Poisoning by oth antipsychot/neurolept, self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of antipsychotic or neuroleptic medications, excluding phenothiazine-based drugs. The intent of this ingestion was to cause self-harm, and this encounter represents the initial presentation for treatment.

Apply this code when documentation clearly indicates an overdose or toxic reaction to a non-phenothiazine antipsychotic, such as olanzapine, risperidone, or quetiapine, with explicit intent of self-harm. This is appropriate for the emergency department visit or initial inpatient admission for managing the acute poisoning.

• Always verify the specific type of antipsychotic involved to ensure it's not a phenothiazine (which has a separate code).
• Confirm the intent of self-harm is clearly documented; otherwise, an accidental poisoning code would be more appropriate.
• Remember to also code any associated mental health diagnoses, such as major depressive disorder or suicidal ideation.
