Poisn by slctv seroton/norepineph reup inhibtr,slf-hrm, init

This code signifies a deliberate act of self-poisoning using a selective serotonin and norepinephrine reuptake inhibitor (SSNRI). The patient has intentionally ingested an excessive amount of this antidepressant medication with the intent to cause harm to themselves. This is the first time the patient is being treated for this specific poisoning event.

Apply this code when a patient presents to an emergency department or other healthcare setting following an intentional overdose of an SSNRI. This includes situations where the patient admits to self-harm, or when clinical evidence strongly suggests a deliberate act. It is used for the initial treatment encounter related to this specific poisoning.

• Always confirm the intent of self-harm versus accidental or therapeutic misadventure.
• Ensure the specific drug involved is an SSNRI; if not, a different poisoning code is required.
• Pair this code with external cause codes (e.g., X61.0XXA) to fully describe the circumstances of the poisoning.
