Prem separtn of placenta w dissem intravasc coag, third tri

This code signifies the premature detachment of the placenta from the uterine wall, occurring specifically during the third trimester of pregnancy, and complicated by disseminated intravascular coagulation (DIC). This life-threatening obstetric emergency involves widespread activation of the clotting cascade, leading to both thrombosis and hemorrhage.

Apply this code when documentation clearly indicates a diagnosis of placental abruption in a patient in her third trimester, and there is explicit mention of co-occurring disseminated intravascular coagulation. This typically involves laboratory evidence of DIC (e.g., decreased platelets, prolonged PT/aPTT, elevated D-dimer) in addition to clinical signs of abruption.

• Ensure the documentation specifies "third trimester" for the abruption.
• Confirm the presence of DIC; do not assume it based solely on severe abruption.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter.
