From a CPT coding perspective, if a high resolution polymerase chain reaction typing of the HLA A, B, and C loci are performed with typing results for each of the two alleles on the A, B, and C loci resulting in six typing results, is it appropriate to report CPT code 86812 , HLA typing; A, B, or C (eg, A10, B7, B27 ) single antigen, or 86813 , HLA typing: A, B, or C, multiple antigens? ...

Article Overview
This Find-A-Code article explains a CPT coding question involving high-resolution polymerase chain reaction typing of HLA loci. It is aimed at coders, billing staff, and transplant-related pathology or laboratory teams who need to understand how the reported testing pattern is categorized under CPT guidance. The article focuses on the distinction between single-antigen and multiple-antigen HLA typing and on how the loci-based testing scenario is handled.
Why This Topic Matters
Accurate reporting of HLA typing affects laboratory coding consistency and helps support correct claims processing for transplant-related testing. This topic is especially relevant when multiple loci and multiple determinations are involved, since the reporting approach depends on how the testing is structured.
