http://www.rabinsslaw.com/types-of-impairments - The Social Security Administration lists a large number of conditions, known as the “Listing of Impairments,” for both children and adults, that can meet its definition of disability. We work on a contingency fee basis, which means no money up front and no hourly fees. Our fees must be approved by the Social Security Administration (SSA) and comply with SSA guidelines. We file our fee agreement with the SSA in every case.
