Poisoning by thrombolytic drug, assault, initial encounter

This code signifies a deliberate act of harm where a thrombolytic agent, such as tissue plasminogen activator (tPA) or streptokinase, is administered to an individual with the intent to injure or kill. This results in a toxic effect from the drug. The "initial encounter" indicates the patient is receiving active treatment for the poisoning.

Apply this code when documentation clearly states a patient has been poisoned by a thrombolytic drug due to an assault. This would include cases where the drug was forcibly administered or given without the patient's knowledge or consent with malicious intent. It is used for the initial hospitalization or encounter for treatment of the acute poisoning.

• Always sequence this code first as the primary diagnosis when it represents the reason for the encounter.
• Requires an external cause code (e.g., Y07.0-Y07.9) to specify the perpetrator and circumstances of the assault.
• Do not use for accidental overdose or therapeutic misadventure; different codes apply for those scenarios.
