Code Description

ICD-10 P04.89 is a billable code used to indicate a diagnosis of newborn affected by other maternal noxious substances.

Key Diagnostic Point:

P04.89 is used to classify newborns who are affected by maternal exposure to noxious substances, which can include drugs, alcohol, and tobacco, transmitted through the placenta or breast milk. This condition encompasses a range of potential effects on the newborn, including withdrawal symptoms, developmental delays, and other health complications. Maternal drug use, particularly opioids, can lead to neonatal abstinence syndrome (NAS), characterized by irritability, feeding difficulties, and seizures. Alcohol exposure can result in fetal alcohol spectrum disorders (FASD), which may manifest as growth deficiencies and neurodevelopmental issues. Tobacco use during pregnancy is associated with low birth weight and respiratory problems in newborns. Accurate coding requires thorough documentation of maternal substance use, the timing of exposure, and the specific effects observed in the newborn. This code is essential for tracking the impact of maternal health behaviors on neonatal outcomes and for ensuring appropriate care and resources are allocated to affected infants.

Frequently Asked Questions

What documentation is required to support the use of code P04.89?

To support the use of P04.89, coders need detailed documentation of maternal substance use, including the type of substances, timing of exposure, and any observed effects on the newborn. Clinical assessments and follow-up evaluations should also be documented to provide a comprehensive view of the infant's condition.
