Newborn light for gestational age, 2500 grams and over

This code identifies a newborn infant who is considered small for gestational age (SGA) despite having a birth weight of 2500 grams or more. It indicates that the infant's weight is below the 10th percentile for their gestational age, suggesting intrauterine growth restriction (IUGR) or other factors affecting fetal growth.

Use this code when a newborn's birth weight is 2500 grams or greater, but their weight falls below the 10th percentile for their gestational age at birth. Documentation should clearly state "light for gestational age" or "small for gestational age" and specify the birth weight and gestational age, confirming the percentile.

• Do not confuse with codes for low birth weight (P07.x) which are based solely on absolute weight thresholds.
• Ensure the medical record explicitly states the infant is "light for gestational age" or "small for gestational age" in addition to the birth weight.
• This code is typically a secondary diagnosis, with the primary diagnosis often related to the reason for the SGA status (e.g., maternal conditions, placental insufficiency).
