Code Description

ICD-10 F33.1 is a billable code used to indicate a diagnosis of major depressive disorder, recurrent, moderate.

Key Diagnostic Point:

Major depressive disorder (MDD) is characterized by recurrent episodes of depression that significantly impair an individual's ability to function. The recurrent nature of this disorder indicates that the patient has experienced multiple episodes of depression, with each episode lasting at least two weeks. The moderate classification suggests that the symptoms are more severe than mild depression but do not meet the criteria for severe depression. Symptoms may include persistent sadness, loss of interest in previously enjoyed activities, changes in appetite or weight, sleep disturbances, fatigue, feelings of worthlessness or excessive guilt, and difficulty concentrating. The diagnosis requires a thorough clinical assessment, including a detailed history of mood changes and functional impairment. Treatment often involves a combination of psychotherapy and pharmacotherapy, including mood stabilizers and antidepressants. Given the recurrent nature of the disorder, ongoing management and monitoring are essential to prevent relapse and address any potential suicide risk, which is notably higher in individuals with recurrent depression.
