No-fault insurance pays your medical bills and lost wages after a car accident, regardless of who caused it

No-fault insurance is a system where your own insurance company pays for your medical expenses and a portion of lost income after a car accident — even if the other driver caused the crash. You do not have to prove the other person was at fault, and the other driver's insurance does not have to agree to pay. Instead, you file a claim with your own insurer, which processes it faster than the traditional fault-based system.

This system exists in twelve states plus Puerto Rico and the District of Columbia. The states are Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah. If you live in one of these places, your auto insurance policy includes no-fault coverage by law — you cannot opt out of it, though you can choose how much coverage to buy.

The trade-off is that no-fault insurance limits your right to sue the other driver for pain and suffering. In most no-fault states, you can only sue if your injuries meet a certain threshold — either a dollar amount in medical bills or a description of the injury itself, such as permanent scarring or broken bones. This threshold varies by state.

Key Takeaways

  • No-fault insurance pays your medical bills and lost wages from your own policy after any accident, regardless of fault.
  • Twelve states and three U.S. territories require no-fault coverage; in these places it is mandatory and cannot be removed from your policy.
  • You can only sue the other driver for pain and suffering if your injuries exceed your state's threshold, which is either a dollar amount or a specific injury type.
  • Claims are filed with your own insurer and typically process faster than fault-based claims, but the amount paid is capped by your policy limits.

What no-fault insurance actually covers

No-fault coverage pays for reasonable and necessary medical treatment related to the accident. This includes emergency room visits, hospital stays, surgery, physical therapy, prescription medications, and mental health treatment. The coverage also pays for diagnostic tests, imaging, and follow-up care. Some states allow coverage for treatment from chiropractors and acupuncturists if they are licensed in that state.

The second major component is lost wage replacement, which pays a portion of your income if the accident prevents you from working. The replacement rate is typically 85 percent of your lost wages, up to a weekly maximum that varies by state. In New York, for example, the maximum is currently around $2,000 per week, but this amount changes annually. In Michigan, there is no weekly cap on wage replacement if you have unlimited coverage, though most policies have limits.

No-fault coverage also pays for reasonable charges for services you cannot perform yourself because of the accident — such as housekeeping, childcare, or yard work. The amount and duration of this coverage vary by state and by your specific policy.

What no-fault insurance does not cover is pain and suffering, emotional distress, or punitive damages. Those claims require a lawsuit, and you can only pursue them if your injuries meet your state's threshold.

How the threshold for suing works

Most no-fault states use one of two threshold systems: a monetary threshold or a verbal threshold. A monetary threshold means you can sue for pain and suffering only if your medical bills exceed a certain amount. In New Jersey, that amount is $20,000. In New York, it is $50,000. In Florida, it is $10,000. These amounts do not adjust for inflation in most states, so they have not changed in years.

A verbal threshold describes the type of injury that allows a lawsuit. Michigan uses this approach: you can sue if you have suffered a "serious impairment of body function" or "permanent serious disfigurement." Massachusetts uses similar language. These thresholds are interpreted by courts, so what qualifies can shift over time and vary between judges.

Some states, like Pennsylvania, let you choose between thresholds when you buy your policy. You can select a lower threshold (which costs more in premiums) or a higher one (which costs less). The choice you make at purchase is binding for the policy period.

How to file a no-fault claim

After an accident, notify your insurance company as soon as reasonably possible. Most insurers have a 24-hour claims line. You will need to provide your policy number, the date and location of the accident, and a description of what happened. You do not need to admit fault or provide a detailed statement at this stage.

Your insurer will assign a claims adjuster, who will contact you to gather more information. Bring your medical records, receipts for treatment, proof of lost wages (such as pay stubs or a letter from your employer), and any receipts for services you paid for out of pocket. Keep copies of everything you submit.

The insurer will review your claim and either approve it, request more information, or deny it. If approved, they will pay the medical provider directly or reimburse you, depending on your state's rules and your policy. Wage replacement is typically paid to you directly. The entire process usually takes two to four weeks for straightforward claims, though complex cases can take longer.

Differences between no-fault and fault-based insurance states

In a fault-based state, the driver who caused the accident is responsible for paying the other person's medical bills and damages. You file a claim with the at-fault driver's insurance company, and that company decides whether to pay. If they deny the claim or offer too little, you can sue. This process is slower but allows you to recover pain and suffering without meeting a threshold.

In a no-fault state, you always file with your own insurance first, regardless of who caused the accident. Your insurer pays your bills up to your policy limits. You can still sue the other driver, but only if your injuries meet the threshold. This system is faster for basic medical bills but more restrictive for larger claims.

No-fault states also typically have stacking rules, which determine whether you can combine coverage from multiple policies. For example, if you are a passenger in someone else's car, you may be able to stack your own policy's no-fault coverage with the vehicle owner's coverage, increasing the total amount available to you. Stacking rules vary significantly by state and policy.

What happens if you disagree with the insurer's decision

If your insurer denies your claim or pays less than you believe you are owed, you have the right to dispute it. The first step is to request a written explanation of the denial. Review it carefully and gather any additional evidence that supports your claim — such as medical records the adjuster may have missed or testimony from your doctor.

Many no-fault states require appraisal or arbitration before you can sue. In appraisal, an independent medical professional reviews the dispute and makes a binding decision on whether the treatment was reasonable and necessary. In arbitration, a neutral third party hears both sides and decides the case. The rules and costs for these processes vary by state.

If appraisal or arbitration does not resolve the dispute, you can file a lawsuit against your own insurer for breach of contract. You will need an attorney for this, and you may be able to recover attorney fees if you win. Some states allow you to sue for bad faith if the insurer acted unreasonably in denying or delaying your claim.

How much coverage you should buy

No-fault insurance is mandatory in no-fault states, but the amount of coverage you buy is your choice. Most states set a minimum — for example, New York requires at least $50,000 in no-fault coverage. However, medical bills from a serious accident can easily exceed this amount. Physical therapy, surgery, and long-term care can cost hundreds of thousands of dollars.

If your medical bills exceed your policy limit, you cannot recover the excess through no-fault insurance. You can only pursue it through a lawsuit if your injuries meet the threshold — and even then, you would be suing for pain and suffering, not for the unpaid medical bills themselves. For this reason, many financial advisors recommend buying higher limits than the state minimum, especially if you have significant assets to protect.

Wage replacement limits also matter. If you are self-employed or earn a high income, the weekly maximum may not fully replace your lost earnings. Review your policy to understand what you would actually receive if you were unable to work for several months.

Frequently Asked Questions

Can I sue the other driver in a no-fault state?

Yes, but only if your injuries meet your state's threshold. If you have medical bills over the dollar threshold or an injury that meets the verbal threshold (such as permanent scarring), you can sue for pain and suffering. If your injuries do not meet the threshold, you cannot sue, even if the other driver was clearly at fault.

What if I was partially at fault for the accident?

No-fault insurance pays your bills regardless of fault, so your own percentage of fault does not affect your no-fault claim. However, if you later sue the other driver and your state uses comparative negligence, your recovery may be reduced by your percentage of fault.

Does no-fault insurance cover damage to my car?

No. No-fault insurance covers only medical bills and lost wages. Damage to your vehicle is covered by collision insurance (if you have it) or the other driver's property damage liability insurance. These are separate coverages from no-fault.

What if the other driver does not have insurance?

Your no-fault coverage still pays your medical bills and lost wages. If you want to recover for pain and suffering and your injuries meet the threshold, you can sue the uninsured driver directly — though collecting a judgment from someone without insurance is often difficult.

Can I choose not to have no-fault insurance?

No, not in a no-fault state. It is mandatory and included in every auto policy. You can choose how much coverage to buy, but you cannot remove it entirely. Some states allow you to select a higher threshold (which lowers your premium) in exchange for accepting more restrictions on suing.
