Medi-Cal Certified Eligibles - Recent Trends 

Recently, the Medi-Cal program has undergone substantial change. Individuals eligible for Medi-Cal residing in rural counties have been shifted from Medi-Cal's traditional Fee-for-Service (FFS) delivery system to Managed Care plans. Children were transitioned from the Healthy Families Program (HFP) into Medi-Cal, and the Patient Protection and Affordable Care Act (ACA) has brought in millions of new Medi-Cal enrollees since December 2013.

The implementation of the ACA has heightened interest in the Medi-Cal program. Medi-Cal's enrollment has grown significantly and stands at approximately one-third of California's population. Policymakers, stakeholders, and researchers are interested in enrollment trends, the demographic make-up of the enrollees, and various subpopulations within Medi-Cal's diverse overall population. To help answer the myriad of questions surrounding Medi-Cal's changing enrollment and demographic trends, RASD has created the following tools to help describe the Medi-Cal population and identify many unique subpopulations of interest:

  • Medi-Cal at a Glance presents a one-page snapshot of Medi-Cal certified eligibles during the most recent reportable month by basic demographic and administrative characteristics.
  • Fast Facts present a high-level overview of Medi-Cal certified eligibles by basic demographic and administrative characteristics.
  • Summary Tables allow users to examine the Medi-Cal certified eligible population by various demographics. 
  • Pivot Tables allow users to examine the Medi-Cal certified eligible population by a number of dimensions and provide users additional flexibility to array data for their unique needs. 

Counting and Reporting Medi-Cal Certified Eligibles  

To determine the number of current enrollees, DHCS uses a special definition of Medi-Cal beneficiaries referred to as "certified eligibles." When working with the certified eligible counts, it is important to consider whether the count is "preliminary" (referring to counts which are expected to grow from updates in subsequent months) or "final" (after 12 months of updates have been made to any given month). For an explanation of certified eligibles and reporting timeframes, refer to this brief informational presentation: "How Enrollment Statistics are Reported" (PDF)

Certified Eligible Counts - Summary Tables  

The following summary tables contain Medi-Cal certified eligible counts for the most current month of enrollmen. The data tables include counts by county and the following four aid code groups: ACA Expansion Adult Age 19-64, Parent/Caretaker Reliative and Child, Undocumented, and Other.


The following summary tables focuses more on the ACA Expansion Adult Age 19 to 64 aid category for the most current month of enrollment. The data tables include counts by county, age groups, race/ethnicity, and primary language.


The following summary tables show the most current month of enrollment for persons 65 and older. The tables include counts by county and aid code groups.

Pivot Tables  

The following data contain statewide certified eligible counts (both preliminary and final) for the most recent 48 months. Classification and filtering variables included in the Statewide Pivot Table are Month of Eligibility, Aid Code, and Delivery System. Filtering variables included in the County Pivot Table include Month of Eligibility and County. The reported measure for both tables is the Certified Eligible Count.
