Maternal nutritional disorders affecting fetus or newborn

This code signifies conditions where a mother's nutritional deficiencies or excesses during pregnancy negatively impact the development or health of her fetus or newborn. It encompasses a range of maternal dietary issues that lead to adverse perinatal outcomes.

Apply this code when documentation clearly links a maternal nutritional disorder (e.g., severe malnutrition, specific vitamin deficiencies, or uncontrolled gestational diabetes leading to fetal macrosomia) to an observed or anticipated effect on the fetus or newborn. This is often used as a secondary diagnosis for the newborn or fetus.

• Always sequence this code after the primary diagnosis for the newborn's specific condition (e.g., intrauterine growth restriction, fetal macrosomia).
• Ensure documentation explicitly states the maternal nutritional issue and its impact on the fetus/newborn, not just a general maternal condition.
• Distinguish from codes for maternal conditions that do not necessarily imply fetal impact, or codes for fetal conditions not directly linked to maternal nutrition.
