Maternal care for anti-D antibodies, first tri, fetus 5

This code signifies medical supervision and management provided to a pregnant patient during her first trimester due to the presence of anti-D (Rh) antibodies. These antibodies indicate an Rh-negative mother has been sensitized to Rh-positive fetal blood, posing a risk of hemolytic disease of the fetus and newborn (HDFN) for the fifth fetus. The care focuses on monitoring the mother's antibody titers and assessing potential fetal impact.

Apply this code when documentation confirms a pregnant patient in her first trimester is receiving care specifically for anti-D antibodies, and this is her fifth pregnancy where such monitoring is necessary. This typically involves serial antibody screens and potentially early interventions to mitigate risks to the fetus. Documentation should clearly state the presence of anti-D antibodies and the gestational age.

• Ensure the documentation specifies "first trimester" and confirms the presence of anti-D antibodies, not other types of irregular antibodies.
• Verify this is the fifth fetus for which maternal care for anti-D antibodies is being provided; the "5" in the code is specific to the fetus number.
• Do not confuse with codes for prophylactic Rh immunoglobulin administration; this code is for the care related to existing antibodies.
