Newborn affected by maternal cytotoxic drugs

This code signifies a newborn who has been adversely affected by cytotoxic medications administered to the mother during pregnancy. The newborn may exhibit various signs or symptoms resulting from in utero exposure to these drugs, which are typically used in chemotherapy or for autoimmune conditions.

Apply this code when documentation clearly indicates that a newborn's condition, symptom, or abnormality is directly attributed to the mother's use of cytotoxic drugs during gestation. This includes cases where the newborn presents with myelosuppression, congenital anomalies, or other drug-induced effects.

• 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 cytotoxic drugs" and links the newborn's condition to this exposure.
• Do not use this code for newborns affected by maternal non-cytotoxic drugs; refer to other codes in the P04 category for those scenarios.
