Imagine a Medi-Cal member working two part-time jobs. She meets the new federal work requirement. Her income remains low enough to qualify for coverage. But one employer does not appear cleanly in an electronic data match.
A notice arrives while she is working. She now has to figure out whether the rule applies to her, locate pay stubs, prove her hours or an exemption, complete her renewal, respond to any missing-information request, and do it all before a deadline.
She may be eligible in every substantive sense and still lose coverage because the process failed.
That is the operational challenge California now faces under H.R. 1. Under the current implementation timetable, work and community-engagement requirements begin January 1, 2027 and California’s federal eligibility changes begin as early as October 2026 for many adults ages 19 to 64 in the ACA expansion population. The federal framework generally requires 80 hours per month of employment, community service or qualifying work programs, half-time education, or equivalent earnings, with multiple exemptions. California’s Department of Health Care Services says six-month eligibility checks will begin March 1, 2027 for affected adults who previously generally renewed annually. [11]
The scale is difficult to overstate. California’s Legislative Analyst’s Office estimates that roughly 4.9 million Medi-Cal members are in the population affected by twice-annual redeterminations and that approximately 3.5 million people could be subject to the work requirement after potential exemptions. The LAO estimates that the combined effects of community-engagement requirements and more frequent renewals could reduce coverage by about 2.1 million people by June 2028, compared with roughly 1.8 million in the administration’s estimate. [1]
Those numbers are forecasts, not destiny. In fact, one of the most consequential variables may be how California operationalizes the policy.
The Unwinding Already Showed us What Goes Wrong
California has been through a version of this challenge before. When pandemic-era continuous Medicaid coverage ended, the state had to redetermine Medi-Cal eligibility at enormous scale. Federal data analyzed by the Government Accountability Office show that California renewed 81.8% of completed redeterminations between March 2023 and September 2024. Importantly, 73.8% of renewals were completed ex parte—using available information rather than requiring the enrollee to provide new documentation. [5]
Those are meaningful accomplishments. But the same data contain a warning: 74.1% of California disenrollments were procedural, rather than findings that the individual was actually ineligible. A subsequent California Health Care Foundation analysis found that 268,533 people—15% of those initially disenrolled—were later reinstated after being determined eligible. [12]
That distinction matters. Medicaid churn is sometimes discussed as if it simply represents the system identifying people who no longer qualify. California’s own experience shows that a substantial share can instead reflect failure to complete the process: missing information, paperwork not returned on time, or another procedural barrier. [12]
The history of Medicaid work requirements offers an additional caution. When Arkansas implemented a work requirement in 2018, a peer-reviewed New England Journal of Medicine study found significant losses of health coverage but no significant increase in employment. More than 95% of the population targeted by the policy appeared already to meet the requirement or qualify for an exemption; confusion and lack of awareness around reporting were common. Arkansas’s policy was different from the federal framework California must implement, but the operational lesson is important: when eligibility depends both on what someone does in the real world and on successfully proving it to a system, administrative design becomes a coverage policy in its own right. [7]
And the consequences extend beyond enrollment statistics. Research conducted during the Medicaid unwinding found that adults who exited Medicaid experienced greater problems accessing and affording care, while many who transitioned to other insurance experienced gaps in coverage. [13]
The Answer is Execution, not More Reminders
California is already moving in the right direction. DHCS’s implementation principles emphasize using data to confirm eligibility, reducing paperwork, simplifying six-month renewals, communicating in culturally appropriate language and partnering with counties, health plans and community organizations. [8] The administration has proposed using sources including state wage records, IRS data and third-party employment information to verify work activity, along with health information to help identify people who may qualify for exemptions. DHCS is also assessing technology vendors that could support implementation and Medicaid-system modernization. [9]
That should be the first layer of the strategy: when reliable data can establish eligibility or compliance without asking a person to prove it again, use the data.
But no data match will resolve every case. The last mile is where a different generation of technology could matter.
When electronic sources are insufficient today, a Medi-Cal member may need to produce a pay stub showing gross income, pay period, date and hours worked; an employer statement or tax return; or, if self-employed, a Schedule C or profit-and-loss statement. Members can renew online, by mail, over the phone or in person, with assistance from county workers and enrollment navigators. [10]
The problem is that “assistance is available” is not the same thing as “the task gets completed.”
A modern coverage-continuity system should be able to stay with a person across multiple sessions and channels; communicate in the person’s preferred language; understand what information is still missing; collect documents from a phone call; extract the relevant information; prepare the appropriate renewal packet; route ambiguous cases to a trained human; obtain required member approval through an authorized process; submit through approved channels; and continue tracking the case until renewal is confirmed or further intervention is required.
That is not autonomous eligibility determination. Counties remain responsible for determining eligibility. [14] It is workflow execution around eligibility: carrying more of the operational burden between “you need to renew” and “your coverage is confirmed.”
The difference is consequential because simply scaling the old outreach model—more letters, more robocalls, more text reminders—still leaves the hardest work with the person who has the least time to do it. The next generation of technology should not merely remind a member that a task exists. It should help the member complete the task, with humans supervising judgment, exceptions and trust-sensitive interactions.
The Operating Model Has to be Shared
The community-engagement requirement creates a second challenge. Some members will not simply have qualifying activity waiting to be verified.
Federal rules recognize several ways of satisfying the requirement, including employment, community service, qualifying work programs and education, as well as specified exemptions. [3] That means a truly member-centered implementation should do more than tell someone that verification failed.
With the member’s consent, the same navigation infrastructure could help identify whether an exemption applies and, where appropriate, connect someone to employment services, training, education, community-service opportunities or other qualifying pathways. This is an area where California’s health infrastructure and its workforce and community-service infrastructure should increasingly connect rather than operate as separate systems.
Meeting this moment will require more than incremental innovation. It demands a seismic shift toward visionary technology that can break down silos, connect traditionally separate systems and fundamentally reimagine how health and social infrastructure work together.
Counties administer eligibility. [14] Health plans have established member-engagement infrastructure. Health systems and federally qualified health centers encounter people in the course of receiving care, including people for whom a coverage interruption can become a care interruption. Community-based organizations bring local relationships, benefits navigation and connections to employment and social services. DHCS itself has called for coordination among members, counties, health plans and community partners as H.R. 1 is implemented. [8]
Technology can become the connective execution layer across those actors.
The wrong response would be four parallel outreach campaigns: one from the county, another from the plan, another from the health center and another from a community organization, each telling the same person to go somewhere else to finish the work.
The better model is shared, closed-loop execution. Use authoritative data first. Engage only the unresolved cases. Maintain context across sessions so someone can pause between shifts and resume later rather than start over. Automate routine information gathering, document preparation, reminders and status tracking. Reserve human navigators and eligibility workers for ambiguity, exemptions, appeals, complex circumstances and moments where judgment or trust matters most.
And change what we measure.
Not just calls placed. Not just texts delivered. Not just portal logins.
Measure renewals completed without a coverage gap; procedural disenrollment; time to resolution; cases resolved without manual intervention; human minutes required per successful renewal; disparities in completion by language and geography; and successful connection to qualifying activities or exemptions where verification initially fails.
The goal is not better outreach. The goal is continuous coverage for people who remain eligible.
The Clock Has Started
This is not really a 2027 problem.
California’s federal eligibility changes begin as early as October 2026. The community-engagement requirement is currently scheduled for January 2027, and California says six-month eligibility checks will follow in March. DHCS has already stated that its implementation strategy is intended to reduce disruption through automation, simplified renewals, multilingual communication and collaboration with counties, plans and community partners. [15]
There is still litigation around elements of the federal work-requirement rule, but a federal judge declined in late July to preliminarily block implementation; the underlying challenge remains pending. For operators, that means the responsible course today is to prepare for the current implementation dates while remaining flexible as litigation and federal guidance evolve. [16]
The public and private sectors should organize around a simple principle:
No Californian who remains eligible for Medi-Cal should lose coverage because we failed to execute the administrative workflow.
The Medicaid unwinding gave us the warning. California now has better data, more capable technology and an opportunity to design the operational layer differently.
The promise of AI here is not that it can send more reminders. It is that, under appropriate government and human oversight, technology can increasingly carry the work between “you need to renew” and “your coverage is confirmed.”
For millions of Californians, that distinction may determine whether the next wave of Medicaid reform becomes a coverage cliff or a manageable transition.
