Placentitis, second trimester, fetus 3

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

Apply this code when documentation clearly indicates placentitis diagnosed in the second trimester of a multifetal pregnancy where the third fetus is identified as affected. This diagnosis is typically supported by ultrasound findings, maternal symptoms, or pathological examination of the placenta.

• Ensure the trimester (second) and the specific fetus affected (third) are explicitly documented.
• Do not use this code if the placentitis is due to a specific infection; instead, code the infection first, followed by this code.
• Verify that the documentation confirms a multiple gestation pregnancy.
