Code Description

ICD-10 P04.18 is a billable code used to indicate a diagnosis of newborn affected by other maternal medication.

Key Diagnostic Point:

P04.18 refers to newborns who are affected by maternal medications, specifically those substances that may be transmitted through the placenta or breast milk. This includes exposure to noxious substances such as illicit drugs, alcohol, and tobacco during pregnancy or lactation. Maternal drug use can lead to a range of neonatal complications, including withdrawal symptoms, growth restrictions, and developmental delays. Alcohol exposure can result in fetal alcohol spectrum disorders, while tobacco use is associated with low birth weight and respiratory issues. The clinical presentation of affected newborns may vary widely, necessitating careful assessment and management in the neonatal intensive care unit (NICU) or nursery. Accurate coding requires thorough documentation of maternal history, substance use patterns, and any observed neonatal symptoms to ensure appropriate care and follow-up.

Complexity Factors

  • Variety of substances that can affect newborns
  • Need for detailed maternal history
  • Potential for overlapping symptoms with other conditions
  • Variability in clinical presentation

Audit Risk Factors

  • Inadequate documentation of maternal substance use
  • Failure to specify the type of substance affecting the newborn
  • Misclassification of withdrawal symptoms
  • Lack of follow-up documentation on neonatal outcomes
