Oligohydramnios, second trimester, fetus 3

This code signifies a lower than normal volume of amniotic fluid surrounding the fetus during the second trimester of pregnancy, specifically when there are three fetuses present. Oligohydramnios can indicate potential fetal compromise or underlying maternal conditions.

Use this code when documentation clearly states oligohydramnios diagnosed in the second trimester of a triplet pregnancy. Confirmation of gestational age and the presence of three fetuses are crucial for accurate application.

• Ensure the documentation specifies "second trimester" and "fetus 3" for accurate code assignment.
• Distinguish from oligohydramnios in other trimesters (O41.01- for first, O41.03- for third) or with a different number of fetuses.
• Always sequence this code after the primary obstetric complication or condition, if applicable.
