Best Medicare Supplement Plans in Illinois

Medicare Supplement plans in Illinois, also called Medigap, help pay for deductibles and coinsurance that Original Medicare doesn't cover. Many people assume that the Medicare benefits from Original Medicare Part A and Medicare Part B are sufficient for reducing their out-of-pocket costs for healthcare.

There are 10 Medicare Supplement plans to choose from.

In Illinois, Medicare Supplement Plan G is the best overall plan for 2022.

Plan F and Plan N are considered by many to be the best after Plan G.

Best Plan G:

Mutual Of Omaha Medicare Supplement Plan G

For Medicare beneficiaries who enrolled in Medicare after January 1, 2020, Medicare Plan G offers the most comprehensive coverage of all Medicare Supplement plans in Illinois.

Plan G also offers cost savings for anyone eligible for Plan F too.

Best Plan N:

Mutual Of Omaha Medicare Supplement Plan N

Medigap Plan N offers:

  • Economical monthly premiums in exchange for rich benefits. It would help if you compared the benefits you get with Plan N to what other plans offer to ensure that the lower monthly premiums are worth it.
  • One hundred percent of Medicare Part B coinsurance apart from outpatient copays up to $20.00 and emergency room copays of $50.00 unless the patient is admitted.
Best High Deductible Plan G:

Mutual Of Omaha High-deductible Medicare Plan G

High-deductible Plan G requires beneficiaries to meet an annual deductible of $2,490.00 before coverage begins. As a result, premiums are lower than the standard Plan G.

When can I apply for a Medicare Supplement plan?

During the Medigap Open Enrollment Period

If you are 65 or older

For those aging into Medicare, eligibility for enrollment in a Medicare Supplement insurance plan in Illinois begins on the month you enroll in Medicare Part B (whether at 65 or older) and lasts for six months. If you receive Social Security retirement benefits at age 65, you are automatically enrolled in Medicare.

In Illinois, the Medigap Open Enrollment Period (OEP) is the optimum time to enroll in Medigap because you must be accepted even if you have pre-existing conditions.

If you are younger than 65

The Federal Medicare program doesn't require a Medicare insurance company to sell Medigap plans to those under age 65. However, those under 65 receiving Medicare because of disability can purchase Medicare Supplement insurance during the Open Enrollment Period in Illinois. They also get another six-month Open Enrollment Period when they reach Medicare eligibility at age 65.

If you get notification of eligibility retroactively, your six-month OEP begins on the day you are notified.

Outside OEP with Guaranteed Issue Rights

In Illinois, you can purchase Medicare Supplement insurance if you have guaranteed issue rights. In addition, you may have guaranteed issue rights if you have other health coverage that changes – through an employer or other circumstances.

Because of these rights, private health insurance companies are required by law to do the following:

  • Sell Medigap insurance policies to anyone eligible regardless of pre-existing conditions
  • Cover all pre-existing health conditions for eligible enrollees
  • NOT charge more for the plan because of past or present health conditions

The Annual Election Period (AEP)

The AEP goes from October 15 to December 7. During this enrollment period, Medicare beneficiaries can get Medicare coverage through Medicare Advantage or Medicare Part D plans (prescription drug plans). The AEP does not apply to Medicare Supplement plans.


When can I change Medigap plans?

If you want to switch from one Medigap plan to another, technically, you can do so at any time. However, you may be subject to medical underwriting if you change plans outside your Medigap Open Enrollment Period. Switching plans during OEP protects you from underwriting.

The effective date for your new policy is the first day of the month following the switch.

Can I be denied Medigap coverage?

If you enroll in a Medicare Supplement insurance policy during your Open Enrollment Period, or if you have guaranteed issue rights, you can enroll in any Medigap plan in Illinois without undergoing medical underwriting. This means you cannot be denied coverage during these enrollment periods, regardless of your health status. Ready to learn more?
