Code Description

ICD-10 O36.012 is a billable code used to indicate a diagnosis of maternal care for anti-d [rh] antibodies, second trimester.

Key Diagnostic Point:

Maternal care for anti-D [Rh] antibodies during the second trimester is crucial for managing potential fetal complications arising from Rh incompatibility. When a Rh-negative mother carries a Rh-positive fetus, the mother's immune system may produce antibodies against the Rh factor, leading to hemolytic disease of the fetus and newborn (HDFN). This condition can result in fetal anemia, hydrops fetalis, and intrauterine growth restriction (IUGR). Regular monitoring through ultrasound and Doppler studies is essential to assess fetal well-being, including growth parameters and blood flow dynamics. Maternal care may involve administering Rh immunoglobulin (RhoGAM) to prevent antibody formation and close surveillance for signs of fetal distress or complications. The second trimester is a critical period for intervention, as early detection and management can significantly improve outcomes for both mother and fetus.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Understanding of Rh incompatibility and its implications for fetal health.
  • Need for accurate documentation of maternal antibody screening and results.
  • Monitoring protocols for fetal growth and distress indicators.
  • Coordination of care among obstetricians, maternal-fetal medicine specialists, and pediatricians.

Audit Risk Factors

  • Inadequate documentation of maternal antibody status and follow-up care.
  • Failure to document fetal monitoring results and interventions.
  • Misclassification of the trimester or gestational age.
  • Omission of relevant co-morbidities or complications.
