If you are at least age 62 and have worked for at least 10 years in Medicare-covered employment, your spouse can get Medicare Parts A and B at age 65. If you have worked at least 10 years in Medicare-covered employment but are not yet age 62 when your spouse turns age 65, he or she will not be eligible for premium-free Medicare Part A until your 62nd birthday. In this case, your spouse should still apply for Medicare Part B at age 65 so that he/she can avoid paying a higher Part B premium. However, if you are still working and your spouse is covered under your group health plan, he/she could delay enrollment in Part B without paying higher premiums. See: Can I delay my Medicare Part B enrollment without paying higher premiums? for more information on this. See also: How do I enroll in Medicare?
