On April 8, 2026, the Centers for Medicare and Medicaid Services (CMS) released critical new guidance. This guidance addresses federal matching funds for Medicaid and the Children’s Health Insurance Program (CHIP). Specifically, it implements a provision from the reconciliation bill passed in July 2025. The changes take effect on October 1, 2026. Therefore, healthcare providers and state Medicaid agencies must understand these updates without delay.
Overview of the New CMS Guidance
CMS issued a State Health Official (SHO) letter outlining significant restrictions on federal Medicaid and CHIP funding. The guidance targets certain noncitizen populations currently enrolled in full Medicaid or CHIP benefits. Furthermore, it sets clear deadlines and action steps for state agencies. Consequently, states must move quickly to comply before the October 1 deadline.
Who Remains Eligible for Federal Medicaid Funding
Noncitizen Categories That Retain Full Coverage
Not all noncitizens lose access to federally matched Medicaid coverage. CMS confirmed that three specific groups will continue to qualify for full benefits:
- Legal permanent residents
- Certain Cuban and Haitian immigrants
- Compact of Free Association (COFA) migrants lawfully residing in the U.S.
These groups can still receive full Medicaid and CHIP benefits with federal matching funds after October 1. Additionally, their eligibility remains stable under the new provision. This distinction is important for providers serving diverse immigrant communities.
Who Loses Full Medicaid and CHIP Benefits
Affected Noncitizen Populations
Starting October 1, 2026, several lawfully present noncitizen groups will lose federally matched full Medicaid and CHIP benefits. These groups include:
- Refugees
- Asylees
- Parolees
- Victims of trafficking
Currently, these individuals qualify as lawfully present noncitizens. However, the new law specifically restricts federal funding for their comprehensive coverage. This represents a major policy shift. Millions of noncitizens could lose full health coverage as a direct result. Moreover, providers serving these communities should prepare for patient volume and coverage changes.
What the Law Does Not Change
Immigration Eligibility Definitions Stay Intact
CMS drew a clear distinction in its guidance. The new provision does not alter the Personal Responsibility and Work Opportunity Act (PRWORA). That law defines immigration eligibility categories for public benefits. Those underlying definitions remain unchanged. Instead, the new rule simply limits when federal matching funds apply. It does not rewrite immigration rules or change classification criteria.
Furthermore, states face no mandate to offer state-only coverage. Where federal funding becomes unavailable, a state may choose to use its own funds. However, this option is discretionary—not required. States should consult legal counsel before deciding on optional state-funded programs.
Required State Actions Before October 1
Steps Every State Medicaid Agency Must Complete
CMS outlined mandatory steps for all states. Agencies must complete these tasks before the October 1 deadline. Here is what each state must do:
- Conduct eligibility redeterminations for all current enrollees in affected categories
- Update eligibility and verification systems to reflect new federal funding rules
- Revise managed care and financial claiming procedures
- Submit Medicaid and CHIP state plan amendments (SPAs)
These are not optional tasks. CMS expects full compliance on time. Therefore, state Medicaid agencies should begin internal planning and stakeholder coordination immediately. Delays in system updates could disrupt coverage transitions for thousands of enrollees.
Emergency Medicaid Protections Remain
Federal Funds Still Cover Emergency Services
One important protection stays in place under the new guidance. CMS confirmed that federal matching funds continue to cover emergency Medicaid. This applies to all noncitizens—including those who lose full benefit eligibility. Emergency Medicaid covers acute care in life-threatening situations. Consequently, affected noncitizens can still access emergency services with federal reimbursement support. Hospitals should document emergency Medicaid claims carefully to ensure proper reimbursement.
Key Takeaways for Healthcare Providers
What Hospitals and Health Systems Need to Know Now
These coverage changes directly affect hospitals and health systems across the country. Many patients in affected noncitizen categories may lose Medicaid coverage on October 1. As a result, providers could see a rise in uncompensated care costs. Moreover, emergency Medicaid reimbursement remains available for qualifying services.
Providers should take the following steps:
- Monitor state Medicaid agency announcements for updated eligibility rules
- Review patient populations to identify individuals in affected noncitizen categories
- Engage case management teams to support affected patients in finding coverage alternatives
- Track emergency Medicaid billing to protect reimbursement for qualifying visits
Staying informed now helps hospitals avoid financial disruptions later. Additionally, proactive outreach to affected patients builds trust and reduces care gaps.
