Summary & Overview
CPT 86860: RBC Elution, Immunohematology Laboratory
CPT code 86860 designates an RBC elution procedure performed by a laboratory analyst to remove and recover antibodies bound to a patient’s red blood cells. This immunohematology test is important nationally for identifying clinically significant alloantibodies or autoantibodies that affect transfusion compatibility and patient safety. Use of this code reflects specialized laboratory work typically performed in hospital blood banks and independent clinical laboratories.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The summary provides a national perspective on clinical context, billing considerations, and common payer coverage patterns.
Readers will learn the clinical purpose of the procedure, typical sites of service, common billing modifiers associated with laboratory services, and where to find related codes and documentation practices. The content also outlines which payers are commonly involved and highlights that some operational details or payor-specific rules may vary by contract.

Billing Code Overview
CPT code 86860 describes a laboratory procedure in which a lab analyst performs an RBC elution to remove antibodies bound to the patient’s red blood cells (RBCs). The process yields an eluate that can be tested to identify and characterize antibodies implicated in hemolytic transfusion reactions, autoimmune hemolytic anemia, or other clinically significant immunohematology concerns.
Service type: Immunohematology / Blood Bank Laboratory Procedure
Typical site of service: Hospital laboratory or independent clinical laboratory (blood bank/ transfusion service)
Clinical & Coding Specifications
Clinical Context
A hospitalized adult patient with a recent positive direct antiglobulin test (DAT) and a suspected immune-mediated hemolytic anemia is referred to the transfusion service for evaluation. The laboratory receives a blood specimen and performs an RBC elution (CPT 86860) to dissociate and recover antibodies bound to the patient’s red blood cells for identification. Typical workflow: specimen accessioning → DAT reviewed → elution performed by a laboratory technologist or medical laboratory scientist → eluate tested against a panel of reagent red cells to identify autoantibody or alloantibody specificity → results reported to transfusion medicine/hematology and the clinical team to guide transfusion compatibility decisions.
Typical site of service is an inpatient hospital laboratory or an independent clinical reference laboratory supporting hospital-based transfusion services. The typical patient scenario includes symptomatic hemolysis (jaundice, falling hemoglobin, elevated LDH, increased indirect bilirubin) or serologic investigation after a transfusion reaction or during prenatal antibody screening when bound antibodies are suspected.
