Poisoning by butyrophen/thiothixen neuroleptc, assault, init

This code signifies an intentional poisoning with specific types of antipsychotic medications, namely butyrophenones or thiothixenes, where the patient was the victim of an assault. The "initial encounter" indicates that this code is used for the first time the patient is receiving active treatment for this poisoning.

Apply this code when a patient presents with symptoms of acute poisoning due to butyrophenone or thiothixene neuroleptics, and medical documentation clearly states the poisoning was a result of an assault. This would be used for the initial hospital visit or emergency department encounter where the poisoning is first diagnosed and treated.

• Always verify documentation explicitly states "assault" as the intent of the poisoning.
• Ensure the specific neuroleptic agents involved are butyrophenones or thiothixenes.
• Confirm this is the patient's first time receiving treatment for this specific poisoning event.
