Suicide and self-inflicted injury by submersion [drowning]

This code signifies a fatal or non-fatal self-inflicted injury resulting from submersion in water or other liquid, with the explicit intent to end one's life. It describes the act of drowning as a method of suicide.

Apply this code when documentation clearly states a patient attempted or completed suicide by intentionally submerging themselves. This includes cases where the patient was rescued but suffered injury (e.g., anoxic brain injury, aspiration pneumonia) or when the act resulted in death.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Distinguish carefully from accidental drowning (E910.0-E910.9) or assault by drowning (E964.0).
• Look for explicit statements of suicidal intent or a history of self-harm to support this code.
