Poisn by unsp antieplptc and sed-hypntc drugs, slf-hrm, init

This code signifies a patient presenting with adverse effects from an intentional overdose of an antiepileptic or sedative-hypnotic medication, where the specific drug is not documented. The overdose was self-inflicted, indicating a suicide attempt or other deliberate act of self-harm. The "initial encounter" designation means this is the first time the patient is being treated for this specific poisoning event.

This code is appropriate for emergency department visits or initial hospital admissions for patients who have intentionally ingested an unknown antiepileptic or sedative-hypnotic drug with harmful effects. It applies when the specific substance is not identified, but the drug class is known. Use this code when the patient is actively being treated for the acute poisoning.

• Always sequence this code first if it is the primary reason for the encounter.
• Do not use this code if the specific antiepileptic or sedative-hypnotic drug is known; instead, use the more specific code for that substance.
• Remember to also code for any associated mental health conditions, such as depression or suicidal ideation, if documented.
