Oligohydramnios affecting fetus or newborn

This code represents a condition where there is an abnormally low amount of amniotic fluid surrounding the fetus, specifically when this deficiency is documented as having an adverse effect on the fetus or newborn. Oligohydramnios can lead to various complications, including fetal compression, pulmonary hypoplasia, and umbilical cord compression.

Use this code when documentation explicitly states oligohydramnios affecting the fetus or newborn. This typically occurs when a neonate presents with complications directly attributable to insufficient amniotic fluid during gestation, such as respiratory distress or musculoskeletal deformities. Documentation should clearly link the oligohydramnios to the fetal or neonatal outcome.

• Do not use this code if oligohydramnios is present but no adverse effect on the fetus or newborn is documented.
• Consider sequencing this code after the primary condition or complication in the newborn that resulted from the oligohydramnios.
• Distinguish from codes for oligohydramnios affecting the mother (e.g., 658.0x) when the focus is on the maternal condition.
