Code Description

ICD-10 O31.23 is a billable code used to indicate a diagnosis of continuing pregnancy after intrauterine death of one fetus or more, third trimester.

Key Diagnostic Point:

O31.23 refers to the clinical scenario where a pregnancy continues despite the intrauterine death of one or more fetuses during the third trimester. This condition is particularly relevant in multiple gestations, such as twins or higher-order multiples, where the death of one fetus can lead to significant complications for the surviving fetus(es). The management of such pregnancies requires careful monitoring and may involve specialized interventions to address complications like twin-to-twin transfusion syndrome (TTTS), where blood flow is unevenly distributed between the fetuses. The risk of complications increases as the pregnancy progresses, necessitating close surveillance for signs of distress in the surviving fetus, as well as potential delivery planning. Clinicians must navigate the emotional and psychological aspects of this situation, providing support to the parents while ensuring optimal care for the remaining fetus(es).

Complexity Factors

  • Differentiating between singleton and multiple gestation complications
  • Understanding the implications of intrauterine fetal demise on remaining fetuses
  • Navigating the emotional and psychological aspects of care
  • Managing potential complications such as TTTS

Audit Risk Factors

  • Inadequate documentation of fetal demise and its impact on the remaining fetus
  • Failure to document the management plan for the surviving fetus
  • Lack of clarity in distinguishing between complications of multiple gestation
  • Insufficient emotional support documentation for the parents
