California's CalAIM initiative launched Enhanced Care Management (ECM) and Community Supports (CS) programs in January 2022, representing the most significant expansion of Medi-Cal benefits in decades. Two years into implementation, the data tells a story of meaningful progress alongside persistent challenges — and offers important lessons for the next phase of the program.
ECM in 2022: First-Year Implementation Data
The first year of ECM implementation was characterized by rapid enrollment growth in some counties and significant access gaps in others. By the end of 2022, approximately 75,000 Medi-Cal members were enrolled in ECM statewide — a substantial number, but well below the estimated 1.5 million members who meet eligibility criteria for the program.
The gap between eligible and enrolled members reflects several implementation challenges: limited lead entity capacity in many counties, the complexity of the enrollment and attribution process, and the time required to build the care coordination infrastructure needed to serve high-need members effectively. Plans that invested early in lead entity network development and enrollment support infrastructure showed significantly higher ECM penetration rates than those that relied on passive enrollment processes.
The demographic profile of enrolled ECM members in 2022 closely matched the target population: high rates of homelessness, serious mental illness, and substance use disorders; disproportionate representation of Black and Latino members; and high prior-year healthcare utilization including multiple ED visits and inpatient admissions. This suggests that the targeting mechanisms — including high-cost high-need flags and care manager referrals — are functioning as intended.
Community Supports: Utilization and Access Patterns
Community Supports utilization in 2022 was concentrated in a small number of service categories. Housing transition navigation, housing deposits, and housing tenancy and sustaining services accounted for the majority of CS expenditure — reflecting both the high prevalence of housing instability among ECM-eligible populations and the relative maturity of housing service networks in California's managed care ecosystem.
Several CS categories showed very limited utilization in the first year: community transition services, personal care and homemaker services, and medically tailored meals outside of specific high-need populations. In many cases, low utilization reflected not a lack of member need but a lack of provider network capacity — plans had not yet contracted with sufficient providers to make these services accessible across their service areas.
Demographic Insights and Equity Implications
The 2022 data reveals important equity patterns in ECM and CS access. Members in urban counties — particularly Los Angeles, San Diego, and the Bay Area — had significantly higher ECM enrollment rates than members in rural counties, reflecting the concentration of lead entity capacity in urban areas. This geographic disparity is one of the most significant equity challenges in CalAIM implementation, and one that DHCS has identified as a priority for the next phase of the program.
Language access is another significant equity dimension. Members with limited English proficiency — particularly Spanish-speaking members — showed lower ECM enrollment rates than English-speaking members with similar clinical profiles, suggesting that language barriers in the enrollment and care coordination process are creating access disparities that targeted outreach and culturally competent lead entities can address.
Early Outcome Signals
While it is too early to draw definitive conclusions about ECM's impact on health outcomes, the 2022 data contains several encouraging signals. Members enrolled in ECM for 6 or more months showed lower rates of ED utilization and inpatient admissions in the second half of the year compared to the first — a pattern consistent with the expected trajectory of effective care management intervention.
Members receiving housing-related Community Supports showed particularly strong outcome signals, with significant reductions in ED utilization and inpatient admissions following housing placement. This is consistent with a robust evidence base linking housing stability to reduced healthcare utilization — and provides early validation for CalAIM's investment in housing as a healthcare intervention.
