In most states, including Illinois, you cannot count on getting Medigap later
You can buy any Medigap plan with no health questions in the 6 months that start when you are 65 or older and have Part B. After that, a Medigap company in Illinois can ask about your health. It can say no, or it can charge you more. So if you join a Medicare Advantage plan now, you may not be able to get Medigap later. Illinois’s birthday rule helps only people who already have Medigap, not people who leave Medicare Advantage.
One exception is the trial right. If you joined Medicare Advantage when you first got Medicare at 65, or you left a Medigap plan to try Medicare Advantage for the first time, you can switch back within 12 months. Then you can buy a Medigap plan with no health questions.

Sources and method
Plan data comes from the CMS 2027 Plan Benefit Package and landscape files. The data is from 2026-10-10. Original Medicare amounts are the 2027 projections in the 2026 Medicare Trustees Report (Tables V.E1 and V.E2). CMS sets the final amounts in November. We do not have a Medigap price for Williamson County, IL. So the Original Medicare total needs your own Medigap quote. You can look up prices for ZIP 62959 on Medicare.gov. Totals use typical Medicare-allowed amounts for each service and typical drug prices.
