When you qualify for Illinois Medicaid, obtaining coverage is only the initial milestone. Most beneficiaries are required to select a specific Managed Care Organization (MCO) under the state’s HealthChoice Illinois program. Navigating to enroll.hfs.illinois.gov/compare-plans puts you directly in driver’s seat, letting you contrast plans before locking in coverage for the year.

Choosing the wrong health plan can mean having to change a primary care physician, losing access to an established medical center, or paying out-of-pocket for non-covered over-the-counter essentials. This structured breakdown explains how the HFS comparison portal works, how major plans differ, and how to execute your choice cleanly.
1. Key Health Plans Available on the Illinois HFS Portal
While all HealthChoice Illinois plans cover the state’s mandatory baseline benefits (doctor visits, hospitalization, maternity care, behavioral health, and prescription drugs), they differ in network breadth, regional availability, and extra “value-added” incentives:
| Managed Care Plan (MCO) | Service Footprint | Primary Strengths | Common Value-Added Perks |
|---|---|---|---|
| Blue Cross Community Health Plans | Statewide (All 102 Counties) | Extensive provider network; high hospital participation | Wellness rewards, over-the-counter allowances, gym membership programs |
| Meridian Health Plan of Illinois | Statewide (All 102 Counties) | Largest enrollment share; strong pharmacy coordination | Comprehensive dental credits, prenatal reward incentives, health food cards |
| Aetna Better Health of Illinois | Statewide (All 102 Counties) | CVS integration; strong care-coordination support | CVS health brand allowances, transportation aid, post-discharge home meals |
| Molina Healthcare of Illinois | Select Central, Southern & Northern Counties | Community-based clinic relationships; chronic condition focus | Vision enhancements, maternal baby showers, educational scholarships |
| CountyCare Health Plan | Cook County Only | Direct integration with Cook County Health system | Extensive local Cook County transport, robust food security initiatives |
2. How to Use the Comparison Tool Step-by-Step
The online portal at enroll.hfs.illinois.gov/compare-plans is engineered to filter out plans that do not operate in your specific geographic zone. Follow this checklist to compare accurately:
- Step 1: Enter Your County or ZIP Code. Plan offerings change strictly at county borders. Selecting your home county filters out non-participating insurers instantly.
- Step 2: Check Your Primary Care Physician (PCP). Do not assume a doctor accepts every plan carrying the “Blue Cross” or “Aetna” badge. Select “Find a Doctor” within the tool to verify that your medical provider is in-network for the specific Medicaid Community line of business.
- Step 3: Review Hospital Affiliations. If you require ongoing care or expect surgical procedures at major institutions (such as Northwestern, Rush, or UI Health in Cook County, or OSF/Carle downstate), confirm that the entire health system participates in the plan’s acute network.
- Step 4: Audit Prescription Formularies. Check whether brand-name medications, insulin varieties, or maintenance therapies are included on the plan’s preferred drug list (PDL) without prior authorization hurdles.

3. Crucial Rules: Auto-Assignment & The 90-Day Lock-In
Timing is paramount when dealing with the Department of Healthcare and Family Services (HFS):
- The Auto-Assignment Trap: When your Medicaid eligibility is approved, HFS mails an enrollment packet with a specific selection deadline (usually 30 to 60 days). If you fail to choose a plan through the portal by that date, the state automatically assigns you an MCO based on previous provider usage or family plan linkages.
- The 90-Day Switch Period: From the official effective date of your plan enrollment, you receive an automatic 90-day grace period. During these 90 days, you can switch to any other available plan in your county via the portal without needing an excuse or special permission.
- Annual Open Enrollment: Once your initial 90 days lapse, you remain locked with that insurer until your annual Open Enrollment window arrives (typically timed around your Medicaid redetermination anniversary).
4. Legitimate “For Cause” Mid-Year Transfers
If your 90-day window has closed and you experience significant issues with your assigned plan, you can request a “Change for Cause” transfer directly through HFS Client Enrollment Services under the following conditions:
- Your primary care physician or key specialist was terminated from the plan’s network, and continuity of care is disrupted.
- The plan fails to provide medically necessary services or fails to supply access to care within established state travel/distance standards.
- You moved to a new county where your current plan does not operate or offers a severely restricted provider footprint.
Always complete your plan comparison directly via the official secure domain at enroll.hfs.illinois.gov or through the official Client Enrollment Services hotline at 1-877-912-8880. Third-party lead generation websites often present outdated provider rosters or bias suggestions toward specific commercial carriers.
