Which Illinois Medicare plans are ending in 2027?

Checked October 6, 2026 against CMS's 2026 and 2027 plan lists and September 2026 enrollment.

The biggest plans ending: Blue Cross (19,455 members), Aetna (16,734 members), Humana (15,170 members). CMS's 2027 Plan Crosswalk says 57 Illinois Medicare Advantage and Part D plans end or leave counties for 2027, with at least 56,813 people enrolled who must choose a new plan. Another 13 plans (52,646 people) were merged into other plans or given new plan numbers; CMS moves those members automatically, and their letter names the new plan. A plan that ends stops on December 31, 2026. It does not mean you lose Medicare. Your plan's own letter is the final word.

Full detail by company and county: Illinois Medicare plan changes for 2027. CMS hides county counts of 10 or fewer, so totals are at least the number shown.

Medicare Advantage plans available in Illinois for 2027

Checked 2026-10-17 against CMS's 2027 plan benefit and county files.

139 Medicare Advantage plans are offered in Illinois for 2027 by 14 companies. 68 are HMO plans and 66 are PPO plans, with 2 private fee-for-service. 30 are special needs plans, which only people who qualify (for example, people who also have Medicaid or a chronic condition) can join, so 109 are open to most people with Medicare. Depending on the county, you can choose from between 9 and 67 plans.

Compared with 2026: 168 plans were offered in Illinois in 2026, so the count is down by 29 for 2027. Listed in CMS's 2026 files but not its 2027 files: Blue Cross and Blue Shield of IL, NM, OK, TX (7 plans in 2026), Cigna HealthCare (7 plans in 2026), Clear Spring Health (5 plans in 2026), Blue Cross and Blue Shield of Illinois (1 plan in 2026), Wellcare By Meridian (1 plan in 2026). A company can also appear to leave because it changed its name, so check your own plan's letter.

No cost. No obligation. Not the government. Speak with a licensed insurance agent (TTY 711).

Will a 2027 plan keep your doctors and cover your prescriptions?

The public plan sites can't tell you that without a lot of clicking, and some 2027 plans aren't on them until October 15. Give us your doctors and your prescriptions and a licensed agent checks every 2027 plan in your county against your list, then calls you with the two or three that fit. No cost, no obligation.

Got a letter saying your Medicare plan is leaving or won't renew?

A non-renewal letter means your specific plan won't continue in your county after December 31, 2026. It doesn't mean you lose Medicare, and it usually doesn't mean your insurance company is leaving Medicare altogether. You can choose a new Medicare Advantage plan, or move to Original Medicare with a Medigap plan and a Part D drug plan.

My Medicare Advantage plan is ending. What are my deadlines?

Your current plan keeps working through December 31, 2026. Doctors, prescriptions and benefits work as usual until then.
Open Enrollment, October 15, 2026 to December 7, 2026: pick a new plan now and it starts January 1, 2027, with no gap.
Your extra window, December 8, 2026 to February 28, 2027: because your plan is being discontinued, you get a Special Enrollment Period on top of Open Enrollment. An enrollment request received December 8-31 is effective January 1; received in January, effective February 1; received in February, effective March 1.
Medigap guaranteed issue: apply as early as November 1, 2026, and no later than March 4, 2027 (63 days after your coverage ends).

What happens if I do nothing when my plan is cancelled?

You don't lose Medicare. If you don't choose a new plan, you're moved to Original Medicare (Parts A and B) on January 1, 2027. Original Medicare doesn't include prescription drug coverage, so you'd need to join a separate Part D plan. Going 63 days or more without creditable drug coverage can mean a permanent late-enrollment penalty.

Can I switch to a Medicare Supplement (Medigap) plan without health questions?

Usually yes. When a Medicare Advantage plan leaves your area or stops offering coverage, federal law gives you a guaranteed issue right: a Medigap company must sell you Plan A, B, D or G (or C or F if you were eligible for Medicare before January 1, 2020), can't charge more for past or present health problems, and can't refuse you, as long as you switch to Original Medicare. Some states add more rights than this. Keep your non-renewal letter; it can serve as proof.

I just found out my plan is ending. Do I need to decide right away?
