Other and unspecified morphological and functional abnormalities of placenta affecting fetus or newborn

This code signifies various structural or functional deviations of the placenta that negatively impact the fetus or newborn. This includes conditions like placental infarction, placental cysts, or other unspecified placental anomalies that compromise fetal well-being or neonatal health. It covers abnormalities not specifically classified elsewhere.

Use this code when documentation indicates a placental abnormality, such as placental calcification, placental hematoma, or an abnormally shaped placenta, that has a documented effect on the fetus or newborn. It is appropriate when more specific codes for placental conditions (e.g., placenta previa, abruptio placentae) do not apply. Documentation should clearly link the placental issue to fetal or neonatal complications.

• Ensure the medical record explicitly states a morphological or functional placental abnormality and its impact on the fetus or newborn.
• Avoid using this code if a more specific ICD-9-CM code exists for the documented placental condition.
• Sequence this code as a secondary diagnosis when the primary reason for admission or encounter is a related fetal or newborn condition.
