Poisoning by unsp antipsychot/neurolept, undetermined, init

This code indicates a case of poisoning due to an antipsychotic or neuroleptic medication where the specific drug involved is unknown. The intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. This is the initial encounter for the patient's treatment of this poisoning.

Use this code when a patient presents with symptoms of antipsychotic or neuroleptic toxicity, but the exact substance is not identified in the medical record. It is appropriate when the physician cannot ascertain whether the poisoning was accidental, intentional, or due to an assault. This code is only for the first time the patient is seen for this specific poisoning event.

• Requires documentation explicitly stating "unspecified" antipsychotic/neuroleptic and "undetermined" intent.
• Ensure the "A" suffix for initial encounter is appropriate; subsequent encounters would use "D" or "S".
• Avoid using this code if the specific drug or intent can be clarified through further investigation or documentation.
