CPT code 86808 denotes a laboratory screening for percent reactive antibody to donor human leukocyte antigens (HLA), used to assess the likelihood of transplant incompatibility. This immunogenetics assay is a critical step in pre-transplant evaluation because high levels of reactive antibodies correlate with increased risk of graft rejection and can determine donor eligibility. Nationally, accurate and timely use of this test supports transplant safety, organ allocation decisions, and appropriate patient counseling.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
