Poisn by slctv seroton/norepineph reup inhibtr, undet, sqla

This code signifies the long-term effects or complications arising from an undetermined poisoning event involving selective serotonin and norepinephrine reuptake inhibitors (SNRIs). These sequelae can manifest as persistent neurological, cardiovascular, or psychiatric issues that are directly attributable to the past SNRI exposure. The "undetermined" nature indicates that the intent of the poisoning (e.g., accidental, intentional self-harm, assault) could not be definitively established.

Apply this code when a patient presents with a current condition or symptom that is a residual effect of a past SNRI poisoning, and the intent of that poisoning was not determined at the time of the original event. This is typically used in follow-up encounters long after the acute poisoning has been treated, to document ongoing health problems linked to the exposure.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease, persistent arrhythmia).
• Ensure documentation clearly links the current condition to a past SNRI poisoning with undetermined intent.
• Do not use this code for acute poisoning events; it is exclusively for sequelae.
