Newborn affected by maternal use of unspecified medication

This code signifies that a newborn has been adversely affected by a medication taken by the mother during pregnancy, where the specific drug is not identified in the medical record. The newborn may exhibit various signs or symptoms, or the maternal medication exposure may be noted without specific neonatal effects yet manifesting.

Assign this code when documentation indicates a newborn's condition or status is linked to maternal medication use, but the specific medication is not specified. This is often used when the maternal history notes drug exposure, but the exact substance is unknown or not documented. Supporting documentation includes maternal history, newborn assessment, and physician notes.

• Always attempt to identify the specific maternal medication for a more precise code assignment (e.g., P04.10, P04.11, P04.12).
• This code should be sequenced as a secondary diagnosis, following the code for the newborn's specific condition or symptom, if any.
• Do not use this code if the maternal medication was for therapeutic purposes and had no adverse effect on the newborn.
