Partial placenta previa NOS or without hemor, second tri

This code signifies a condition where the placenta partially covers the internal cervical os during the second trimester of pregnancy, without specifying a cause or the presence of active bleeding. It indicates an abnormal placental implantation that may resolve as the uterus grows.

Apply this code when documentation confirms a diagnosis of partial placenta previa identified during the second trimester, and there is no mention of hemorrhage or a more specific type of placenta previa. This is typically supported by ultrasound findings.

• Do not use this code if hemorrhage is documented; instead, select a code from O44.0- or O44.1-.
• Ensure the trimester is clearly documented as the second trimester.
• Distinguish from complete placenta previa (O44.20) or marginal placenta previa (O44.23).
