Poisn by selective serotonin reuptake inhibtr, assault, subs

This code signifies an adverse health effect resulting from the intentional administration of a selective serotonin reuptake inhibitor (SSRI) by another person with the intent to harm. The patient is presenting for follow-up care or treatment of sequelae after the initial acute phase of poisoning has been addressed. This could involve ongoing management of symptoms, monitoring for long-term effects, or addressing complications.

Use this code when documenting subsequent encounters for a patient who was poisoned by an SSRI due to an assault. This applies to visits for ongoing treatment, monitoring of organ function, management of persistent neurological or psychiatric symptoms, or addressing complications that arise after the initial presentation. Do not use for the initial acute care visit.

• Ensure documentation clearly states the poisoning was due to an assault and that this is a subsequent encounter.
• Always code additional diagnoses for specific manifestations of the poisoning (e.g., cardiac arrhythmias, seizures, serotonin syndrome).
• Distinguish this from accidental poisoning (T43.221-) or self-harm (T43.222-).
