Hello, my name is Mark and I will try help you.
Was the vehicle that hit you coming towards your open door or from behind you into the open door?
That is the worst kind of contact because there is a possibility that the 'A' pillar may have been twisted as well as damage to the door frame.
For that reason I would probably go through the insurance. However I would still obtain a few quotes from different bodyshops and get them to asses the damage. You might be lucky and have no damage to the pillar. Only you can tell if the quotes you get make it worthwhile to claim or not depending on the excess you have to pay.
