Illinois Medicare & Medicaid Policy

Medicare and Medicaid both provide publicly financed health coverage, but their governing structures differ substantially. Understanding which level of government controls a policy decision is essential when evaluating legislation, regulations, funding changes, reimbursement policy, or coverage requirements.

Medicare: Primarily a Federal Program

Medicare is principally governed and administered by the federal government through the Centers for Medicare & Medicaid Services. Federal law and CMS policy establish eligibility rules, covered benefits, payment systems, beneficiary cost-sharing requirements, and standards for participating providers and health plans.

Medicare coverage generally includes:

• Part A: Hospital and certain institutional services

• Part B: Physician, outpatient, and other medical services

• Part C: Medicare Advantage coverage offered by private plans operating under federal contracts

• Part D: Outpatient prescription-drug coverage offered through federally regulated private plans

Although states do not establish the core Medicare benefit, Illinois agencies still have supporting roles. These include regulating insurance matters within state authority, licensing healthcare professionals and facilities, providing beneficiary counseling, coordinating Medicaid assistance for qualifying beneficiaries, and administering programs for people eligible for both Medicare and Medicaid.

Medicaid: A Federal-State Partnership

Medicaid is jointly financed and governed by the federal government and participating states. Federal law establishes mandatory coverage requirements, beneficiary protections, financing rules, and other national standards. CMS reviews state Medicaid plans, waivers, program amendments, managed-care arrangements, and compliance with federal requirements.

Within that framework, Illinois administers its Medicaid program primarily through the Department of Healthcare and Family Services. State responsibilities include:

• Determining eligibility under federal and state requirements

• Administering applications, renewals, notices, and appeals

• Selecting optional benefits and covered services

• Establishing many provider reimbursement methodologies

• Contracting with and overseeing Medicaid managed-care organizations

• Seeking federal approval for state-plan amendments and waiver programs

• Coordinating Medicaid with behavioral health, long-term care, public health, and other state services

• Requesting and appropriating the state funding needed to draw available federal Medicaid funds

Illinois policy choices must remain consistent with federal law and approved federal authorities. Significant changes may require legislation, state appropriations, administrative rules, a Medicaid state-plan amendment, a federal waiver, or some combination of these actions.

Where Federal and State Decisions Intersect

The federal-state structure means that a federal policy change rarely operates in Illinois through federal action alone. Illinois may need to revise eligibility systems, administrative rules, managed-care contracts, provider instructions, customer notices, application procedures, or its state budget before a federal requirement can be fully implemented.

Conversely, Illinois may pursue its own coverage, reimbursement, or service-delivery priorities, but federal approval may be required before the state can receive federal matching funds or depart from otherwise applicable Medicaid rules.

This interaction is particularly important in areas such as:

• Eligibility and redeterminations

• Provider reimbursement and access to care

• Managed-care contracting and oversight

• Behavioral-health and substance-use services

• Home- and community-based services

• Long-term services and supports

• Prescription-drug coverage

• Section 1115 demonstration initiatives

• Coverage for people eligible for both Medicare and Medicaid

Coordinating Coverage for Dual-Eligible Individuals

People who qualify for both Medicare and Medicaid are commonly described as “dual eligible.” Medicare generally provides primary coverage for Medicare-covered services, while Medicaid may assist with premiums and cost sharing and may cover services—particularly long-term services and supports—not fully covered by Medicare.

Because the programs have different rules, funding streams, provider arrangements, and appeals systems, coordinating their benefits can be difficult. Illinois’s transition from the Medicare-Medicaid Alignment Initiative to Fully Integrated Dual Eligible Special Needs Plans is intended to coordinate Medicare and Medicaid benefits through a single managed-care structure for participating members.

Why the Distinction Matters for Policy and Advocacy

Organizations affected by Medicare and Medicaid policy often must monitor several decision-making processes at the same time:

• Federal legislation and CMS regulations

• Federal implementation guidance and funding decisions

• Illinois legislation and appropriations

• HFS administrative rules and program guidance

• State-plan amendments and waiver requests

• Managed-care contracts and provider requirements

Identifying the responsible decision-maker—and whether a proposal is a federal mandate, an Illinois policy choice, or an operational decision within existing authority—is an essential first step in developing an effective policy or advocacy strategy.

Illinois Medicaid and HR1: Common Questions Answered

This focused episode reviews HFS’s answers to common questions about the federal HR1 Medicaid changes, including community-engagement requirements, exemptions, redeterminations, reporting processes, retroactive coverage, and preparations for the January 2027 implementation period.

Understanding Medicaid Changes for Noncitizens

This episode examines the October 1, 2026 changes to federally funded Medicaid eligibility for certain noncitizens, the populations and Illinois programs that may remain eligible under separate authorities, and the importance of reviewing state notices and current HFS guidance.

Podcast analysis reflects the information and agency guidance available on each episode’s publication date. Because implementation policies may change, consult current HFS materials for updated requirements and individual eligibility questions.

Federal H.R. 1 substantially changes Medicaid eligibility and administration. Illinois is implementing the requirements in phases through the Department of Healthcare and Family Services, with different effective dates for different populations and policies.

These changes do not apply uniformly to everyone enrolled in Medicaid. Coverage category, age, household composition, Medicare eligibility, immigration status, qualifying activities, and available exemptions can determine whether and how a person is affected.

Key Implementation Dates

October 1, 2026: Federal Medicaid eligibility narrows for certain noncitizens. HFS is sending notices to affected members and has published multilingual materials explaining which federally funded and state-funded coverage pathways remain available.

January 1, 2027: New federal requirements begin for the Affordable Care Act Adult Medicaid eligibility group. These changes include community-engagement requirements and six-month eligibility redeterminations.

January 1, 2027: Illinois Medicaid retroactive coverage decreases from three months to two months before the application month for all Illinois Medicaid eligibility groups.

For current ACA Adult members, the community-engagement requirement generally applies at the member’s first redetermination occurring on or after January 1, 2027. New applicants entering the ACA Adult category after the end of 2026 will be evaluated under the new requirements.

Who Is an ACA Adult?

HFS generally describes an ACA Adult as a Medicaid member who:

• Is between 19 and 64 years old;

• Does not have a related dependent child under age 18 living in the home;

• Is not enrolled in or entitled to Medicare Part A or Part B; and

• Is not eligible through another Medicaid category.

Children, adults age 65 or older, most parents and caretaker relatives, and people enrolled through categories such as Moms & Babies, Family Health Plans, or Aid to the Aged, Blind or Disabled are not subject to the ACA Adult community-engagement requirement.

Members can review their state notices or the Benefit Details section of ABE Manage My Case to determine whether their medical coverage category is identified as “ACA.”

Community-Engagement Requirements

Affected ACA Adults must demonstrate that they completed a qualifying activity or met an exemption during the applicable review period.

Under current HFS guidance, qualifying pathways include:

• Earning at least $580 in monthly income;

• Attending school, college, a GED program, or technical training at least half-time; or

• Completing at least 80 hours in a month through work, school, volunteering, an approved work program, or a permitted combination of activities.

HFS has stated that qualifying activity during at least one month of the six-month eligibility period may satisfy the review. The state intends to use information already available through government data sources whenever possible, but members may be asked to provide additional information during an application or redetermination.

Exemptions

Federal law and HFS guidance provide exemptions for many circumstances. Examples include:

• Pregnancy and the postpartum period;

• Certain caregiving responsibilities;

• Medical frailty, disability, or other qualifying medical needs;

• Former foster youth under age 26;

• Certain American Indian or Alaska Native individuals;

• Veterans with a total disability rating;

• Participation in qualifying drug or alcohol treatment;

• Current or recent incarceration;

• Compliance with certain TANF or SNAP work requirements; and

• Certain short-term hardships.

The precise facts and documentation requirements matter. An exemption from another program does not necessarily create an automatic Medicaid exemption unless the underlying circumstances also satisfy Medicaid requirements.

HFS has indicated that it will accept self-attestation for many exemptions during 2027 when available data cannot verify the exemption, although conflicting information may result in a request for additional documentation. Guidance concerning medical frailty, provider-supported attestations, and future verification processes remains under development.

Six-Month Redeterminations

ACA Adults will transition from annual to six-month Medicaid redeterminations after their first renewal in 2027. HFS will continue attempting to verify eligibility electronically through the ex parte, or Form A, process. When eligibility or compliance cannot be confirmed through available information, the member may receive a Form B or another request for information.

Members must still complete the renewal process even when they believe they meet an exemption. If HFS cannot confirm compliance or an exemption, current guidance provides an opportunity to submit additional information before coverage ends. Adverse eligibility decisions may also carry appeal rights described in the member’s notice.

More frequent reviews may increase the risk of eligible individuals losing coverage for procedural reasons, particularly when contact information is outdated or notices go unanswered. Providers, application assisters, advocates, and community organizations may therefore have an important role in helping members understand notices and respond on time.

Reduced Retroactive Coverage

Retroactive Medicaid coverage can pay eligible medical expenses incurred before an application is submitted. Effective January 1, 2027, Illinois will reduce the maximum retroactive period from three months to two months for all Medicaid eligibility groups.

This change makes timely applications more important and may increase uncompensated-care exposure for hospitals, physicians, behavioral-health providers, long-term-care facilities, and other organizations when eligible patients apply after receiving services.

Noncitizen Eligibility Changes

Beginning October 1, 2026, federal law narrows the immigration categories eligible for federally funded Medicaid. Some humanitarian immigration categories that previously qualified under federal rules will no longer qualify unless the individual also meets another recognized category.

Separate rules continue to apply to groups that may include qualifying lawful permanent residents, certain Cuban and Haitian entrants, Compact of Free Association migrants, lawfully residing children, and lawfully residing pregnant individuals. Illinois also maintains certain state-funded or specially authorized medical programs that must be evaluated separately.

Because immigration categories and healthcare programs are legally distinct, individual eligibility should be confirmed through current HFS guidance and, when appropriate, qualified legal assistance.

Implementation Issues to Monitor

Important operational questions remain subject to additional federal and state guidance, including:

• Final medical-frailty standards and provider documentation;

• Data matching for work, income, education, and exemptions;

• ABE and Manage My Case reporting functions;

• Notices, forms, translated materials, and assistance procedures;

• Coverage reinstatement and appeal processes;

• Coordination with SNAP and TANF requirements; and

• Effects on providers, managed-care organizations, application assisters, and uncompensated care.

Organizations should rely on current written HFS and CMS guidance for implementation decisions. Earlier presentations, webinars, and toolkits remain helpful for context, but they may be superseded as agencies finalize systems and procedures.

Medicaid policy extends beyond eligibility. Illinois must finance the program, define covered services, establish payment methodologies, oversee managed-care organizations, maintain enrollment and claims systems, and ensure that participating providers can deliver care throughout the state.

Changes in any one part of this system can affect state finances, provider participation, healthcare access, and the continuity of services available to Medicaid members.

Federal and State Medicaid Financing

Medicaid is jointly financed by the federal government and Illinois. The federal government reimburses a share of qualifying state Medicaid expenditures, with the applicable federal contribution depending on the population, service, program authority, and federal matching formula.

Illinois must provide the nonfederal share needed to draw federal Medicaid funds. State appropriations, provider assessments, intergovernmental arrangements, and other authorized financing mechanisms can therefore influence the total resources available to the program.

Federal policy can significantly affect this balance. Changes to federal matching funds, provider-tax rules, state-directed payments, waiver budget neutrality, or eligible populations can require Illinois to increase state spending, reduce or redesign services, revise payment arrangements, or accept the loss of federal revenue.

HealthChoice Illinois and Managed Care

HealthChoice Illinois is the state’s primary Medicaid managed-care program. Most participating members receive covered services through managed-care organizations operating under contracts with the Department of Healthcare and Family Services.

Managed-care organizations generally receive a monthly payment for each enrolled member and assume responsibility for arranging covered care. HFS remains responsible for contract oversight and compliance with state and federal requirements.

Important managed-care policy issues include:

• Provider-network adequacy;

• Access to primary, specialty, behavioral-health, dental, and pharmacy services;

• Timely claims payment;

• Prior authorization and utilization-management practices;

• Care coordination;

• Quality measurement and health outcomes;

• Encounter-data accuracy;

• Member grievances and appeals;

• Medical-loss-ratio requirements; and

• Transparency concerning public spending and plan performance.

Managed care does not eliminate the state’s responsibility for access and quality. HFS must monitor whether contracted plans maintain adequate networks, process claims appropriately, coordinate services, and comply with beneficiary protections.

Provider Reimbursement and Access to Care

Illinois establishes Medicaid payment methodologies within applicable federal requirements. Reimbursement policy affects whether physicians, hospitals, pharmacies, behavioral-health professionals, therapists, dentists, nursing facilities, home-care providers, and other organizations can sustainably serve Medicaid members.

Provider-access concerns can arise when payment rates do not reflect workforce, compliance, technology, transportation, or service-delivery costs. Even when a service is formally covered, insufficient provider participation or geographic shortages may make that service difficult to obtain.

Payment policy can also vary by delivery system. Providers may receive reimbursement directly through the state’s fee-for-service program, through managed-care contracts, or through supplemental and state-directed payment arrangements. Each method carries different administrative, reporting, contracting, and oversight considerations.

Hospitals, Safety-Net Providers and Uncompensated Care

Hospitals and other safety-net providers play a central role in serving Medicaid members and uninsured patients. Illinois uses several payment and financing mechanisms to support hospital services, but their distribution and design remain recurring subjects of budget and legislative debate.

Eligibility restrictions, more frequent redeterminations, and reduced retroactive coverage may increase the risk that providers deliver services during a gap in coverage. These policies can produce uncompensated-care costs even when the patient could otherwise qualify for assistance.

Rural hospitals, community health centers, behavioral-health providers, pharmacies, and organizations serving populations with complex needs may face particular financial and administrative pressures when coverage rules or federal funding change.

State Plans, Waivers and Delivery-System Initiatives

Illinois’s Medicaid state plan describes the populations, services, reimbursement methods, and administrative structures approved for federal Medicaid funding. Many program changes require a state-plan amendment reviewed by the Centers for Medicare & Medicaid Services.

Federal waivers provide additional flexibility. Depending on the authority used, waivers may allow Illinois to test delivery reforms, provide home- and community-based services, coordinate care for particular populations, or operate programs differently from otherwise applicable federal Medicaid requirements.

Section 1115 demonstrations can support broader program innovations, but they are subject to federal approval, fiscal requirements, monitoring, and evaluation. Changes in federal waiver policy—including the treatment of budget neutrality—can affect Illinois’s ability to begin, expand, or continue demonstration initiatives.

Program Integrity, Data and Accountability

Because Medicaid combines substantial public funding with complex eligibility, managed-care, provider, and claims systems, oversight is an important part of program administration.

HFS, its Office of Inspector General, federal agencies, auditors, managed-care organizations, and other oversight entities may examine:

• Eligibility and enrollment accuracy;

• Provider qualifications and billing;

• Claims and encounter data;

• Managed-care payments and performance;

• Fraud, waste, abuse, and overpayments;

• Reimbursement methodologies;

• Quality and access measures; and

• Compliance with state and federal requirements.

Effective oversight must protect public resources while avoiding administrative practices that unnecessarily delay legitimate payments, discourage provider participation, or interrupt eligible members’ coverage.

Policy Questions to Monitor

Illinois Medicaid stakeholders should continue monitoring:

• The state budget and Medicaid appropriations;

• Federal matching funds and financing restrictions;

• Provider reimbursement and workforce capacity;

• Managed-care procurement, contracting, and performance;

• Hospital and safety-net financing;

• Pharmacy coverage and prescription-drug policy;

• Behavioral-health and long-term-care integration;

• State-plan amendments and waiver approvals;

• Administrative costs associated with HR1 implementation;

• Coverage losses and uncompensated-care trends; and

• HFS program-integrity, technology, and data initiatives.

These decisions affect more than government spending. They shape whether healthcare providers participate in Medicaid, whether members can obtain timely services, and whether community organizations can respond effectively when coverage or delivery systems change.

Medicare is primarily a federal program, but federal coverage, payment, prescription-drug, and managed-care policies directly affect Illinois beneficiaries, healthcare providers, insurers, and organizations serving older adults and people with disabilities.

Unlike Medicaid, Medicare’s core eligibility and benefits are not established through the Illinois state budget. Most significant Medicare changes originate in federal legislation, regulations, annual CMS payment rules, and contracts with private Medicare Advantage and prescription-drug plans.

Medicare Coverage and Annual Policy Changes

Medicare includes several distinct forms of coverage:

• Part A covers inpatient hospital care and certain skilled-nursing, home-health, and hospice services.

• Part B covers physician, outpatient, preventive, and other medical services.

• Part C, commonly called Medicare Advantage, allows beneficiaries to receive Medicare-covered benefits through federally contracted private plans.

• Part D provides outpatient prescription-drug coverage through private plans operating under federal requirements.

Premiums, deductibles, cost-sharing limits, covered-drug formularies, Medicare Advantage offerings, and provider-payment policies can change annually. Beneficiaries should review official Medicare information and plan notices during each annual enrollment period rather than assuming that prior-year costs, networks, or benefits will continue unchanged.

Prescription-Drug Affordability

Federal Medicare prescription-drug policy is undergoing significant change. The Medicare Drug Price Negotiation Program allows CMS to negotiate prices for selected high-spending drugs that lack generic or biosimilar competition. The first negotiated prices took effect in 2026, with additional groups of drugs scheduled for later years.

Other Medicare Part D changes have included:

• An annual limit on beneficiary out-of-pocket prescription-drug spending;

• The Medicare Prescription Payment Plan, which permits participating beneficiaries to spread covered Part D out-of-pocket costs over the calendar year;

• Continued limits on covered insulin costs;

• Expanded eligibility for the full Part D Low-Income Subsidy, commonly called Extra Help; and

• Changes in how beneficiaries, plans, manufacturers, and Medicare share prescription-drug costs.

These policies can reduce costs for some beneficiaries while also affecting plan design, premiums, formularies, pharmacy administration, manufacturer obligations, and federal Medicare spending.

Medicare Advantage and Plan Oversight

Medicare Advantage plans receive federal payments to provide Medicare-covered services to enrolled beneficiaries. Plans may also offer supplemental benefits that are not included in Original Medicare.

Important policy and oversight issues include:

• Provider-network adequacy;

• Prior authorization and utilization management;

• Accuracy of provider directories;

• Marketing and enrollment practices;

• Risk adjustment and payment accuracy;

• Quality ratings;

• Supplemental-benefit administration;

• Denials, grievances, and appeals; and

• Coordination with Medicaid for dual-eligible members.

Because plan availability, provider networks, prescription-drug formularies, and supplemental benefits can change, beneficiaries should compare available options using current Medicare information rather than relying only on prior plan experience or advertising.

Help With Medicare Costs

Several programs may help qualifying beneficiaries pay Medicare-related expenses.

Medicare Savings Programs are Medicaid-administered programs that may assist with Medicare premiums and, depending on the category, deductibles and other cost sharing. Eligibility is determined under applicable income, resource, and program rules.

Extra Help is a federal program that assists qualifying beneficiaries with Medicare Part D premiums and prescription-drug costs. Some people qualify automatically through Medicaid, a Medicare Savings Program, or Supplemental Security Income, while others may apply through the Social Security Administration.

Because program thresholds and individual circumstances can change, beneficiaries should use current official sources or qualified counseling when evaluating potential assistance.

Illinois Beneficiary Assistance

The Illinois Senior Health Insurance Program provides free, unbiased counseling to Medicare beneficiaries and their caregivers. Trained SHIP counselors can help individuals understand:

• Original Medicare and Medicare Advantage;

• Medicare supplement insurance;

• Part D prescription-drug coverage;

• Medicare Savings Programs and Extra Help;

• Enrollment periods and coverage options;

• Claims, denials, and appeals; and

• Suspected Medicare fraud or abuse.

SHIP does not sell insurance and can provide an independent alternative to plan marketing. Illinois beneficiaries may also obtain assistance through Medicare, the Social Security Administration, and other authorized state or community resources.

Policy Questions to Monitor

Medicare stakeholders should continue monitoring:

• Annual premiums, deductibles, and cost-sharing changes;

• Medicare Advantage payment and oversight rules;

• Prior-authorization requirements and beneficiary protections;

• Prescription-drug negotiation and Part D implementation;

• Provider reimbursement and participation;

• Rural and safety-net provider stability;

• Telehealth and home-health policy;

• Coverage of behavioral-health and preventive services;

• Access to Medicare Savings Programs and Extra Help; and

• Coordination of Medicare and Medicaid for dual-eligible individuals.

These developments can affect not only individual beneficiaries but also providers, insurers, pharmacies, aging organizations, caregivers, employers, and community groups assisting people with complex coverage needs.

Some Illinois residents qualify for both Medicare and Medicaid. These individuals are commonly described as “dual eligible” because their healthcare coverage depends on two programs with different benefits, payment responsibilities, provider arrangements, and administrative rules.

Medicare generally serves as the primary payer for Medicare-covered medical services. Medicaid may assist with Medicare premiums and cost sharing and cover services that Medicare does not fully cover, including certain long-term services and supports.

Coordinating the two programs is therefore an important state and federal policy responsibility.

Illinois’s Transition From MMAI to FIDE SNPs

Illinois previously coordinated coverage for many dual-eligible members through the Medicare-Medicaid Alignment Initiative. MMAI began serving members in portions of Illinois in 2014 as part of a federal-state demonstration intended to integrate Medicare and Medicaid benefits.

The MMAI demonstration ended December 31, 2025. Beginning January 1, 2026, Illinois transitioned to Fully Integrated Dual Eligible Special Needs Plans, commonly called FIDE SNPs.

A FIDE SNP is a type of Medicare Advantage Dual Eligible Special Needs Plan that provides Medicare and Medicaid benefits through a single managed-care organization. Illinois uses the FIDE SNP model because it most closely preserves the integrated benefits and care coordination previously available through MMAI.

FIDE SNPs are available statewide and are the only Dual Eligible Special Needs Plan model offered in Illinois. Participating plans must maintain both a Medicare contract with the Centers for Medicare & Medicaid Services and a Medicaid contract with the Illinois Department of Healthcare and Family Services.

Who May Qualify?

Under current Illinois requirements, FIDE SNP eligibility generally includes individuals who:

• Receive full Illinois Medicaid benefits through a qualifying coverage category;

• Are age 21 or older;

• Have Medicare Part A and Part B;

• Live within the selected plan’s service area; and

• Meet applicable citizenship or lawful-presence requirements.

Certain Medicaid populations are not eligible for FIDE SNP enrollment. These include some individuals receiving partial Medicaid benefits, participating in Medicaid spend-down, receiving specified developmental-disability services, or enrolled through other excluded coverage categories.

Eligibility for Medicare and Medicaid does not necessarily establish eligibility for a FIDE SNP. Individuals should confirm their Medicaid category and other requirements through HFS, Medicare, or an authorized counselor.

Coordinating Medicare and Medicaid Benefits

FIDE SNPs are designed to coordinate services that would otherwise be administered separately.

Integrated features can include:

• One managed-care organization responsible for Medicare and Medicaid benefits;

• A single member identification card;

• Coordinated physical, behavioral-health, pharmacy, and long-term-care services;

• A care coordinator familiar with both programs;

• A unified health-risk assessment and model of care;

• Combined member materials;

• Integrated grievances and appeals;

• Continuity-of-care protections; and

• Supplemental benefits designed for dual-eligible members.

The objective is to reduce fragmentation and make it easier for members, caregivers, and providers to determine which program is responsible for a service.

Integration does not eliminate all distinctions between Medicare and Medicaid. Federal Medicare requirements, state Medicaid requirements, plan contracts, provider networks, prescription-drug rules, and long-term-care arrangements may still operate differently.

Plan Choice and Enrollment

Many former MMAI members whose insurers offered successor FIDE SNPs were automatically transitioned into the affiliated FIDE SNP on January 1, 2026. Other affected members received information about selecting a FIDE SNP, Original Medicare, or another available Medicare coverage arrangement.

Eligible individuals are not required to remain in a FIDE SNP solely because they receive both Medicare and Medicaid. Depending on their circumstances, they may choose Original Medicare with prescription-drug coverage or another available Medicare Advantage option.

However, selecting a nonintegrated arrangement can mean that Medicare and Medicaid benefits are administered separately. Members receiving long-term services and supports may also be subject to distinct HealthChoice Illinois Managed Long-Term Services and Supports requirements.

Dual-eligible beneficiaries have access to special enrollment periods that may allow certain coverage changes during the year. Because changing Medicare coverage can also affect provider networks, prescriptions, care coordination, and Medicaid service delivery, members should obtain current information before changing plans.

Provider and Network Considerations

Providers serving FIDE SNP members must understand whether they participate in the member’s plan network and how the plan coordinates Medicare and Medicaid claims.

Implementation issues can include:

• Provider contracting and network participation;

• Prior authorization;

• Continuity of existing treatment;

• Coordination of primary, behavioral, pharmacy, and long-term-care services;

• Claims involving both Medicare and Medicaid responsibilities;

• Communication among plans, providers, members, and caregivers; and

• Grievance and appeal procedures.

HFS identifies a continuity-of-care period of at least 90 days for FIDE SNP members. Long-term success will depend on whether plans preserve access to established providers, coordinate services effectively, and resolve payment or authorization problems without interrupting care.

Oversight and Policy Questions

FIDE SNPs operate under both federal and state oversight. CMS regulates their Medicare responsibilities, while HFS contracts with and oversees the plans’ Medicaid responsibilities.

Important implementation questions include:

• Whether integrated care improves access and member experience;

• Whether provider networks are adequate throughout Illinois;

• How effectively plans coordinate behavioral health and long-term services and supports;

• Whether members understand their coverage choices;

• How promptly plans resolve claims, authorizations, grievances, and appeals;

• Whether supplemental benefits address members’ actual needs;

• How member advisory committees influence plan operations; and

• Whether state and federal data demonstrate improved quality and continuity of care.

The January 2026 transition was not merely a change in program name. It created a new long-term structure for coordinating Medicare and Medicaid benefits in Illinois and warrants continued evaluation by beneficiaries, providers, advocates, plans, HFS, CMS, and policymakers.
