Partial placenta previa NOS or without hemor, third tri

This code signifies a condition where the placenta partially covers the internal cervical os during the third trimester of pregnancy, without any documented bleeding. It indicates a diagnosis of partial placenta previa that is not further specified as to type or is explicitly stated to be without hemorrhage.

Use this code when the physician documents "partial placenta previa" or "placenta previa, not otherwise specified" in a patient in her third trimester, and there is no mention of hemorrhage. It is appropriate when the documentation confirms the placental position but explicitly states the absence of bleeding or does not specify the presence of bleeding.

• Ensure the documentation explicitly states "partial" or "NOS" and confirms the third trimester.
• Do not use this code if any hemorrhage is documented; instead, select a code that specifies hemorrhage.
• Distinguish from complete or marginal placenta previa; this code is specific to partial or unspecified types.
