When I has hit by a car in NY, I was told by the hospital to notify my insurance co. to get the claim in the "system". They denied it within an hour and contacted the insurance co. of the lady that hit me. After her insurance was notified, all medical bills were sent to her insurance. I got an estimate for the damages to my bike, helmet, clothes etc. and sent it to her insurance company. After they sent an appraiser and verified the damages were accurate, they sent me a check for the property damage.

Your state may have a different procedure. But then in NY it does help that ALL car/bike collisions are the liability of the motorist, or so said my attorney.
