If you're running a treatment center in Wisconsin, South Carolina, Oregon, Oklahoma, Connecticut, Utah, or Iowa, you've felt it. Census dips that don't match your intake numbers. Patients who disappear mid-episode. Authorization denials that used to sail through. The Medicaid unwinding behavioral health Wisconsin South Carolina Oregon operators are experiencing isn't a 2023 news cycle anymore. It's a 2026 operational reality that's still reshaping payer mix, patient retention, and revenue models across these seven states.
This is the fourth article in our state-by-state Medicaid unwinding series. We're covering a geographically and ideologically diverse cluster of states where redetermination played out differently, and where the downstream effects on SUD treatment access are still unfolding. Oregon's coordinated care model creates unique complexity. South Carolina and Oklahoma have high uninsured baselines with limited safety nets. Wisconsin's BadgerCare structure drives distinct redetermination workflows. Connecticut and Utah operate tight managed care environments. Iowa's three-MCO system means different authorization rules depending on which plan your patient had.
Let's break down what happened in each state, what it means for your census today, and what you can do about it.
What Medicaid Unwinding Means in 2026 and Why It Still Matters
Medicaid continuous enrollment protections ended in April 2023. States began redeterminations immediately. By late 2024, most states had worked through their backlogs. But the operational and clinical fallout for behavioral health providers didn't end when the redetermination letters stopped going out.
Patients lost coverage mid-treatment. Some never re-enrolled even though they remained eligible. Others transitioned to Marketplace plans with different networks or higher cost-sharing. Many simply went uninsured and dropped out of care entirely.
The impact on SUD treatment census has been uneven but persistent. States that expanded Medicaid under the ACA saw larger absolute enrollment drops because they had more people enrolled to begin with. States that never expanded saw smaller percentage drops but higher rates of patients falling into coverage gaps with no commercial fallback. The broader federal policy environment in 2026 is compounding these challenges, making payer diversification and operational resilience more critical than ever.
Wisconsin: BadgerCare Redetermination Dynamics and SUD Coverage
Wisconsin did not expand Medicaid under the ACA. BadgerCare Plus covers adults up to 100% of the federal poverty level, with pregnant women and parents eligible at higher thresholds. This creates a coverage gap for adults earning between 100% and 138% FPL, who don't qualify for BadgerCare but may qualify for subsidized Marketplace plans.
Wisconsin's Department of Health Services reported that approximately 311,000 people lost BadgerCare coverage during the unwinding period. Many were children who aged out or families whose income fluctuated above eligibility thresholds. For SUD treatment providers, the key demographic was non-parent adults at or near 100% FPL, a population with high SUD prevalence and limited commercial insurance options.
BadgerCare's managed care plans (Anthem, Molina, Quartz, and UnitedHealthcare) each handle prior authorization and appeals differently. If a patient loses coverage mid-IOP, the authorization workflow resets entirely if they transition to a Marketplace plan or regain eligibility under a different MCO. Providers need real-time eligibility verification at every visit, not just at intake.
Wisconsin also has a robust county-based behavioral health system. Patients who lose BadgerCare may still access crisis services or outpatient care through county programs, but residential and PHP-level care often becomes inaccessible without Medicaid or commercial coverage.
South Carolina: High Uninsured Baseline and Limited Safety Nets
South Carolina did not expand Medicaid. Adult eligibility is limited to parents and caretakers earning less than 67% FPL, pregnant women, and people with disabilities. This means most non-parent adults with SUD have never been eligible for Medicaid in the first place.
The state's Medicaid redetermination process disenrolled approximately 338,000 people, primarily children and postpartum women. For SUD providers, the impact was less about adults losing coverage and more about the operational strain of serving a patient population that was already largely uninsured.
South Carolina has one of the highest uninsured rates in the country. Patients who lose Medicaid often have no commercial fallback. They stop showing up to IOP. They miss PHP sessions. They relapse and cycle back through detox without continuity of care. The state's Medicaid managed care plans (Healthy Blue, Molina, and Absolute Total Care) cover SUD treatment, but the pool of eligible patients is small to begin with.
For treatment centers in South Carolina, payer diversification means building sliding scale capacity, partnering with FQHCs, and developing self-pay models that don't just extract payment but actually retain patients through financial barriers. This is not a Medicaid unwinding problem. It's a structural coverage gap that unwinding made more visible.
Oregon: OHA Coordinated Care and the Most Complex Unwinding Environment
Oregon expanded Medicaid aggressively under the ACA. The Oregon Health Authority's coordinated care organization model integrates physical, behavioral, and dental care under regional CCOs. This makes Oregon one of the most progressive SUD policy environments in the country, but also one of the most operationally complex for providers navigating redetermination disruption.
Oregon disenrolled approximately 450,000 people from Medicaid during unwinding, one of the highest rates in the nation. Many were eligible but lost coverage due to procedural issues like outdated addresses or missed renewal paperwork. The state paused redeterminations multiple times to address processing backlogs, which prolonged uncertainty for providers trying to forecast census.
Each CCO (like Health Share of Oregon, PacificSource, or Trillium) has distinct authorization workflows, network requirements, and utilization management protocols. A patient who loses coverage with one CCO and re-enrolls with another mid-treatment may face entirely different prior auth requirements for the same level of care. If you're opening or operating a treatment center in Oregon, understanding OHA licensing and CCO contracting dynamics is essential to navigating this environment.
Oregon also implemented Measure 110, which decriminalized personal drug possession and directed cannabis tax revenue toward addiction services. This created a parallel funding stream outside traditional Medicaid, but unwinding still disrupted access for patients who relied on CCO-covered residential or PHP care.
Oklahoma: Conservative State with High SUD Prevalence and Coverage Gaps
Oklahoma expanded Medicaid via ballot initiative in 2021, later than most states. SoonerCare expansion brought coverage to adults up to 138% FPL, significantly increasing the number of people eligible for SUD treatment through Medicaid managed care plans (Aetna Better Health, Oklahoma Complete Health, and UnitedHealthcare).
The state disenrolled approximately 252,000 people during unwinding. Many were newly eligible expansion adults who lost coverage due to income verification issues or missed renewals. Oklahoma's redetermination process was fast and aggressive, with high procedural disenrollment rates compared to other expansion states.
For SUD providers, this created a whiplash effect. Census surged after expansion as newly eligible patients accessed residential and IOP care. Then unwinding hit, and many of those same patients lost coverage mid-episode. Oklahoma's managed care plans have tight authorization windows, and re-enrollment after disenrollment can take weeks, during which patients often disengage from treatment entirely.
Oklahoma also has a high prevalence of methamphetamine and opioid use disorders, with rural areas facing severe provider shortages. Patients who lose Medicaid in rural counties often have no other treatment options within driving distance. This isn't just a coverage problem. It's an access crisis that unwinding accelerated.
Connecticut: Tight Managed Care Networks and Mid-Episode Transitions
Connecticut expanded Medicaid and has relatively high enrollment compared to non-expansion states. HUSKY Health covers adults up to 138% FPL, and the state's managed care plans (Anthem and UnitedHealthcare) have established behavioral health networks.
Connecticut disenrolled approximately 127,000 people during unwinding, a smaller absolute number than larger states but still significant for treatment centers operating in a tight payer environment. The state's managed care plans have strict network adequacy requirements and utilization management protocols, which means patients who lose coverage and transition to Marketplace plans may no longer be in-network with their current provider.
Mid-episode transitions are the operational killer here. A patient in week three of a six-week PHP program loses HUSKY coverage, re-enrolls in a Marketplace plan with a different network, and suddenly your facility is out-of-network. You can continue care and bill the patient directly, pursue single-case agreements, or discharge prematurely. None of these options are good.
Connecticut providers need real-time eligibility checks, presumptive eligibility protocols for patients in redetermination, and relationships with multiple payers to absorb transitions without disrupting clinical continuity.
Utah: Medicaid Expansion and Managed Care Authorization Workflows
Utah expanded Medicaid in 2020 with a work requirement waiver that was later removed. The state's Medicaid program covers adults up to 138% FPL through managed care plans (Healthy U from Molina and UnitedHealthcare).
Utah disenrolled approximately 152,000 people during unwinding. The state's redetermination process was relatively efficient, but procedural disenrollments still occurred, particularly among patients with unstable housing or inconsistent mail access, common in the SUD population.
Utah's managed care plans have specific authorization requirements for SUD treatment, particularly for residential and PHP levels of care. Molina and UnitedHealthcare each use different utilization review criteria, and patients who lose coverage with one plan and re-enroll with another may face different authorization timelines and approval standards.
For treatment centers, this means building authorization workflows that account for plan-specific requirements and maintaining relationships with both MCOs to expedite re-authorizations when patients transition between plans.
Iowa: Three-MCO Medicaid System and Authorization Complexity
Iowa's Medicaid program is entirely managed care, operated by Iowa Total Care, Molina, and UnitedHealthcare. This creates a complex authorization environment where different patients at the same facility may have entirely different prior auth requirements depending on which MCO they're enrolled with.
Iowa disenrolled approximately 145,000 people during unwinding. The state's redetermination process moved quickly, and many patients lost coverage due to procedural issues rather than true ineligibility. For SUD providers, this meant patients in IOP or PHP suddenly losing coverage mid-episode, with re-enrollment timelines that varied by MCO.
Each of Iowa's three MCOs handles redeterminations and re-enrollments differently. Iowa Total Care may process a re-enrollment and issue a new authorization within a week, while UnitedHealthcare might take three weeks. Molina's utilization review criteria for extended IOP services differ from the other two plans, which affects step-down planning for patients transitioning from PHP.
Iowa providers need MCO-specific authorization workflows, real-time eligibility verification systems, and contingency protocols for patients who lose coverage mid-treatment. This is not a one-size-fits-all state.
Operational Playbook: Protecting Census and Revenue Through Medicaid Redetermination
Here's what works across all seven states, adapted to your specific payer environment.
Real-Time Eligibility Verification
Check eligibility at every visit, not just at intake. Medicaid coverage can lapse between sessions, and you need to know immediately when a patient's status changes. Use automated eligibility verification tools integrated with your EHR, or assign staff to run manual checks daily for all active patients.
Presumptive Eligibility and Coverage Gap Protocols
If a patient loses Medicaid but is likely eligible for re-enrollment or Marketplace coverage, don't discharge immediately. Implement a coverage gap protocol that allows continued treatment for 7-14 days while you help the patient navigate re-enrollment. Document medical necessity clearly to support any retrospective billing if coverage is reinstated.
Sliding Scale and Self-Pay Models That Actually Retain Patients
Sliding scale isn't charity. It's a revenue protection strategy. Patients who lose Medicaid and face a $200 IOP session fee will disappear. Patients who face a $40 sliding scale fee based on income may stay engaged. Build a sliding scale structure that covers variable costs and retains patients through coverage transitions.
Payer Mix Diversification
If your census is 80% Medicaid, you're operationally vulnerable to policy changes beyond your control. Diversify into commercial payers, EAP contracts, and self-pay models. This doesn't mean abandoning Medicaid patients. It means building financial resilience so you can continue serving them even when enrollment fluctuates. The 2026 federal policy landscape makes this diversification even more critical.
State-Specific MCO Relationships
In Iowa, Wisconsin, and other managed care states, your relationship with MCO care coordinators and utilization review staff directly affects authorization timelines. Build those relationships. Know who to call when a patient loses coverage mid-PHP and needs expedited re-authorization. This is operational infrastructure, not networking.
What This Means for Your Treatment Center Right Now
Medicaid unwinding isn't over. The redetermination letters may have stopped, but patients are still cycling through coverage losses, re-enrollments, and transitions between payers. Your census reflects this instability. Your authorization denials reflect this instability. Your revenue reflects this instability.
The states covered in this article span different political environments, eligibility thresholds, and managed care structures, but the operational challenge is the same: how do you maintain clinical continuity and financial stability when your patients' coverage is unpredictable?
The answer isn't to wait for policy to stabilize. The answer is to build operational systems that absorb volatility without disrupting care. Real-time eligibility checks. Presumptive eligibility protocols. Sliding scale models. Payer diversification. MCO relationships. These aren't aspirational goals. They're survival infrastructure for 2026 and beyond.
With federal funding streams under pressure and state Medicaid programs still adjusting post-unwinding, treatment centers that adapt operationally will maintain census. Those that don't will continue to see erosion.
Frequently Asked Questions
Is Medicaid unwinding still happening in 2026?
The formal redetermination period ended in most states by late 2024, but the operational effects are ongoing. Patients continue to lose and regain coverage as their circumstances change. States continue to process renewals on normal cycles. The instability created by unwinding didn't end when the redetermination backlog cleared.
How does Medicaid loss affect addiction treatment access?
When patients lose Medicaid, they often lose access to residential, PHP, and IOP care unless they have commercial insurance or can afford self-pay rates. Many disengage from treatment entirely during coverage gaps, increasing relapse risk and cycling back through crisis services. Treatment centers see census drops, authorization denials, and mid-episode discharges.
Which states handled redeterminations worst?
States with high procedural disenrollment rates, outdated contact information systems, and aggressive redetermination timelines saw the worst outcomes. Oregon, Florida, and Texas had particularly high disenrollment rates, many due to procedural issues rather than true ineligibility. Among the states covered in this article, Oklahoma and South Carolina had high procedural disenrollment rates, while Connecticut and Wisconsin processed renewals more efficiently.
What can treatment centers do when patients lose Medicaid mid-treatment?
Implement a coverage gap protocol. Check eligibility in real-time. Help patients navigate re-enrollment or Marketplace enrollment. Use presumptive eligibility to continue care for 7-14 days while coverage is resolved. Offer sliding scale rates based on income. Document medical necessity clearly to support any retrospective billing. Don't discharge prematurely if the patient is likely to regain coverage and clinically benefits from continued treatment.
How do I protect behavioral health revenue during Medicaid redetermination?
Diversify payer mix so you're not over-reliant on Medicaid. Build relationships with commercial payers and MCOs. Implement real-time eligibility verification. Develop sliding scale and self-pay models that retain patients through coverage gaps. Train staff on state-specific redetermination processes and re-enrollment pathways. Treat payer instability as an operational challenge you can plan for, not an external shock you can't control.
