Z37.2

Twins, both liveborn

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

Code Description

ICD-10 Z37.2 is a billable code used to indicate a diagnosis of twins, both liveborn.

Key Diagnostic Point:

Z37.2 is used to indicate that both twins born during a delivery are liveborn. This code is essential for capturing the birth outcome in multiple gestations, which can influence maternal and neonatal health status. The presence of twins can lead to increased healthcare utilization due to higher risks associated with multiple pregnancies, such as preterm birth, low birth weight, and complications during delivery. Social determinants of health, such as socioeconomic status, access to prenatal care, and maternal education, play a significant role in the health outcomes of both the mother and the twins. Preventive care measures, including regular prenatal visits, nutritional counseling, and screening for gestational diabetes, are crucial in managing the health of mothers expecting twins. Aftercare for both the mother and the twins involves monitoring for potential complications and ensuring appropriate follow-up care, which can include pediatric visits and maternal mental health support.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires accurate documentation of multiple births.
  • Potential for complications that may require additional coding.
  • Need for clear differentiation between liveborn and stillborn outcomes.
  • Influence of social determinants on maternal and neonatal health.

Audit Risk Factors

  • Inadequate documentation of the birth outcome.
  • Failure to capture complications related to multiple gestations.
  • Incorrect sequencing of codes related to maternal and neonatal care.
  • Lack of clarity in differentiating between liveborn and stillborn.
