Newborn affected by slow intrauterine growth, unspecified

This code signifies a newborn diagnosed with intrauterine growth restriction (IUGR) where the specific cause or type of growth impairment is not documented. It indicates that the fetus experienced a slower-than-expected growth rate while in the uterus, leading to a smaller-than-average size at birth for gestational age.

Use this code when the medical record clearly states "slow intrauterine growth" or "intrauterine growth restriction" in a newborn, but further details regarding the specific type (e.g., symmetrical, asymmetrical) or the underlying cause are not specified. This code is appropriate when the neonate is born small for gestational age due to growth restriction, and no other more specific IUGR code can be assigned.

• Always attempt to code to a more specific type of IUGR if documented (e.g., P05.0- for symmetrical, P05.1- for asymmetrical).
• Ensure documentation explicitly links the slow growth to the intrauterine period and affects the newborn.
• Do not use this code for newborns who are simply small for gestational age without evidence of growth restriction.
