Antepartum hemorrhage w oth coag defect, first trimester

This code signifies bleeding from the uterus or vagina occurring during the first trimester of pregnancy, specifically when an underlying coagulation defect is identified as a contributing factor. The hemorrhage is antepartum, meaning it occurs before the delivery of the fetus.

Apply this code when documentation clearly indicates a first-trimester antepartum hemorrhage and a co-existing, diagnosed coagulation disorder (e.g., von Willebrand disease, thrombocytopenia, or other clotting factor deficiencies) is implicated in the bleeding. Documentation should specify the trimester and the presence of a coagulation defect.

• Ensure the documentation explicitly states "first trimester" for the hemorrhage.
• Verify that a specific coagulation defect is diagnosed and linked to the bleeding, not just general bleeding.
• Do not use for hemorrhage due to placental abnormalities or other specified causes; those have their own distinct codes.
