Exceptionally large baby

This code describes a newborn infant whose birth weight is significantly above the average for gestational age, typically defined as exceeding 4,000 grams (approximately 8 pounds 13 ounces) regardless of gestational age, or above the 90th percentile for gestational age. This condition is often associated with maternal diabetes or excessive maternal weight gain.

Use this code for liveborn infants diagnosed with macrosomia or large for gestational age (LGA) at birth. Documentation should clearly state the infant's birth weight and/or a diagnosis of macrosomia or LGA. This code is typically assigned as a secondary diagnosis to reflect a significant finding affecting the newborn.

• Do not confuse with codes for infants large for dates due to prolonged gestation (e.g., 765.1x).
• Ensure the birth weight is documented to support the diagnosis of an exceptionally large baby.
• This code is for the infant's condition, not the maternal condition that may have caused it.
