CPT® Code 86920

The CPT® Code 86920 refers to a laboratory procedure known as a compatibility test, specifically utilizing the immediate spin technique (ISCM). This test is essential for determining the compatibility between a donor's blood and a recipient's blood prior to a transfusion. Compatibility testing, often referred to as cross matching (CM), is a critical step in ensuring that the blood transfusion process is safe and effective. The immediate spin technique involves mixing the recipient's plasma or serum with the donor's red blood cells and then subjecting this mixture to immediate centrifugation. The primary goal of this procedure is to observe any signs of hemolysis (the breakdown of red blood cells) or agglutination (clumping of cells), which would indicate incompatibility. While the ISCM method is a rapid and straightforward approach, it is important to note that it may not detect all types of ABO incompatibilities. However, a negative result from this test suggests that the donor's blood is compatible with the recipient's, allowing for the safe transfusion of the blood unit. In cases where there is a positive antibody screening or a history of clinically significant antibodies, additional testing methods such as the antiglobulin technique or incubation technique may be employed to ensure thorough compatibility assessment.
