Poisoning by hemostatic drug, accidental, init

This code signifies an unintended adverse event resulting from the ingestion or exposure to a hemostatic drug. This typically involves an overdose or an unexpected reaction to a medication designed to promote blood clotting, occurring through an accidental mechanism. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific poisoning.

Use this code when a patient presents to an emergency department or clinic with symptoms of poisoning due to an accidental overdose of a hemostatic agent, such as vitamin K, desmopressin, or antifibrinolytics. This applies when the intent of the poisoning is clearly documented as unintentional, for example, due to a medication error, misidentification of the drug, or accidental ingestion by a child.

• Always confirm the intent of the poisoning is "accidental (unintentional)" as specified by the code.
• Assign an additional code for the specific hemostatic drug involved, if known and documented.
• Ensure the "initial encounter" character is appropriate for the patient's current treatment phase.
