Poisoning by antithrombotic drugs, assault, sequela

This code signifies a long-term consequence or complication arising from an intentional act of poisoning with an antithrombotic drug. The initial poisoning event was an assault, and the patient is now presenting with a residual condition directly attributable to that past event.

Use this code when documenting a chronic or residual health problem that is a direct result of a previous antithrombotic drug poisoning, where the poisoning was determined to be an assault. This applies to follow-up encounters for conditions like persistent coagulopathy, organ damage, or neurological deficits stemming from the original event.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past antithrombotic drug poisoning that was an assault.
• Do not use for acute poisoning events; this code is specifically for sequelae.
