Code Description

ICD-10 O36.0113 is a billable code used to indicate a diagnosis of maternal care for anti-d [rh] antibodies, first trimester (fetus 3).

Key Diagnostic Point:

O36.0113 refers to maternal care for a pregnant woman who has developed anti-D (Rh) antibodies during the first trimester of her pregnancy with her third fetus. This condition arises when an Rh-negative mother is exposed to Rh-positive blood, typically from a previous pregnancy or transfusion, leading to the production of antibodies that can cross the placenta and affect the fetus. The presence of these antibodies can lead to complications such as hemolytic disease of the newborn, fetal growth restriction, and fetal distress. Close monitoring and management are essential to mitigate risks, including regular ultrasound assessments to evaluate fetal growth and well-being, as well as potential interventions like intrauterine transfusions or early delivery if fetal distress is detected. Maternal care in this context involves a multidisciplinary approach, including obstetricians and maternal-fetal medicine specialists, to ensure both maternal and fetal health are prioritized throughout the pregnancy.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires understanding of immunology related to Rh incompatibility.
  • Involves monitoring for multiple potential fetal complications.
  • Documentation must reflect the complexity of maternal-fetal interactions.
  • Coding may require knowledge of additional related conditions and interventions.

Audit Risk Factors

  • Inadequate documentation of maternal antibody status.
  • Failure to document fetal monitoring results.
  • Incorrect coding of fetal complications.
  • Lack of clarity on the number of fetuses involved.
