The Sign Language Interpreter Services code conversion, initially announced in the October 2018 Medi-Cal Update and NewsFlash area of the Medi-Cal website, implemented on January 1, 2019.

As of January 1, 2019, the sign language interpreter services code conversion requires providers to bill HIPAA-compliant HCPCS Level II national codes in place of non-HIPAA compliant HCPCS Level III local codes.

Effective January 1, 2019, the sign language interpreter services code conversion replaced HCPCS Level III local codes Z0324 and Z0326 with HCPCS Level II national code T1013. Previously billed non-HIPAA-compliant Level III local codes Z0328 and Z0329 were terminated and are no longer reimbursable.
