Complete placenta previa NOS or without hemor, unsp tri

This code signifies a condition where the placenta completely covers the internal cervical os, but there is no associated bleeding. The specific gestational age at which this is diagnosed is not documented or is unknown. It represents a high-risk pregnancy due to the potential for severe hemorrhage.

Apply this code when documentation clearly states "complete placenta previa" without mention of hemorrhage and the trimester is unspecified or not recorded. This is appropriate for initial diagnosis or follow-up where bleeding has not occurred. Supporting documentation would include ultrasound reports confirming complete previa and physician notes indicating absence of bleeding.

• Do not use this code if hemorrhage is documented; instead, select a code from O44.0 with a fifth character indicating hemorrhage.
• Avoid this code if the trimester is specified; use a more specific code from O44.0.
• Always review the entire medical record for any mention of bleeding or specific trimester to ensure the most precise code is chosen.
