Poisoning by antithrombotic drugs, self-harm, sequela

This code signifies long-term effects or complications arising from an intentional overdose or self-poisoning with antithrombotic medications. These sequelae are the residual conditions that persist after the acute phase of the poisoning has resolved. Examples include chronic organ damage, neurological deficits, or persistent coagulopathies directly attributable to the past self-harm event.

Apply this code when documenting conditions that are a direct consequence of a past intentional self-harm event involving antithrombotic drugs, and these conditions are still present or being treated. This is appropriate for follow-up visits or admissions where the focus is on managing these chronic complications, not the acute poisoning itself.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional antithrombotic poisoning.
• Do not use this code for the initial acute poisoning event; use the acute poisoning code with the appropriate seventh character for initial encounter.
