We interviewed two subject matter experts, personal injury attorneys Patrick Hinrichs, Esq. and Dylan Kriegshauser, Esq. of The Bruning Law Firm, to give you the best possible answers on who pays medical bills after a Missouri car accident. Patrick has handled injury claims since 2010; Dylan has spent his entire career representing injury victims.
A NOTE BEFORE YOU READ
No two cases are the same, and while we can give you a general answer, we cannot give you yours without knowing your situation. What follows is a strong start on understanding your claim, but it is no replacement for working directly with an attorney who has reviewed your specific case. If at any point you would rather just talk to someone, you are welcome to call us at (314) 735-8100. No pressure, and it costs nothing to find out where you stand.
Let's be honest about why you are here.
- You are in pain and deciding whether to go to the hospital.
- You are just back from the hospital and worried about what this whole ordeal is going to "cost you."
- The stack of medical bills on your counter keeps growing, and so does the dread.
Someone else caused this, and every one of those bills has your name on it.
If that is you, this page was written for you. The question underneath all of it is who pays medical bills after a car accident, more specifically when you are not at fault. For the time being, yes, you are the party responsible for your medical bills. The at-fault driver's insurer pays once, at the end, when your case settles. So it is important for you to understand exactly how fault is determined and when you should get an attorney involved in your case.
For most people, a serious crash is a once-in-a-lifetime event, but for Patrick and Dylan it is the work of every day, and an adjuster's early offer works best on someone still carrying unanswered questions. You have questions, and you are in the right place to get them answered before you sign anything.
Who Pays Your Medical Bills After a Car Accident in Missouri?
If you were not at fault, you still pay your medical bills first, through your own health insurance and your own auto policy. The at-fault driver's insurer pays once, at the end, when your case settles. Fault decides who is ultimately responsible, but it does not decide who pays the bill that came this week.
The money for this week's bill can come from five different places, depending on the coverage you have:
- Your health insurance
- Medical payments coverage (MedPay) on your own auto policy
- The at-fault driver's liability coverage
- Your own uninsured motorist coverage, if the other driver carried no insurance
- Sometimes, a provider willing to wait for your settlement
Each of these comes into play at a different point in your claim, so we will walk through them one at a time in the order you are likely to meet them. The ending is the same in every case: the at-fault driver's insurer settles the account, and some of what paid early takes a share back. Missouri car accident attorney Patrick Hinrichs of The Bruning Law Firm describes the demand many injured people get from their own health insurer after it covers crash treatment:
"You were in a crash, we made payments, you owe us money."
PATRICK HINRICHS, THE BRUNING LAW FIRM
The coverage that ultimately pays comes from Missouri's financial responsibility law, which defines the liability policy every driver must carry (RSMo § 303.190).
How Fault Is Assigned in a Missouri Car Accident Claim
Nobody decides fault at the scene of a Missouri crash, and even the police report is one piece of evidence rather than a final ruling. The at-fault driver's insurer makes its own opening call on liability, you are free to disagree with it, and if the two sides never agree, a jury decides. As Patrick puts it: "The adjusters don't determine the law in Missouri. The courts determine the law."
Missouri uses what is called pure comparative fault, a rule the Missouri Supreme Court adopted in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983). Every driver involved is assigned a percentage of the blame, and your recovery shrinks by your share. Say a case is worth $40,000, and the insurer successfully argues you were 20 percent at fault for following too closely. The recovery becomes $32,000. Partial fault reduces what you collect; it does not bar you from recovering, even when your share is large.
Those percentages sound like they would be calculated somewhere official, but in practice they are argued over like everything else in a claim. St. Louis personal injury attorney Dylan Kriegshauser, partner at The Bruning Law Firm, described a case from his own desk: his client was driving straight down a four-lane road when another driver ran a stop sign from a side street. Clean liability, on its face. The insurer's position was that his client should have seen the other car coming and swerved, and that failing to swerve made the crash partly his client's fault. That argument does not have to win outright. Every percentage point it earns is money off the claim.
Both attorneys raised the same caution here: you may not be the best judge of where fault sits in your own crash, and that has nothing to do with intelligence. You saw the crash from one seat, you do not know what the other driver is telling their insurer, and most of us are wired to get along, so we soften our own account and accept blame on instinct, just to be reasonable. The opposite error is just as common: complete certainty that the other driver is 100 percent at fault, with no idea what arguments are already being built on the other side. Being an honest, careful person feels like it should settle the question, but honesty is not evidence, and it does not move a liability decision. Dylan's advice for the gap between how sure you feel and what you can prove:
"You can't afford to be wrong about this. You've only got one bite of the apple."

Why You Should Keep Every Medical Bill in One Place
Start a folder today, whether that is a real folder on the kitchen counter or a photo album on your phone, whichever you will keep using. Every medical bill goes in it the day it arrives: the hospital, the ambulance, radiology, physical therapy, the pharmacy receipt, and every letter your health insurer sends about the crash. Date each one as it arrives, because you will forget things over the months a claim takes, and the folder will hold what memory drops.
That folder becomes the evidence of what this crash has cost you, because a claim is proven dollar by dollar through the bills themselves, and an insurer's offer only accounts for what it can see. Early offers usually arrive before anyone knows what your treatment will cost, which is why Patrick treats them as a warning sign:
"Anytime somebody offers you money on a first phone call, that should be a red flag."
PATRICK HINRICHS, THE BRUNING LAW FIRM
When an offer shows up before the folder has even filled, it was priced before anyone counted your damages.
If you hire an attorney, the folder rides along. Dylan tells clients the firm handles the gathering: "You don't need to worry about getting your medical bills, or your police report, or contacting anyone." The folder still matters, because it is the fastest way to make sure nothing gets missed. A bill that never makes it into the claim gets paid by you instead, and a crash someone else caused should not end with you in medical debt.
Your Health Insurance
Use your health insurance for every crash-related visit, starting with the emergency room. Some people hesitate because it feels like paying for the other driver's mistake, but using it is exactly the right move. Your health plan pays at rates it has already negotiated with the hospital, it keeps your account out of collections while the claim moves, and every payment it makes is documented for the settlement. The at-fault driver's insurer will not step in this month.
You already saw the catch in Patrick's words above. A health plan that pays for crash treatment may claim a share of your settlement at the end. Whether it can, and how much, depends on what kind of plan issued your card, and you cannot tell by looking at the card. Sorting that out is part of what an attorney does at settlement, because the difference between what a plan demands and what it accepts is real money.
In the St. Louis region, using health insurance runs into a second problem. Getting an appointment can take months. Hospital systems have bought up most of the primary care and specialty clinics, and many of their doctors are slow to see crash patients. A primary care office may offer you a date six weeks out, and Dylan has heard specialists quote far worse:
"They might tell you, yeah, you can come see me, I have openings January 13th of 2027."
DYLAN KRIEGSHAUSER, THE BRUNING LAW FIRM
Part of the firm's daily work is getting clients in front of doctors who will evaluate a crash injury and put it in the notes.
MedPay on Your Own Auto Policy
MedPay is short for medical payments coverage, an optional line on your own auto policy that pays medical bills for you and your passengers after a crash, no matter who caused it. Many Missouri drivers carry it and do not know it. Find your declarations page, the summary sheet that came with your policy, and look for the words "medical payments." If they are there, this coverage can start paying early bills while the larger claim moves. We wrote a full guide to MedPay versus liability insurance if you want the details.
The At-Fault Driver’s Liability Coverage
This is the coverage everyone expects to pay, and it does, once, at the end. The at-fault driver's insurer has no obligation to pay your bills as they arrive. It pays when you sign a settlement release or when a jury enters a verdict, and the number is built from the record you kept: the bills, the imaging, the treatment notes, the work you missed.
That number cannot be known early, and Dylan says so to every client who asks:
"I don't know what your case is worth right now, and any lawyer that does tell you they know what your case is worth is lying to you."
DYLAN KRIEGSHAUSER, THE BRUNING LAW FIRM
The value of your claim depends on the full extent of your injuries, which takes months of treatment to know, and on how much insurance the at-fault driver carried. Both of those answers take time to arrive, and the early offer tends to land before either one does.
Your Uninsured Motorist Coverage
Missouri requires every auto policy sold in the state to include uninsured motorist coverage (RSMo § 379.203). If the driver who hit you carried no insurance, your own policy stands in for theirs, and your medical bills become part of a claim against your own insurer. Most hit-and-run crashes work the same way when the driver is never found. Your insurer handles that claim the way any insurer does, so the same care with statements, paperwork, and early offers applies even though the company is your own.
Providers Who Wait for Your Settlement
Some bills get paid by nobody until the case ends. Missouri law gives hospitals and clinics a lien process (RSMo § 430.225), a formal claim against your future settlement instead of a bill in your mailbox today. Other providers treat and wait to be paid out of the settlement. Missouri's lien statute is what allows that arrangement, often documented in a letter of protection, and your attorney puts it to work for you. These arrangements keep treatment moving when the other ways of paying have run out.
They are also contracts, with real consequences for what you take home. A lien filed against your settlement and a provider's promise to wait are both documents an attorney should read before they exist. This is the corner of the medical-bill map with the most moving parts, and the corner where a general article helps least. If your situation lives here, bring it to a professional.
What Happens if You Take the Early Offer
Patrick has watched this play run for years. The adjuster accepts liability, sympathizes, and makes it easy: "Send me your ER bill, we'll take care of it. And I'll throw a little cherry on top. I'll give you 1500 bucks for everything you've been through."
The check feels like relief, and cashing it can end your claim. Patrick has met the aftermath more than once: a client in real pain, an early check already cashed, and nothing left to do.
"The second you sign a settlement release with an insurance company, your case is over."
PATRICK HINRICHS, THE BRUNING LAW FIRM
A signed release closes the claim permanently, no matter what a doctor finds the following month. Pain that arrives late is normal after a crash, since adrenaline can mask an injury for two or three days, which means an offer that arrives before your diagnosis was priced without it.
Some adjusters attach a deadline and call it a one-time offer. Patrick has heard that speech many times, and his verdict on it is short: "It's an empty threat." You are allowed to hang up, see a doctor, and let the record answer for you. Patrick's bottom line for anyone who was not at fault: "You get to dictate the conversation, not the insurance adjuster."
When to Get an Attorney Involved
Dylan has a working test from years of first calls: "When they don't have a clear plan of exactly what to do, which most people don't, that's how I know they need an attorney to guide them through the process." If you know your next three steps and what each one costs you later, you may be fine on your own. Most people are somewhere else entirely, and the cost of guessing wrong does not announce itself until the case is over.
The timing question is simpler, because calling early costs the same as calling late, and an early call catches evidence before it fades and witnesses before they move. Dylan again: "There's really no benefit to you, the price is the same, the output is significantly better the sooner you call."
And hiring a firm is a decision this firm will sometimes talk you out of, because when taking a fee would leave the client worse off, the answer is no.
"We've turned away plenty of cases where we say, you know what, we think you're better off handling this on your own... It just doesn't make sense. It wouldn't be fair to you as the client."

FAQ: Medical Bills After a Missouri Car Accident
Who pays medical bills after a car accident when you are not at fault?
For the time being, you do, through your own health insurance and your own auto coverage. The at-fault driver's insurer pays one time, at the end, when your case settles or a jury decides it. Fault determines who is ultimately responsible for the crash, but it does not change who the hospital bills while the claim is open.
Do I have to pay my hospital bill before my settlement?
Route every bill through your health insurance first. Some remaining balances can wait for your settlement under a lien or a letter of protection, and some cannot. Ignoring a bill is the one option that reliably goes badly, because billing offices send unpaid accounts to collections on their own schedule. If a balance is growing and your settlement is months away, an attorney can usually address that with the provider directly.
Can a hospital send my bill to collections while my claim is still open?
Yes. An open injury claim does not pause a hospital's billing department. This is the reason to run bills through your health insurance now and keep every statement in one folder. An attorney can contact the provider, explain that a claim is pending, and arrange for the account to wait. The sooner that call happens, the more options exist.
What happens to my medical bills if I settle before I finish treatment?
The release ends the claim, and treatment you need after signing is yours to pay for. Patrick sees the hard version of this regularly: "You settle, and you have all these problems, and now you have to go get treatment for them, and now you're paying for all that treatment out of pocket." Finish treatment first, or know exactly what you are giving up before you sign.
