Code Description

ICD-10 F33.0 is a billable code used to indicate a diagnosis of major depressive disorder, recurrent, mild.

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 at least one episode occurring after a previous episode has resolved. In the case of mild MDD, the symptoms are less severe and may include feelings of sadness, low energy, and difficulty concentrating, but do not significantly impair daily functioning. Patients may experience changes in appetite or sleep patterns, but these changes are not as pronounced as in moderate or severe cases. The diagnosis requires a thorough clinical assessment, including a detailed history of mood changes, duration of symptoms, and impact on daily life. It is essential to differentiate mild MDD from other mood disorders, such as bipolar disorder, where mood episodes can include mania or hypomania. Treatment often involves psychotherapy, lifestyle modifications, and, in some cases, pharmacotherapy with mood stabilizers or antidepressants. Regular suicide risk assessments are crucial, as individuals with recurrent depression may have an increased risk of suicidal ideation or attempts.
