Newborn small for gestational age, 750-999 grams

This code identifies a newborn infant who is small for their gestational age (SGA) and has a birth weight between 750 and 999 grams. SGA indicates that the infant's birth weight is below the 10th percentile for their gestational age, suggesting intrauterine growth restriction or other factors impacting fetal growth.

Assign this code when a neonate is documented as SGA with a birth weight specifically in the 750-999 gram range. Documentation must clearly state both the SGA status and the precise birth weight to support the use of this specific subcategory.

• Ensure the birth weight falls precisely within the 750-999 gram range; other weight ranges have different codes.
• Confirm documentation explicitly states "small for gestational age" or provides percentile data indicating SGA.
• Sequence this code as a secondary diagnosis following the appropriate code for the newborn's birth status (e.g., Z38.00 for single liveborn infant).
