Code Description

ICD-10 O36.0920 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, second trimester (not applicable or unspecified).

Key Diagnostic Point:

Maternal care for rhesus isoimmunization refers to the management of pregnant women who have developed antibodies against Rh-positive blood cells, which can affect the fetus. In the second trimester, this condition may lead to complications such as fetal growth restriction, fetal distress, and hemolytic disease of the newborn. Care involves close monitoring of the fetus through ultrasound assessments, Doppler studies to evaluate blood flow, and possibly intrauterine transfusions if severe anemia is detected. The management plan may include administering Rh immunoglobulin (RhoGAM) to prevent further sensitization and to protect future pregnancies. The complexity of care increases with the need for multidisciplinary collaboration, especially in cases where fetal complications arise, necessitating careful documentation of maternal and fetal health status throughout the pregnancy.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Need for detailed fetal monitoring and assessment
  • Potential for multiple fetal complications requiring intervention
  • Variability in clinical presentation and management strategies
  • Collaboration with maternal-fetal medicine specialists

Audit Risk Factors

  • Inadequate documentation of fetal monitoring results
  • Failure to document the rationale for interventions
  • Misclassification of the severity of isoimmunization
  • Lack of clear linkage between maternal and fetal conditions
