Here's a website that is NYC specific:

A couple of important items.
There's a 30 day window from the accident to file your claim with the motorist's insurance company. That clock is ticking.
You will need the NYPD accident report. This isn't as easy as it sounds. Hopefully, the cop filed the report and entered it into the system in a timely maner. The clock is still ticking, whether he did or did not.
It's at the local precinct. You will need $10 in check/money order to get a copy. They don't trust the cops with cash. Personal checks are OK. You will probably need a lawyer because NYC's MV-104 does not list the insurance company in plain text.
Here's the relevant section of the VTL:
§ 1214. Opening and closing vehicle doors. No person shall open the door of a motor vehicle on the side available to moving traffic unless and until it is reasonably safe to do so, and can be done without interfering with the movement of other traffic, nor shall any person leave a door open on the side of a vehicle available to moving traffic for a period of time longer than necessary to load or unload passengers.
There's a more specific NYCDOT Rule:
§ 4-12 (c) Getting out of vehicle. No person shall get out of any vehicle from the side facing on the traveled part of the street in such manner as to interfere with the right of the operator of an approaching vehicle or a bicycle.
