ICD-11 disorder and condition catalogue

This catalogue organises ICD-11 diagnostic entities by name and code so that a working diagnosis can be checked against a more precise clinical description. It includes broad disorder groups as well as detailed subcategories, making it useful for reviewing criteria, core symptoms, exclusions and relationships between similar diagnoses.

In clinical work, the category name alone is rarely enough. Assessment should consider symptom duration, severity, functional impact, developmental context, possible medical causes, substance use and other disorders that may produce a similar presentation. The detailed catalogue pages are designed to help gather these points in a more structured way.

The list can support ICD-11 learning, clinical documentation, comparison with ICD-10 and planning of differential diagnosis. The content is informational and does not replace examination, history taking or the judgement of a qualified professional.
