Possibly. You should talk to a NYC area NY licensed workers' comp lawyer immediately. It may be too late for you to file a new claim.
From the facts you've given, I will assume you were working for a New York company. If that's the case, then you should be filing for workers' comp in New York. If you were working for a California company but briefly in N.Y., then you would file in CA. Workers' Comp. law is state law so there are 50 different sets of w.c. laws in this country (maybe more if you count Guam, D.C., P.R., etc.). Out here, most of us know nothing about N.Y. law. Go to www.avvo.com to find a good w.c. attorney in N.Y. and ask.
In the legal business we have what we call call statutes of limitations. They set the time limits within which any action must be brought. You're now 11 years post 09/11/2001. That may be beyond the statute of limitations for w.c. cases in N.Y. Don't walk....run to talk to a N.Y. attorney about this.
