Other heavy for gestational age newborn

This code identifies a newborn who is significantly larger than average for their gestational age, but whose birth weight is less than 4500 grams. This condition suggests potential underlying maternal or fetal factors contributing to accelerated fetal growth.

Apply this code when documentation indicates a newborn is classified as "large for gestational age" (LGA) based on growth charts, and their birth weight is explicitly stated as less than 4500 grams. This code is appropriate when the specific causes of LGA, such as maternal diabetes, have been ruled out or are not documented.

• Do not use this code if the newborn's birth weight is 4500 grams or more; instead, use the appropriate code for macrosomia.
• Ensure documentation clearly distinguishes between LGA and macrosomia based on specific weight criteria.
• Always review for co-occurring conditions like maternal diabetes (gestational or pre-existing) as these would necessitate different primary codes for the infant.
