1.) First, rely on your own health insurance policy. If you have primary health insurance, use it to cover your medical bills. You definitely don't want your doctor to send your account to collections.
2.) Next, review your auto insurance policy. Some policies include medical payment coverage. If you are unsure if your policy does, contact your auto insurance agent and check the limits of the coverage if you have it.
3.) The insurance ompany for the at-fault driver ultimately will be responsible for your medical bills. However, because the insurer won't pay until the end of the claim, you need to look on your own insurance first.
