Participating physician groups (PPGs) that are delegated for credentialing must ensure that members are not served by any provider excluded from program participation. PPGs may check the exclusion lists on the Department of Health and Human Services (DHHS) Office of the Inspector General (OIG) website at oig.hhs.gov under Exclusions and the Department of Health Care Services (DHCS) Medi-Cal website at www.medi-cal.ca.gov under References>Suspended and Ineligible Provider List. New lists are published each month and the former lists remain. Providers excluded from program participation and providers that have been reinstated are included on the lists. Health Net recommends that PPGs check the lists each month.
