Poisoning by hemostatic drug, undetermined, subs encntr

This code signifies a patient presenting with adverse effects from a hemostatic medication, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is in the recovery phase or receiving ongoing treatment for the poisoning, not the initial acute presentation.

Apply this code when a patient is seen for follow-up care, monitoring, or treatment of complications arising from an undetermined poisoning by a drug used to promote blood clotting. This includes scenarios where the initial acute event has passed, but the patient requires continued medical attention related to the toxic exposure.

• Always assign an additional code for the specific hemostatic drug if known.
• Ensure the "D" seventh character is appropriate for subsequent encounters, indicating ongoing care after the initial treatment.
• Distinguish from initial encounters ("A") or sequelae ("S") based on the patient's current phase of care.
