Newborn aff by maternal exposure to environ chemical substnc

This code signifies a newborn diagnosed with conditions or symptoms attributable to the mother's exposure to environmental chemical substances during pregnancy. This includes a range of potential adverse effects on the neonate resulting from maternal contact with toxins, pollutants, or other harmful chemicals in their environment.

Apply this code when documentation clearly links a newborn's health issue (e.g., congenital anomalies, developmental delays, specific toxic effects) to the mother's exposure to environmental chemicals. This typically requires a documented maternal history of exposure and a physician's assessment connecting the exposure to the neonatal outcome.

• Always sequence this code as a secondary diagnosis, following the code for the specific condition or symptom manifested by the newborn.
• Ensure the medical record explicitly states the maternal exposure to environmental chemical substances and its impact on the newborn.
• Distinguish from maternal drug use or medication exposure, which are coded differently (e.g., P04.4, P04.1).
