Code Description

ICD-10 F33 is a billable code used to indicate a diagnosis of major depressive disorder, recurrent.

Key Diagnostic Point:

Major depressive disorder, recurrent (F33) is characterized by the presence of multiple episodes of major depression, which can significantly impair an individual's ability to function in daily life. Each episode is marked by a persistent low mood, loss of interest or pleasure in activities, changes in appetite or weight, sleep disturbances, fatigue, feelings of worthlessness or excessive guilt, and recurrent thoughts of death or suicide. The recurrent nature of this disorder distinguishes it from a single episode of major depression, as individuals may experience multiple episodes throughout their lifetime, often with varying severity and duration. The diagnosis requires careful assessment of the patient's history, including the frequency and duration of depressive episodes, as well as any associated psychosocial stressors. Treatment typically involves a combination of psychotherapy and pharmacotherapy, including mood stabilizers and antidepressants. Given the high risk of suicide associated with recurrent major depressive disorder, thorough risk assessment and ongoing monitoring are critical components of care.
