No-Fault insurance - I was injured as a passenger with uninsured driver?

My boyfriend was rear-ended while I was a passenger in his car. I suffered broken ribs and whiplash, and need help paying medical expenses. Unfortunately, we live in a no-fault insurance state and he did not have car insurance. Under no-fault insurance, his insurance company would normally pay for my medical expenses, but because he doesn't have any, is there any way to collect any money without suing my boyfriend!?
