March 2006?

For SSDI claims, there is a 4 year limit on reopening and there has to be new and material evidence that the previous decision was incorrect by review of evidence dated on or before the date the decision was made. The fact that you are worse off now than you may have been on March 6th or March 2006 doesn't change the fact that the denial may have been correct on that date.

Can't tell much from your posts. It's all speculation. Best answer is "maybe".
