Polyhydramnios, second trimester, fetus 3

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus during the second trimester of pregnancy, specifically when there are three fetuses present. Polyhydramnios can lead to various maternal and fetal complications, including preterm labor, placental abruption, and fetal anomalies.

Apply this code when documentation clearly indicates polyhydramnios diagnosed in a multifetal pregnancy with triplets during the second trimester. Supporting documentation should include ultrasound findings detailing the amniotic fluid index (AFI) or deepest vertical pocket (DVP) measurements exceeding normal limits for gestational age, along with the confirmed presence of three fetuses.

• Ensure the trimester (second) and the number of fetuses (three) are explicitly documented.
• Do not confuse with codes for polyhydramnios in singleton pregnancies or different trimesters.
• Code any associated maternal or fetal conditions (e.g., gestational diabetes, fetal anomalies) separately.
