Toxic effect of smoke, assault, initial encounter

This code signifies a harmful physiological response resulting from exposure to smoke, specifically when the exposure is due to an intentional act of violence or aggression by another person. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of this toxic exposure.

Apply this code when a patient presents with symptoms such as respiratory distress, carbon monoxide poisoning, or other systemic effects directly attributable to smoke inhalation, and the medical record clearly documents that the smoke exposure was a deliberate assault. This would include scenarios like arson where the patient was intentionally trapped in a burning structure or exposed to smoke as a weapon.

• Ensure documentation explicitly states the smoke exposure was an assault, not accidental or self-inflicted.
• Always sequence this code first if it is the primary reason for the encounter.
• Code any associated injuries or conditions resulting from the assault (e.g., burns, anoxia) with additional codes.
