Answer & full 3-part explanation (select an option above, or peek)
Why A is correct
Per the Michigan Department of Insurance and Financial Services (DIFS), the Medicare supplement open enrollment period lasts 6 months and begins on the first day of the month in which the person is both at least 65 and enrolled in Medicare Part B. During that window the insurer may not use underwriting and may not impose a preexisting-condition waiting period.
Why the other options are wrong
- B) The trigger is Part B enrollment at 65 or older, not a countdown before the 65th birthday month.
- C) Open enrollment is keyed to the individual's Part B enrollment month, not the calendar year.
- D) Part A enrollment alone does not start the window; both the age and Part B enrollment conditions must be met.
Memory hook
Open enrollment starts when 65 and Part B meet: 6 months, no underwriting, no waiting.
