Maternal care for anti-D antibodies, second tri, fetus 2

This code signifies that a pregnant patient in her second trimester is receiving specialized medical management due to the presence of anti-D (Rh) antibodies. This condition indicates Rh incompatibility, where the mother's immune system has produced antibodies against the Rh-positive red blood cells of the fetus, specifically affecting the second fetus in a multiple gestation pregnancy.

Use this code when documentation confirms maternal anti-D antibodies are present during the second trimester of a twin pregnancy, and the mother is receiving care related to this condition for the second fetus. This typically involves monitoring for fetal hemolytic disease and planning for potential interventions. Documentation should clearly state the trimester, the presence of anti-D antibodies, and that the care is directed towards the second fetus.

• Ensure the documentation specifies "second trimester" and "fetus 2" in a multiple gestation.
• Do not confuse with codes for other types of maternal antibodies or for single gestations.
• Always sequence this code as a primary diagnosis when the anti-D antibody care is the reason for the encounter.
