2025 ICD-10-CM code P05
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Perinatal conditions - Disorders of newborn related to slow fetal growth and fetal malnutrition Certain conditions originating in the perinatal period (P00-P96) Feed
Disorders of newborn related to slow fetal growth and fetal malnutrition.
Medical necessity for further investigations (e.g., genetic testing, metabolic screening) depends on the severity of growth restriction and the presence of other symptoms or conditions.In cases of severe growth restriction, comprehensive assessment and treatment may be medically necessary.
The clinical responsibility for diagnosing and managing conditions coded under P05 rests primarily with neonatologists and pediatricians.Obstetricians may also be involved in prenatal care and assessment.

- P05-P08: Disorders of newborn related to length of gestation and fetal growth
In simple words: This code describes health problems in a newborn baby caused by poor growth or lack of nutrition while still in the mother's womb.The baby may be smaller or lighter than expected for how long the pregnancy lasted.
This ICD-10-CM code encompasses conditions in newborns resulting from slow fetal growth or fetal malnutrition.It includes situations where the infant's weight and/or length are significantly below the expected values for their gestational age. This code is specifically for use in newborn records, and not for maternal records.Further specification may be necessary using subcodes (e.g., P05.1 for newborn small for gestational age).
Example 1: A newborn baby girl is born at 37 weeks gestation weighing 1.8 kg (4 lbs) and measuring 45 cm (17.7 inches) in length.Both her weight and length are significantly below the 10th percentile for her gestational age.The neonatologist diagnoses her with P05.1 (Newborn small for gestational age)., A premature infant, born at 32 weeks, weighs 1.5 kg (3.3 lbs) and is considered "small for gestational age."After a complete examination, the neonatologist assigns the code P05.1 to the infant’s record. Additional investigations may be done to further identify the underlying cause, if any., A full-term newborn (40 weeks) presents with intrauterine growth restriction, weighing less than 2.5 kg (5.5 lbs) and exhibiting symptoms of fetal malnutrition. The doctor documents that the low birth weight is not primarily due to prematurity. Consequently, the diagnosis of P05.1 Newborn small for gestational age is coded.
Detailed documentation should include gestational age at birth, birth weight, length, head circumference, and any relevant prenatal history (e.g., maternal health conditions, prenatal ultrasound findings, nutritional intake).The underlying cause of the fetal growth restriction should be documented if identified.Clinical findings suggestive of malnutrition such as thin skin and muscle wasting should be documented.
** This code is part of a broader category that also includes disorders related to premature birth and post-maturity.Accurate coding requires careful consideration of the newborn's gestational age, weight, and length in relation to established norms.
