What does being fully insured refer to in terms of Social Security coverage?

Being fully insured in the context of Social Security coverage specifically means that a person has earned 40 quarters of coverage. This quarter of coverage can be earned through a combination of work history and income earned over a certain period. Each quarter is typically earned with a minimum amount of earnings, and accumulating 40 quarters generally requires about ten years of work.

This status grants individuals access to various Social Security benefits, including retirement benefits, disability benefits, and survivor benefits. Meeting the "fully insured" status is significant because it indicates that an individual has contributed sufficiently to the Social Security system, thereby qualifying for benefits they can rely on during retirement or in case of disability.

The other choices do not accurately describe the qualifications for being fully insured. Working 20 years (as in the first choice) does not equate to the required quarters of coverage. Similarly, being enrolled in Medicare for a specific duration or paying into Social Security for 15 years does not meet the specific requirement of having the full 40 quarters of coverage necessary to be deemed fully insured.
