Maternal care for other rhesus isoimmunization, first trimester
ICD-10 O36.091 is a billable code used to indicate a diagnosis of maternal care for other rhesus isoimmunization, first trimester.
Maternal care for rhesus isoimmunization refers to the management of a condition where the mother’s immune system produces antibodies against the Rh factor present in the fetal blood. This condition can lead to hemolytic disease of the newborn, which may cause fetal anemia, jaundice, and other complications. In the first trimester, careful monitoring is crucial as the fetus is particularly vulnerable. Maternal care includes regular blood tests to monitor Rh factor levels, ultrasound assessments to evaluate fetal growth and well-being, and potential interventions such as Rh immunoglobulin administration to prevent sensitization. The management of fetal problems such as growth restriction or fetal distress is also critical, as these can arise from the effects of isoimmunization. Early detection and intervention can significantly improve outcomes for both the mother and the fetus.
Documentation must include maternal blood type, Rh factor status, and results of antibody screening. Detailed records of fetal assessments and any interventions performed are essential.
Management of a pregnant woman with a known Rh-negative status who has had a previous pregnancy affected by Rh isoimmunization.
Coders must ensure that all relevant maternal and fetal assessments are documented to support the diagnosis and any associated procedures.
High-risk pregnancy documentation must include comprehensive details about maternal health, fetal growth assessments, and any complications arising from isoimmunization.
Monitoring of a fetus showing signs of anemia or growth restriction due to maternal Rh isoimmunization.
High-risk scenarios require meticulous documentation of all clinical findings and interventions to justify the complexity of care provided.
Used during initial prenatal visits to determine maternal Rh status.
Document the reason for testing and results.
Ensure that the test is linked to the diagnosis of Rh isoimmunization.
Accurate coding of O36.091 is crucial for ensuring appropriate maternal care management and reimbursement. It reflects the complexity of care required for mothers with Rh isoimmunization and helps in tracking outcomes for both mothers and infants.
