Toxic effect of nitrogen oxides, assault, initial encounter

This code signifies a harmful reaction to nitrogen oxides resulting from an intentional act of violence or aggression. It specifically applies when the patient is experiencing the acute effects of the exposure.

Apply this code when documenting a patient presenting with symptoms such as respiratory distress, chemical burns, or other systemic effects due to deliberate exposure to nitrogen oxides. This is appropriate for initial treatment following an assault.

• Ensure documentation clearly states the exposure was due to an assault.
• Confirm this is the first encounter for treatment of this specific toxic effect.
• Do not use for accidental or unintentional exposures; those require different codes.
