Prem separtn of placenta w coag defect, unsp, second tri

This code signifies an abruptio placentae occurring during the second trimester of pregnancy, where the premature separation of the placenta from the uterine wall is complicated by an unspecific coagulation disorder. This condition can lead to significant maternal hemorrhage and fetal distress.

Apply this code when documentation clearly indicates a diagnosis of placental abruption in the second trimester, and there is an associated, but unspecified, coagulation defect. This typically includes cases where abnormal bleeding or clotting is noted in conjunction with the abruption, but the specific type of coagulopathy is not yet identified.

• Ensure the documentation explicitly states "second trimester" for accurate trimester assignment.
• Do not use this code if a specific coagulation defect (e.g., disseminated intravascular coagulation) is identified; instead, code the specific defect.
• Always sequence this code as the principal diagnosis when it is the reason for the encounter, followed by codes for any associated complications.
