A $0 plan premium is not a free plan. You still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. Star ratings are published by CMS per contract, so every plan a carrier files under the same contract shares one rating — it describes the carrier’s performance, not this specific plan’s benefits. Estimate your real 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.

Illinois HMO plans rank 34th of 49 on star rating.

Across the 76 rated plans here the average overall rating is 3.65 stars, 34th highest of the 49 states with HMO plans. Ratings apply to the contract, so every plan a carrier files under one contract shares the same score.

Common questions

Illinois Medicare Advantage HMO plans, answered

How much do Medicare Advantage HMO plans cost in Illinois?
Of the Illinois HMO plans with a published premium, 96% charge $0 a month. A $0 premium does not mean the plan is free: you still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. The number that actually caps a bad year is the in-network out-of-pocket maximum, which averages $5,965 across these plans.
What are the star ratings for Illinois HMO plans?
The 76 rated HMO plans in Illinois average 3.65 out of 5 stars, with 37 rating 4 or better and 1 rating a full 5. CMS rates a contract rather than an individual plan, so every plan a carrier files under the same contract shares one score. A contract that is too new or has too little data is not rated at all, which is different from rating badly.
How many Medicare Advantage HMO plans are available in Illinois?
There are 93 HMO plans from 16 carriers, sold across 102 counties. Availability is set by county, so the plans you can actually join depend on where you live — the full list is rarely available in any one place. 25 of them are Special Needs Plans with extra eligibility rules (see below).
Do Illinois HMO plans include prescription drug coverage?
93 of the 93 HMO plans here bundle Part D drug coverage into the plan. That is the usual arrangement for Medicare Advantage and there is no separate drug premium for it — the plan premium covers both. If you join a Medicare Advantage plan without drug coverage, you generally cannot add a standalone Part D plan alongside it.
What is a Special Needs Plan, and are there any in Illinois?
25 of the 93 HMO plans in Illinois are Special Needs Plans. SNPs limit enrollment to people who also have Medicaid, live in a nursing home or similar institution, or have a qualifying chronic condition. They often carry richer benefits for that group, but if you do not meet the criteria you cannot join one — so the real number of plans open to you may be lower than the total.

A $0 premium is not the whole cost.
