PIP & med-pay rules in Arizona

Right after a crash, the question that hits first is usually practical: who pays my medical bills? In Arizona, the answer is not what drivers coming from a no-fault state expect. Arizona has no personal injury protection (PIP) and no no-fault system. It is a pure tort, at-fault state, so the driver who caused the wreck is responsible for the harm, and you recover by making a claim against that driver's liability insurance.¹ The only mandatory auto coverage in Arizona is liability, which pays the people you injure, not your own bills.¹

That gap between the crash and a settlement is where two optional pieces of coverage matter: medical payments coverage (med-pay) and uninsured or underinsured motorist coverage. How Arizona treats each one, and the specific dollar rules attached to them, is what changes how much money actually reaches you.

Why there is no PIP in Arizona

PIP is a first-party, no-fault benefit that pays your medical costs quickly regardless of fault. It is standard in states like Florida and Michigan. Arizona never adopted a no-fault scheme. The statute that sets Arizona's insurance requirement, A.R.S. § 28-4009, requires only liability coverage and says nothing about PIP or first-party medical benefits.¹ The Arizona Department of Insurance and Financial Institutions (DIFI) describes the state's system the same way: at-fault, with no PIP requirement.²

The practical effect is a timing problem. The at-fault driver's insurer usually will not pay your treatment bills as you go. It settles once, often after you have finished treatment, and only if fault and damages are agreed. In the meantime, your providers still expect to be paid. Med-pay, your own UM/UIM coverage, and your health insurance are what fill that space.

What med-pay does, and why it is optional

Medical payments coverage sits on your own auto policy. It pays reasonable and necessary medical (and often funeral) expenses for you and your passengers after a crash, up to the limit you bought, with no deductible and no fault requirement.² It pays even if the crash was your fault, and even while a liability claim is still being fought over.

Med-pay is optional in Arizona. Drivers are not required to buy it, and insurers are not even required to offer it. That last point is a real distinction. Under A.R.S. § 20-259.01, insurers must offer uninsured and underinsured motorist coverage in writing, but there is no parallel mandatory-offer rule for med-pay.³ DIFI lists med-pay among the optional coverages a driver can choose to add.² Limits are usually modest, commonly $1,000 to $10,000, which is enough to cover an ER visit, imaging, or the deductibles and copays your health plan leaves behind.

The Arizona med-pay lien cap: the $5,000 rule

Here is the Arizona-specific rule that most drivers never hear about, and it can put money in your pocket. When your med-pay insurer pays your bills, can it demand that money back out of your eventual settlement with the at-fault driver? In Arizona, only partly.

A.R.S. § 20-259.01(J) lets a med-pay insurer place a lien only "against any amount in excess of $5,000" it paid under the medical payments coverage, and only for an injury from an accident that occurred after December 31, 1998.³ In plain terms, the first $5,000 of med-pay benefits is yours to keep, even after you recover from the person who hit you. If your med-pay limit is $5,000 or less, the insurer generally has no lien at all and gets nothing back.

The statute also puts procedure around the lien. The insurer has to record it within 60 days of issuing a payment above $5,000, and it "shall compromise the lien in a fair and equitable manner."³ So even on larger payouts, the reimbursement can be negotiated down rather than collected in full. If a med-pay adjuster claims the whole amount back on a small policy, that claim is not what the statute allows.

UM and UIM coverage carry more weight here

Because there is no PIP and Arizona's required liability limits are low, your own uninsured and underinsured motorist coverage is often the thing that actually pays for a serious injury. Arizona requires insurers to make both available. Under A.R.S. § 20-259.01, the insurer must offer UM and UIM in writing at limits equal to your bodily injury liability limits, and you can buy lower limits or reject the coverage, but the rejection has to be in writing.³ Your policy declarations page is treated as that written record.³ DIFI likewise frames UM and UIM as optional coverages the insurer must offer and you decide whether to take.⁴

Uninsured motorist coverage steps in when the at-fault driver has no insurance or flees the scene. Underinsured motorist coverage applies when the at-fault driver has insurance but not enough to cover your injuries. Given how thin the minimum limits are, that second scenario is common.

Minimum liability limits are lower than a hospital bill

For policies issued or renewed on or after July 1, 2020, Arizona's minimum liability limits are $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage, written as 25/50/15.¹ Before that date the minimums were 15/30/10.¹ A single night in the hospital can exhaust $25,000, so relying on an at-fault driver who carries only the minimum is risky. That is the practical reason med-pay and UIM exist.

Deadlines and how fault affects your recovery

Two more Arizona rules shape any injury claim. First, the deadline. You generally have two years from the date of the crash to file a lawsuit for personal injury, and the same two-year limit covers damage to your property, both under A.R.S. § 12-542.⁵ Miss it and the claim is usually gone, no matter how strong.

Second, your own fault does not erase your claim. Arizona follows pure comparative negligence. A.R.S. § 12-2505(A) states that a claimant's action "is not barred, but the full damages shall be reduced in proportion to the relative degree of the claimant's fault."⁶ Even a driver found 80 percent at fault can still recover the other 20 percent. Arizona also does not cap the compensatory damages you can recover in an ordinary crash case, under Article 2, Section 31 of the state constitution.⁷

Your car is a separate claim

Med-pay covers people, not property. If your vehicle was damaged, that is a separate claim against the at-fault driver, and it can include the diminished value of a car that is worth less after a repaired wreck. To document any claim, start with the official crash report; how to get one is covered on the Arizona crash reports page. If the bills, liens, and layers of coverage are getting complicated, an attorney can sort out which policy pays first, and you can find one through the legal directory.
