Complete placenta previa with hemorrhage, second trimester

This code signifies a condition where the placenta completely covers the internal cervical os during the second trimester of pregnancy, accompanied by active vaginal bleeding. This complete placental obstruction of the birth canal poses significant risks to both mother and fetus.

Apply this code when documentation explicitly states a diagnosis of complete placenta previa with associated hemorrhage occurring between the 14th and 27th week of gestation. Clinical notes should confirm the placental position and the presence of bleeding.

• Ensure documentation specifies "complete" placenta previa; partial or marginal previa would require a different code.
• Verify the trimester of pregnancy; this code is specific to the second trimester.
• Always code the associated hemorrhage; if no hemorrhage is present, a different code for complete placenta previa without hemorrhage would be appropriate.
