Poisoning by thrombolytic drug, accidental, init

This code signifies an adverse event resulting from the unintentional ingestion or administration of a thrombolytic medication, leading to toxic effects. It indicates that the patient is receiving active treatment for the poisoning.

Apply this code when a patient presents with symptoms of poisoning due to an accidental overdose or misadministration of a thrombolytic agent, such as streptokinase or alteplase. This is appropriate for the initial encounter where diagnosis and treatment for the poisoning are being established.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., hemorrhage, coagulopathy).
• Distinguish carefully between accidental poisoning (T45.611-) and therapeutic adverse effects (T45.62-).
• The "A" seventh character indicates an initial encounter for active treatment of the poisoning.
