Revision of the International Classification of Diseases (ICD-11)
Chronic pain affects an estimated 20 percent of people worldwide and accounts for nearly one-fifth of physician visits. One way to ensure that chronic pain receives greater attention as a global health priority is to improve the International Classification of Diseases (ICD) diagnostic classification.
In response to this need, IASP created an international task force of pain experts headed by past president Rolf-Detlef Treede that, in close cooperation with the World Health Organization (WHO), has developed a proposal for a systematic and pragmatic classification of chronic pain. This new classification of chronic pain has been implemented in the ICD-11 frozen version for preparing implementation. The ICD-11 was approved on May 25, 2019. It will come into effect on January 1st, 2022.
