Maternal renal and urinary tract diseases affecting fetus or newborn

This code signifies a fetal or newborn condition directly resulting from the mother's pre-existing or gestational renal or urinary tract disease. It indicates that the maternal kidney or bladder pathology has an adverse impact on the developing fetus or the neonate.

Use this code when documentation clearly links a fetal anomaly, growth restriction, or neonatal complication (e.g., prematurity, low birth weight, respiratory distress) to a maternal diagnosis such as chronic kidney disease, pyelonephritis, or gestational hypertension with renal involvement. Supporting documentation would include maternal medical history, fetal ultrasound findings, and neonatal assessment.

• Always sequence this code as a secondary diagnosis, following the primary condition of the fetus or newborn.
• Ensure the medical record explicitly states the maternal renal/urinary condition as the cause or contributing factor to the fetal/neonatal issue.
• Do not use for maternal conditions that do not directly impact the fetus or newborn.
