Chronic Primary Pain

Chronic Primary Pain

Chronic Pain has been Reclassified in the ICD-11

This became effective on in January 2022 after a creative collaboration between World the Health Organization (WHO) and the International Association for the Study of Pain (IASP).

The new system provides a single diagnostic code for chronic pain (MG30.0 Chronic primary pain).

Under the ICD-11 pain is not only recognized as a health condition on its own but it is also recognized as a symptom that can be secondary to other underlying health issues.

Under the new classification Chronic pain defined as Primary ( pain that persists or recurs for more than 3 months - as it had been previously) or secondary to organic causes.

The new definition of chronic primary pain is an important step forward and is neutral concerning the historical misleading dichotomy between somatic vs mental disorders.

It Includes important components of emotional distress and functional disability.
