Disorders of newborn related to slow fetal growth and fetal malnutrition (P05)

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.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Insulin Resistance

Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS.

Metabolic Syndrome

A cluster of symptoms that are risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome include ABDOMINAL OBESITY; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state.
