Adaptive Biotechnologies Corporation announced that Palmetto GBA, a Medicare Administrative Contractor (MAC) that assesses diagnostic technologies through its MolDX program, has expanded coverage of the clonoSEQ Assay to include monitoring minimal residual disease (MRD) in Medicare patients with chronic lymphocytic leukemia (CLL). This adds to existing Medicare coverage in B-cell acute lymphoblastic leukemia (ALL) and multiple myeloma, which was established in January 2019. Medicare coverage for clonoSEQ is aligned with clinical practice guidelines in covered disease states which support assessing MRD at multiple time points throughout therapy to monitor treatment response and help predict patient outcomes. This expanded coverage policy is effective immediately and continues the positive momentum for clonoSEQ with over 175M lives covered to date.
