Polyhydramnios, third trimester, fetus 5

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

Apply this code when documentation clearly indicates polyhydramnios diagnosed in a multifetal gestation of five, and the pregnancy has progressed into the third trimester. Supporting documentation would include ultrasound reports detailing amniotic fluid index (AFI) or deepest vertical pocket (DVP) measurements exceeding normal limits for the gestational age, along with the number of fetuses.

• Ensure the documentation specifies "third trimester" and "fetus 5" to accurately assign this code.
• Do not confuse with codes for polyhydramnios in earlier trimesters or with a different number of fetuses.
• Always sequence this code after the primary obstetric code indicating the pregnancy itself.
