2026

2026 Plan Changes and Improvements
The finalized 5.06% Medicare Advantage payment rate increase represents one of the most substantial funding improvements in recent years, directly impacting the scope and quality of benefits offered to Illinois residents.

New provider network arrangements and facility partnerships
Available Plan Types in Illinois
Health Maintenance Organization (HMO) Plans
HMO plans emphasize care coordination through a network of contracted providers, typically offered in more densely populated areas like Cook County and surrounding collar counties. Members must select a primary care physician who coordinates their care and provides referrals to specialists within the network.
These plans usually feature lower premiums and out-of-pocket costs compared to other plan types, making them attractive options for budget-conscious beneficiaries. However, members have limited flexibility to receive covered services outside the plan’s network.
Preferred Provider Organization (PPO) Plans
PPO plans offer broader network flexibility, allowing members to visit both in-network and out-of-network providers. While in-network services receive maximum coverage, members can still receive benefits when visiting out-of-network providers, typically at higher cost-sharing levels.
These plans best suit Illinois residents who want provider choice flexibility and are willing to pay somewhat higher premiums for the privilege. PPO plans are particularly valuable for members in rural areas where provider options may be limited.
Dual Special Needs Plans (D-SNP)
D-SNP plans are tailored for beneficiaries eligible for both Medicare and Medicaid, often featuring integrated care coordination and expanded supplemental benefits. These plans may include unique services like transportation assistance, meal delivery programs, and enhanced care management support.
UnitedHealthcare’s D-SNP reach continues expanding in Illinois markets, offering comprehensive support services specifically designed for lower-income individuals who qualify for both programs.
Chronic Special Needs Plans (C-SNP)
C-SNP plans are designed for people with specific, severe, or disabling chronic conditions such as diabetes, heart failure, or chronic kidney disease. These specialized plans offer targeted benefits and provider networks experienced in treating specific diseases.
Members receive access to disease management resources, specialized care teams, and enhanced benefits tailored to their specific chronic conditions, helping improve health outcomes and quality of life.
Key Benefits and Coverage Features
UnitedHealthcare medicare advantage plans in Illinois integrate prescription drug coverage with medical benefits, providing members with comprehensive healthcare solutions. This integration eliminates the need for separate Part D plans and simplifies medication management.
Core Medical Benefits
All plans include standard Medicare Part A and Part B benefits, often with enhanced coverage levels. Many plans feature $0 or low monthly premiums, making them attractive alternatives to Original Medicare plus a supplement plan.
Prescription drug coverage follows Medicare’s standardized formulary structure while often providing additional benefits like preferred pharmacy networks and mail-order options that can reduce medication costs.
Supplemental Benefits Coverage
Dental, vision, and hearing aid benefits come with specific network requirements and annual maximums. These benefits significantly enhance the value proposition compared to Original Medicare alone.
Vision benefits typically cover routine eye exams and provide allowances for eyewear ranging from $100 to $300 annually. Members can visit network eye care providers and receive covered services with minimal out-of-pocket costs.
Hearing aid coverage often provides substantial allowances ranging from $500 to $2,000 per device every 2-3 years, depending on the specific plan selected. Coverage may be limited to specific brands or network audiologists.
Additional Member Perks
Over-the-counter (OTC) allowances enable members to purchase eligible health-related items quarterly, with benefit values typically ranging from $25 to $150 depending on plan selection. Members can order approved products conveniently through network vendors.
Fitness and wellness programs often include partnerships with national gym networks or virtual wellness platforms, encouraging active lifestyles and preventive care.
Food and nutrition benefits may include healthy food allowances or meal delivery services for qualifying members, particularly those managing chronic conditions or recovering from hospitalizations.
Transportation services provide eligible members with rides to and from medical appointments, addressing a critical barrier to care access, especially for vulnerable or rural populations.
Supplemental Benefits Details
Dental coverage typically includes three tiers of services: preventive care (cleanings, exams), basic services (fillings, extractions), and major services (crowns, dentures). Annual maximums generally range from $750 to $2,000, with higher limits available on premium plans.
Preventive dental services often receive 100% coverage within network, while basic and major services may require member cost-sharing. Some plans offer waiting periods for major services, so reviewing specific plan documents is essential.
Vision benefits cover routine eye exams with network providers and provide annual allowances for glasses or contact lenses. Members typically receive one covered eye exam per year plus their eyewear allowance.
OTC benefits are delivered through approved vendors, with members receiving quarterly allowances to purchase eligible health and wellness products. Unused amounts typically expire at the end of each benefit period, encouraging regular utilization.
Fitness benefits may include gym memberships, fitness classes, or home exercise equipment allowances. Some plans partner with popular fitness chains to provide members with access to thousands of locations nationwide.

How to Compare and Choose Plans
Using Medicare.gov Plan Finder
The Medicare.gov Plan Finder tool provides comprehensive, zip-code-specific plan comparisons for UnitedHealthcare options in your Illinois county. This official tool offers real-time information about premiums, benefits, provider networks, and prescription drug coverage.
Enter your medications to see exact coverage details and costs under different plans. The tool calculates estimated annual costs based on your specific prescription needs and healthcare utilization patterns.
Evaluating Provider Networks
Review provider networks carefully to ensure your preferred doctors, hospitals, and specialists participate in the plan you’re considering. Network participation can change annually, so verify current provider status even if they participated in previous years.
Contact providers directly to confirm their participation status and any restrictions on new Medicare Advantage patients. Some providers may have limited availability for new MA members.
Prescription Drug Considerations
Compare prescription drug formularies for your specific medications, paying attention to tier placement and any coverage restrictions. Some medications may require prior authorization or step therapy protocols.
Review pharmacy networks to ensure convenient access to your medications. Many plans offer mail-order options that can provide cost savings and convenience for maintenance medications.
Total Cost Analysis
Evaluate total annual costs including premiums, deductibles, copayments, and out-of-pocket maximums. The lowest premium plan may not provide the best value when considering your expected healthcare utilization.
Consider both best-case and worst-case scenarios when evaluating out-of-pocket maximum limits. Plans with higher premiums sometimes offer better protection against catastrophic medical expenses.
