ICD-10 Code F33.0: Major depressive disorder, recurrent, mild
Mental and behavioural disorders
ICD-10 code F33.0 identifies recurrent major depressive disorder with a current episode of mild severity.
Coding guidance
The F33 category is used when there is a history of at least one prior major depressive episode.
Severity of the current episode determines the fourth character.
Documentation must establish the history of prior episodes to support F33 rather than F32.
Documentation and specificity notes
- Document the history of prior depressive episodes explicitly.
- Recurrent depression carries different risk-adjustment weight than single episode.
- Reassess and update severity at each visit.
