Newborn small for gestational age, 1000-1249 grams

This code signifies a newborn infant who is small for their gestational age (SGA), specifically weighing between 1000 and 1249 grams at birth. This indicates intrauterine growth restriction (IUGR) or other factors leading to suboptimal fetal growth, resulting in a birth weight significantly below the 10th percentile for their gestational age.

Apply this code when documentation clearly states a newborn's birth weight is within the 1000-1249 gram range and they are identified as small for gestational age. This typically occurs in cases of preterm birth or full-term infants with IUGR. Physician documentation of "SGA" or "IUGR" along with the specific birth weight is crucial.

• Always confirm the exact birth weight in grams from the medical record to ensure it falls within the specified range for this code.
• Do not confuse this with codes for low birth weight (P07.x) where SGA is not explicitly documented or implied.
• Sequence this code after the primary diagnosis for the newborn's condition, if applicable, or as the principal diagnosis if SGA is the primary reason for admission/care.
