Antepartum hemorrhage w coag defect, unsp, unsp trimester

This code signifies bleeding from the vagina during pregnancy, specifically when a problem with blood clotting is identified as the cause, but the exact trimester and the specific type of coagulation defect are not documented. It indicates an obstetric complication where the mother's blood clotting ability is impaired, leading to antepartum hemorrhage.

Use this code when a pregnant patient presents with vaginal bleeding and laboratory tests or clinical assessment confirm an underlying coagulation defect, but the specific trimester of pregnancy and the precise nature of the clotting disorder are not specified in the medical record. This code is appropriate when more specific information regarding the trimester or the coagulation defect is unavailable or not documented.

• Ensure documentation explicitly states "coagulation defect" as the cause of the hemorrhage.
• Avoid using this code if the trimester or the specific coagulation defect is known; instead, use a more specific O46.0 subcategory.
• Always sequence this code as a principal diagnosis if it is the primary reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
