Poisoning by oth antipsychot/neurolept, accidental, init

This code signifies an accidental overdose or adverse reaction to an antipsychotic or neuroleptic medication not specified elsewhere, resulting in poisoning. It indicates that the event was unintentional and represents the initial phase of treatment for the poisoning.

Apply this code when a patient presents to an emergency department or clinic with symptoms of poisoning due to an accidental ingestion or misadministration of an antipsychotic or neuroleptic drug. This is appropriate for the initial encounter where the poisoning is first diagnosed and managed.

• Always code the specific drug if known, using a more precise T43.5x code if available.
• Ensure documentation clearly states the poisoning was accidental and this is the initial encounter for treatment.
• Remember to also code any associated signs, symptoms, or manifestations of the poisoning.
