HealthSpring Medicare Advantage in Illinois for 2027: 6 Plans, County by County

SPRINGFIELD, Ill. — For the 2027 plan year, HealthSpring is offering six Medicare Advantage plans across Illinois, according to the federal Medicare Advantage Landscape Source Files released by the Centers for Medicare & Medicaid Services (CMS). HealthSpring is listed by CMS under its parent organization, Health Care Service Corporation (HCSC), and the plans go by the HealthSpring name on the Medicare Plan Finder.

This article is published by an independent Medicare education site. We are privately owned, not part of the government, and not affiliated with HealthSpring or any other insurance carrier. Our goal here is to help Illinois readers understand what is on the 2027 CMS landscape file for this one carrier — nothing more.

What HealthSpring offers in Illinois for 2027

CMS lists 6 HealthSpring Medicare Advantage plans in Illinois for 2027. By plan type, that breaks down to 2 HMO plans, 1 HMO-POS plan, and 3 PPO plans. All 6 include Part D prescription drug coverage.

HealthSpring does not list any Special Needs Plans in Illinois for 2027 — no Dual-Eligible SNP (D-SNP), no Chronic Condition SNP (C-SNP), and no Institutional SNP (I-SNP). Shoppers who specifically need an SNP will need to look at other carriers on the Illinois landscape.

For context, 12 other carriers also offer Medicare Advantage plans somewhere in Illinois for 2027, and together all carriers in the state put 139 plans on the CMS landscape file. HealthSpring is one piece of a crowded statewide picture.

HealthSpring plans with the widest county reach

The table on this page lists every HealthSpring plan in Illinois for 2027 along with the number of counties where each one is offered. In descending order of county reach, the plans are:

• HealthSpring Preferred (HMO) — offered in 5 counties
• HealthSpring Preferred Savings (HMO) — offered in 5 counties
• HealthSpring Premier (HMO-POS) — offered in 5 counties
• HealthSpring True Choice (PPO) — offered in 5 counties
• HealthSpring True Choice Savings (PPO) — offered in 5 counties
• HealthSpring True Choice (PPO) — new for 2027, offered in 2 counties

Each of these includes Part D drug coverage. Because Medicare Advantage is sold county by county, a plan on this statewide list may not be offered where you live. The only reliable way to see which plans are available at your address is to run your ZIP code and county through the Medicare Plan Finder at Medicare.gov.

What is new, and what is not returning

For 2027, HealthSpring has 1 new plan on the Illinois landscape: a HealthSpring True Choice (PPO) offered in 2 counties.

CMS data available to us does not include a count of HealthSpring plans that are not returning for 2027 in Illinois, so we are reporting none on that line rather than guessing. If you are currently enrolled in a HealthSpring plan, your carrier is required to send you an Annual Notice of Change (ANOC) by late September 2026. That letter will tell you directly whether your specific plan is continuing, changing, or ending for 2027.

Checking your county, doctors, and prescriptions

Three checks matter before you choose any Medicare Advantage plan — HealthSpring or otherwise:

1. County availability. Enter your ZIP code at Medicare.gov to see which of the HealthSpring plans listed above are actually sold in your county. 2. Providers. Confirm that your primary care doctor, specialists, and preferred hospitals are in the plan's network. Call the provider's office directly as well as the plan, since directories can lag. 3. Prescriptions. Enter each medication you take into the Plan Finder to see how a given plan's formulary treats it. The Evidence of Coverage (EOC) and the plan's formulary document posted by the carrier are the authoritative sources.

We are not listing premiums, deductibles, copays, specific benefits, networks, or star ratings in this article. Those details change by plan and by county, and the official place to view them is the Medicare Plan Finder, the plan's EOC, or by calling 1-800-MEDICARE.

What to do before December 7

The Annual Enrollment Period for 2027 Medicare Advantage coverage runs October 15 through December 7, 2026. Anything you enroll in, switch to, or drop during that window takes effect January 1, 2027.

A reasonable sequence between mid-October and early December:

• Read the ANOC from your current plan, if you have one.
• Make a short list of your doctors, hospitals, and prescriptions.
• Run that list through Medicare.gov's Plan Finder using your ZIP code.
• Compare the plans actually available in your county side by side — including HealthSpring plans and plans from the 12 other carriers on the Illinois landscape.
• Enroll by December 7, 2026.

If you miss December 7, there is a Medicare Advantage Open Enrollment Period from January 1 through March 31, 2027, with more limited options. Details are on Medicare.gov under Medicare enrollment periods.
