Polyhydramnios, third trimester, fetus 4

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus during the third trimester of pregnancy, specifically when the condition affects the fourth fetus in a multiple gestation. Polyhydramnios can lead to various maternal and fetal complications, including preterm labor, placental abruption, and fetal malformations.

Apply this code when documentation clearly indicates polyhydramnios diagnosed in the third trimester of a multiple gestation pregnancy involving four fetuses. The medical record must specify the trimester and the number of fetuses affected. This code is appropriate when the polyhydramnios is a significant clinical finding requiring monitoring or intervention.

• Ensure the medical record explicitly states "third trimester" and "fetus 4" in the context of polyhydramnios.
• Do not use this code for polyhydramnios occurring in earlier trimesters or for a different number of fetuses.
• Code any associated maternal or fetal conditions contributing to or resulting from the polyhydramnios.
