A quiet but sweeping federal change to Medicaid is reshaping what it looks like to walk out of jail in Santa Clara County. Instead of stepping through the gate with no prescriptions and a thin packet of paperwork, many people are now being seen by community providers inside the jail, sent out with a 30-day supply of medication, and given a treatment plan plus a case manager who will track them down in the neighborhood. Local health leaders say that continuity, not just coverage, is what could cut overdoses and repeat incarceration in the critical weeks after release.
As reported by The New York Times, the new policy lets Medicaid start paying for certain services up to 90 days before someone leaves jail or prison and continue afterward. The Times notes that Santa Clara County has been enrolling eligible detainees in Medi-Cal behind bars, arranging extended case management after release, and that local official Bob Jonsen called the expansion fantastic and long overdue.
How the waivers work
The shift runs through Section 1115 “reentry” demonstrations that give states permission to partially waive the long-standing "inmate exclusion" and cover a narrow set of health services before release. As outlined by KFF, states can ask for 30 to 90 days of pre-release Medicaid coverage for things like case management, medications for opioid use disorder, a 30-day supply of prescriptions at the door, and in-reach services from community providers, all subject to federal approval and strict reporting rules.
Why clinicians call it life-saving
Clinicians have been warning for years that the days right after release are uniquely dangerous. A foundational Washington state study found the risk of death in the first two weeks after release was nearly 13 times higher than for the general population. The main driver is untreated substance use disorders. The National Institute on Drug Abuse estimates that roughly two-thirds of people in prisons have an active SUD, and prerelease Medicaid services are designed to bridge that gap by keeping people on medications and tied into community care.
That Washington state work, published in The New England Journal of Medicine, along with follow-up public-health research, is part of why clinicians say early access to treatment and a named care manager can be the difference between a stable reentry and a fatal relapse.
California's local rollout
California was the first state to win federal approval and pilot prerelease Medi-Cal services, and it has been steadily expanding the effort since late 2024. The Department of Health Care Services reports that its Enhanced Care Management and Community Supports programs have already connected hundreds of thousands of Medi-Cal members with coordinated services. The Justice-Involved Reentry Initiative went live in October 2024, moved into state prisons in early 2025, and was operating in multiple counties by January 2026.
According to the department, the reentry program pairs those prerelease services with up to 12 months of post-release care coordination so people can keep medical appointments, stay on medications, and stick to housing plans. California's DHCS has been publishing quarterly data and implementation milestones as the rollout grows.
Big challenges remain
Policy trackers show that many states are now testing similar reentry waivers or have applications pending, but experts stress that a federal sign-off is only the starting line. Counties and community clinics still need funding, staff, and secure data connections with jails and prisons to make prerelease care a routine part of release planning. As KFF and state reports note, the real test will be whether there is enough technical assistance, provider capacity, and reinvestment to turn this new coverage into fewer overdoses and fewer people cycling back into custody.
For now, local officials say the measure of success is surprisingly simple: do people step out of jail with their medications and a clinic appointment, or with nothing at all. County leaders in the Bay Area say that when the handoff works, it can interrupt a dangerous chain of events in those fragile first weeks home, which is exactly what many families have been waiting for.
