Medicare Advantage plans in Illinois
Illinois has 172 Medicare Advantage plans from 17 carriers, averaging 3.63 out of 5 stars across the 145 plans CMS has rated. The first real decision is HMO or PPO — how far you can go outside the plan’s network, and what that freedom costs.
Illinois has 1 five-star Medicare Advantage HMO plan.
Of the 93 HMO plans here, 1 carry CMS's top overall rating of 5 stars and 37 rate 4 or above. That matters beyond quality: a 5-star plan can be joined at almost any point in the year through a special enrollment period, rather than only during the autumn window.

Other Medicare coverage
Every figure on this page covers HMO and PPO plans. A small number of PFFS and Cost plans are sold in some states and are not included above — there are too few nationally (71 across 17 states) to compare meaningfully. Standalone Part D drug plans and PACE programmes are different products entirely and are not Medicare Advantage; you can find any available on the full Illinois plan list. Illinois has 1 five-star plan, which can be joined outside the normal enrolment window.
