Sign Language Interpreter Services Code Conversion Reminder

October 19, 2018

The sign language interpreter services code conversion will replace HCPCS Level III local codes, commonly referred to as local codes, with HIPAA-compliant HCPCS Level II national codes. This billing requirement for sign language interpreter services is mandated by HIPAA and is effective for claims with dates of service on or after January 1, 2019.

For claims with dates of service on or after January 1, 2019, the sign language interpreter services code conversion will be replacing HCPCS Level III local codes Z0324 and Z0326 with HCPCS Level II national code T1013 (sign language or oral interpretive services, per 15 minutes).

As of January 1, 2019, HCPCS Level III local codes Z0328 and Z0329 used to bill for sign language interpreter services will no longer be reimbursable.

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

Providers are encouraged to watch for sign language interpreter service updates in the NewsFlash area of the Medi-Cal website and in the monthly Medi-Cal Update. Providers may complete the Medi-Cal Subscription Service (MCSS) Form to receive timely notifications related to sign language interpreter services.
