Summary
This is a revised Medicare Advantage policy for genetic testing in hereditary cardiovascular disease, effective September 1, 2026. The policy covers genetic testing for inherited cardiomyopathies, channelopathies, familial hypercholesterolemia, and Marfan syndrome, with coverage determinations based on CMS National Coverage Determinations and MAC-specific Local Coverage Determinations. Billing teams must identify the patient's MAC jurisdiction to apply the correct LCD requirements and coding guidelines.
Action Required
Before September 1, 2026: (1) Billing team must map all service locations to their applicable Medicare Administrative Contractor (MAC) jurisdiction (J5, J8, J6, JK, J15, JE, JF, JH, JL, JJ, JM, JN) using the jurisdiction table provided in the policy. (2) Update billing system rules to apply the correct MAC-specific LCD for genetic testing claims based on patient location—each MAC has different local coverage determinations (e.g., MolDX articles, molecular pathology procedures, cardiovascular disease testing). (3) Providers and clinical staff must understand covered conditions: inherited cardiomyopathies, cardiac channelopathies (Brugada syndrome, CPVT, LQTS), familial hypercholesterolemia, and Marfan syndrome. (4) Implement prior authorization workflows requiring reference to the applicable MAC's LCD before submitting genetic testing claims. (5) Train billing staff on the distinction between single-gene testing, targeted multigene panels, multicondition panels, and comprehensive panels—coverage may vary by panel type and MAC. (6) Cross-reference claims against the related policy documents listed (Genetic and Coagulation Testing for Noncancer Blood Disorders, Genetic Testing for Diagnosis of Inherited Conditions, Pharmacogenomics Testing). Failure to apply correct MAC-specific requirements will result in claim denials.
