Coding Guidance for Depression

F32 covers a single depressive episode and F33 recurrent major depressive disorder, both subdivided by documented severity: mild, moderate, severe, or unspecified. F32.9 is the default when severity is not documented.

The F33 series adds a fifth character for remission status, distinguishing major depressive disorder in partial remission (F33.41) from full remission (F33.42). Query the provider when severity or remission status is not clear from the record.

Depressive episodes occurring within bipolar disorder are coded from category F31, not F32 or F33, because the mood disorder classification depends on the overall pattern documented.
