Antepart hemor w dissem intravasc coag, second trimester

This code signifies bleeding from the uterus or vagina occurring during the second trimester of pregnancy (weeks 14 through 27+6 days), complicated by disseminated intravascular coagulation (DIC). DIC is a serious condition where abnormal blood clotting occurs throughout the body's small blood vessels, leading to both excessive clotting and bleeding.

Apply this code when documentation clearly indicates antepartum hemorrhage in a pregnant patient during her second trimester, and there is a confirmed diagnosis of DIC. This typically involves laboratory findings consistent with DIC (e.g., decreased platelets, prolonged PT/aPTT, elevated D-dimer) alongside clinical signs of bleeding.

• Always confirm the trimester of pregnancy from the medical record.
• Ensure documentation explicitly states "disseminated intravascular coagulation" or provides sufficient clinical and lab findings to support this diagnosis.
• Code any underlying cause of the antepartum hemorrhage (e.g., placenta previa, placental abruption) as an additional diagnosis.
