Medi-Cal Enrollment by Eligibility Group

This dataset includes the total number of individuals enrolled in Medi-Cal by eligibility group: Modified Adjusted Gross Income (MAGI), non-MAGI, and Children’s Health Insurance Program (CHIP). The groups are defined by the Centers for Medicare and Medicaid Services (CMS) Performance Indicators (CMSPI) reporting requirements. The Department of Health Care Services (DHCS) submits eligibility and enrollment data regarding Medicaid and CHIP monthly to CMS. The enrollment data represents enrollment totals as of 60 days after the eligibility month (indicated as “Reporting Period” in the dataset). CMS publishes the state total enrollments on the CMSPI website. The total enrollment comprises of individuals who are eligible for full scope Medi-Cal by MAGI – Child, MAGI – Adult, Non-MAGI Child, Non-MAGI Adult, and CHIP eligibility groups. DHCS does not report to CMS the total enrollment in limited scope Medi-Cal or state-only funded programs (indicated as the “Non-CMSPI” in the dataset).

Additional Limitations

Some presented eligible counts are considered preliminary and subject to change. Eligibility for Medi-Cal may occur retroactively and it may take time for eligibility determinations to be processed and reported to DHCS. As such, eligibility data is approximately 96% complete for the current month, 98% complete within one month, and over 99% complete within 2 months. Eligibility counts for a specific month are considered complete for statistical reporting purposes 12 months after the reporting month’s end.
