You definitely should make sure social security gets the new MRI results ad the psych eval (if that didn't come from them). Everything new is good.

Evaluation by any doctor also can help but it would just be submitted to social security; you can't make an appointment with the decision makers. All you can do is make sure every scrap of relevant paper gets to their office.

They may send him for a disability eval (or 2 since he is claiming physical and psychiatric issues). That's at their discretion and cost.

The reconsideration period is unfortunately not the time most likely to get approval. About 30% of people are approved initially and a smaller number in reconsideration. Then a lot more are approved with the judicial review which can take a long time depending on your state. It doesn't really seem there is a good way to look at a case from the outside (a disability attorney might be able to) and know what approval will take. However, that you have an attorney means the attorney thought there was a good chance of approval or he wouldn't have taken the case.
