Newborn affected by maternal use of anticonvulsants

This code signifies a newborn who has been adversely affected by the mother's therapeutic use of anticonvulsant medications during pregnancy. This includes any fetal or neonatal effects, such as withdrawal symptoms, congenital anomalies, or other physiological disturbances directly attributable to the maternal drug exposure.

Apply this code when documentation clearly indicates a newborn's condition is a direct consequence of maternal anticonvulsant therapy. This typically involves a history of maternal anticonvulsant use during gestation and clinical findings in the neonate consistent with drug exposure or withdrawal.

• Always sequence this code as a secondary diagnosis, following the code for the specific condition or symptom exhibited by the newborn.
• Ensure documentation specifies "maternal use" and "anticonvulsants" to support this code, differentiating it from other drug exposures.
• Do not use this code for maternal recreational drug use; refer to codes within the P04.4-P04.6 range for those scenarios.
