What is Chronic Primary Pain?

Chronic Primary Pain is a new diagnosis from the WHO and IASP that has been added to the ICD-11. The ICD (International Classification of Disease) codes are used to classify diseases and other health problems. Insurance companies use them for billing and reimbursement.

Chronic primary pain is a condition characterized by pain in one or more body regions that persists longer than 3 months and is associated with significant emotional distress (like anxiety, anger, frustration, or depressed mood) and/or interferes with daily activities.  Chronic primary pain can occur in any body location (e.g., back, neck, face/head, limbs, abdomen, pelvis, and urogenital regions) or in any combination of body locations (e.g., widespread pain). Subtypes of chronic primary pain include chronic musculoskeletal pain, chronic widespread pain, chronic primary headache or orofacial pain, chronic primary visceral pain, and complex regional pain syndrome.

The diagnostic ICD-11 code for chronic primary pain is MG30.0. Additional codes may be appended to MG30.0 to indicate presence of psychosocial factors, degree of pain severity, emotional distress, pain-related interference, and temporal pattern/onset of pain.
