Why health insurance alone may not replace auto medical coverage after a car accident
Five coverage gaps your health plan can leave and how MedPay or PIP may help
Safety Behind the Wheel Foundation built this guide from National Highway Traffic Safety Administration (NHTSA) data, consumer guidance from the National Association of Insurance Commissioners (NAIC) and the Centers for Medicare & Medicaid Services (CMS), the auto insurance guides of the Texas, California, Washington and Michigan insurance regulators, a U.S. Supreme Court decision and published studies on the cost of injuries. Every source is listed at the end.
Two kinds of coverage with two different jobs
In 2024, crashes killed 39,254 people in the United States and injured about 2.42 million more [1]. For many families, one of the first worries after the ambulance ride is simple: who pays?
Most people assume their health plan will handle it, and it often pays a large share. But health insurance was built to pay for medical care for its own members. A collision can hurt passengers and people walking nearby, and it can leave workers unable to work.
Auto medical coverage has a different job. National insurance regulators describe medical payments coverage, often called MedPay, as covering treatment for the driver’s and passengers’ injuries [2]. Personal injury protection, or PIP, pays medical bills and can also pay lost wages and funeral costs [2]. In no fault states, your own insurer pays you for your injury losses no matter who caused the accident [3].
You do not have to choose one or the other. The useful question is where your health plan stops.
Gap one: deductibles, copays and coinsurance
Health plans share costs with you. A deductible is what you may owe each coverage period, usually a year, before your plan starts to pay [4]. A copay is a set fee for a service. Coinsurance is your percent share of a covered bill [4]. The out of pocket limit caps what you pay toward covered care in a year [4].
After a car accident, these costs tend to land all at once. And because the deductible runs by coverage period, a collision late in the year can mean paying a second one when the new year starts [4].
Research shows how real these costs are. A national study looked at privately insured adults treated for injuries from 2008 to 2018 [5]. They faced out of pocket costs of about $660 in the month of their injury [5]. People in high deductible plans paid about $1,703 more over the next 12 months than people in traditional plans [5]. About 13% of high deductible plan members faced costs that were catastrophic for their income, compared with 5% of all patients [5].
The money stress can last. A 2026 study linked trauma records with credit reports for patients hospitalized from 2019 to 2021 [6]. Eighteen months after injury, the share with medical debt in collections had risen by 5.2 percentage points [6]. Privately insured patients were among the hardest hit, while people on Medicare and Medicaid saw little change [6].
Depending on your state and policy, MedPay or PIP may pay part of what your health plan leaves behind, up to its limit. Ask your agent how your policy treats those leftover amounts.

Health plan cost terms and questions to ask
| Health plan term | What it means | Question to ask |
|---|---|---|
| Deductible | What you pay before the plan pays [4] | How much is left this year? |
| Copay | A set fee for a visit or service [4] | What is the copay for therapy? |
| Coinsurance | Your percent share of a bill [4] | What percent do I pay after the deductible? |
| Out of pocket limit | Your yearly cap on shared costs [4] | When does the cap reset? |
| Out of network care | Care from providers with no plan contract [4] | Is the nearest trauma center in network? |
Gap two: people in your car who are not on your plan
Your health plan protects you and the people enrolled with you. It does nothing for the coworker riding along, your child’s friend in the back seat or a grandparent on a different plan.
Those riders may have high deductibles of their own. Some may have no health insurance at all. A national study looked at adults ages 26 to 64 hospitalized for crash injuries from 2014 to 2017 [7]. The median hospital charge was $53,467 [7]. It estimated that 91.5% of uninsured patients were at risk of catastrophic health costs, and so were 10.1% of insured patients [7].
Auto medical coverage is often tied to the car rather than to one family’s health plan. In Texas, the state insurance department says PIP and MedPay pay medical bills for you and your passengers [8]. Texas MedPay can also pay if you are hurt riding in someone else’s car, or while walking or biking [8]. California’s guide says MedPay can pay for you or your passengers, no matter who is at fault [9]. Washington’s PIP covers the named insured, related household members, non family passengers and pedestrians hurt in the collision [10].
This has a safety side. A passenger who fears a large bill may put off a checkup. Coverage that pays early care removes one reason to wait. Our guide to crash symptoms that need medical care can help.
Gap three: lost pay and help at home
Health insurance pays for medical care. It does not pay you for the shifts you miss. It does not pay someone to drive your kids to school while you heal.
PIP often reaches these costs. Regulators describe PIP as paying lost wages and funeral costs, not only medical bills [2]. Texas PIP also pays lost wages and other nonmedical costs [8]. Washington’s basic PIP benefits are [10]:
- Up to $10,000 for medical and hospital costs for each injured person.
- Lost wages of up to $200 a week, with a $10,000 total.
- Up to $200 a week, with a $5,000 total, for household services you cannot do.
- Up to $2,000 in funeral costs.
Higher limits can be bought in Washington [10]. In Michigan, the medical part of PIP can be limited or dropped in some cases. But wage loss, survivor’s loss, replacement services and some funeral costs stay in the policy [11].
MedPay is different. Regulators describe it as paying to treat injuries, not as a source of lost pay [2]. Sick leave or disability benefits through work may also help.
Gap four: plan rules, limits and exclusions
Not every kind of health coverage pays for car accident injuries the same way. The plan’s own rules matter as much as the card in your wallet.
Some coverage leaves out services a serious collision can require. Michigan’s state guide notes that PIP pays for things Medicare often does not cover [11]. Examples include attendant care, rides to medical visits, vehicle changes and long term care [11].
Short term health plans need a close look. State regulators note that these plans do not have to offer the full set of essential health benefits [12]. They can also turn people away or charge more for preexisting conditions [12].
Some health plans limit or exclude auto injuries. In Michigan, a health plan can stand in for PIP medical only if it covers auto accident injuries without excluding or limiting them [13]. Before you count on any plan, check for limits like these.
Network rules can also shift costs. Care from providers outside your plan’s network can cost you more [4], and after an accident you may not get to choose who treats you.
Gap five: your health plan may ask to be repaid
Paying a bill is not always the end of the story. When another party is responsible for a collision, a plan that paid your bills may try to get that money back. This is often called subrogation or reimbursement.
Medicare works this way by law. When no fault or liability insurance is responsible, it pays first and Medicare pays second [14]. If Medicare pays a bill in the meantime, it treats that as a conditional payment and expects the money back once a settlement, judgment or award comes through [14].
Private plans can have similar terms. In a 2013 case, the U.S. Supreme Court looked at an employer health plan that paid $66,866 for a worker’s car accident injuries [15]. The worker’s lawyers recovered $110,000 from the other driver and his own insurer, and $44,000 of it went to legal fees [15]. The plan’s terms called for repayment from any money recovered, including money from the worker’s own insurer [15]. The Court held that in this kind of employer plan case, the plan’s written terms control [15].
The lesson for families is plain: a settlement may shrink once a health plan takes its share. Before you settle, ask each plan in writing what it says you owe, and ask a lawyer how the rules apply to you.
What state laws require: a national patchwork
As of October 2026, there is no single national rule for auto medical coverage. Each state decides whether it is built into the policy, must be offered or is simply available [8, 9, 10]. In no fault states, your own insurer pays your injury losses regardless of fault [3]. In other states, MedPay or PIP may be an option you can choose or reject [9, 10].
These four states show how much the rules differ.
Comparison compiled by Safety Behind the Wheel Foundation
Auto medical coverage rules in four states
| State | The rule | What stands out |
|---|---|---|
| Texas | Every policy includes PIP unless you reject it in writing [8] | MedPay also covers you as a passenger, walker or biker [8] |
| California | MedPay may be offered, and you can decline it. The lowest limit is $1,000 per person [9] | The state guide says health insurance usually pays for immediate care [9] |
| Washington | Insurers must offer PIP. To refuse it, you must reject it in writing [10] | Benefits include lost wages, household services and funeral costs [10] |
| Michigan | Drivers choose a PIP medical level, from unlimited down to an opt out for some Medicare enrollees [13] | A health plan must cover auto injuries to serve as backup [13] |
What Michigan’s choices teach every driver
Michigan offers the clearest view of the trade off. Drivers can choose unlimited PIP medical coverage, $500,000 or $250,000 [13]. People with qualifying health coverage can choose $250,000 with exclusions. Some Medicaid enrollees may choose $50,000, and people with Medicare Parts A and B may opt out of PIP medical [13].
The state sets conditions before health coverage can stand in. A plan qualifies only if it covers auto accident injuries without excluding or limiting them [13]. Its individual deductible must be under $6,579, the figure on the state page reviewed in October 2026 [13]. For some choices, household members must have other coverage, such as another auto policy or health insurance [13].
The duties continue after you choose. If you exclude or opt out of PIP medical and then lose qualifying health coverage, you must tell your auto insurer within 30 days. You must also get new health coverage or PIP medical in that time [11]. If you do not, you will not get PIP medical benefits after a crash [11]. And if you choose a lower limit, you may owe any bills above it yourself [11].
These rules make a good test anywhere: does your plan pay for crash injuries, and is everyone in your home covered? Safety Behind the Wheel Foundation urges every family to ask both questions.
How to check your coverage gaps
A careful review needs two documents and a quiet hour. Work in this order.
- Get your health plan’s summary of benefits and the full plan document. Find the deductible, coinsurance, out of pocket limit and network rules.
- Search the plan document for the words “motor vehicle,” “auto,” “subrogation” and “reimbursement.” Note any exclusions or repayment terms.
- Pull your auto policy’s declarations page. Look for MedPay or PIP, the limit per person and any deductible.
- List who rides in your car in a normal month: kids, carpool riders, older relatives and coworkers. Mark anyone with no health plan or a high deductible.
- Write down what one month off work would cost your household. Note any sick leave or disability benefits you have.
- Compare those gaps with what MedPay or PIP would pay. Ask your agent to price two or three limits.
- If your state lets you reject PIP or MedPay, decide only after steps 1 through 6.
- Repeat the review at each renewal, and whenever you change jobs or health plans.
Frequently asked questions
If I have good health insurance, do I still need MedPay or PIP?
It depends on your state, your plan and your household. Even strong health plans have deductibles and coinsurance, and they cover only enrolled members [4]. MedPay can pay medical bills for you and your passengers regardless of fault [9]. PIP may add lost wages and other costs [2]. Compare what your plan would leave unpaid with what auto coverage costs.
Will my health plan pay for my passengers?
Only if they are enrolled in your plan. Each passenger has their own health coverage, or none. State guides in Texas, California and Washington describe MedPay or PIP as paying for passengers [8, 9, 10]. Check your own policy to see who counts.
Can my health plan take money from my settlement?
It may, depending on the plan’s terms and your state’s rules. Medicare must be repaid from a settlement for conditional payments it made [14]. The U.S. Supreme Court has held that an employer plan’s written repayment terms control in that type of case [15]. Ask each plan for a written statement of what it claims before you settle.
Does health insurance pay for lost wages after a crash?
No. Health insurance pays for covered medical care. Lost pay may be covered by PIP in states that have it [2], by sick leave or disability benefits, or by a claim against an at fault driver. Washington’s basic PIP, for example, pays up to $200 a week in lost wages [10].
I’m on Medicare. Do I need auto medical coverage?
Medicare pays second when no fault or liability insurance is responsible [14]. Michigan’s guide notes that PIP can pay for some things Medicare often does not, such as attendant care [11]. In Michigan, people with Medicare Parts A and B may opt out of PIP medical, but household members need other coverage [13]. Ask your agent what your state allows.
Can I reject PIP or MedPay to save money?
In some states, yes. Texas and Washington require a written rejection [8, 10], and California lets you decline MedPay [9]. Before you sign, check your health plan’s deductible, who rides with you and how you would cover lost pay. A rejection form is easy to sign today and hard to undo after a crash.
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Safety Behind the Wheel Foundation recommends reviewing your health plan and auto medical coverage side by side before you need them. Health insurance is a key part of recovery after a crash, and it often pays a large share of the bills. But it was built to pay for medical care for its members. It can leave deductibles, passengers, lost pay, missing services and repayment claims for your family to sort out at the hardest possible time.
Auto medical coverage exists to fill some of those gaps quickly, often without waiting for anyone to decide fault. A short review of both policies now can show where your family is exposed, so you can choose with a clear head, not in a hospital waiting room.
