<human>: I (23/f) got rear ended on March 22, 2014. The other driver was uninsured and told me her insurance was going to start the beginning of April. We exchanged information. I took a picture of the damage which was very minor to the vehicles. I did not call the police since the damage was so minor ($850 to the back bumper of my Outback). 

I leave the scene of the accident and go to lunch with my boyfriend and mom. I started getting nauseous and was having problems speaking. We are concerned I have a concussion and decide to go home. I call my insurance company and begin that process. I end up going to the ER. I get two CAT scans and I am there for about 2 hours.

My boyfriend and I left for our preplanned vacation the night of the accident. I spoke with my insurance company and they were having problems reaching the person who hit me. My insurance company urged me to file a police report. I did so. I received periodic updates that they were still unable to reach her.

I received a bill for the ER visit for $895. Insurance had covered about $4500 but now I'm stuck with the remaining $895. What are my options? Do I take her to small claims court? Do I suck it up and pay the bill? Do I try disputing the bill with the hospital?

Could you distill the essence of the text into 1-3 sentences?
<bot>: got rear ended by uninsured driver, insurance company could not reach driver, I am responsible for $895 to the hospital. Unsure what my options are.
