Summary
BCBS Mississippi has established new coverage criteria for genetic testing in dilated cardiomyopathy cases. Comprehensive genetic testing is now covered for patients with idiopathic dilated cardiomyopathy after negative workup for secondary causes, and targeted testing is covered for asymptomatic first-degree relatives with known familial variants.
Action Required
Immediately: Billing team must ensure proper documentation requirements are met before submitting genetic testing claims for dilated cardiomyopathy. Verify patients have completed standard workup (clinical exam, blood pressure monitoring, ECG, echocardiography, coronary artery disease workup) and that secondary causes have been ruled out before billing comprehensive genetic testing. For asymptomatic relatives, confirm first-degree relationship and known familial variant documentation. Claims for genetic testing outside these criteria will be denied as investigational.
