This is the “short-cut" step. If you have a condition which is contained in the Social Security Listing of Impairments; AND the medical findings match what is required for your listing, you may be found disabled without Social Security considering the last two steps. This is “meeting a listing." You can also be found disabled at this step if your condition “equals a listing." Equaling a listing means that while your condition may not be mentioned in the Listing of Impairments, it is just a severe AND has the same findings as a listed impairment. It is the only way to win without getting through all 5 steps.
