Complete placenta previa with hemorrhage, first trimester

This code signifies a pregnancy complicated by a placenta that completely covers the internal cervical os, accompanied by vaginal bleeding, occurring during the first trimester. This condition poses a significant risk for maternal and fetal complications due to potential for severe hemorrhage.

Apply this code when documentation clearly indicates a complete placenta previa diagnosed in the first trimester, and the patient is actively experiencing hemorrhage. Supporting documentation should include ultrasound findings confirming complete previa and notes detailing the presence of vaginal bleeding.

• Ensure the documentation specifies "complete" placenta previa; partial or marginal previas have different codes.
• Verify the trimester of diagnosis and hemorrhage; this code is specific to the first trimester.
• Do not use this code if the hemorrhage is due to another cause, such as threatened abortion or ectopic pregnancy.
