Poisoning by antiallerg/antiemetic, assault, subs

This code signifies a patient presenting with adverse effects or toxicity resulting from the intentional administration of antiallergic or antiemetic medications by another person with harmful intent. The patient is in the recovery phase, receiving follow-up care, or experiencing residual effects from the initial poisoning event.

Use this code for subsequent encounters when a patient is being treated for complications, sequelae, or ongoing management related to a previous poisoning by antiallergic or antiemetic drugs that occurred as an assault. This includes follow-up visits for organ damage, neurological deficits, or other long-term effects stemming from the initial event.

• Always sequence this code after the primary diagnosis indicating the specific manifestation of the poisoning.
• Ensure documentation clearly specifies the "assault" intent and that the encounter is "subsequent" to the initial poisoning.
• Do not use for initial encounters or for accidental or self-harm poisonings.
