Asphyxiation due to hanging, undetermined, initial encounter

This code signifies a case of asphyxia resulting from hanging, where the intent (e.g., accidental, suicidal, homicidal) cannot be definitively determined at the time of initial assessment. It indicates a severe lack of oxygen to the body due to strangulation by suspension, with an unknown underlying cause.

Apply this code for patients presenting with signs and symptoms of asphyxiation due to hanging, when medical documentation explicitly states the intent is undetermined. This is appropriate for the initial encounter for treatment of the acute effects of this event.

• Ensure documentation clearly states "undetermined" intent for the hanging.
• Always append the appropriate seventh character for the encounter (A for initial, D for subsequent, S for sequela).
• Do not use this code if the intent (accidental, suicidal, homicidal) is clearly documented; use the more specific code.
