Code Description

ICD-10 O36.013 is a billable code used to indicate a diagnosis of maternal care for anti-d [rh] antibodies, third trimester.

Key Diagnostic Point:

O36.013 refers to maternal care for women who have developed anti-D (Rh) antibodies during pregnancy, specifically in the third trimester. This condition arises when an Rh-negative mother is exposed to Rh-positive fetal blood, leading to the production of antibodies that can cross the placenta and affect the fetus. The presence of these antibodies can result in various fetal complications, including hemolytic disease of the newborn, fetal growth restriction, and fetal distress. Monitoring and management during this critical period involve regular ultrasounds to assess fetal growth and well-being, as well as potential interventions such as intrauterine transfusions if severe anemia is detected. Maternal care also includes counseling regarding the risks associated with Rh incompatibility and the importance of follow-up care postpartum to prevent future complications in subsequent pregnancies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Understanding the implications of Rh incompatibility on fetal health.
  • Differentiating between mild and severe cases of antibody presence.
  • Knowledge of appropriate monitoring protocols and interventions.
  • Navigating documentation requirements for high-risk pregnancies.

Audit Risk Factors

  • Inadequate documentation of maternal antibody testing results.
  • Failure to document fetal monitoring and assessment findings.
  • Misclassification of the severity of Rh sensitization.
  • Lack of follow-up care documentation post-delivery.

Specialty Focus

Medical Specialties
