I would go see a NYC accident lawyer and there are attorneys who specialize in bike accidents. Make sure to memorialize everything that occurred on paper, get the med reports asap and do not post anymore here on Bike forum. You could PM somebody, but do not post publicly. Anything you write here can be used against you.
Sounds like doored you and he needs to pay up for a bunch of things due to his negligence. Best.
BTW - I got busted up pretty good by a jerk in Central Park and when it came time to pay - he left the city permanently to become a Rabbi in some podunk part of the United States.
