Poisoning by iminostilbenes, assault, subsequent encounter

This code signifies a harmful reaction to iminostilbene medications, such as carbamazepine or oxcarbazepine, resulting from an intentional act of violence by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the poisoning after the initial treatment has been provided. This could involve managing ongoing symptoms, monitoring for complications, or addressing long-term effects.

This code is appropriate when documenting follow-up care for a patient who was deliberately poisoned with an iminostilbene by another individual. This includes situations where the patient is seen for continued monitoring of drug levels, management of persistent neurological or systemic side effects, or psychological support related to the assault. It should be used after the initial acute phase of treatment has concluded.

• Always ensure documentation clearly specifies the intent as "assault" and that the encounter is for follow-up care.
• Pair this code with external cause codes (e.g., Y07.-) to fully describe the circumstances of the assault.
• Do not use this code for accidental poisonings, self-harm, or initial treatment of the acute poisoning.
