To qualify for Social Security disability benefits, you must first have worked in jobs covered by Social Security. Then you must have a medical condition that meets Social Security’s definition of disability. In general, we pay monthly cash benefits to people who are unable to work for a year or more because of a disability.
Benefits usually continue until you are able to work again on a regular basis. There are also a number of special rules, called “work incentives,” that provide continued benefits and health care coverage to help you make the transition back to work.
If you are receiving Social Security disability benefits when you reach full retirement age, your disability benefits automatically convert to retirement benefits, but the amount remains the same.
