups of chronic pain conditions is a significant milestone for the pain field.
The classification system for chronic pain has been developed by a Task Force under the International Association for the Study of Pain (IASP) in collaboration with WHO. The decision to adopt the ICD-11 was made at the World Health Assembly on 25 May 2019 and comes into force as of 1 January 2022.
