Insurance settlements and payment for medical bills

I was involved with a third party car accident. They are calling it a low impact accident since my car had $650 in damage. However, it didn't feel low impact and I was diagnosed with whiplash. I've been receiving treatment and my medical bills are approximately $4900. I'm in the process of trying to settle with the insurance company. I've been reading I should ask for 3 times my medical bills as a starting point. Should that include the payment of the medical expenses or not? What is a fair and reasonable settlement. I still have neck pain and I fly a lot for work which adds to the issue. I'm a supervisor for a multinational engineering firm. I'm never had an injury related car accident claim before and looking for advice.
