Drug reactions and intoxications specific to newborn

This code signifies adverse effects in a newborn resulting from maternal drug use, drug administration during labor and delivery, or direct drug exposure to the neonate. These reactions can manifest as withdrawal symptoms, toxicity, or other physiological disturbances directly attributable to the drug.

Apply this code when a newborn presents with symptoms clearly linked to drug exposure, such as neonatal abstinence syndrome (NAS), respiratory depression due to maternal opioids, or adverse effects from medications given directly to the infant. Documentation should explicitly state the drug involved and the resulting neonatal condition.

• Always sequence this code as a secondary diagnosis, following the primary diagnosis for the specific manifestation (e.g., neonatal abstinence syndrome).
• Ensure documentation clearly distinguishes between drug reactions and other neonatal conditions with similar symptoms.
• Do not use for congenital anomalies caused by maternal drug use; those are coded separately based on the specific anomaly.
