Disorders of newborn related to length of gestation and fetal growth (P05-P08)
ICD-10-CM codes P05 through P08 cover medical conditions affecting newborns related to their birth timing and size, specifically disorders associated with the length of gestation and fetal growth. These codes identify whether a newborn is unusually small or large for their gestational age, or born prematurely or post-term, which helps guide appropriate care and monitoring.
The P05 codes describe newborns with slow fetal growth or fetal malnutrition, including terms like "light for gestational age" and "small for gestational age"; also known as small-for-dates baby or birth weight abnormalities. These specify different weight ranges to reflect severity. The P07 codes focus on newborns with short gestation or low birth weight, covering extreme prematurity ("extreme immaturity") and various weight categories, often referred to as low birth weight infants or premature babies. Finally, the P08 codes address complications in babies with prolonged gestation or high birth weights, including exceptionally large newborns and large for gestational age newborns. These classifications support precise medical coding and allow healthcare providers to track conditions related to abnormal fetal growth or birth timing.
