Quarterly Medical Group Reports

Find a Calif Medical Group or MSO

Medical groups in the inventory are those that have at least 6 PCPs AND have a risk or non-risk contract directly with at least one HMO. Enrollment numbers are in ranges because some medical groups expressed concern about the use of specific enrollment numbers. The files below have been updated as of March 2017 unless otherwise noted.
