Poisoning by antithrombotic drugs, assault, init encntr

This code signifies an intentional overdose or harmful administration of antithrombotic medications, such as anticoagulants or antiplatelet drugs, by another person with the intent to cause harm. The patient is experiencing the acute effects of this poisoning.

Apply this code when a patient presents with symptoms of antithrombotic toxicity, and the medical record clearly documents that the poisoning was due to an assault. This includes situations where a third party deliberately administered an excessive dose or an inappropriate antithrombotic agent.

• Ensure documentation explicitly states "assault" as the intent of the poisoning.
• Always sequence this code first, followed by codes for specific manifestations of the poisoning.
• An external cause code (e.g., Y09) should also be reported to fully describe the circumstances of the assault.
