Poisoning by antithrombotic drugs, assault, subs encntr

This code indicates a patient presenting for follow-up care or treatment of adverse effects resulting from an intentional overdose or malicious administration of an antithrombotic medication by another party. The poisoning has already occurred, and the patient is no longer in the initial acute phase of treatment.

Use this code for subsequent encounters where a patient is receiving ongoing management, monitoring, or rehabilitation for complications arising from an antithrombotic drug poisoning that was determined to be an assault. Examples include follow-up appointments for coagulopathy, organ damage, or psychological support related to the event.

• Always assign an additional code for the specific antithrombotic drug involved, if known.
• Ensure documentation clearly specifies "assault" and that this is a "subsequent encounter" for the poisoning.
• Do not use for initial acute treatment or for accidental or self-inflicted poisonings.
