About F33

F33 is the ICD-10-CM diagnosis code for major depressive disorder, recurrent. It belongs to block F30-F39 (mood [affective] disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: F33.0 (mild), F33.1 (moderate), F33.2 (severe without psychotic features), F33.3 (severe with psychotic symptoms), F33.4 (in remission), F33.8 (disorders) and F33.9 (unspecified).

Don't report F33 together with the conditions in its Excludes1 note: bipolar disorder (F31.-) and manic episode (F30.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
