Medical Provider Network (MPN)

PRISM has developed its own Medical Provider Network (MPN) with the assistance of a contracted administrator (WellComp). The MPN was established in accordance with the SB 899 reforms that occurred in April 2004, and can provide employer control over the injured worker’s medical care through the life of the claim. The MPN is required for members of the PWC Program and available to all EWC Program members should they desire to use it. The network includes Kaiser Occupational Health, Sutter at Work, and various individual physicians nominated by the PRISM membership. PRISM’s network contains more than 4,400 physicians statewide. The Medical Provider Network can be accessed through the MPN website. If you have any suggestions for additions or changes to the network, please contact Paul Stanley or call (916) 850-7305.
