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.
