Why C is correct
The initial Medicare supplement open enrollment period lasts 6 months and begins with the month in which the person is both at least 65 years old and enrolled in Medicare Part B. This right, applied in Illinois under the 215 ILCS 5/363a framework and explained in the Illinois SHIP guide, guarantees access to a Medicare supplement policy without underwriting during that window.
Why the other options are wrong
- A) 45 days is the annual birthday open enrollment window between ages 65 and 75, not the initial open enrollment period.
- B) 90 days is not the Medicare supplement initial open enrollment period; the correct trigger is the month the person is both 65 or older and enrolled in Medicare Part B.
- D) Retirement is not the trigger for the initial open enrollment period; Medicare Part B enrollment and reaching age 65 are.
