Wow. Every state seems to be different in awarding SSDI. I was awarded SSDI at the end of my hearing.

I had also gone through the three denials before I received a hearing.

But I know of a person who didn't go through any denials and received SSDI on the first try.

Different illnesses, different states, different judges. There doesn't appear to be any uniformity in their method of decision.

If I remember correctly, if you don't receive a favorable hearing, you may be able to appeal the decision within a certain time frame.

Lots of information at social security website.
