ICD-10: T45.511

The ICD-10 code T45.511 refers to "Poisoning by anticoagulants, accidental (unintentional)." This classification is crucial for healthcare providers to accurately document and manage cases of unintentional anticoagulant poisoning. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Overview of Anticoagulants

Anticoagulants are medications that prevent blood clotting and are commonly prescribed for conditions such as atrial fibrillation, deep vein thrombosis, and pulmonary embolism. Common anticoagulants include warfarin, rivaroxaban, apixaban, and heparin. Accidental poisoning can occur due to medication errors, overdoses, or ingestion of anticoagulants not prescribed to the patient.

Signs and Symptoms

The clinical presentation of accidental anticoagulant poisoning can vary based on the specific anticoagulant involved, the dose ingested, and the time elapsed since ingestion. Common signs and symptoms include:

• Bleeding: The most significant and dangerous symptom, which can manifest as:
• Gastrointestinal bleeding: Hematemesis (vomiting blood) or melena (black, tarry stools).
• Intracranial hemorrhage: Symptoms may include severe headache, confusion, or loss of consciousness.
• Subcutaneous bleeding: Bruising or petechiae (small red or purple spots on the skin).

• Hematuria: Blood in urine.

• Hypotension: Low blood pressure due to significant blood loss.

• Tachycardia: Increased heart rate as a compensatory mechanism in response to bleeding.

• Dizziness or Syncope: Lightheadedness or fainting due to reduced blood volume.

• Altered Mental Status: Confusion or decreased responsiveness, particularly in cases of severe bleeding or intracranial involvement.

Patient Characteristics

Certain patient characteristics may predispose individuals to accidental anticoagulant poisoning:

• Age: Elderly patients are at higher risk due to polypharmacy and potential cognitive decline, which may lead to medication errors.

• Cognitive Impairment: Patients with dementia or other cognitive impairments may inadvertently take incorrect dosages or medications.

• Chronic Conditions: Individuals with multiple chronic conditions may be on various medications, increasing the risk of drug interactions and errors.

• Recent Changes in Medication: Patients who have recently started or changed anticoagulant therapy may be at risk if they are not adequately monitored or educated about their medication.
