Antepartum hemorrhage with coagulation defect, unspecified, third trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Antepartum hemorrhage refers to bleeding that occurs during pregnancy before the onset of labor. When this bleeding is associated with a coagulation defect—meaning the blood's ability to clot properly is impaired—it presents additional risks for both mother and baby. Specifically, code O46.003 addresses cases where this complication occurs in the third trimester with an unspecified coagulation defect, emphasizing the importance of medical monitoring and management to ensure safety.
Causes & Symptoms
Clinical Causes: Coagulation disorders such as thrombocytopenia or clotting factor deficiencies Pre-existing conditions like hemophilia or von Willebrand disease Pregnancy-induced changes affecting blood clotting mechanisms Disseminated intravascular coagulation (DIC), potentially triggered by placental abruption or other pregnancy complications Medications that interfere with clotting processes Infections or systemic conditions impacting blood clotting
Key Symptoms: Visible bleeding from the vagina during pregnancy Abdominal pain or tenderness Contractions or signs of preterm labor Fatigue or unexplained weakness Signs of anemia such as dizziness or pallor Potential swelling or unusual sensations in the abdomen
Diagnostic & Treatment
Diagnosis Path: - Additional tests for underlying coagulation disorders if indicated
Treatment Protocols: - Planning for early delivery if maternal or fetal risk becomes critical, often via cesarean section if necessary
