Maternal care for Anti-A sensitization, second tri, fetus 1

This code signifies specialized prenatal care provided to a pregnant patient in her second trimester due to the presence of Anti-A antibodies, which can lead to hemolytic disease of the fetus and newborn (HDFN). This maternal sensitization specifically targets the A antigen, indicating a potential ABO incompatibility between the mother and fetus.

Apply this code when a pregnant patient, identified as having Anti-A sensitization, is receiving ongoing monitoring and management during her second trimester. Documentation should clearly state the presence of Anti-A antibodies, the gestational age falling within the second trimester (weeks 14-27), and the specific fetus being monitored (fetus 1 in a multiple gestation or the single fetus).

• Ensure the documentation specifies "Anti-A" sensitization, as other antibody types have different codes.
• Verify the gestational trimester; this code is specific to the second trimester.
• Confirm the fetus number for multiple gestations; this code is for fetus 1.
