Toxic effect of nitrogen oxides, intentional self-harm, init

This code signifies a patient presenting with adverse health effects resulting from deliberate self-exposure to nitrogen oxides. These effects can range from respiratory distress to more severe systemic toxicity, intentionally inflicted by the patient.

This code is appropriate for initial encounters where a patient has intentionally inhaled or otherwise exposed themselves to nitrogen oxides with the intent to cause self-harm. This includes cases of attempted suicide or deliberate self-poisoning using substances containing nitrogen oxides.

• Always confirm the intent was self-harm; otherwise, a different "toxic effect" code would be more appropriate.
• Ensure this is the initial encounter for this specific toxic event; subsequent care would use a different seventh character.
• Document the specific nitrogen oxide involved if known, though this code covers the general category.
