I'm about 10 months shy of 65 but I don't have enough quarters to qualify for Medicare or Social Security (only have 28). My wife, who is 65+, has enough quarters (40) for, and is enrolled in, parts A and B. But she's 3 quarters short of Social Security - maybe an odd situation. Anyway, I'm finding conflicting/unclear information as to how I can qualify for Medicare on her account. Does the fact that she's eligible for (and enrolled in) Medicare qualify me (at age 65) as her spouse or does she have to be eligible for Social Security as well?
