Partial placenta previa with hemorrhage, third trimester

This code signifies a condition where the placenta partially covers the internal cervical os during the third trimester of pregnancy, accompanied by vaginal bleeding. This placental position can obstruct the birth canal and lead to significant maternal and fetal complications due to hemorrhage.

Apply this code when documentation clearly indicates a partial placenta previa diagnosed in the third trimester, and the patient is experiencing active bleeding. Supporting documentation would include ultrasound reports confirming placental position and clinical notes detailing the presence of hemorrhage.

• Ensure the documentation specifies "partial" previa; do not use for complete or marginal previa.
• Confirm the hemorrhage is directly attributed to the placenta previa; rule out other causes of third-trimester bleeding.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter, followed by codes for any associated conditions.
