In simple words: The placenta is covering the opening of the womb completely, but there's no bleeding at this time. This is known as a complete placenta previa.

Complete placenta previa without hemorrhage.The placenta completely obstructs the cervical os, but there is no active bleeding.It includes cases where the placenta is implanted low in the uterus without causing hemorrhage.

Example 1: A pregnant woman in her third trimester undergoes a routine ultrasound that reveals the placenta completely covering the cervical opening. She reports no vaginal bleeding.The diagnosis of complete placenta previa without hemorrhage (O44.0) is made., A woman at 20 weeks gestation presents for a prenatal checkup.An ultrasound shows a low-lying placenta, which is documented as complete placenta previa, however, the patient does not exhibit signs of hemorrhage, hence coded as O44.0. Repeat ultrasound at 28 weeks reveals that the placenta has migrated away from the cervix. Regular prenatal visits continue., A pregnant woman at 30 weeks gestation experiences painless vaginal bleeding.An ultrasound demonstrates complete placenta previa. While she has a history of bleeding, she is currently not hemorrhaging; therefore, O44.0 is appropriate until active bleeding recurs.She is admitted for observation and monitoring.

Documentation should include ultrasound findings confirming the complete covering of the cervical os by the placenta. Absence of active bleeding should also be documented explicitly.The estimated gestational age and details of any prior bleeding episodes should be noted.
