Disorders of newborn related to short gestation and low birth weight, not elsewhere classified (P07)

The ICD-10 code P07 covers newborn disorders associated with early birth and low birth weight that don't fit into other more specific categories. These codes identify babies who are born prematurely or with a birth weight significantly below average.

This section includes codes for varying degrees of low birth weight, such as P07.0 for extremely low birth weight newborns, including weights less than 500 grams (about 1.1 pounds), and other low birth weight newborns coded from P07.1 with weight ranges up to 2499 grams. It also classifies newborns by gestational age, covering extreme immaturity from less than 23 weeks (P07.21) to late preterm infants up to 36 completed weeks (P07.39). Common terms like "very low birth weight infant," "extremely low birth weight infant," "premature baby," and "baby premature at delivery" correspond to these official ICD-10 codes, helping clarify diagnoses and coding. These codes support accurate documentation of births affected by short gestation or growth issues, enabling clear identification of the newborn’s condition for clinical and administrative purposes.
