The Celiac Disease Reflexive Cascade begins with Immunoglobulin A. Depending on findings, one or more reflexive tests may be required in order to provide a clinical interpretation. Tests added may include Tissue Transglutaminase Antibody, IgA; Tissue Transglutaminase Antibody, IgG; Endomysial Antibody, IgA by IFA; Deamidated Gliadin Peptide (DGP) Antibody, IgA; Deamidated Glaidin Peptide (DGP) Antibody, IgG; and/or Celiac Disease Dual Antigen Screen. Refer to the Celiac Testing Algorithm found at https://www.arupconsult.com/Algorithms/CeliacDz.pdf. Additional charges apply.
82784; if reflexed additional CPT codes may apply: 83516, 83516 x2 and/or 86256.
add 83516; if reflexed to tTG IgA and Gliadin IgA, add 83516 x 2; if reflexed to tTG IgG and Gliadin IgG, add 83516 x2.; if IgA is greater than or equal to the normal age range, add 83516; if reflexed, add 86256 and 83516.
