How does Social Security determine if I qualify for SSDI?

Under Social Security rules and federal law, in order to qualify for SSDI, you must have a total disability that has or is expected to last for at least 12 months (or result in death) and you must have worked enough to be insured under Social Security law. Benefits are not payable for partial disabilities or for a short-term disability.

Social Security defines disability as your inability to do the work you performed before your disability began and the Social Security Administration determines that because of your disability you cannot adjust to other work. Your disability must also last or be expected to last for at least 12 months or to result in death.
