Social security defines disability as having a severe medically determinable impairment that has lasted or is expected to last at least one year. So a couple of things about that. Number one it has to be pretty severe. It has to be so severe it has to keep you from being able to do eight hours of work a day, five days a week, full-time employment. Next is the one-year requirement. It has to be expected to last a year or has already lasted at least one year, which means it does not include medical conditions that are expected to improve within 12 months. That excludes a lot of claims.
