Infct of amniotic sac and membrns, unsp, second tri, fetus 3

This code signifies an infection of the amniotic fluid and surrounding membranes (chorioamnionitis) occurring during the second trimester of pregnancy, specifically affecting the third fetus in a multiple gestation. The specific type of infection is not identified.

Use this code when documentation indicates chorioamnionitis in a second-trimester pregnancy with triplet or higher order gestation, and the infection is unspecified. Clinical scenarios include premature rupture of membranes (PROM) with signs of infection, maternal fever, uterine tenderness, or fetal tachycardia, where the infection type is not specified.

• Always specify the trimester and fetal number when documented.
• Do not use this code if the specific infectious organism is identified; instead, code the specific infection.
• Sequence this code after any obstetric complication codes, if applicable.
