Clinical & Coding Specifications
Clinical Context
A 58-year-old male with a history of severe hemolytic anemia secondary to autoimmune hemolytic anemia is admitted for symptomatic anemia with hemoglobin of 6.8 g/dL, tachycardia, and dyspnea. The transfusion medicine service orders washed red blood cells to reduce the risk of febrile or allergic transfusion reactions and to remove plasma proteins. The typical workflow begins with the treating physician documenting indication and transfusion consent, the blood bank identifying and crossmatching compatible units, performing the washing process per institutional protocol, and issuing P9022 units to the inpatient nursing team. Vital signs and transfusion reaction checks are performed pre-, during-, and post-transfusion in a hospital inpatient or outpatient infusion center setting. Orders for washed red blood cells are commonly placed for patients with a history of severe allergic transfusion reactions, IgA deficiency with anti-IgA antibodies, or repeated febrile nonhemolytic transfusion reactions despite premedication. Each unit is billed using HCPCS Level II code P9022 for washed red blood cells, with documentation of unit number, washing procedure, indication, informed consent, and transfusion monitoring in the medical record.
