Poisoning by oth antipsychot/neurolept, assault, sequela

This code signifies a long-term health consequence resulting from an intentional overdose or harmful exposure to antipsychotic medications or neuroleptics. The poisoning was inflicted by another party with intent to harm. The patient is no longer in the acute phase of the poisoning but is experiencing residual effects.

Apply this code when documenting a patient presenting with chronic or residual symptoms (e.g., tardive dyskinesia, persistent neurological deficits, organ damage) directly attributable to a past assault involving antipsychotic or neuroleptic substances. This code is appropriate for follow-up care after the initial acute poisoning event has resolved.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly states the poisoning was an assault and that the patient is experiencing a sequela.
• Do not use for acute poisoning events; refer to appropriate acute poisoning codes.
