Prem separtn of placenta w oth coag defect, second trimester

This code signifies a placental abruption occurring during the second trimester of pregnancy, specifically when a pre-existing or acquired coagulation defect, other than disseminated intravascular coagulation (DIC), is also present. This condition involves the premature detachment of the placenta from the uterine wall, leading to potential maternal hemorrhage and fetal distress.

Apply this code when documentation clearly indicates a diagnosis of placental abruption in the second trimester, alongside a specified coagulation disorder (e.g., hemophilia, von Willebrand disease, or other inherited/acquired clotting factor deficiencies) that is not DIC. The medical record should explicitly link the abruption to the presence of this other coagulation defect.

• Ensure the documentation specifies "second trimester" and identifies a coagulation defect other than DIC.
• Do not use this code if the coagulation defect is DIC; refer to O45.01- codes.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter.
