Toxic effect of methanol, assault, initial encounter

This code signifies a patient presenting with adverse health effects resulting from methanol poisoning, where the exposure was intentionally inflicted by another person. The "initial encounter" indicates that the patient is receiving active treatment for the acute toxic effects of the methanol.

Apply this code when documenting a patient admitted to the emergency department or hospital for treatment of methanol toxicity, and the medical record clearly states the poisoning was due to an assault. This would include cases where methanol was forcibly administered or covertly given with malicious intent.

• Ensure documentation explicitly states "assault" as the cause of methanol exposure.
• Verify that this is the first time the patient is being seen for this specific methanol poisoning event.
• Always code additional signs and symptoms of methanol toxicity (e.g., metabolic acidosis, visual disturbances) to provide a complete clinical picture.
