Poisoning by oth antipsychot/neurolept, undetermined, init

This code indicates a poisoning event involving antipsychotic or neuroleptic medications other than phenothiazine-based drugs, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the initial phase of treatment for this poisoning.

Apply this code when a patient presents with adverse effects from an antipsychotic or neuroleptic drug (excluding phenothiazines), and the clinician cannot ascertain if the exposure was accidental, intentional, or due to assault. This is for the first encounter related to this specific poisoning episode.

• Always sequence this code first for poisoning cases, followed by codes for all manifestations of the poisoning.
• Ensure documentation clearly states "undetermined" intent for the poisoning.
• Do not use this code if the intent of the poisoning is known (e.g., accidental, intentional self-harm).
