Sorting out multiple insurance policies accident Arizona claimants deal with often confuses people more than the crash itself. A single accident can touch your own auto policy, the other driver’s liability coverage, your health insurance, and sometimes an umbrella policy, all at once. Each one pays for something different, and they don’t apply in a random order.
The typical order coverage applies
MedPay or PIP first
If your policy includes MedPay coverage, it usually pays first, regardless of fault, and it pays fast. It covers medical bills up to your policy limit, often within days of submitting bills.
The at-fault driver’s liability coverage
Once fault is established, the other driver’s liability insurance becomes the primary source for your broader damages: medical bills beyond MedPay, lost wages, and pain and suffering.
Your UM/UIM coverage, if needed
If the at-fault driver has no insurance, or not enough to cover your losses, your own UM/UIM coverage steps in to fill the gap.
Health insurance, as a backstop
Health insurance can cover treatment costs while a claim is pending, though most health plans hold a right to reimbursement once you settle. That reimbursement right often surprises people at the end of a case.
Why the order matters
Coverage sources interact instead of simply stacking on top of each other. MedPay pays your bills first, but the MedPay insurer can later seek reimbursement from your settlement once you recover from the at-fault driver, typically for amounts above $5,000. That’s a subrogation claim, separate from the payout itself.
UM/UIM works differently. Under A.R.S. § 20-259.01(G), an insurer can’t offset your UM/UIM payout by the amount MedPay already paid. The two coverages don’t cancel each other out on that side of the equation, even though MedPay and the at-fault driver’s liability coverage often do interact through subrogation.
Skipping a step in the order can also cost you money you were entitled to. Submitting bills to health insurance without first using available MedPay, for example, can mean losing coverage that would have applied at no cost to you.
A practical example
Say a driver with no insurance hits you. You have $10,000 in MedPay and $50,000 in UM coverage. MedPay pays your medical bills first, up to $10,000. Your UM coverage then covers the remaining damages, including lost wages and pain and suffering, up to its own limit, without any reduction for the MedPay already paid. Health insurance never enters the picture in this scenario, because your own auto coverages already handle it.
The bottom line
Multiple insurance policies after an accident in Arizona work more like a sequence than a menu. Knowing the order, MedPay first, at-fault liability next, UM/UIM as a backstop, and health insurance last, keeps you from leaving coverage on the table or repaying money you never needed to borrow against your own settlement.
