Poisoning by thrombolytic drug, undetermined, subs encntr

This code signifies an adverse event where a patient has been poisoned by a thrombolytic medication, and the intent (accidental, intentional self-harm, assault) cannot be determined. It indicates that the patient is receiving active treatment for the poisoning, or the sequelae of the poisoning, after the initial encounter.

Apply this code when a patient presents for follow-up care, monitoring, or continued treatment of a thrombolytic drug poisoning where the circumstances of the poisoning are unknown. This is appropriate for subsequent visits after the initial emergency or acute care for the poisoning has been rendered.

• Always use in conjunction with an external cause code (V00-Y99) to provide more detail about the event, even if the intent is undetermined.
• Ensure documentation clearly supports that this is a "subsequent encounter" and not the initial treatment phase.
• Verify the specific thrombolytic agent involved if possible, though this code is for a general class.
