Exceptionally large newborn baby

This code signifies a newborn infant whose birth weight is significantly above the 90th percentile for gestational age, often referred to as macrosomia. It indicates an infant born with an unusually large size, regardless of the underlying cause.

Apply this code when documentation clearly states "exceptionally large newborn," "macrosomia," or a birth weight exceeding the 90th percentile for gestational age without a specified maternal diabetic condition. This diagnosis is typically made at birth based on physical assessment and birth weight.

• Ensure the medical record explicitly states "exceptionally large" or provides a birth weight that meets macrosomia criteria.
• Carefully review documentation to rule out maternal diabetes (gestational or pre-existing) as the cause, as these conditions have specific Excludes1 codes.
• This code is for the infant's condition; do not confuse it with codes for maternal conditions that might lead to macrosomia.
