Poisn by slctv seroton/norepineph reup inhibtr, acc, subs

This code signifies an accidental overdose or adverse reaction to selective serotonin and norepinephrine reuptake inhibitors (SNRIs) during a subsequent encounter for treatment. It indicates that the patient is receiving follow-up care for an unintentional poisoning event involving this specific class of antidepressant medication.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of complications arising from an accidental SNRI poisoning. This includes follow-up appointments after initial emergency treatment, or when addressing lingering side effects or organ damage caused by the overdose.

• Ensure documentation clearly states the poisoning was accidental and involves an SNRI.
• Confirm this is a subsequent encounter, not the initial treatment for the poisoning.
• Always code additional diagnoses for specific manifestations of the poisoning (e.g., cardiac arrhythmias, seizures).
