UM/UIM Claims and Medical Payment Coverage in Illinois

Home > Blog > UM/UIM Claims and Medical Payment Coverage in Illinois

Two Coverages That Work Together

Medical payment coverage (MedPay) and uninsured/underinsured motorist coverage (UM/UIM) are both first-party coverages on your auto insurance policy, meaning they both pay benefits to you regardless of who caused the accident. While they serve different purposes, they can work together to maximize your recovery after an accident with an uninsured or underinsured driver.

Understanding how these coverages interact helps you make the most of the insurance protection you already have.

What MedPay Covers

Medical payment coverage pays for reasonable medical expenses resulting from a car accident, regardless of fault. MedPay typically covers hospital bills, surgery costs, X-rays and diagnostic imaging, ambulance fees, dental work necessitated by the accident, and some funeral expenses. MedPay limits in Illinois commonly range from $1,000 to $25,000, though higher amounts may be available.

The key advantage of MedPay is speed. There is no need to prove fault or negotiate liability. You submit your medical bills, and MedPay pays them up to the policy limit. This can be critical in the weeks immediately after an accident when bills are piling up and you may not yet have received any other insurance payments.

How MedPay and UM/UIM Work Together

MedPay and UM/UIM coverage are not duplicative—they cover different aspects of your losses. MedPay covers medical expenses only, up to a relatively low limit, and pays regardless of fault. UM/UIM coverage provides broader compensation including medical bills, lost wages, pain and suffering, and other damages, but only when the at-fault driver is uninsured or underinsured.

In a typical accident with an uninsured driver, you might use MedPay to cover your immediate medical bills while your UM claim is being processed. The UM claim, which can take longer to resolve, would then compensate you for the full range of your damages including medical expenses beyond your MedPay limit, lost income, and pain and suffering.

Does MedPay Reduce Your UM/UIM Recovery?

A common concern is whether using MedPay will reduce the amount you can recover under your UM/UIM coverage. In Illinois, the answer depends on your policy language. Some policies contain setoff provisions that allow the insurer to credit MedPay payments against the UM/UIM recovery. Others treat the two coverages as completely independent.

Even if your insurer claims a setoff, the practical effect may be minimal. MedPay covers only medical expenses, while UM/UIM covers a broader range of damages. The non-medical components of your UM/UIM claim—lost wages, pain and suffering, loss of normal life—are generally not affected by MedPay payments.

Maximizing Both Coverages

If you have been injured by an uninsured or underinsured driver, file your MedPay claim immediately to get your medical bills covered quickly. Then pursue your UM/UIM claim for the full value of all your damages. An experienced attorney can help coordinate both claims to ensure you receive the maximum benefit from each coverage.

Frequently Asked Questions

What is the difference between MedPay and UM/UIM coverage?

MedPay covers medical expenses only, pays regardless of fault, and has relatively low limits. UM/UIM coverage provides broader compensation including medical bills, lost wages, and pain and suffering, but only applies when the at-fault driver is uninsured or underinsured.

Can I use both MedPay and UM/UIM coverage after an accident?

Yes. You can file a MedPay claim for immediate medical expenses and a UM/UIM claim for the full range of your damages. The two coverages serve different purposes and can work together to maximize your recovery.

Will using MedPay reduce my UM/UIM claim?

It depends on your policy. Some policies allow the insurer to offset MedPay payments against the UM/UIM recovery, while others treat them independently. Even with an offset, non-medical damages like lost wages and pain and suffering are generally unaffected.
