Major depressive disorder, recurrent (F33)
ICD-10 code F33 and its subcodes classify various forms of major depressive disorder, recurrent, distinguishing the severity and current status of symptoms. These codes are used to document repeated episodes of depression, ranging from mild and moderate to severe, including cases with psychotic features or remission phases.
The ICD-10 code for major depressive disorder recurrent includes nuanced categories: F33.0 and F33.1 identify mild and moderate recurrent depressive episodes, often referred to by synonyms like "mild recurrent major depression" and "moderate recurrent major depression." More severe forms without or with psychotic symptoms fall under F33.2 and F33.3, encompassing conditions such as "severe seasonal affective disorder" or "severe recurrent major depression with psychotic features." Remission stages are captured by F33.4 and its subcodes (F33.40, F33.41, and F33.42), covering partial to full remission of recurrent major depression. Other distinct recurrent depressive disorders are recorded under F33.8, and unspecified recurrent major depression, which includes "chronic depression" and "seasonal affective disorder," is coded as F33.9. These specific ICD-10 codes help healthcare professionals precisely classify and treat the varying presentations of recurrent major depressive disorder.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Seasonal Affective Disorder
A syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months. Other symptoms include anxiety, irritability, decreased energy, increased appetite (carbohydrate cravings), increased duration of sleep, and weight gain. SAD (seasonal affective disorder) can be treated by daily exposure to bright artificial lights (PHOTOTHERAPY), during the season of recurrence.
