Polyhydramnios, first trimester, fetus 3

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus during the first trimester of pregnancy, specifically when there are three fetuses. This condition can indicate potential fetal anomalies, maternal health issues, or complications related to multiple gestations.

Apply this code when documentation clearly indicates polyhydramnios diagnosed in the first trimester of a triplet pregnancy. Supporting documentation would include ultrasound reports detailing amniotic fluid index (AFI) or deepest vertical pocket (DVP) measurements exceeding normal limits for gestational age, along with confirmation of a triplet gestation.

• Ensure the trimester (first) and the number of fetuses (three) are explicitly documented to support this specific code.
• Do not confuse with codes for polyhydramnios in other trimesters or with different numbers of fetuses.
• Always sequence this code after the primary obstetric code indicating the pregnancy itself.
