Poisoning by antithrombotic drugs, self-harm, subs

This code signifies a patient presenting for follow-up care related to an intentional overdose of an antithrombotic medication. This includes subsequent evaluations, monitoring for ongoing effects, or management of complications arising from the self-harm attempt. The initial acute phase of the poisoning has passed.

Use this code for patients returning for ongoing treatment or assessment after being discharged from an acute care setting following an intentional antithrombotic overdose. This applies to encounters for managing residual symptoms, monitoring coagulation parameters, or addressing psychological sequelae. It is appropriate for any encounter after the initial treatment of the acute poisoning.

• Always assign an additional code for the specific antithrombotic drug if known.
• Ensure the "D" seventh character is appropriate for a subsequent encounter, not initial or sequela.
• Consider co-reporting with codes for mental health conditions related to the self-harm attempt.
