6E62

ICD-11 MMS 2026-01

Secondary mood syndrome

Description

A syndrome characterised by the presence of prominent mood symptoms (i.e., depression, elevated mood, irritability) judged to be a direct pathophysiological consequence of a health condition not classified under mental and behavioural disorders, based on evidence from the history, physical examination, or laboratory findings. The symptoms are not accounted for by delirium or by another mental and behavioural disorder, and are not a psychologically mediated response to a severe medical condition (e.g., depressive symptoms in response to a life-threatening diagnosis). This category should be used in addition to the diagnosis for the presumed underlying disorder or disease when the mood symptoms are sufficiently severe to warrant specific clinical attention.
