A practical guide to paying medical bills now—without surprises later
After a car wreck in Boise or anywhere in the Treasure Valley, medical bills start arriving long before your injury claim is finished. Two common ways people cover early treatment are MedPay (Medical Payments Coverage on an auto policy) and health insurance. The confusing part comes later: subrogation (repayment rights), liens, and how those reimbursements can affect your net recovery. This article breaks down what “Idaho MedPay vs health insurance subrogation” really means—so you can make informed decisions and protect your case strategy.
Start here: What are MedPay and subrogation?
MedPay is an optional auto insurance coverage that can pay for reasonable medical expenses related to a car accident (often for you and your passengers), regardless of fault—up to your chosen limit. It’s commonly used for ER visits, imaging, follow-ups, PT, deductibles, and copays.
Subrogation is the process where an insurer (or sometimes a benefits plan) seeks reimbursement from the at-fault party’s insurance or from your settlement for amounts it paid. In plain terms: if someone else caused the crash, payors may claim they should be paid back out of your recovery.
MedPay vs. Health Insurance: what’s different in real life?
| Category | MedPay (Auto Policy) | Health Insurance |
|---|---|---|
| Fault required? | No. Pays regardless of who caused the crash. | No. Pays per plan rules (networks, approvals, etc.). |
| Speed of payment | Often fast if bills are coded correctly and submitted. | Can be fast, but depends on network status and claim processing. |
| What it helps most with | Deductibles, copays, early treatment costs, cash-flow relief. | Broad medical coverage and negotiated rates. |
| Subrogation / repayment risk | May seek reimbursement depending on policy language and circumstances. | Often seeks reimbursement (especially ERISA plans, Medicare/Medicaid, workers’ comp). |
| Provider billing behavior | Some providers prefer health insurance first; others will bill MedPay if available. | Network contracts can limit what providers can charge. |
One key Idaho-specific point: Idaho’s statute on collateral sources limits “double recoveries” and has specific exceptions for benefits that are recoverable under subrogation rights created by Idaho law or by contract. That’s part of why subrogation analysis is so fact-specific: the “who gets paid back” question often depends on the plan/policy language and the type of payor.
Where people get blindsided: liens and “bill insurance first” rules
Many injured people assume a provider can simply “wait and take it from the settlement.” Idaho law has evolved on this issue. In DeKlotz v. NS Support, LLC (opinion filed August 19, 2025), the Idaho Supreme Court held that filing a medical lien can be an “extraordinary collection action” under the Idaho Patient Act, meaning a provider must comply with the Act’s requirements (including timely submitting charges to a patient’s insurance) before recording a lien in that context.
What that means for Boise-area crash victims: if you have health insurance, it may be important to ensure providers properly bill insurance rather than attempting to bypass insurance and attach a lien to your injury claim. The details matter—and they can materially affect how much of your recovery you keep.
How this plays out in a typical Boise crash claim
Here’s a common pattern in Idaho car accident cases:
1) Treatment starts immediately (ER/urgent care, imaging, orthopedics, PT). Bills start stacking up while liability is still being investigated.
2) MedPay can reduce immediate out-of-pocket pressure by covering deductibles, copays, or early bills—helpful for families and working professionals who can’t float the costs.
3) Health insurance pricing can control the “sticker shock” because negotiated rates may be far lower than self-pay charges.
4) Subrogation claims arrive later (sometimes near settlement). This is where careful documentation matters: itemized payments, plan language, and verification of who paid what and when.
If Medicaid is involved, third-party liability/subrogation rules are especially strict, and repayment obligations can apply when a participant recovers funds from a third party.
Quick “Did you know?” facts
Idaho has a “collateral source” statute.
In many injury cases, post-verdict adjustments can account for certain payments from collateral sources—subject to statutory exceptions, including for subrogation-recoverable benefits.

Medical liens aren’t a free-for-all.
Idaho’s Supreme Court addressed when lien filing collides with the Idaho Patient Act’s protections and billing requirements (case filed from an August 2021 lien; opinion issued August 19, 2025).

Liability coverage minimums matter.
Idaho requires minimum bodily injury liability limits (commonly expressed as 25/50), which can influence settlement ceilings and how subrogation and liens impact your net recovery.

Local angle: Boise, Meridian, and the construction community
In Boise and the surrounding Treasure Valley, many injured drivers are also working professionals—project managers, contractors, and business owners—who can’t afford long interruptions or billing chaos. If you’re juggling jobsite demands and recovery:
Actionable steps that protect both health and claim value:
Keep a single “payments and letters” folder (digital works great on iPhone): Explanation of Benefits (EOBs), MedPay checks, and any subrogation letters.
Confirm how each provider is billing (health insurance first vs. MedPay vs. self-pay) before you rack up weeks of treatment.
Don’t ignore lien notices. Timing and statutory requirements can matter, and early legal review can prevent avoidable deductions later.

FAQ: Idaho MedPay and health insurance subrogation
Should I use MedPay or health insurance first after a Boise car accident?
Often, health insurance is used for the main billing (to access negotiated rates), while MedPay is used to cover deductibles, copays, or specific bills. The best approach depends on your providers, your policy language, and whether subrogation or liens are likely.
Will I have to pay MedPay back from my settlement?
Possibly. Some auto policies assert reimbursement rights in certain situations. The answer depends on the exact policy terms, who was at fault, and how your recovery is structured. An attorney can review your declarations page and policy language to confirm.
What if a medical provider files a lien instead of billing my insurance?
Idaho’s Supreme Court has addressed how medical lien filing interacts with the Idaho Patient Act’s billing requirements. If you had health insurance and it wasn’t billed before a lien was recorded, there may be legal issues worth evaluating quickly.
Does Idaho law allow “double recovery” for medical bills?
Idaho has a statute that limits certain double recoveries from collateral sources, with important exceptions (including benefits that are recoverable under subrogation rights created by Idaho law or contract). That’s why it’s crucial to identify who has valid reimbursement rights early.
What if Medicaid paid some of my crash-related treatment?
Medicaid has third-party liability and subrogation rules that can require repayment from third-party recoveries. Handling Medicaid correctly is time-sensitive and documentation-heavy, so it’s smart to get help coordinating it.
