How does an individual qualify as fully insured under Social Security disability coverage?

To qualify as fully insured under Social Security disability coverage, an individual must have been credited with the appropriate number of quarters of coverage. This means that the person needs to have earned a certain number of work credits, which are based on their historical employment and earnings. Specifically, an individual typically needs to have accumulated at least 40 quarters of coverage, although younger individuals may qualify with fewer quarters based on their age and work history. This system ensures that only those who have contributed to the Social Security system through their work are eligible for benefits, thus linking the benefits directly to their employment record.

The other options focus on aspects that do not determine the qualification for being fully insured. For instance, being currently employed or expecting to be disabled for a specific duration does not directly impact the individual's work history required for Social Security coverage. Additionally, coverage under Medicaid is a separate program aimed at providing medical assistance and is not a factor in determining eligibility for Social Security disability benefits.
