Code Description

ICD-10 O36.0910 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, first 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 due to previous sensitization. This condition can lead to hemolytic disease of the fetus and newborn (HDFN), which can cause fetal anemia, jaundice, and even fetal distress or growth restriction. In the first trimester, the focus is on monitoring the mother and fetus for any signs of complications. Care may include blood tests to assess Rh factor status, antibody screening, and ultrasound examinations to evaluate fetal growth and well-being. The management plan may also involve counseling regarding the risks of isoimmunization and potential interventions such as Rh immunoglobulin administration to prevent further sensitization. Early detection and appropriate maternal care are crucial to mitigate risks associated with this condition.
