Disorders of newborn related to slow fetal growth and fetal malnutrition (P05) ICD-10-CM

About the P05 Code Range

The ICD-10 code section P05 is used to document disorders in newborns caused by slow fetal growth and fetal malnutrition, including babies who are light or small for gestational age. These codes classify newborns based on their weight relative to gestational age, which is essential for identifying growth issues affecting newborn health.

This section covers detailed subcodes such as P05.0 for "Newborn light for gestational age" and P05.1 for "Newborn small for gestational age." These terms correspond to infants who weigh less than expected when born, sometimes known as "small-for-dates baby" or "birth weight abnormality," helping clinicians and coders pinpoint the specific growth condition. Additionally, codes like P05.2 address newborns affected by fetal malnutrition even if they are not classified as light or small for gestational age. The broader code P05.9 captures unspecified slow intrauterine growth conditions, sometimes linked with terms like intrauterine growth restriction (IUGR). Using these codes ensures accurate classification of newborn growth disorders reflecting fetal development concerns.
