Unfortunately, there are only 3 HCPCS codes that deal with washed RBCs. P9022--Red blood cells, washed, each unit, P9054--Whole blood or red blood cells, leukocytes reduced, frozen, deglycerolized, washed, each unit, and P9057--Red blood cells, frozen/deglycerolized/washed, leukocytes reduced, irradiated, each unit. So, for a unit that hasn't been frozen and deglyced, you have to use P9022 and add the Irradiation charge code separately, if you have one built.
