Why A is correct
The Part B Special Enrollment Period for people who had group health coverage based on current employment — their own or a spouse's — lasts eight months, beginning the month after employment or the group coverage ends, whichever comes first. Enrolling during this SEP avoids the Part B late enrollment penalty. This SEP exists only while the group coverage is based on active employment, and its eight-month length is a specific exam number in the Part B enrollment objectives.
Why the other options are wrong
- B) The SEP is eight months, not two years, for employer group coverage after age 65.
- C) Three months after the birthday month is part of the Initial Enrollment Period window, not the employer-coverage SEP.
- D) The SEP for employer group coverage is eight months, not six.
Memory hook
Eight months to get your Part B without penalty after employer coverage stops — a generous second window.
