Antepartum hemorrhage with afibrinogenemia, first trimester

This code signifies bleeding from the uterus during the first trimester of pregnancy, specifically when the mother also presents with afibrinogenemia. Afibrinogenemia is a rare, inherited bleeding disorder characterized by the complete absence of fibrinogen, a crucial protein for blood clotting. This combination poses significant risks to both the mother and the fetus.

Apply this code when documentation clearly indicates a pregnant patient in her first trimester experiencing vaginal bleeding, and laboratory results or a confirmed diagnosis establish the presence of afibrinogenemia. This code is appropriate for cases where the hemorrhage is directly complicated by the coagulation disorder.

• Ensure documentation explicitly states "first trimester" for the pregnancy.
• Verify that afibrinogenemia is confirmed, not just suspected, and linked to the hemorrhage.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter, followed by codes for any associated complications.
