Code Description

ICD-10 O36.0922 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, second trimester (fetus 2).

Key Diagnostic Point:

Maternal care for rhesus isoimmunization refers to the management of a condition where the mother's immune system produces antibodies against the Rh factor present in the fetus's blood. This condition can lead to hemolytic disease of the newborn, which may cause fetal anemia, jaundice, and other complications. In the second trimester, careful monitoring is crucial as the fetus is still developing, and any growth restriction or distress can have significant implications for both maternal and fetal health. Management may include regular ultrasounds to assess fetal growth, non-stress tests to monitor fetal heart rate, and possibly interventions such as intrauterine transfusions if severe anemia is detected. The complexity of care increases with the need for multidisciplinary collaboration, including obstetricians and maternal-fetal medicine specialists, to ensure optimal outcomes for the mother and fetus.

  • Collaboration with maternal-fetal medicine specialists

Audit Risk Factors

  • Inadequate documentation of maternal and fetal assessments
  • Failure to capture all relevant interventions
  • Misclassification of the severity of isoimmunization
  • Lack of clear linkage between diagnosis and treatment
