What 86911 covers
This laboratory service evaluates red-cell antigens at the blood-group-system level, rather than reporting routine ABO or Rh(D) typing or a single-antigen result. Transfusion-service and immunohematology laboratories perform testing on a blood specimen when broader antigen characterization is needed during transfusion evaluation. The result can help characterize a patient’s red-cell profile when selecting compatible blood. Code selection depends on the scope of antigen testing performed, distinguishing system-level typing from ABO, Rh(D), or individual-antigen testing.
Medicare lists this code with status N, meaning Medicare does not cover the service. It is a CPT blood-typing code. Report it for antigen-system typing; ABO, Rh(D), individual red-cell antigen typing, and compatibility testing are separate services represented by other codes.
