October 4, 2018

Effective for dates of service on or after January 1, 2019, HCPCS Level III local codes Z0324, Z0326, Z0328 and Z0329 for sign language interpreter services will be discontinued. Codes Z0324 and Z0326 will be replaced by national HIPAA-compliant HCPCS Level II code T1013. HCPCS Level II national code T1013 will be required to bill sign language interpreter services. Providers submitting UB-04 claim forms or ANSI 837I transactions must bill revenue codes in addition to national procedure codes. The Sign Language Interpreter Services Code Conversion Crosswalk is available for reference.

Sign language interpreter services are a benefit to facilitate effective communication with deaf or hearing-impaired Medi-Cal recipients. Sign language interpreter services are not covered for recipients receiving these services in a health facility that is required by law to provide sign language interpreter services.

Updated manual pages will be released in a future Medi-Cal Update.
