In simple words: This code is used when a pregnant woman with Rh-negative blood receives care because her baby has Rh-positive blood. This difference can cause the mother's body to attack the baby's blood cells.

This code describes maternal care received due to rhesus isoimmunization, a condition where the mother is Rh-negative and the fetus is Rh-positive, leading to the mother's immune system attacking the fetal red blood cells.

Example 1: A pregnant woman in her second trimester is found to be Rh-negative.Antibody screening reveals the presence of anti-D antibodies.She receives RhoGAM and undergoes regular fetal ultrasounds to monitor for signs of fetal hydrops., An Rh-negative woman who has previously given birth to an Rh-positive infant becomes pregnant again.She is given RhoGAM at 28 weeks and again after delivery if the baby is confirmed to be Rh-positive., An Rh-negative woman undergoes amniocentesis due to concerns about Rh isoimmunization.The procedure is performed to assess the severity of fetal anemia.

Documentation should include the mother's blood type and Rh factor, antibody screening results, fetal monitoring reports (e.g., ultrasound findings), administration of RhoGAM, and any other interventions or treatments provided.

** This code specifically refers to maternal care related to Rh incompatibility.It does not include the administration of RhoGAM, which is coded separately.
