Antepartum hemorrhage w oth coag defect, third trimester

This code signifies bleeding from the vagina during the third trimester of pregnancy, specifically when the hemorrhage is associated with an underlying disorder of the blood clotting system. This coagulation defect is not specified as disseminated intravascular coagulation (DIC) or hyperfibrinolysis.

Apply this code when a pregnant patient in her third trimester presents with antepartum bleeding and medical records confirm a pre-existing or newly diagnosed coagulation defect, excluding DIC or hyperfibrinolysis. Documentation should clearly state the trimester and the presence of both hemorrhage and the specific type of coagulation abnormality.

• Ensure documentation specifies "third trimester" and a coagulation defect other than DIC or hyperfibrinolysis.
• Do not use this code if the hemorrhage is due to placenta previa, abruptio placentae, or vasa previa; specific codes exist for those conditions.
• Sequence this code as a primary diagnosis when the antepartum hemorrhage is the reason for the encounter, followed by codes for the specific coagulation defect.
