How Car Insurance Can Help with Your Medical Bills

After a crash, medical bills can arrive long before anyone agrees who was at fault. Several different coverages can pay them. Which one pays first depends on your state and your policies.

The coverages that pay medical bills

Personal injury protection (PIP). It's required in the 12 no-fault states (Insurance Information Institute) and available in some others. It pays medical bills for you and your passengers whoever was at fault, and, depending on the state, lost income and essential services.
Medical payments (MedPay). It pays medical and funeral costs for you and your passengers up to a modest limit, regardless of fault. It's optional in most states.
The other driver's bodily injury liability, if they caused the crash. It pays your medical costs, lost income and, depending on the state, pain and suffering, but usually only after fault is settled.
Your uninsured/underinsured motorist coverage, if the at-fault driver has no insurance or not enough. See accidents with uninsured drivers.
Your health insurance, which may pay first in some situations and then seek repayment from the auto insurer.

In a no-fault state

You claim first on your own PIP, whoever caused the crash. You can step outside no-fault and claim against the at-fault driver only when your injuries meet the state's threshold: a legal description of serious injury in Florida, Michigan, New Jersey, New York and Pennsylvania, or a set amount of medical costs in Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota and Utah (Insurance Information Institute).

In an at-fault state

The at-fault driver's liability insurance is responsible, but payment usually comes as a settlement at the end. Meanwhile, MedPay or your health insurance can cover bills as they come in, and some policies then recover the money from the at-fault insurer.

Practical steps

Get medical attention promptly and keep every record and bill.
Report the accident to your insurer quickly. Most policies require prompt notice.
Tell medical providers which auto coverage applies, and give them your health insurance too.
Don't sign a release or accept a final settlement until your treatment is complete and costs are known.
For serious injuries, consider talking to an attorney before settling.

How much MedPay or PIP to carry

In no-fault states the law sets a minimum PIP amount, and many insurers offer higher options. Where MedPay is optional, consider your health insurance deductible and out-of-pocket maximum, and whether you often carry passengers who may not have good health cover. MedPay is typically inexpensive, and it pays regardless of fault, without waiting for a liability settlement.

Health insurance, Medicare and repayment

If your health plan pays for accident injuries, it may have the right to be repaid from any later settlement with the at-fault driver's insurer. Health plans and Medicare often place a lien or claim on the settlement. Medicare is generally a secondary payer when auto insurance (no-fault, MedPay or liability) is responsible, so the auto coverage is expected to pay first. Tell your insurers and providers about all your coverage so bills go to the right place, and factor any repayment into what you accept in a settlement.

Quick answers

Who pays my medical bills if the other driver was at fault? In an at-fault state, their liability insurer ultimately, usually as a settlement. MedPay or health insurance can pay in the meantime. In a no-fault state, your own PIP pays first.

Do passengers get covered? Yes. PIP and MedPay on the car's policy usually cover passengers, and passengers can also claim against an at-fault driver.
