Accident built, when to report the insurance?

hello, so yesterday I built an accident, my car is a bit demolished and his even more. police has come and has noted the damage. probably will get a write in a few weeks by the police. when should I report my insurance the accident? actually got nothing from the police and the damaged… and another stupid question from me, I am insured with the axa and that: performance overview: mobile online building blocks: cover plus is a “partial cascade m so the vehicle from the damaged pays my insurance and then nothing with me?
