Medicaid Is Changing: What IDD Providers Should Watch in 2026

If you run residential services, a day program, supported employment, respite, or another community-based program, Medicaid is not an abstract policy issue. It pays for DSP hours, transportation, clinical support, supervision, and the everyday work required to keep services running.

A federal budget law signed in July 2025 changes how states fund Medicaid and how some adults keep their coverage. The changes will roll out over several years, with several important provisions beginning in 2027. Federal Medicaid spending is now projected to be about $911 billion lower over ten years than it would have been under the prior law.

That does not mean every IDD provider is getting an immediate rate cut. It does mean states will have less room in their Medicaid budgets, and every state will make its own decisions about how to respond. Providers should be watching for changes to rates, waiver capacity, authorizations, eligibility, and payment practices.

Where Providers May Feel the Pressure

Rates may fall further behind the cost of providing services

The law limits some of the tools states use to fund their share of Medicaid. Beginning in October 2026, states will face new restrictions on provider taxes, which many states use to bring additional federal matching dollars into their Medicaid programs. Most Medicaid expansion states will face further limits beginning in late 2027.

Existing taxes on ICF/IID providers are protected from one of the major phase-downs in the law. That is important, but it does not fully insulate IDD services. A state that loses funding elsewhere in its Medicaid program still has to balance the overall budget.

For a community provider, that pressure may look less like a dramatic announcement and more like a rate increase that never comes. When reimbursement stays flat while wages, insurance, transportation, food, and other costs rise, a rate freeze is a cut in practical terms. It can mean more open shifts, fewer admissions, a closed program, or fewer service hours available to the people who need them.

Payment changes that now focus on hospitals could reach HCBS later

The law also limits certain extra payments that states direct through Medicaid managed care. The limits currently focus on hospitals, nursing facilities, and some services at academic medical centers—not every community IDD service.

However, CMS has proposed extending similar limits to all services covered by these arrangements beginning in 2029. That broader proposal could include home- and community-based services. It is not final as of September 2026, but providers that receive enhanced or directed payments through a managed care plan should find out how those payments are structured and whether their state expects them to change.

Coverage paperwork may create service interruptions

Starting in 2027, some adults covered through Medicaid expansion will need to show that they are working, attending school, participating in a work program, or completing community service for at least 80 hours a month.

Many people with IDD will be exempt. The exceptions include people whose disability significantly limits daily activities, people who qualify under federal disability rules, and parents or family caregivers of a person with a disability.

The concern for providers is paperwork. A person can qualify for an exception and still lose coverage temporarily if the state does not have the right information, a renewal notice goes to an old address, or a form is not returned on time. Providers should not decide who is eligible, but they can help people and families recognize important notices, update contact information, reach an authorized benefits representative, and gather records when asked.

Some people will have to renew Medicaid twice a year

Adults covered through the Medicaid expansion group will generally have their eligibility checked every six months instead of once a year beginning in 2027. Not everyone receiving IDD services is enrolled through that group, but some are. Some DSPs and family members may be as well.

More renewals create more chances for a preventable coverage gap. That matters when an agency has already provided services, an authorization is tied to active eligibility, or an employee loses access to medication or health care and misses work.

Providers will have less protection when coverage is approved late

Medicaid has traditionally been able to cover eligible services delivered up to three months before a person applied. Beginning in 2027, that window becomes one month for Medicaid expansion applicants and two months for most other applicants.

For providers, the practical issue is unpaid care. If an application, renewal, or reinstatement is delayed, fewer past service dates may be covered. Eligibility checks, authorization follow-up, and quick escalation of a coverage problem will become even more important.

There Is Also a Possible New HCBS Opportunity

Beginning in July 2028, states will have a new option to create an HCBS waiver for people who need support but do not yet meet the state’s institutional level-of-care standard.

This could help people receive support earlier instead of waiting until their needs become more serious. But it is optional. Each state will decide whether to apply, what services to offer, who will qualify, and how the program will be funded. Providers should watch whether their state begins discussing this option and whether there is a role for existing community programs.

What This Could Look Like in Day-to-Day Operations

No one can predict the exact effect on an individual agency from the federal law alone. The state budget and the design of each waiver matter more. These are the signs operators should watch for:

• A planned rate increase is delayed, reduced, or removed from the state budget.
• Waiver openings slow down even while the waiting list continues to grow.
• Managed care plans add authorization steps or review service utilization more closely.
• People temporarily lose eligibility even though they still qualify.
• Claims are denied because coverage or authorization was not active on the service date.
• DSP recruitment gets harder because reimbursement cannot support competitive wages or benefits.
• Hospitals and other health providers reduce access, leaving IDD agencies to manage more health-related coordination and crisis risk.

These pressures would arrive on top of an existing workforce problem. ANCOR’s 2025 provider survey found DSP turnover near 40%, vacancy rates between 12% and 15%, and 62% of responding providers turning away new referrals because they did not have enough staff.

What IDD Providers Can Do Now

Know exactly where your Medicaid revenue comes from

List each major service, the waiver or state-plan program that pays for it, whether it is fee-for-service or managed care, and whether any part of the payment is a special or directed payment. This will tell you which state and federal changes actually matter to your organization.

Know your break-even rate

Calculate the reimbursement needed to cover a staffed hour or day of service, including wages, payroll costs, supervision, training, transportation, insurance, and required administrative work. Then model what a rate freeze or small reduction would mean for open positions, overtime, admissions, and program capacity. Concrete numbers are more useful than a general statement that funding is inadequate.

Give Medicaid renewals a clear owner

Decide who in your organization watches for eligibility problems, who contacts the person or authorized representative, and who escalates an issue to the state or managed care plan. Make sure contact information is current and start follow-up before a renewal deadline, not after a claim is denied.

Track the impact of staffing and funding gaps

Keep simple, consistent records of vacancies, overtime, declined referrals, unused authorized hours, service interruptions, delayed hospital discharges, and programs operating below capacity. These are the facts state officials and provider associations need when rate and waiver decisions are being made.

Follow your state budget, not just national headlines

The federal law sets the pressure, but state decisions determine the local result. Follow your state Medicaid agency, governor’s budget, legislative hearings, waiver amendments, rate notices, and managed care communications. Your state provider association can often translate those developments faster than a national news story can.

Questions Worth Asking Your State or Managed Care Plan

• Does the state expect the federal changes to affect IDD rates, waiver slots, or planned rate increases?
• Are any of our payments funded through a state-directed payment arrangement?
• How will the state identify people with disabilities and family caregivers who are exempt from the new work requirements?
• What is the fastest way to correct an eligibility closure made because information was missing?
• What happens to an existing service authorization during a temporary eligibility gap?
• Is the state considering the new 2028 HCBS waiver option?
