Code Description

ICD-10 O36.01 is a billable code used to indicate a diagnosis of maternal care for anti-d [rh] antibodies.

Key Diagnostic Point:

Maternal care for anti-D [Rh] antibodies is a critical aspect of obstetric management, particularly in pregnancies where the mother is Rh-negative and has developed antibodies against Rh-positive blood. This condition can lead to hemolytic disease of the fetus and newborn (HDFN), which may result in fetal anemia, hydrops fetalis, or even fetal demise if not properly managed. Care for these patients involves regular monitoring of fetal well-being through ultrasound assessments, Doppler studies to evaluate blood flow, and potentially intrauterine transfusions if severe anemia is detected. Additionally, maternal care may include administration of Rh immunoglobulin (RhoGAM) to prevent the formation of further antibodies in future pregnancies. The management of anti-D antibodies requires a multidisciplinary approach, often involving obstetricians, maternal-fetal medicine specialists, and pediatricians to ensure optimal outcomes for both mother and fetus.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Need for accurate identification of Rh status and antibody screening results.
  • Management of potential fetal complications such as growth restriction and distress.
  • Coordination of care among multiple specialties.
  • Documentation of ongoing monitoring and interventions.

Audit Risk Factors

  • Inadequate documentation of maternal antibody screening results.
  • Failure to document fetal monitoring and interventions.
  • Misclassification of fetal conditions related to Rh incompatibility.
  • Lack of clear communication between specialties involved in care.
