Complete placenta previa NOS or without hemor, third tri

This code signifies a complete placenta previa, meaning the placenta fully covers the internal cervical os, identified during the third trimester of pregnancy. This specific code is used when there is no associated hemorrhage documented or when the type of hemorrhage is not otherwise specified.

Apply this code when documentation clearly states "complete placenta previa" in a patient in her third trimester, and there is no mention of bleeding, or the bleeding status is not specified. It is appropriate for routine follow-up or management of an asymptomatic complete previa.

• Differentiate from partial or marginal placenta previa; this code is strictly for complete previa.
• Do not use if hemorrhage is present and specified (e.g., mild, moderate, severe); instead, select a more specific code from the O44.0- or O44.1- series.
• Always sequence this code after the primary obstetric code (e.g., Z3A.xx for weeks of gestation).
