Polyhydramnios, second trimester, fetus 5

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus during the second trimester of pregnancy, specifically when there are five fetuses present. Polyhydramnios can be associated with various maternal or fetal complications, including congenital anomalies, gestational diabetes, or multiple gestations.

Apply this code when documentation clearly indicates polyhydramnios diagnosed in the second trimester of a quintuplet pregnancy. This diagnosis is typically made via ultrasound demonstrating an amniotic fluid index (AFI) above the 95th percentile for gestational age or a deepest vertical pocket (DVP) exceeding 8 cm.

• Ensure the documentation explicitly states "second trimester" and "fetus 5" to support this specific code.
• Always sequence this code after the primary obstetric code for the multiple gestation (e.g., O30.2- for quintuplet pregnancy).
• Look for associated conditions, such as fetal anomalies or maternal diabetes, and code them accordingly.
