Complete placenta previa NOS or without hemor, second tri

This code signifies a complete placenta previa, meaning the placenta fully covers the internal cervical os, identified during the second trimester of pregnancy. It specifically applies when there is no documented hemorrhage associated with this condition at the time of encounter.

Use this code when the medical record clearly states a diagnosis of complete placenta previa, without any mention of bleeding, and the gestational age is between 14 weeks 0 days and 27 weeks 6 days. Documentation should confirm the placental position relative to the cervical os via ultrasound or other imaging.

• Do not use this code if hemorrhage is present; instead, select a code from O44.1- or O44.2- based on the type of placenta previa and trimester.
• Ensure the trimester is accurately documented; this code is specific to the second trimester.
• If the type of placenta previa (e.g., complete, partial, marginal) is not specified but documented as "placenta previa NOS," this code is appropriate for the second trimester without hemorrhage.
