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

This code signifies a patient presenting with adverse effects from an unspecified antipsychotic or neuroleptic medication, where the ingestion was deliberately self-inflicted. The patient is in the initial phase of treatment for this poisoning event.

Apply this code when documentation clearly indicates an intentional overdose or self-poisoning attempt involving an antipsychotic or neuroleptic drug, and the specific drug is not identified. This is appropriate for the initial hospital visit or encounter where the poisoning is first evaluated and treated.

• Ensure documentation explicitly states "intentional self-harm" or similar language to support the intent.
• Only use this code for the initial encounter; subsequent encounters will require a different seventh character.
• Avoid using this code if the specific antipsychotic or neuroleptic agent is known; instead, code to the specific drug.
