MedPay Arizona car insurance pays your medical bills the moment you file the claim, regardless of who caused the crash. The ER bill arrives before your health insurance processes anything, and MedPay is the coverage most Arizona drivers skipped without understanding what the waiver actually costs them. As of 2025, that gap is getting more expensive.
Key Takeaways:
- MedPay pays regardless of fault. It covers your medical bills and your passengers’ bills immediately, before any liability determination is made under Arizona’s tort system.
- MedPay covers your health insurance deductible and copays. On a $5,000 hospital bill with a $2,500 deductible, MedPay pays your out-of-pocket portion your health plan won’t touch.
- Arizona carriers are required to offer MedPay under the ARS 20-259.01 framework, but you can waive it in writing. Most drivers waive it without understanding what that waiver costs them.
What Is MedPay on an Arizona Car Insurance Policy?

MedPay, or Medical Payments Coverage, is a first-party benefit on an Arizona auto policy that pays medical expenses for you and your passengers after a crash, regardless of who caused the accident. This means you do not wait for a fault determination, a liability investigation, or an at-fault driver’s carrier to accept responsibility. The claim goes to your own carrier, and the bills get paid.
The practical scope matters here. MedPay covers the named insured, household family members, and any passengers riding in the covered vehicle at the time of the accident. It also covers you as a pedestrian struck by a vehicle. This is not liability coverage, which pays the other driver’s medical bills when you cause a crash. It is not UM/UIM coverage under the ARS 20-259.01 framework, which pays when an uninsured driver hits you. MedPay is the piece that pays your own body, your own bills, before anything else in the claim process moves.
MedPay limits in Arizona typically run $1,000 to $10,000 per person. That range is set by carrier filing, not by statute. Per standard personal auto form practices filed with the Arizona Department of Insurance and Financial Institutions, carriers have discretion on the limit options they offer.
MedPay is optional in Arizona. Carriers must offer it, but you can waive it in writing, and most drivers do exactly that. The question worth asking before you sign the waiver is whether your health plan picks up every dollar MedPay would have covered. In most cases, it does not. Policy language varies by carrier, so consult a licensed Arizona agent for advice specific to your policy before waiving this coverage.
For broader context on how this fits the arizona insurance guide framework for auto coverage, MedPay sits alongside UM/UIM and liability as one of the three layers that protect the people inside your vehicle, not just the vehicle itself.
MedPay vs. Health Insurance: How the Two Actually Interact After a Crash

The common assumption is that health insurance makes MedPay redundant. The reality is that health insurance and MedPay cover different portions of the same bill, and understanding that split is what makes the coverage decision clear.
| Feature | MedPay | Primary Health Insurance |
|---|---|---|
| Fault requirement | None. Pays regardless of who caused the crash. | None for coverage, but may require pre-authorization or referral. |
| Who is covered | Named insured, household members, all passengers in the vehicle. | Named insured and dependents on the plan only. |
| What triggers payment | Filing a claim with your own carrier after a covered accident. | Filing a claim after receiving covered medical services. |
| Deductibles and copays | No deductible or copay on MedPay itself. | Your plan’s deductible and copay apply before benefits pay. |
| Claim filing speed | Typically pays within days of submitting bills. | Subject to the plan’s processing cycle and any pre-authorization steps. |
| Subrogation rights | Carrier may seek reimbursement from a liability settlement. | Health plan may also seek reimbursement if you recover from the at-fault driver. |
| Lost wages | Not covered. | Not covered (separate from disability coverage). |
The coordination of benefits works like this: health insurance is typically primary, meaning it pays according to your plan’s schedule first. MedPay is secondary. It picks up what health insurance leaves unpaid, and what health insurance leaves unpaid is almost always your deductible and copay.
A $5,000 ER bill with a $2,500 in-network deductible leaves you owing $2,500 before your health plan pays a single dollar. MedPay covers that gap up to your policy limit. The arizona car insurance claim payout process treats these two coverages as sequential, not competing.
The subrogation wrinkle is worth knowing. Some health plans have a right of reimbursement if you later recover money from the at-fault driver’s liability coverage. If that happens, MedPay has already paid your immediate bills, giving you time to pursue the liability claim without carrying out-of-pocket medical debt in the meantime.
Benefits coordination rules vary by health plan type. Review your health plan’s coordination of benefits provision or speak to a licensed agent before assuming your health insurance covers everything a crash could cost you.
How Fast Does MedPay Pay, and Why That Matters in Arizona’s Tort System

Arizona is a fault state. After a crash, the liability determination process, meaning figuring out whose insurance pays and how much, takes weeks to months. If the other driver disputes liability, that timeline extends further. Medical bills do not wait for that process to finish.
MedPay pays immediately because fault is irrelevant to the claim. The practical sequence works like this: you go to the ER, you file your MedPay claim with your own carrier, and your bills get paid while the liability investigation is still running. You are not negotiating with the other driver’s carrier. You are not waiting for an adjuster to accept responsibility. Your MedPay claim is processed on its own track.
Contrast that with waiting for the at-fault driver’s carrier to accept liability under Arizona’s minimum limits structure. Per ARS 28-4009, Arizona’s minimum liability limits are $25,000 per person, $50,000 per accident, and $15,000 for property damage. A serious injury, a hospital admission, surgery, follow-up care, can exhaust the per-person limit before the hospital bill is finalized. The article on how much liability coverage an Arizona driver should carry explains why those minimums fall short in practice.
MedPay is not a substitute for UM/UIM coverage under the ARS 20-259.01 framework. Those are different problems. UM/UIM protects you when the at-fault driver has no insurance or not enough. MedPay covers the days and weeks before any liability settlement resolves, regardless of who has what coverage. Think of it as the bridge between the crash and the claim outcome.

What Does MedPay Cover, and What Does It Exclude?

MedPay covers your body and your passengers’ bodies after a covered accident. It does not cover your car, the other driver, or your income. That distinction matters, and it connects directly to the full coverage misconception that shapes how most Arizona drivers think about their auto policy.
“Full coverage” in Arizona colloquially means comprehensive and collision coverage. Neither of those pays your medical bills. Comprehensive covers your car when it’s damaged by something other than a collision. Collision covers your car when you hit something. MedPay is the piece that covers the people inside the car. Many drivers carrying “full coverage” have no medical payment benefit at all.
What MedPay covers:
- Emergency room visits and urgent care following a covered accident, including triage and stabilization costs.
- Ambulance transport to the hospital, whether ground or air, when medically necessary.
- Hospital stays, surgery, and anesthesia related to injuries sustained in the crash.
- X-rays, imaging, and diagnostic procedures ordered as part of accident injury treatment.
- Dental treatment required because of injuries from the accident, such as broken teeth from airbag deployment.
- Funeral and burial expenses, in the event of a fatality, up to the policy limit. Exact coverage varies by the policy form your carrier uses.
- Prosthetics and medical equipment prescribed as part of accident injury recovery.
What MedPay does not cover:
- Lost wages from time off work during recovery. That is a separate disability or wage-loss benefit, not a MedPay function.
- Property damage to your vehicle or anyone else’s. That is handled by collision coverage or the at-fault driver’s liability limits.
- Pain and suffering or other non-economic damages. Those are tort claims against the at-fault party.
- Injuries to the other driver or their passengers. That is what your liability coverage under the Arizona Revised Statutes minimum requirements addresses.
- Injuries that occur while committing a crime or operating the vehicle in an excluded use.
Most Arizona personal auto MedPay endorsements cover reasonable and necessary medical expenses incurred within three years of the accident date. The exact window is defined in the policy form, not by statute. Confirm what your declarations page shows, because covered expenses vary by the specific form your carrier filed with DIFI.
For a sense of how coverage gaps accumulate across a policy, the slow leak vs burst pipe coverage analysis on the homeowners side shows the same pattern: the coverage you assumed you had and the coverage that actually pays are often different things.
Do You Need MedPay If You Already Have Health Insurance in Arizona?

The question has a direct answer: it depends on your health plan’s deductible, not on whether health coverage exists. Here is the decision framework.
Check your health insurance deductible. If your deductible is above $1,500, MedPay pays for itself after one ER visit. High-deductible health plans in the U.S. had a minimum deductible of $1,650 for self-only coverage in 2025 per IRS guidelines. At that threshold, a single post-crash ER visit can exhaust MedPay limits and still leave a balance. If your deductible is $3,000 or higher, the question answers itself.
Check whether your health plan covers accident-related care without pre-authorization. Some plans require referrals or pre-authorization steps that slow payment. MedPay has no such requirement. It pays on submitted bills.
Consider your passengers. MedPay covers everyone in your vehicle. Your health insurance covers only you and your enrolled dependents. If you regularly carry friends, coworkers, or family members who are not on your health plan, MedPay is the only medical coverage they have inside your car.
Ask your agent for a quote with and without MedPay. At $5,000 in coverage, MedPay adds a modest amount to your annual premium. The exact figure varies by carrier and driving record, but the cost-to-benefit math typically favors carrying it. Get the specific number for your profile before deciding.
If you have a high-deductible health plan or no health insurance, carry MedPay. With an HDHP, your out-of-pocket exposure in the first days after a crash is at its highest. MedPay covers exactly that window. Without any health insurance, MedPay is the only medical coverage you have for accident-related care before any liability settlement arrives.
However, if your health plan has a $500 deductible, no coinsurance, and covers accident-related care without authorization delays, the case for MedPay is narrower. It still covers your passengers, and the premium difference is small, but the personal financial exposure is lower.
Premium impact varies by carrier and driver profile. Get a specific quote from your agent before waiving MedPay in writing. The same principle applies when reviewing any coverage layer, whether you are checking motorcycle insurance in Arizona or reviewing solar panel storm damage claim language on a homeowners policy: know what you are waiving before you sign.
Frequently Asked Questions
What is MedPay on a car insurance policy in Arizona?
MedPay, or Medical Payments Coverage, is a first-party benefit on an Arizona auto policy that pays medical expenses for you and your passengers after a crash, regardless of who caused the accident. It is optional in Arizona. Carriers must offer it under the ARS 20-259.01 framework, but you can waive it in writing. Unlike liability coverage, which pays the other driver’s bills when you cause a crash, MedPay pays your own bills.
Does MedPay cover my passengers in an Arizona accident?
Yes. MedPay covers the named insured, household family members, and any passengers riding in the insured vehicle at the time of the accident, all regardless of fault. Your primary health insurance covers only you and your enrolled dependents, not friends or other riders in your car. MedPay fills that gap for everyone in the vehicle.
Can I use MedPay and health insurance at the same time after a crash?
Yes, and in most cases you should use both. Health insurance is typically primary and pays first according to your plan’s benefits. MedPay then covers what health insurance leaves unpaid, most often your deductible and copays. Some health plans have subrogation rights and may seek reimbursement from any liability settlement you receive later. Review your plan’s coordination of benefits provision or speak to a licensed agent to understand how the two interact under your specific coverage.
