Poisoning by iminostilbenes, undetermined, initial encounter

This code signifies an adverse event resulting from exposure to iminostilbene compounds, such as carbamazepine, where the intent of the poisoning is not known or cannot be determined. This could involve an accidental overdose, an intentional but unconfirmed self-harm attempt, or an assault. The "initial encounter" indicates that the patient is receiving active treatment for the poisoning.

Use this code when a patient presents with symptoms of iminostilbene toxicity, and the medical record does not clearly specify whether the poisoning was accidental, intentional self-harm, or an assault. This is appropriate for the first time the patient is seen for this specific poisoning event.

• Always sequence this code first if it is the primary reason for the encounter.
• Do not use this code if the intent (accidental, intentional self-harm, or assault) is clearly documented; instead, choose the appropriate intent-specific code.
• Ensure documentation supports the "initial encounter" designation, meaning the patient is still actively being treated for the poisoning.
