A Cost-Recovery-Based Service

  • Red Cross regional blood service are financed by recovering expenses from the users of their services. The Red Cross charges hospitals a processing fee to cover the expenses of recruiting, collecting, testing, processing, and distributing blood and blood products. This fee is directly related to costs. Hospitals pass the charges on to the patient whose health insurance plan usually covers the expense. The blood itself is never charged for because it is a volunteer’s free gift.
