1115 Waivers Explained: What They Mean for Your Coverage
An 1115 waiver is a federal authorization that lets a state temporarily bend or bypass certain rules in its Medicaid program, so long as the experiment is expected to advance the core goals of Medicaid-like expanding access, improving health outcomes, or streamlining care while keeping costs roughly the same for the federal government. These "demonstration projects" are named after Section 1115 of the Social Security Act and are approved by the U.S. Secretary of Health and Human Services after close review by the Centers for Medicare & Medicaid Services, or CMS.
What 1115 Waivers Actually Do
An 1115 waiver gives a state the freedom to test new coverage structures, eligibility rules, benefit packages, delivery systems, and financing arrangements that would otherwise be illegal under normal federal law. For example, a state might use a 1115 waiver to extend Medicaid expansion to groups that were previously ineligible, cover innovative mental-health or substance-use services, or experiment with community-engagement requirements such as work reporting.
Because Medicaid is a federal-state partnership, any change to how federal dollars are spent must still meet the requirement of being "budget neutral" to the federal government over the waiver period. In practice, this means that projected federal Medicaid spending under the 1115 waiver should not exceed what the federal government would have paid if the state had continued operating under standard rules.
Common Types of 1115 Waiver Designs
States have used 1115 waivers in several recurring ways, each of which targets a different part of the Medicaid program. Some of the most common models include:
- Medicaid expansion demonstrations that extend coverage to low-income adults above the normal income limits, often with premiums or cost-sharing rules that go beyond standard federal rules.
- Behavioral health and substance-use disorder demonstrations, such as Illinois' Behavioral Health Transformation Waiver, which added residential and inpatient treatment, case management, and supportive employment services for people with mental-health or addiction diagnoses.
- Health-related social needs pilots that fund non-medical services like housing assistance, food programs, transportation, and violence-prevention initiatives for high-risk Medicaid enrollees.
- Delivery-system reforms such as value-based payment models, medical-home programs, and care-coordination initiatives designed to reduce hospital readmissions and prevent costly crises.
Across all these models, the underlying premise is the same: the state proposes a concrete pilot project with measurable goals, and CMS approves it only if the design is likely to advance-or at least not undercut-the objectives of Medicaid.
How a 1115 Waiver Gets Approved
The 1115 approval process is deliberate and multi-layered, designed to balance state innovation with federal oversight and public input. First, the state drafts a detailed 1115 wavier application that spells out the proposed changes, eligibility criteria, benefit structure, financing plan, and evaluation strategy.
- The state holds at least a 30-day state public comment period, including public hearings, to gather feedback from stakeholders, providers, advocacy groups, and enrollees.
- After revising the application in light of comments, the state submits it to CMS, which then checks for completeness and posts a 30-day federal public comment window.
- CMS reviews the proposal for alignment with Medicaid goals, budget neutrality, and consistency with broader federal policy, then issues a decision letter that specifies which federal rules are waived or modified and under what conditions.
Recent federal guidance has tightened standards for certain types of 1115 waivers: for example, in 2025 CMS signaled it would not extend 1115 authority for new designated state health program or designated state investment program funding beyond the limits already set in statute. This reflects a broader push to ensure that demonstrations remain truly experimental and not permanent workarounds.
Real-World Examples and Dates
Illinois' Healthcare Transformation Waiver is one of the most frequently cited modern examples. The original 1115 Behavioral Health Transformation Waiver was approved in 2018, focused on expanding residential and inpatient treatment for substance-use disorders and supporting employment services. By 2023, the state had phased out the initial iteration and applied for a five-year extension that added explicit funding for health-related social needs, including housing, transportation, and violence-prevention services.
CMS approved the Illinois Healthcare Transformation Waiver extension in July 2024, explicitly authorizing services such as pre-release support in carceral settings and non-medical transportation for Medicaid enrollees in managed care. Elsewhere, states such as Arkansas and Kentucky have used 1115 waivers to implement community-engagement requirements (often called "work requirements") for some Medicaid adults, although court and policy shifts have led several of those experiments to be modified or rescinded over time.
Impact on Your Health Coverage
When a state operates under a 1115 waiver, the rules you must follow to keep your Medicaid coverage can change in important ways. In some states, 1115 experiments have led to:
- Broader eligibility and more people enrolled, especially low-income adults who might not otherwise qualify.
- New covered services, such as intensive mental-health treatment or wrap-around social supports, for specific priority populations.
- Added enrollment requirements, such as premium payments, work or volunteer reporting, or participation in health-education programs.
Conversely, some analysts estimate that certain 1115-driven changes-particularly strict work or activity requirements-have placed tens of thousands of current Medicaid enrollees at risk of losing coverage due to non-compliance, even though the stated goal of the waiver was to "promote program objectives." These trade-offs highlight why the structure of a specific 1115 waiver matters a great deal for how stable and generous your coverage actually feels.
1115 Waivers vs. Other Medicaid Tools
It's easy to confuse 1115 waivers with other federal tools states use to modify Medicaid rules, but they are distinct. A 1115 demonstration is an experimental project that must be budget neutral and usually runs for a limited period; by contrast, a standard state plan amendment can make smaller, non-experimental changes to coverage or payment that still fall within existing federal rules.
Another key distinction is with 1332 "innovation waivers," which operate in the ACA marketplace instead of Medicaid and allow states to reshape private insurance rules such as premium subsidies or benefit design. 1115 waivers are focused squarely on the Medicaid program and related health-related social-needs pilots, whereas 1332 waivers sit in the realm of commercial and marketplace coverage.
Illustrative 1115 Waiver Comparison Table
| Waiver Type / Example | Core Focus | Typical Duration | Key Feature |
|---|---|---|---|
| Illinois Healthcare Transformation Waiver (1115) | Mental-health and substance-use treatment plus health-related social needs | Initial 5 years; renewed through 2028-2029 | Includes pre-release services, non-medical transportation, and violence-prevention interventions. |
| Arkansas Premium-Assistance Waiver (1115) | Medicaid expansion via marketplace plans | Roughly 5-year initial period; extended with modifications | Enrolled adults received Medicaid dollars to buy private plans on the ACA marketplace. |
| Massachusetts "Global Compact"-style demonstrations | Delivery-system and payment reform | 5-year cycles; multiple extensions | Capitated payments to regions and incentives tied to quality and cost metrics. |
Key Benefits and Risks for Patients
For many enrollees, a well-designed 1115 waiver can mean more robust, tailored care. Behavioral-health and social-needs expansions, for instance, may reduce emergency-department visits and hospitalizations by addressing underlying problems such as housing instability or substance-use disorders.
On the other hand, 1115 designs that introduce complex eligibility tracking, reporting burdens, or new financial requirements can increase the risk of coverage gaps. Some health-policy organizations estimate that even modestly strict reporting rules can lead to coverage loss for several percent of the targeted population, especially in low-income or rural communities with limited digital or transportation access.
How 1115 Waivers Are Monitored
Once a 1115 waiver is in place, states are required to monitor and report on outcomes, usually on an annual basis. These evaluation requirements include drafting annual reports that detail enrollment trends, cost patterns, quality metrics, and any observed changes in access or health outcomes, which are then reviewed by CMS and posted on the state's website.
Federal and state policymakers often use these evaluations to decide whether to extend, tighten, or terminate specific 1115 experiments. For example, recent guidance from CMS in 2025 indicated that the agency would not extend 1115 authority for expanded continuous eligibility or workforce-investment initiatives beyond statutory limits, signaling a more cautious stance toward certain ambitious social-investment models.
Helpful tips and tricks for 1115 Waivers Explained What They Mean For Your Coverage
What is a 1115 waiver?
A 1115 waiver is an experimental project authorized under Section 1115 of the Social Security Act that allows a state to temporarily waive or modify certain federal Medicaid rules, as long as the demonstration is likely to promote the objectives of the Medicaid program and remains budget neutral to the federal government.
Who approves 1115 waivers?
The U.S. Secretary of Health and Human Services grants 1115 waivers after a detailed review by the Centers for Medicare & Medicaid Services, or CMS, which evaluates the objectives, financing, and public-input process of each state's proposal.
How long do 1115 waivers last?
Section 1115 demonstrations are typically approved for an initial five-year period and can be extended for up to three to five additional years, depending on the populations served and the results of ongoing evaluations.
Do 1115 waivers cost the federal government more?
No: by design, 1115 waivers must be "budget neutral," meaning that projected federal Medicaid spending under the waiver should not exceed what the federal government would have spent if the state had continued operating under standard rules.
Can a 1115 waiver strip people of coverage?
Yes, depending on how it is structured. Some 1115 designs that add work requirements, premium obligations, or complex reporting rules can lead enrollees to lose Medicaid coverage if they fail to comply, even though the waiver's stated goal is to promote program objectives.
How can I tell if my state uses a 1115 waiver?
You can check your state's Medicaid agency website or search for "Section 1115 demonstration" alongside your state name; many states publish a dedicated page describing their current 1115 waivers, including covered services, eligibility criteria, and implementation dates.
Are 1115 waivers only about Medicaid expansion?
No. While many states have used 1115 waivers to broaden Medicaid expansion, these demonstrations also cover behavioral-health reforms, delivery-system innovations, and health-related social-needs pilots such as housing and transportation support.
Do 1115 waivers affect other programs like Medicare or CHIP?
1115 waivers primarily apply to Medicaid, but some states have also used them for the Children's Health Insurance Program (CHIP), especially when designing demonstration projects that serve children and families.
What happens when a 1115 waiver ends?
When a 1115 waiver expires and is not renewed, the state must revert to standard federal Medicaid rules for the affected populations and services, unless separate legislation or a different federal authority preserves those changes.
Are 1115 waivers controversial?
Yes, they are often contentious because they can both expand coverage and services for some groups while imposing new requirements or restrictions that may reduce coverage for others, particularly vulnerable or low-income populations.
