Placentitis, second trimester, fetus 2

This diagnosis code indicates inflammation of the placenta occurring during the second trimester of pregnancy, specifically affecting the second fetus in a multiple gestation. Placentitis can be caused by infection and may lead to adverse pregnancy outcomes.

Assign this code when documentation confirms a diagnosis of placentitis in a pregnant patient during her second trimester, and it is explicitly linked to the second fetus. Supporting documentation would include pathology reports, ultrasound findings, or physician notes detailing placental inflammation and the affected fetus.

• Ensure the documentation specifies "second trimester" and "fetus 2" for accurate code assignment.
• Do not confuse with other placental conditions like placental abruption or placenta previa.
• Always sequence this code after the primary obstetric complication or condition if applicable.
