CA Hub & Spoke System

The CA H&SS is a component of the California MAT Expansion, and is being implemented as a way to improve, expand, and increase access to MAT services throughout the state. The program will improve access to MAT services, especially in counties with the highest overdose rates. The implementation of the CA H&SS will increase the total number of physicians, physician assistants and nurse practitioners prescribing buprenorphine, thereby increasing the availability of MAT for patients with OUDs. All Hub and Spokes must obtain or be currently enrolled in Drug Medi-Cal or Fee-for-Service Medi-Cal, as well as remain in good standing throughout the contract period.
