What This Code Means

A first-time episode of major depression with mild symptoms that significantly impact daily functioning but are not severe.

Coding Tips

  • Single episode means this is the patient's first major depressive episode; confirm no prior episodes
  • Mild severity requires documentation of functional impairment but without severe symptoms like psychosis

Clinical Significance

Major depressive disorder, single episode, mild represents a first-time major depressive episode with minimal functional impairment. While mild, this diagnosis establishes a psychiatric history that is important for longitudinal care planning. Single episode designation indicates no prior history of major depressive episodes, which has prognostic implications for recurrence risk.

Documentation Requirements

  • Provider documentation of major depressive disorder (not simply 'depression' or 'depressed mood')
  • First (single) episode explicitly stated or confirmed through history review
  • Severity documented as mild with minimal functional impairment
  • Core depressive symptoms documented (depressed mood, anhedonia, plus supporting criteria)
  • Duration of at least 2 weeks
  • Treatment plan including therapy, medication, or both
