Placentitis, third trimester, fetus 5

This diagnosis code signifies inflammation of the placenta occurring during the third trimester of pregnancy, specifically affecting the fifth fetus in a multiple gestation. Placentitis can be caused by various infections and may lead to adverse pregnancy outcomes.

Use this code when documentation clearly indicates placentitis in a pregnant patient who is in her third trimester and is carrying quintuplets, with the diagnosis specifically pertaining to the fifth fetus. Supporting documentation should include pathology reports, infectious disease workups, or obstetrician notes detailing the placental inflammation and the specific fetus affected.

• Ensure the trimester (third) and the specific fetal number (fifth) are explicitly documented.
• Do not confuse with other placental conditions like placental abruption or placenta previa.
• Code any underlying infectious agent separately if identified and documented.
