More than 2.3 million people in Illinois are signed up for Medicare, making it the seventh-largest state for Medicare beneficiaries.

Medicare is the government health care program for people 65 and older. Medicare Advantage is a bundled alternative to Medicare sold by private insurance companies. It offers all the same benefits and usually some extras, such as cost help with dental and vision coverage.

Medicare Advantage plans offer more benefits than Original Medicare, and they're often cheaper than paying for Medicare and a Medicare Supplement plan, but they offer less flexibility because you’ll need to get care from within the plan’s network of providers. Weigh your options to determine what plan best suits your needs.

Find the right Medicare Advantage plan

It’s important to do your research before selecting a Medicare Advantage plan for yourself. Here are some questions to consider asking:

  • What are the plan’s costs? Do you understand what the plan’s premium, deductibles, copays and/or coinsurance will be? Can you afford them?

  • Is your doctor in-network? If you have a preferred medical provider or providers, make sure they participate in the plan’s network.

  • Are your prescriptions covered? If you’re on medication, it’s crucial to understand how the plan covers it. What tier are your prescription drugs on, and are there any coverage rules that apply to them?

  • Is there dental coverage? Does the plan offer routine coverage for vision, dental and hearing needs?

  • Are there extras? Does the plan offer any extra benefits, such as fitness memberships, transportation benefits or meal delivery?
