Code Description

ICD-10 O36.0930 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, third 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 third trimester, careful monitoring is crucial as the risk of hemolytic disease of the newborn increases. This condition can lead to fetal problems such as anemia, jaundice, and even fetal distress due to compromised oxygen delivery. Growth restriction may also occur if the fetus is unable to receive adequate nutrients and oxygen due to placental insufficiency. Maternal care involves regular ultrasounds to assess fetal growth, non-stress tests to monitor fetal heart rate, and potentially intrauterine transfusions if severe anemia is detected. The management plan may include administering Rh immunoglobulin (RhoGAM) to prevent further sensitization and protect future pregnancies. Close collaboration among obstetricians, maternal-fetal medicine specialists, and pediatricians is essential to ensure optimal outcomes for both mother and child.
