Summary
Blue Shield of California updated their genetic testing policy for hereditary hearing loss, effective November 1, 2025. The policy defines when genetic testing for GJB2, GJB6, and other hearing loss genes is considered medically necessary versus investigational, with specific criteria for diagnostic testing and preconception carrier testing.
Action Required
By November 1, 2025: Review genetic testing orders for hereditary hearing loss to ensure they meet the new medical necessity criteria. Update prior authorization processes to verify patients have suspected hearing loss or meet specific family history requirements for carrier testing. Train staff on the distinction between medically necessary testing (diagnostic testing in individuals with suspected hearing loss, carrier testing with specific family history) versus investigational testing (routine screening without hearing loss).
