So you are charging for each panel that you run even if you run each panel using the same technique? What CPT codes are you using? CPT code 86870 is described as "Antibody identification, RBC antibodies, each panel for each serum technique." I can't decide if that means you can charge a quantity of 2 for running two panels in gel, or if it means that you can only charge 2 if you run two panels using 2 different techniques.
