A patient had a triple CABG and 3 days after the procedure, the same Dr. sees the patient and documents postoperative anemia. The patient has transfusions. Modifier 24 is unrelated E/M service by same Dr. during a postop period. Modifier 79 is unrelated procedure or service by the same Dr. during the postop period. I am leaning toward modifier 79 but I am confused. Help please.
