Fully Insured Status — the highest covered status under the Social Security benefits under the Old Age, Survivors, Disability, and Health Insurance (OASDHI) Act, entitling the worker to all types of benefits, including retirement. Before a worker can collect Social Security benefits under the OASDHI Act, he or she must have credit for a certain amount of covered work. Fully insured status is typically reached after 10 years of employment in a covered occupation.
