MG30.03 Chronic primary headache or orofacial pain

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2025-01

Chronic primary headache or orofacial pain is defined as headache or orofacial pain that occurs on at least 50% of the days during at least 3 months. It is characterised by significant emotional distress (anxiety, anger/frustration or depressed mood) or functional disability (interference in daily life activities, reduced participation in social roles). Chronic primary headache or orofacial pain is multifactorial: biological, psychological and social factors contribute to the pain syndrome. The diagnosis is appropriate independently of identified biological or psychological contributors unless another diagnosis would better account for the presenting symptoms. The duration of pain per day is at least 2 hours.
