Poisoning by antiallerg/antiemetic, assault, sequela

This code signifies a long-term health problem or complication arising from a deliberate act of poisoning with antiallergic or antiemetic medications. The initial poisoning event was an assault, meaning the drug was administered by another person with harmful intent. The sequela could manifest as chronic organ damage, neurological deficits, or persistent psychiatric issues.

Use this code when documenting a patient's current condition that is a direct, lasting consequence of a past poisoning by antiallergic or antiemetic drugs, where the poisoning was determined to be an assault. This applies to follow-up visits for chronic conditions directly attributable to the assaultive poisoning, even if the acute phase has resolved.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., chronic liver failure).
• Ensure documentation clearly links the current condition to the past assaultive poisoning by antiallergic/antiemetic drugs.
• Do not use for acute poisoning events; this code is exclusively for residual effects or complications.
