Major depressive disorder, single episode, unspecified

This code signifies a patient experiencing a single episode of major depression without further specification regarding severity or psychotic features. It indicates a significant depressive mood or anhedonia, accompanied by other depressive symptoms, that has not been previously diagnosed as recurrent.

Use this code when documentation clearly states a diagnosis of major depressive disorder, single episode, but lacks details on severity (e.g., mild, moderate, severe) or the presence of psychotic symptoms. It is appropriate for initial diagnoses where further clinical assessment is pending or when the specific severity is not determined.

• Only use this code when the documentation explicitly states "unspecified" or provides no further detail on severity or psychotic features.
• Prioritize more specific codes (e.g., F32.0-F32.3) if the documentation allows for greater specificity regarding severity or psychotic features.
• Ensure the medical record supports a single episode, not a recurrent one, to differentiate from codes in the F33 category.
