Compare 2026 Illinois Medicare Advantage options by county
Medicare Advantage plans are offered by county, so the most useful comparison starts with where you live. Use this page to narrow your options before reviewing plan details or entering your ZIP code.
As you compare plans, look at monthly premium, prescription coverage, provider network, dental, vision, hearing, maximum out-of-pocket limit, and Star Ratings together.
The plan with the lowest premium is not always the lowest-cost option after prescriptions, copays, doctors, and out-of-pocket limits are considered.

Are Medicare Advantage plans the same in every Illinois county?
No. Plan availability, networks, premiums, and benefits can change by county. Always compare using your ZIP code or county before relying on a statewide list.
What does Medicare Choose help me compare?
Medicare Choose helps organize public plan data around premiums, plan type, benefits, Star Ratings, drug coverage signals, and local availability so you can decide what deserves a closer look.
Should I pick the plan with the most extra benefits?
Not automatically. Extra benefits matter, but you should also review doctors, hospitals, prescriptions, maximum out-of-pocket limits, and how the plan works for your care routine.
Can a licensed agent help me compare Illinois plans?
Yes. A licensed Medicare agent can explain plan tradeoffs, confirm network and prescription details, and help you enroll if you choose a plan. Medicare Choose can help you find local agent options.
