The Disability Determination Service (DDS) is a State Agency (usually) that is contracted by Social Security to make disability decisions. A certain percentage of their decisions has to, by law, be reviewed to see if their procedures are correct. These reviews are done by DQB. Most of the time, DQB finishes its review and forwards the file directly to the local Social Security office and the decision made by DDS stands. Once in a while, if there is a deficiency, the file gets sent back to DDS for additional work. Sometimes it gets re-sent to DQB. In your case, it seems the file was sent back to your local office. There's no way to tell for sure what the final decision is - but if was going to be denied in the first place, it probably wouldn't have gone to DQB - they almost always review allowances.
