Medicaid Eligibility Restrictions Are Live: What Psychiatry Practices Need to Change in Their Billing Now

How Do the October 2026 Medicaid Changes Affect Psychiatry Billing?

As of October 1, 2026, federal Medicaid eligibility restrictions under H.R. 1 have removed coverage for certain immigrant populations, including refugees, asylees, and trafficking survivors. Psychiatric practices are disproportionately affected because these populations are among the highest utilizers of mental health services, particularly for PTSD, trauma-related anxiety, and depression treatment. Claims submitted for patients who lost eligibility on October 1 will be denied, and additional billing changes taking effect January 1, 2027, will reduce retroactive coverage from 90 days to 30 or 60 days and introduce cost-sharing that creates new patient payment collection challenges for ongoing therapy.

• Eligibility verification is now critical at every visit. Patients who were covered through September 30 may have lost Medicaid status on October 1. Running eligibility checks before each session prevents billing for patients who are no longer covered.
• Ongoing therapy creates compounding risk. Unlike episodic medical visits, psychiatric care involves weekly or biweekly sessions. A patient who lost coverage creates multiple denied claims before the practice discovers the coverage lapse.
• Revenue diversification protects the practice. Psychiatry practices with high Medicaid concentration should begin commercial payer enrollment to offset potential volume loss.

What Changed on October 1, 2026

H.R. 1, enacted July 4, 2025, restricts federal Medicaid eligibility for certain noncitizen populations effective October 1, 2026. Starting on that date, Medicaid coverage is limited to U.S. citizens, U.S. nationals, lawful permanent residents, certain Cuban and Haitian entrants, and Compact of Free Association (COFA) migrants. Immigration statuses that previously qualified, including refugees, asylees, humanitarian parolees, and survivors of trafficking or domestic violence, no longer qualify for federally funded Medicaid in most states.

The NY State of Health portal published implementation guidance on October 6, 2026, confirming that affected individuals are being transitioned off coverage. Other states are implementing similar transitions, though the timeline and communication approach vary. Some states may fund coverage through state-only dollars for affected populations, but those programs are not guaranteed and typically reimburse at different rates.

For psychiatric practices, this is not a distant regulatory change. It is operational right now. Patients who were on your schedule last month with active Medicaid coverage may present this month without it. The most common issue we see providers run into during eligibility transitions is discovering the coverage loss only after multiple sessions have been delivered and billed. In psychiatry, where treatment is ongoing rather than episodic, this pattern creates a cascade of denied claims that can take weeks to identify.

Why Are Psychiatric Practices Hit Harder Than Other Specialties?

Psychiatry and behavioral health have one of the highest Medicaid utilization rates of any medical specialty. According to data from the Substance Abuse and Mental Health Services Administration (SAMHSA), Medicaid is the single largest payer for mental health services in the United States, covering approximately 27% of adults with mental illness. For psychiatric practices that serve refugee, asylee, and trauma survivor populations, Medicaid concentration can reach 40% or more of the patient panel.

The populations losing eligibility under H.R. 1 are also the populations most likely to need psychiatric care. Refugees and asylees present with high rates of PTSD, anxiety disorders, and depression related to displacement, persecution, and resettlement stress. Trafficking survivors frequently require intensive psychiatric treatment. These are not patients who present once for an acute issue. They are patients engaged in ongoing therapeutic relationships with weekly or biweekly sessions, often involving psychotherapy add-on codes and extended evaluation services.

The billing implication is compounding. A primary care practice might see a patient once and discover the coverage lapse on a single claim. A psychiatric practice delivering weekly 90837 sessions to a patient whose coverage lapsed on October 1 could generate four to six denied claims before the next eligibility check catches the problem. At a Medicaid reimbursement rate of roughly $108 to $123 per session (70 to 80% of Medicare’s $167 for CPT 90837), that is $432 to $738 in uncollectable revenue per patient per month.

What Psychiatric Practices Should Do Now

The changes are already in effect. Here is the billing action plan for psychiatric practices.

1. Run eligibility verification before every scheduled session. Do not rely on last month’s verification. Check Medicaid status through your clearinghouse or state portal before each appointment, especially for patients whose immigration status may be affected.
2. Audit your active patient panel for affected populations. Identify patients whose Medicaid coverage may have terminated on October 1. Flag their accounts in your practice management system so front desk staff verifies coverage at check-in.
3. Prepare for the January 2027 retroactive coverage reduction. Retroactive Medicaid coverage drops from 90 days to 30 days for expansion adults and 60 days for other populations starting January 1, 2027. Adjust your intake process to verify coverage before the first session, not after.
4. Build patient financial counseling into your workflow. Patients who lose Medicaid coverage need guidance on alternative coverage options. Having a process to connect them with marketplace plans, state-funded programs, or sliding-fee arrangements reduces the risk of lost appointments and unpaid balances.
5. Begin commercial payer enrollment to diversify your revenue. If Medicaid represents more than 30% of your practice revenue, start the credentialing process with commercial payers now. Standard timelines run 60 to 120 days.
6. Review your Medicaid managed care contracts. Some MCO contracts include volume-based rate adjustments. If your Medicaid patient count drops significantly, verify whether your contract terms are still favorable.

Billing Mistakes to Avoid During This Transition

Providers often come to us after eligibility transitions have already created a backlog of denied claims. The most common mistake in psychiatry is continuing to schedule and bill weekly therapy sessions without re-verifying coverage. Because psychiatric treatment is ongoing, a single eligibility lapse generates denied claims on every subsequent session until someone catches it. The financial exposure is far greater than in specialties where visits are episodic.

The second mistake is assuming that patients will inform the practice about their coverage change. Most patients do not know when their Medicaid eligibility has been terminated, especially immigrant populations who may face language barriers and limited familiarity with the U.S. insurance system. The responsibility for eligibility verification sits with the practice, not the patient.

A third mistake is waiting until the claims are denied to address the problem. By that point, the practice has delivered services it cannot collect on, and the administrative cost of reworking denied claims adds to the loss. In our experience matching providers with billing partners, the practices that weather eligibility transitions best are the ones whose billing company runs real-time eligibility checks as a standard workflow, not as a reactive measure after denials start accumulating. If your current billing partner is not doing this, it may be time to evaluate whether they have the behavioral health billing expertise this environment demands.

Protecting Revenue in a High-Medicaid Practice

One question we hear constantly from practice managers in psychiatry is whether they should reduce their Medicaid patient volume in response to these changes. The short answer is no, not proactively. The patients losing eligibility represent a subset of your total Medicaid panel. Most Medicaid patients, including U.S. citizens and lawful permanent residents, retain full eligibility. Dropping Medicaid entirely eliminates access to the patients who still need your services and removes a revenue stream that, while lower-reimbursing than commercial plans, still represents significant volume.

The better strategy is diversification. Adding commercial payer enrollment while maintaining Medicaid participation gives the practice a broader revenue base that absorbs the impact of eligibility changes in any single payer category. For psychiatric practices specifically, the 2027 Medicare payment changes add another reason to ensure your payer mix is not over-concentrated in any single source. A billing partner experienced in behavioral health can manage enrollment with multiple payers simultaneously and ensure that each payer’s specific psychiatric billing requirements, including telehealth modifiers, add-on code documentation, and time-based coding, are handled correctly from day one.
