Helping You With Your Claim From Start To Finish
Locating a Medical Provider*
Your employer may help you find a medical provider. Depending on your location, you can also find a provider through our medical provider lookup tool. Get started here based on your location.
Medical treatment for work-related injuries and illnesses is provided through our Zenith Medical Provider Network (ZMPN), a customized network of physicians, hospitals, outpatient facilities, and ancillary service providers throughout California. Providers are included only for locations listed. Treatment obtained at locations not listed is considered out-of-network and may be subject to denial.
A chiropractor cannot be the injured employee’s treating physician after the injured employee receives 24 chiropractic visits, unless Zenith has authorized additional visits in writing. The term “chiropractic visit” means any chiropractic office visit, regardless of whether services performed involve chiropractic manipulation or are limited to evaluation and management. If medical treatment is required after 24 chiropractic visits, a new physician who is not a chiropractor must be selected.
If you need help verifying an address or scheduling an appointment, you may contact a Medical Access Assistant toll free at 800-440-5020, 7 a.m. – 8 p.m. Pacific, Monday through Saturday.
If you have other concerns such as a complaint or question about the ZMPN, or for help with an MPN Independent Medical Review, you may call the ZMPN Contact at 818-704-3839 (Provider Group).
All other states: Provider directories for all other states are not available online. To receive a directory, please complete our Medical Provider Request Form.
