Complete placenta previa with hemorrhage, unsp trimester

This code signifies a pregnancy complicated by a complete placenta previa, where the placenta fully covers the internal cervical os, and the patient is experiencing vaginal bleeding. The specific trimester of the pregnancy is not documented or is unknown. This condition carries a significant risk of maternal and fetal morbidity and mortality.

Assign this code when documentation clearly states "complete placenta previa with hemorrhage" and the trimester is not specified. This code is appropriate for initial encounters or when the specific trimester cannot be determined from the medical record. Supporting documentation includes ultrasound reports confirming complete previa and physician notes detailing active bleeding.

• Do not use this code if the documentation specifies a partial or marginal previa; other codes exist for those conditions.
• Ensure "hemorrhage" is explicitly documented; if bleeding is absent, a different code for complete placenta previa without hemorrhage should be used.
• Always sequence this code as a principal diagnosis when it is the reason for the admission or encounter.
