Z38.5

Twin liveborn infant, unspecified as to place of birth

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z38.5 is a billable code used to indicate a diagnosis of twin liveborn infant, unspecified as to place of birth.

Key Diagnostic Point:

Z38.5 is used to classify a twin liveborn infant when the place of birth is not specified. This code is crucial for understanding the health status of newborns, particularly in the context of multiple births, which can have unique health implications. Factors influencing health status include maternal health, access to prenatal care, and socioeconomic conditions. Preventive care for twins may involve increased monitoring for developmental milestones and screening for congenital conditions. Social determinants such as family support, housing stability, and access to healthcare services play a significant role in the health outcomes of twin infants. Aftercare may include regular pediatric visits to monitor growth and development, as well as addressing any potential complications associated with multiple births.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Documentation of multiple births can be complex due to varying health statuses.
  • Need for detailed maternal health history to understand potential complications.
  • Increased risk of coding errors due to the unspecified place of birth.
  • Potential for confusion with other Z codes related to liveborn infants.

Audit Risk Factors

  • Inadequate documentation of the place of birth.
  • Failure to capture relevant maternal health information.
  • Misclassification of the infant's health status.
  • Inconsistent coding practices across different healthcare providers.

Inclusion Criteria

Use Z38.5 When
  • Z codes should be used when the primary reason for the encounter is not a disease or injury but rather a health status or social circumstance
  • 5 should be sequenced appropriately, often following codes for any complications or conditions related to the infant's health

Frequently Asked Questions

When should Z38.5 be used instead of Z38.1 or Z38.2?

Z38.5 should be used when the place of birth is unspecified, while Z38.1 and Z38.2 should be used when the birth location is known.
