If denied you would then apply for reconsideration with the state agency that handles disability on behalf of the Social Security Adminstration. That agency could approve your application, which might then be subject to Quality Control review, and possibly denied. The agency could also deny your application again. Some states skip the reconsideration stage.
If you're still denied, you would then apply for a hearing with an administrative law judge (ALJ). The ALJ could approve your application, again with the possibility of Quality Control review, or deny your application.
If the ALJ denies your application, you can then appeal to the Social Security Administration Appeals Council. If denied again, you can then appeal to United States District Court.
Your Social Security disability benefit will be reduced so that the combined amount of the Social Security benefit you and your family receive plus your workers' compensation payment and/or public disability payment doesn't exceed 80 percent of your average current earnings.
