"My uncle, who is a retired police sargeant, has told me to never contact my insurance company about an accident when the other guy is at fault, unless the other guy's insurance plays hardball. He said that your insurance company can hold your claims against you even if they never pay out a dime. I don't know if he is correct or not, but it is now something I avoid unless the at-fault driver tries to weasel his way out... "
Your uncle is wrong. Maybe it used to be like that, but not now. Now the insurance companies have C.L.U.E. (Comprehensive Loss Underwriting Exchange). All the insurance companies report to CLUE, and all of them buy information from them.
All incidents are reported and show up on the record. If you're a victim of adverse underwriting (aka high premiums) because of a not-at-fault incident, it's up to you to explain it and get your insurance company to confirm it. You had an accident and didn't report it? They're probably going to view you as a bad-risk, scum-sucking, lying loss-waiting-to-happen. And that means high premiums.
I believe this CLUE is also tied up with your credit report. Your premiums will be higher if you have a low credit rating, and vice versa. I think it stinks, and I think it should be illegal, but no one has ever asked for my opinion.
Actually, hardly anyone ever ASKS for my opinion. They get it, but they don't ask for it...

First, everything is reported as an incident, then maybe an accident, then maybe a claim. Even if unattended by the police, I think by law you're suppose to report all vehicle property damage losses in excess of $500 to law enforcement.
