Toxic effect of carbon dioxide, assault, initial encounter

This code signifies the adverse health effects resulting from exposure to carbon dioxide due to an intentional act of harm. The patient is in the acute phase of treatment for the poisoning.

Apply this code when documenting a patient presenting with symptoms of carbon dioxide toxicity, such as headache, dizziness, nausea, or loss of consciousness, where the exposure was deliberately inflicted by another party. This is appropriate for the initial hospital visit or emergency department encounter for such an event.

• Ensure documentation clearly states the poisoning was an assault.
• Confirm this is the first encounter for this specific poisoning event.
• Code any associated injuries or conditions separately.
