Genetic Testing for Idiopathic Dilated Cardiomyopathy

Comprehensive genetic testing for individuals with signs or symptoms of dilated cardiomyopathy, which is considered idiopathic after a negative workup for secondary causes, is considered medically necessary.

Targeted genetic testing for asymptomatic individuals with a first-degree relative who has dilated cardiomyopathy and a known familial variant is considered medically necessary.

Genetic testing for dilated cardiomyopathy is considered investigational in all other situations.
