CPT® Code 86891

The CPT® Code 86891 refers to a laboratory procedure that involves the collection, processing, and storage of autologous blood or its components, specifically during intra-operative or post-operative settings. Autologous blood is defined as blood that is collected from the patient themselves, which can include whole blood or specific components such as red blood cells, leukocytes, and platelets. This procedure is particularly beneficial as it allows for the preparation of blood products that are specifically labeled for the individual patient, thereby eliminating the need for the extensive screening and testing that is typically required for blood intended for general supply use. Patients have the option to donate their blood as early as 42 days prior to a scheduled surgical procedure, and they may continue to donate on a weekly basis, provided they remain hemodynamically stable. The primary advantage of utilizing autologous blood products is the significant reduction in the risk of transfusion reactions and the potential transmission of infectious diseases, which are concerns associated with allogeneic blood transfusions. The process of collection involves gathering blood or blood components from a wound, body cavity, or drainage tube into a reservoir until a sufficient volume is achieved. Once collected, the salvaged blood undergoes processing, which includes centrifugation to concentrate the components and washing with an isotonic solution, typically saline. Finally, the processed blood is transferred into a transfusion bag, making it ready for immediate use or for later transfusion back into the patient.
