What Types of Medicare Advantage Plans Are Available in Illinois?

There are several different Medicare Advantage plans to choose from.

  • HMO: Health maintenance organization, which limits members to a contracted provider network. Typically you need to choose a primary care provider (PCP) and must get a referral to see a specialist.
  • PPO: Preferred provider organization, which offers a wider network than an HMO but at an increased cost. You don’t need to select a PCP and don’t need a referral to see a specialist.
  • SNP: Special needs plans, for those who need more specialized care. These come in three types:
    • Chronic condition (C-SNP):1 For those who have ongoing medical issues such as diabetes or cancer. 
    • Dual eligible (D-SNP):2 For those who are eligible for both Medicare and Medicaid.
    • Institutional (I-SNP):3 For those who need care in a nursing home or other long-term facility.
  • PFFS: Private fee-for-service.4 Services are offered by a contracted provider group at preset rates. You won’t need to choose a PCP.
  • MSA: Medicare medical savings account, which is a hybrid of a medical savings account and a high-deductible plan.5

Save Money

You can save money with most Medicare Advantage plans by going to in-network providers.

What Are Prescription Drug Options with Medicare Advantage?

For MA plans in Illinois, there are two options for prescription drug coverage: a separate plan or as part of the MA plan. 

If there are specific medications you need, check your plan’s formulary, or list of covered medications, to make sure yours are included. 

Under an MA-PD plan, most Medicare Advantage HMO and PPO plans in Illinois provide prescription drug coverage. 

How Do You Choose Medicare Advantage Plans in Illinois?

Consider the costs of the plan as well as the type of coverage you want.

Your premium is the amount you pay for the plan each month. There are zero-premium plans available, though you’d still pay the Medicare Part B premium ($148.50 in 2021). However, your other out-of-pocket costs may be higher with a zero-premium plan. 

Other costs include:

  • Coinsurance, the percentage you pay for services (usually 20%) after meeting your deductible. 
  • Copays, a standard fee you pay for most services.
  • Deductibles, the yearly amount you pay before your coverage begins.
  • Maximum out-of-pocket, which in 2021 is $7,550 for in-network services.6

 Plan benefits include:

  • Vision, including eye exams and glasses or contact fittings.
  • Dental, including exams and cleanings. 
  • Telehealth, including medical office visits and psychotherapy.
  • Other perks, including access to fitness programs and hearing aids.

Additional Benefits

Most MA plans also offer vision and dental coverage.

 When Can You Enroll in Medicare Advantage?

The Medicare Annual Election Period, or Open Enrollment Period, runs October 15 through December 7.
