Summary & Overview
HCPCS P9040: Red Blood Cells, Leukocytes Reduced, Irradiated, Each Unit
HCPCS Level II code P9040 denotes a single unit of red blood cells that is both leukocyte-reduced and irradiated. This specialized blood product is used to minimize immune reactions and prevent transfusion-associated graft-versus-host disease in at-risk patients, making it a clinically important item across hospitals and infusion centers nationwide. The code is relevant to hospital-based transfusion services and outpatient infusion sites where specialized blood products are administered.
Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of clinical context for P9040, payer coverage patterns, typical service settings, and common billing considerations. The publication outlines reimbursement benchmarks where available, common modifier usage patterns, and policy or coverage nuances affecting access to leukoreduced, irradiated red blood cells.
This summary equips clinical billing staff, transfusion services managers, and policy analysts with the essential information needed to understand what P9040 represents, which payers commonly cover it, and which operational and policy factors influence its use and billing.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with acute myeloid leukemia is admitted to the hematology-oncology inpatient unit for febrile neutropenia and symptomatic anemia. The treating team orders transfusion of red blood cells that have been processed as leukocyte-reduced and irradiated due to the patients immunocompromised state and prior hematopoietic stem cell transplant. Blood bank staff select and prepare each unit as P9040 (red blood cells, leukocytes reduced, irradiated, each unit), perform required compatibility testing, and document product lot numbers and irradiation details in the transfusion record. A bedside nurse verifies patient identity, obtains informed consent, monitors vital signs before, during, and after transfusion, and documents any transfusion reactions. The typical workflow includes: blood bank receipt of the order, crossmatch and product selection, irradiation performed per institutional protocol (typically within 14 days of transfusion), delivery to the floor, bedside verification and administration, and post-transfusion documentation and monitoring in the electronic medical record.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Default/No modifier | Use when no specific modifier is applicable to the service |
22 | Increased procedural services | Use if unusually complex blood product processing imposes significantly greater resource use documented in the record
