Our Rheumatology Practice often orders this test to help diagnose Ankylosing Spondylitis, uveitis and other autoimmune conditions. How can I code for that reason?

>HLA typing using newer DNA technologies provides tests that are more robust, accurate and reliable in resolving allele-level differences in HLA genes that cannot be detected by serology. DNA tests can be performed using a variety of source materials (lymphocytes, whole blood, buccal swabs, biopsy samples, frozen tissue) and are less affected by viability and sample age. Several approaches to HLA typing are used, offering a range of typing resolution levels from low (antigen-level) to high (allele-level). Examples include, tests used to identify HLA types that rely on amplification of limited stretches of genomic DNA within the HLA genes.

>Standard of care testing to diagnose certain HLA related diseases/conditions when the testing is supported by the clinical literature and is informative for the direct management of a patient bearing a certain allele(s). It is not expected that more than one test would be required in a given beneficiary’s lifetime. Possible covered indications when standard laboratory testing (tissue typing) not adequate: o [HLA-B*27 for the diagnosis of certain cases of symptomatic patients with presumed ankylosing spondylitis or related inflammatory disease. HLA-B*27 is covered for ankylosing spondylitis in cases where other methods of diagnosis would not be appropriate or have yielded inconclusive results.

>Hence, it is appropriate to bill 81374 for conditions like Ankylosing Spondylitis.
