- Bodily injury liability pays for others’ injuries when you’re at fault — not your own medical bills.
- Medical payments (MedPay) covers you and your passengers regardless of fault, up to your policy limit.
- Health insurance can cover accident injuries but may require deductibles, copays, and reimbursement later.
- MedPay and health insurance can work together, but coordination rules vary by state and policy.
- Understanding who pays first prevents surprise bills and financial gaps after a crash.
What is bodily injury liability coverage?
Bodily injury liability coverage pays for medical expenses, lost wages, and legal costs for other people if you cause a car accident.
It does not cover your own injuries.
Most states require drivers to carry bodily injury liability insurance with minimum limits (for example, 25/50 or 50/100). However, serious accidents can exceed minimum limits quickly — especially when hospital stays, surgeries, or long-term rehabilitation are involved.
What it typically covers:
- Emergency medical treatment
- Hospital bills
- Rehabilitation
- Lost wages
- Pain and suffering
- Legal defense if you’re sued
What is medical payments coverage (MedPay)?
Medical payments coverage — often called MedPay — helps pay medical expenses for you and your passengers after an accident, regardless of who caused it.
It’s optional in many states and usually offers lower limits (commonly $1,000 to $10,000).
What MedPay typically covers:
- Ambulance fees
- Hospital visits
- X-rays and diagnostics
- Surgery
- Funeral expenses
How it differs from bodily injury:
- Pays your medical bills
- No fault required
- No deductible in most cases
MedPay is especially helpful if you:
- Have a high health insurance deductible
- Don’t have strong health coverage
- Want fast medical bill payment without waiting for fault determination
How does health insurance fits in?
Health insurance can cover accident-related injuries, but it works differently from auto insurance.
You may still owe:
- Deductibles
- Copays
- Coinsurance
- Out-of-network charges
In some cases, your health insurer may seek reimbursement if you later receive a settlement from an at-fault driver’s insurance (a process called subrogation).
Important distinction:
Health insurance pays for your care — but it does not cover:
- Lost wages
- Pain and suffering
- Legal costs

Who pays first after an accident?
The order of payment depends on:
- Who was at fault
- Your state’s insurance laws (fault vs. no-fault)
- Whether you carry MedPay or PIP
- Your health insurance terms
Common scenarios
If you cause the accident:
- Your bodily injury liability pays for others.
- Your MedPay may cover your own medical bills.
- Your health insurance may cover remaining costs.
If another driver is at fault:
- Their bodily injury liability should pay your medical costs.
- Your MedPay may pay first while fault is determined.
- Your health insurance may step in if needed.
Bodily Injury vs. MedPay vs. Health Insurance: Quick Comparison
| Coverage Type | Covers Your Injuries? | Covers Others’ Injuries? | Fault Required? | Covers Lost Wages? |
|---|---|---|---|---|
| Bodily Injury Liability | ❌ | ✅ | Yes | ✅ |
| MedPay | ✅ | Sometimes (passengers) | No | ❌ |
| Health Insurance | ✅ | ❌ | No | ❌ |
When you might need more coverage
You may need higher limits or additional coverage if you:
- Own a home or have significant savings
- Have high income or future earning potential
- Frequently drive with passengers
- Live in a high medical-cost area
- Have a high-deductible health plan
Drivers with significant assets may also consider an umbrella policy to extend liability protection beyond auto policy limits.
Common coverage gaps drivers miss
- Assuming bodily injury covers their own injuries
- Relying only on state minimum liability limits
- Not carrying MedPay with a high health insurance deductible
- Forgetting that health insurance doesn’t cover lawsuits
- Not understanding reimbursement rules after settlements
Frequently Asked Questions: MedPay
Is your health or car insurance medical coverage primary?
Typically, your car insurance medical is primary and your health insurance is secondary if you carry both, but this can vary by state.
If both your health insurer and car insurer pay for medical bills, will your health insurer ask to be reimbursed for claims they paid on?
The answer is usually yes if insurers paid out overlapping payments for the same medical expenses.
Does bodily injury coverage pay my medical bills?
No. Bodily injury liability covers injuries you cause to others. To cover your own medical bills, you would need MedPay, personal injury protection (PIP), or health insurance.
Should I carry MedPay if I already have health insurance?
It can still be valuable. MedPay often has no deductible and pays quickly, which can reduce out-of-pocket costs and avoid using health insurance for smaller claims.
What happens if medical bills exceed liability limits?
If damages exceed policy limits, the at-fault driver may be personally responsible for the remaining amount. This is why higher liability limits or umbrella insurance are recommended for asset protection.
Is MedPay required by law?
In most states, MedPay is optional. However, some states require personal injury protection (PIP), which functions similarly but may cover additional expenses like lost wages.
Can health insurance deny accident-related claims?
Health insurance generally covers accident injuries, but out-of-network care, exclusions, or policy limitations may apply. Coordination of benefits rules may also affect payment order.
