Code Description

ICD-10 O36.0929 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, second trimester (other fetus).

Key Diagnostic Point:

Maternal care for rhesus isoimmunization involves the management of a condition where the mother's immune system produces antibodies against the Rh factor present in the fetus's blood. This can lead to hemolytic disease of the newborn, which can cause severe complications such as fetal anemia, jaundice, and even heart failure. In the second trimester, careful monitoring is crucial as the fetus is still developing, and any complications can lead to growth restriction or fetal distress. Management may include regular ultrasounds to assess fetal growth and well-being, as well as potential interventions such as intrauterine transfusions if severe anemia is detected. The condition requires a multidisciplinary approach, often involving obstetricians and maternal-fetal medicine specialists to ensure optimal outcomes for both mother and fetus.

  • Navigating the need for additional testing and monitoring
  • Coordinating care among multiple specialties

Audit Risk Factors

  • Inadequate documentation of maternal-fetal monitoring
  • Failure to document the rationale for interventions
  • Misclassification of the type of isoimmunization
  • Lack of clarity in the documentation of fetal distress
