Seasonal Affective Disorder
A syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months.

About the F33 Code Range
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.
