Antepartum hemorrhage with afibrinogenemia, second trimester

This code signifies bleeding from the uterus or birth canal occurring during the second trimester of pregnancy (weeks 14 through 27+6 days), specifically when complicated by afibrinogenemia. Afibrinogenemia is a rare, severe coagulation disorder characterized by the absence of fibrinogen, a crucial protein for blood clotting. This combination presents a high risk of severe maternal hemorrhage.

Apply this code when documentation clearly indicates antepartum hemorrhage occurring in the second trimester, and laboratory findings or clinical assessment confirm the presence of afibrinogenemia. This would typically be seen in cases of placental abruption, placenta previa, or other causes of bleeding in a patient with a known or newly diagnosed fibrinogen deficiency. Documentation should specify the trimester and the coagulation disorder.

• Ensure documentation explicitly states "second trimester" for the hemorrhage.
• Verify that afibrinogenemia is clearly diagnosed and linked to the antepartum hemorrhage.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter, followed by codes for the specific cause of the hemorrhage (e.g., placental abruption) if known.
