2025 ICD-10-CM code P05.9
This code describes a newborn affected by slow intrauterine growth, unspecified.
Medical necessity for the use of P05.9 is established by the clinical findings indicating slow intrauterine growth. This typically includes a birth weight below the 10th percentile for gestational age.Further diagnostic testing and monitoring may be medically necessary to assess for related complications and determine the underlying cause of growth restriction.
Diagnosis and care related to the newborn's growth restriction would typically fall under the purview of neonatologists and pediatricians. They are responsible for assessing the newborn's condition, ordering necessary tests, and determining appropriate treatment or management strategies.

In simple words: This code indicates that a baby was born smaller than expected for its gestational age, but the specific reason is unknown.
This ICD-10-CM code represents a newborn affected by slow intrauterine growth that is not otherwise specified.It indicates that the fetus did not reach its expected growth potential during gestation, but the specific reason or category of growth restriction (e.g., light for gestational age, small for gestational age) is not documented.
Example 1: A newborn is delivered at 38 weeks gestation weighing 2,200 grams.No specific cause for the low birth weight is identified, thus P05.9 is applied., A baby is born with a low birth weight. Initial tests do not reveal a specific reason such as placental insufficiency or chromosomal abnormalities. P05.9 is used until further investigations provide a more definitive diagnosis., A term infant is small for gestational age, and the mother has a history of smoking during pregnancy. While smoking is a likely contributing factor, if definitive testing for fetal growth restriction related specifically to smoking wasn't done, P05.9 may be used.
Documentation should support the slow intrauterine growth. This may include ultrasound measurements during pregnancy, birth weight, and Apgar scores. Any known maternal factors (e.g., smoking, drug use, medical conditions) should also be documented.If specific investigations were done to identify the cause of growth restriction, those results should be included.
