What this site is not

It is not medical advice and not a diagnostic tool. It is a reference copy of a statistical classification. Nothing here has been reviewed by a clinician. For patient care, consult a qualified professional; for coding decisions, consult the official WHO release and your national coding guidelines, which may differ from the international version.

This site is not affiliated with, endorsed by, or connected to the World Health Organization.

Where the data comes from

Directly from WHO's official ICD-API, with no intermediary. The methodology page documents the source, the release, the sync date and exactly what is and is not done to the text.
