You don't need to worry as this is not serious. May even not increase your insurance depends which company.
As long as that guy claimed, your insurance company and police will know. You will then be contacted by the claims adjuster assigned to your file. In your case the entire claim will be very likely handled over the phone. The adjuster even don't need to meet you in person. If they do call you, you just explain what happened and minimized it (you can send picture to prove how minor the collision is).
Your insurance won't pay for the loss but that guys' insurance will do even you are at 100% fault.
