Newborn light for gestational age, 500-749 grams

This code signifies a newborn infant who is small for their gestational age, specifically weighing between 500 and 749 grams at birth. This condition indicates intrauterine growth restriction (IUGR) resulting in a significantly low birth weight for the baby's gestational period.

Apply this code when documentation clearly states a newborn's birth weight is within the 500-749 gram range and they are identified as light for gestational age. This typically applies to premature infants who have experienced restricted growth in utero.

• Ensure the birth weight is precisely documented as 500-749 grams; other weight ranges have different codes.
• Confirm the "light for gestational age" status is explicitly stated or clearly implied by the clinical context.
• Sequence this code as a secondary diagnosis following the primary code for prematurity (e.g., P07.0x, P07.1x, P07.3x) if applicable.
