ICD-10 Code F32.9: Major depressive disorder, single episode, unspecified
Mental and behavioural disorders
ICD-10 code F32.9 identifies a single episode of major depressive disorder of unspecified severity.
Coding guidance
The F32 category classifies single-episode major depression by severity: mild (F32.0), moderate (F32.1), severe without psychotic features (F32.2) and severe with psychotic features (F32.3).
Recurrent major depressive disorder is classified separately under F33.
F32.9 should be replaced with a severity-specific code whenever documentation supports one.
Documentation and specificity notes
- Document severity explicitly as mild, moderate or severe to support specific coding.
- Distinguish single episode (F32) from recurrent (F33) based on history.
- Severity specificity affects both risk adjustment and treatment authorization.
