If all you did was inquire or make an appointment and didn't follow through, you don't have a claim that can be reopened. No claim, no reopening. If you got a written denial with appeal rights, you had 60 days to file a formal appeal. If your denial was for failure to cooperate, and you didn't appeal and now, one year, two years later you want to cooperate, you are too late. If you did file a claim and were denied because you were found not disabled, there can be reopening of old claims because of new and material evidence, but reopening is discretionary. Your prior denied claim may or may not be reopened.

But if all you did was drop the ball and didn't follow through, it is doubtful there is anything to reopen.

Did you file a claim or not? Did you get a formal notice of denial with appeal rights or not?
