Sorry to hear about your accident. Glad you're ok.
Hate to be a Debbie downer, but your compression material under the bumper skin should be replaced as well. Based on how she hit you on the corner of the car and the lack of area over which the force of impact could have been distributed, you may even find some minor bends in the frame under the bumper itself.
Could you just replace the skin and forget about it? Maybe.
Is it completely irresponsible and, at the very least, unethical? Yup.
If you DIY, replace everything that needs to be replaced to ensure that the right impact protection is there in case it is ever needed (by you or the car's next owner)...or you can do it the easy way and go through insurance.
