King County Jails Start Billing Medicaid for Help at Release

The jails in Seattle and Kent have started billing Medicaid for the work of getting people ready to leave. Washington is one of 22 states holding a federal waiver that lets the program pay for case management, substance use treatment scheduling and a 30-day supply of medication handed over at the door. The services must be delivered in the 90 days before someone walks out, and the moment they walk out is when the danger peaks — research published in the New England Journal of Medicine found former inmates face sharply elevated death rates in the first two weeks after release, with overdose the leading cause.

King County's billing began under a pilot that will need renewing, and the scale of the change is in the arithmetic. Jail Health Services, the arm of Public Health — Seattle & King County that provides medical care behind the bars, previously funded release planning for a small slice of the sickest patients, roughly 15 percent of the population. Under the new billing arrangement, the vast majority of the 1,400 people held in the two jails can now qualify.

For people with opioid use disorder, that difference is concrete. Most arrive with no supply of their medication and no connection to a prescriber, and the hours after release are the ones that decide whether a person reaches care or a dealer. "Just completely to the streets, in a town I didn't know," CaSandra Adams told KUOW, describing a decade of cycling through local jails on offenses tied to her addiction. She listed what she had on release: "clothes inappropriate to the weather, no ride, no money, no phone, no ID, no nothing. Just having to survive, figure it out."

Adams now works as a peer advisor for the county's jail reentry initiative, helping design the process she once went without.

What the waiver money buys

The reimbursable list is narrow and practical. Case management, scheduling of substance use disorder treatment, and that 30-day medication supply with medical supplies included.

Megan Murphy, who manages the initiative, said the money changes what staff can promise. "We can leverage non-local dollars to pay for services in the jail," she said. The requirement attached to the money is what turns a discharge note into a handoff: "This comes with a requirement for release planning for all eligible people in addition to that warm handoff to an appropriate service provider to continue those services."

Denotra McBride, director of the county's Jail Health Services division, described the operational shift as something the division has never done. The jails had never billed insurance at all, and connecting people to their next step in care is a new role for nurses and clinicians whose job had been treating what walked in the door. "What the Medicaid waiver actually offers," she said, is "actually supporting individuals that are releasing back into the community," with "warm handoffs in such a way that they can actually connect to a community provider."

A decade of groundwork, then a phase-in

None of this started this month. State lawmakers changed the rules in 2016 so that being booked into jail no longer stripped a person's Medicaid enrollment, an administrative churn that used to force people to reapply for coverage on release. In 2025 the Washington State Health Care Authority began phasing in the reentry benefit for eligible youth and adults at participating jails and prisons, and more than 40 facilities are now taking part.

The state awarded nearly $44 million in federal funds in the program's first year, mostly for capacity building and the information technology that billing requires. As of August 2026, participating facilities had been reimbursed for $3 million in pre-release services — a gap that says as much about the speed of implementation as about the size of the eligible population. Youth held in King County's juvenile detention facility sit in a separate pilot that goes further still, letting them keep full Medicaid benefits through their entire stay rather than only before release. A public health spokesperson, James Apa, told KUOW the facility can provide continuous medical, behavioral health, dental and care coordination without a break in coverage, and can draw up to $2 million under that pilot.

The medication gap that remains

Billing Medicaid is not the same as offering treatment. The county is also expanding what its jails can prescribe, and that work is on a slower clock. Within the next year the Seattle and Kent jails will let people start methadone on site, and will widen access to long-acting injectable buprenorphine for anyone medically eligible — a change McBride said will be fully scaled up by January 2027.

That expansion sits inside a broader county push. Executive Girmay Zahilay's executive order on homelessness, addiction and incarceration, issued in March, made jail health one of the levers. Nationally, most people in state prisons meet the criteria for drug dependence or abuse, and jails have historically been the place where that need goes untreated — a person can be stabilized on medication in the community, booked, lose the prescription, and be released with a tolerance that has dropped and no tolerance for the dose they used to take.

The evidence for the prerelease model is not new. A 2022 study in JAMA Network Open found that coverage for pre-release planning led more people with substance use disorder to reach outpatient care after they got out.

The clock, and the states that paused

The federal reentry funding is a pilot with less than two years left on its current authorization, and jail health staff say they are counting on Washington to secure an extension. That is not guaranteed anywhere. Three states — Oregon, Rhode Island and Michigan — shelved or withdrew reentry plans earlier this year as budget and eligibility changes required by the last federal reconciliation law hit their Medicaid programs, a reversal this site reported in July. Nineteen states held approval at that point; four had actually switched their programs on.

King County is now one of the places where the concept is past the press release and into billing. What patients get is not a cure or a bed. It is a prescription in hand, a scheduled appointment and a person on the other end of a warm handoff — the things Adams said would have changed the shape of her release, back when she was leaving with nothing. "You really need people," she said. "To do this alone is impossible."

People looking for medication-assisted treatment after a period of incarceration, or for opioid addiction treatment more generally, can compare options by level of care before the first appointment.
