The article proposes a new diagnosis of chronic primary pain (CPP) in the International Classification of Diseases (ICD-11). CPP is defined as pain that persists or recurs for more than 3 months, is associated with significant emotional distress and/or functional disability, and is not better accounted for by another condition. The classification aims to provide a clear, multifactorial framework for understanding CPP, integrating biological, psychological, and social factors. Unlike previous classifications, CPP is considered a distinct diagnosis independent of identified biological or psychological contributors, unless another diagnosis better accounts for the symptoms. The classification includes subtypes such as chronic widespread pain, fibromyalgia, complex regional pain syndrome, chronic primary headache, orofacial pain, visceral pain, and musculoskeletal pain. The goal is to create a useful classification for both primary care and specialized pain management settings, aiding in the development of individualized management plans and providing a more accurate description of each diagnostic category. The article also discusses the need for a classification that avoids vague terms and emphasizes the importance of multimodal interventions to address the contributing factors of CPP.The article proposes a new diagnosis of chronic primary pain (CPP) in the International Classification of Diseases (ICD-11).
