No, no ticket, no report, no knowledge to insurance company.
ask your police department, they are the ones who issued the code
I hope you called the police. Police will come since that occurred on a public street. Was a ticket issued to one party? Without a ticket issued, the insurance company will most likely make it 50-50 responsibility. The car which stopped doesn't have the right to stop there, but you also, should have noticed and not opened the car door so far. It sounds less like the parked car's fault, but insurance companies rule unless you go to court with a lawsuit.
Not if it happened on private property and generally speaking if you weren't issued a ticket at the scene of the accident you most likely won't get one later. The insurance company can't issue a citation. Only the police can do that.
It depends on the state and the insurance company.
It depends on your insurance company police terms and conditions.
