Anemia complicating pregnancy, third trimester

This diagnosis code signifies the presence of anemia in a pregnant patient during her third trimester. It indicates that the anemia is considered a complication of the pregnancy, requiring clinical attention and management.

Apply this code when documentation explicitly states anemia complicating a pregnancy in the third trimester. This includes iron deficiency anemia, megaloblastic anemia, or other specified anemias that are directly impacting the pregnancy.

• Ensure the medical record clearly specifies "third trimester" for accurate code assignment.
• Do not use this code if the anemia is incidental to the pregnancy or pre-existing and not exacerbated by pregnancy.
• Sequence this code as a secondary diagnosis following the primary obstetric code (e.g., O80-O82 for delivery).
