Medicare Supplement Plans in Illinois

The best Medicare Supplement insurance plans in Illinois for 2022 cover Medicare-approved, out-of-pocket expenses that you are expected to pay when you are enrolled in Medicare Part A and Part B. There are 10 Medicare Supplement plans, each designated by a different letter: A, B, C, D, F, G, K, L, M, and N. Depending on the plan you choose, some or all of these expenses are covered:

•    Copayments.

•    Deductibles.

•    Coinsurance.

Unlike Original Medicare insurance that is underwritten by the federal government, Medicare Supplement plans are sold by private insurance companies. The Illinois Department of Insurance regulates these companies and stipulates which Medicare Supplement plans in Illinois are offered.

Because these plans fill in the gaps in coverage of Original Medicare, they are also known as Medigap plans. Each company must offer the same benefits for a given plan. However, companies can set their own rates for a plan, so it pays to compare.

Medicare Supplement plans can be used with any doctor or healthcare institution in the U.S. that accepts Original Medicare. There are no preferred providers or geographical restrictions.

What is the Best Medicare Supplement Plan in Illinois?

In 2022, the most popular Medicare Supplement plan in Illinois is Plan G. Enrollees like this Medicare Supplement plan for its well-rounded benefits and affordable rates, even if you have pre-existing conditions.

Plan G: Best comprehensive medical coverage

The Medigap Plan G covers the following:

– Allows you to see a U.S. doctor that accepts Original Medicare
– All of Medicare Part A coinsurance, copays, and deductibles
– Part B coinsurance and copayments

Plan G does not cover Part B deductible. With Plan G, those will be your only out-of-pocket costs. For Medicare coverage for a Prescription drug plan, you will need Medicare Part D Plan. See below:

– Medicare Part D Plan covers outpatient retail prescriptions

– Plan G does offer prescription drug coverage for all Part B medications

Other basic benefits of Plan G include:

  • The ability to change doctors anytime
  • The freedom to go to any hospital or facility for health care that takes Original Medicare
  • Covers 100% Excess Charges
  • Covers foreign travel emergency

Also, no referrals are needed with this plan, and you can go outside of the network.

Plan F: Best full coverage

Before 2021, Plan F was one of the best Medicare Supplement plans in Illinois for full coverage. It is available to those who were eligible for Medicare coverage prior to 1/1/2020.

Plan F includes Medicare Part B deductible as part of its cost, so you do not have to pay this expense. If you do not qualify for Plan F, then Plan G will be the next best Medigap policy to choose. The only difference is Plan G does not include the Medicare Part B deductible.
