Major depressive disorder, single episode, mild

This code signifies a patient experiencing their first episode of major depression, characterized by a depressed mood or anhedonia, and at least four additional depressive symptoms, lasting for at least two weeks. The "mild" specifier indicates that the symptoms cause only minor functional impairment and are manageable with minimal difficulty.

Apply this code when documentation clearly indicates a patient's initial presentation of major depressive disorder with symptoms meeting diagnostic criteria for a mild severity level. Supporting documentation should include a psychiatric evaluation detailing the number and duration of symptoms, the absence of prior depressive episodes, and the impact on daily functioning.

• Differentiate from recurrent episodes (F33.x) or other specified depressive disorders (F32.8).
• Ensure the documentation explicitly states "single episode" and "mild" severity.
• Always review the full diagnostic criteria for major depressive disorder to confirm appropriate application.
