Newborn light for gestational age, 1000-1249 grams

This code signifies a liveborn infant who is small for gestational age, specifically weighing between 1000 and 1249 grams at birth. This condition indicates restricted fetal growth, where the newborn's weight is below the 10th percentile for their gestational age.

Use this code when documentation confirms a liveborn infant's birth weight is within the 1000-1249 gram range and the neonatologist or pediatrician has diagnosed the infant as light for gestational age. This diagnosis is typically based on a comparison of birth weight to a standard growth chart for the infant's documented gestational age.

• Ensure the birth weight is precisely documented as 1000-1249 grams; other weight ranges have different codes.
• Confirm the diagnosis of "light for gestational age" is explicitly stated, not just low birth weight.
• Sequence this code as a secondary diagnosis following the appropriate Z38 code for liveborn infant.
