ACCESSING A KASIER PERMANENTE SPECIALIST: In order to treat with a Kaiser Permanente Specialist, the injured worker must first be evaluated by a Kaiser Permanente On-the-job (KPOJ) Occupational Medicine physician. The KPOJ physician will determine the appropriate Specialist, make the referral and clinic staff will assist to schedule the referral and appointment with the specialist within the MPN. To schedule an initial appointment with a KPOJ physician, call the preferred KPOJ clinic location phone number included in the MPN listing. You may also contact the MPN Medical Access Assistant line listed below for additional assistance.
