Newborn affected by other maternal noxious substances

This code signifies a newborn whose health is adversely impacted by maternal exposure to various harmful substances during pregnancy, excluding those specifically categorized elsewhere (e.g., drugs of addiction, alcohol, tobacco). These substances can include environmental toxins, certain medications not classified as drugs of addiction, or other chemical exposures. The newborn's condition is a direct result of the mother's exposure.

Apply this code when documentation clearly indicates a newborn's clinical signs or symptoms are attributable to maternal exposure to a noxious substance not otherwise specified. This includes cases where the mother was exposed to industrial chemicals, pesticides, or certain prescribed medications that are not typically considered drugs of abuse. Supporting documentation should detail the specific maternal exposure and the newborn's related clinical findings.

• Always sequence this code as a secondary diagnosis, following the newborn's specific condition or symptom.
• Ensure the documentation specifies the type of noxious substance if possible, to rule out more specific codes.
• Do not use this code for maternal drug addiction, alcohol, or tobacco use, as those have dedicated codes.
