Revision of the International Classification of Diseases (ICD-11)

Giving chronic pain the greater attention it deserves as a global health priority.

About ICD-11

About ICD-11

Chronic pain affects an estimated twenty 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 25 May 2019. It will come into effect on 1 January 2022.
