Add-on no-fault: PIP benefits without a limit on suing

In an add-on system, your own auto policy pays a set of first-party benefits, usually called personal injury protection (PIP), no matter who caused the crash, and the law places no extra hurdle in front of an injury lawsuit against the at-fault driver. That is the difference from a threshold no-fault state, where you may sue only after your injuries pass a legal bar. Add-on PIP is a cash-flow tool: it pays early medical bills and lost wages while the liability claim is still being argued.

Sources do not agree on which states belong in the add-on group, and the details behind the label (who must buy PIP, how it can be waived, who gets repaid) differ sharply. This article walks through a hypothetical claim and uses the statutes of Texas, Maryland, Oregon and Washington to show how much the details vary. Figures are as of November 2026 from the sources named.

What "add-on" means, and how it differs from the other systems

Every state's rules sit somewhere on a line between two ideas. At one end is the traditional tort system: the at-fault driver's liability insurance pays for the injured person's losses, and the injured person proves fault to collect. At the other end is the no-fault idea: each person's own insurer pays their medical bills and lost income, and in exchange the right to sue is restricted.

Add-on states keep the tort system intact and bolt first-party benefits onto it. The Insurance Information Institute (III) describes the add-on design as first-party benefits added to a tort system with no lawsuit restrictions, and notes that in such states the first-party coverage may not be mandatory (III background on no-fault). The same III page counts twelve states, plus Puerto Rico, that restrict lawsuits: five with a verbal threshold (Florida, Michigan, New Jersey, New York, Pennsylvania) and seven with a dollar threshold (Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota, Utah). Three more states (New Jersey, Pennsylvania and Kentucky) let drivers choose a restricted-lawsuit option, which is the choice no-fault model.

The practical test is a single question: after you collect PIP, can you still file an ordinary injury claim against the other driver without proving that your injury is "serious" or that your bills passed a dollar figure? If yes, the state is functioning as an add-on state, whatever name a chart gives it. The glossary entries for add-on state and no-fault insurance give the short definitions.

Why the lists of add-on states disagree

Ask three sources which states are add-on and you may get three answers. The III page above defines the add-on design but does not publish a list of add-on states, and it notes that Pennsylvania was an add-on state before 1990, when it moved to a choice system. Trade publications and consumer sites publish their own lists, and they differ on whether to include states where PIP is optional, states that require only a small medical payments coverage, and the District of Columbia, which III describes as neither true no-fault nor add-on.

Two questions explain most of the disagreement. First, is first-party coverage mandatory, offered, or only available? Oregon requires PIP in private passenger policies, while Texas, Washington and Maryland require that it be provided or offered and let the buyer reject or waive it in writing. Some states sometimes called add-on only require insurers to offer a small medical payments coverage, which is not PIP. Second, does the state restrict lawsuits anywhere? If it does, it belongs in the threshold or choice group.

Rather than rely on any list, check your own state with the state car insurance requirements lookup tool and your state insurance department's consumer pages.

A hypothetical claim, step by step

Say you are rear-ended in a state with add-on PIP. The other driver is clearly at fault. You have a broken wrist and miss five weeks of work. These numbers are made up for illustration and are not market data: $31,000 in medical bills, $6,500 in lost wages, and a policy with PIP limits of $10,000.

1. Report the crash to your own insurer and open a PIP claim. The claim does not wait for a fault decision. Your insurer pays covered medical bills and a share of the lost wages, up to the $10,000 limit, as bills arrive.
2. Use health insurance for what PIP will not cover. The remaining $21,000 in medical bills goes to your health plan, if you have one, subject to its rules about auto-accident claims and its own right to be repaid.
3. Open a liability claim against the at-fault driver's insurer. In an add-on state you do not have to show a threshold injury. You claim your economic losses (bills, wages) and, because the tort system is intact, damages for pain and suffering.
4. Account for what has already been paid. This is the step where state law changes the outcome. Depending on the state, the PIP insurer may be repaid from your liability settlement, may be repaid by the other driver's insurer, or may have no repayment right at all. The next section covers the three models.
5. Settle or sue. The at-fault driver's liability limit caps what that insurer can pay, which is why uninsured motorist coverage still matters in a state with generous PIP.

Add-on PIP is valuable even for someone who intends to sue, because it puts money to work in weeks rather than months. The same $10,000 can be a pure advance or a loan against your settlement, depending on the state.

Offsets and repayment: three different answers

When your PIP insurer pays benefits, who bears the cost in the end? The statutes of three add-on states answer differently.

Maryland's rule is spelled out in the Maryland insurance statute on PIP payments, which also says the benefits are payable without regard to fault or to any collateral source of medical, hospital or wage continuation benefits. Texas says the same about fault and collateral sources, and sets out the narrow subrogation exception in Texas Insurance Code section 1952.155.

Oregon's two sections are more intricate. Under ORS 742.534, a motor vehicle liability insurer whose insured is or would be legally liable for the injury must reimburse the insurer that furnished PIP (or a health insurer that paid) when that insurer asks, unless it elected recovery by lien. The reimbursement, together with what the liability insurer paid the injured person, cannot exceed the liability policy's limits, and disputes between insurers go to arbitration. ORS 742.544 then protects the injured person: an insurer cannot receive reimbursement or subrogation for PIP or health benefits from the injured person's recovery in a damages action except to the extent that the person first receives full compensation, and then only from the excess. The statute sets rebuttable presumptions about when full compensation has been received, so a short read of the text is not a substitute for the full section.

A repayment right changes how much of a limited liability policy is left for you once the insurers have settled their accounts. If a PIP insurer or your health insurer sends a notice claiming repayment, ask for the statute or policy provision it relies on, and have an attorney licensed in your state read any settlement release that says "all claims" before you sign.

For a deeper look at how an insurer's recovery against an at-fault driver works in general, see subrogation: when your insurer sues the at-fault driver.

Written rejection and waiver rules

Because add-on PIP is often optional, the law surrounds the choice with paperwork. The rules vary, and a signature on a renewal form can matter years later.

Texas. Under Texas Insurance Code section 1952.152, an insurer may not issue an auto liability policy unless PIP is provided in or alongside the policy, but the requirement does not apply if any insured named in the policy rejects the coverage in writing. The statute adds that the insurer need not offer PIP again on a renewal or reinstated policy if the named insured rejected it on that policy or on a policy from the same or an affiliated insurer, unless the named insured requests the coverage in writing. A rejection in one year can therefore quietly continue.

Washington. RCW 48.22.085 requires that PIP be offered as optional coverage on new and renewal policies. A named insured may reject it in writing, and the rejection is valid and binding as to all levels of coverage and on everyone who might have been insured under it. The insurer need not include PIP in a supplemental, renewal or replacement policy unless a named insured later asks for it in writing.

Maryland. Maryland flips the default. Unless waived, the insurer must provide the PIP benefits in section 19-505, and a waiver must be an affirmative written one by the first named insured. Under section 19-506, the waiver is not effective unless the insurer first gave written notice of the nature, extent and cost of the coverage, and it must be on a form the Insurance Commissioner requires, with explanations in 10-point boldface. The form must also say that an insurer may not refuse to underwrite a person because the person declines to waive. The waiver is binding on each named insured, each listed driver and each household family member who is at least 16, although a person caught by the waiver may still recover under another policy of which they are the first named insured and under which no waiver is in effect. A separate section, 19-506.1, allows a rejection of PIP on certain minimum-limit policies written through the Maryland Automobile Insurance Fund or after a cancellation by a prior insurer.

Oregon. ORS 742.520 takes the opposite view. The statute says a policy covering a private passenger vehicle "shall provide" PIP benefits; it is written as a requirement, not an offer.

Before you sign any PIP rejection or waiver, run through this checklist:

• Who is bound? In Maryland, the first named insured's waiver reaches household members.
• Did the insurer tell you the cost? Weigh the premium saved against the benefits given up with the numbers in front of you.
• Does the rejection continue into renewals? In Texas and Washington it can.
• Is your health coverage solid, with a deductible you can afford? PIP can pay first-dollar bills that a high-deductible health plan would not.

What PIP pays, and how little or how much it can be

The size of the benefit is the other major variable. In add-on states it is often modest compared with threshold states, though not always.

These are statutory minimums or maximum required amounts, legislatures change them, and the declarations page of your own policy controls the limit you bought. The Personal injury protection (PIP) explained guide covers the general benefit categories, and PIP benefits explained: medical bills, lost wages and services looks at each one in more detail.

Texas also sets deadlines on the insurer. Under section 1952.156, PIP benefits are to be paid periodically as claims arise, not later than the 30th day after the insurer receives satisfactory proof of a claim, and a policy may set a period of not less than six months after the accident for presenting the original proof of loss. If the insurer fails to pay when due, section 1952.157 lets the person entitled to benefits sue in contract and recover reasonable attorney's fees, a 12 percent penalty and interest.

Health insurance, medical payments coverage and PIP together

Three coverages can respond to the same hospital bill, and the order matters.

In Texas and Maryland, the statutes say PIP benefits are payable without regard to any collateral source of medical, hospital or wage continuation benefits. In Texas that is the end of the story. In Maryland there is a further option: if you have both PIP and a collateral source, the insurers may coordinate the policies to avoid duplicating benefits, but only with appropriate premium reductions approved by the Commissioner, and the named insured can choose which policy is primary or reject coordination altogether (section 19-507). Choosing a primary policy is a decision worth making deliberately, because it determines which insurer's deductibles and network rules apply first.

In Oregon, the interplay between PIP and health insurance is built into the reimbursement sections: a health insurer that paid may be repaid by the liability insurer under ORS 742.534, and ORS 742.544 limits any attempt to take repayment from the injured person's own recovery.

A practical order of operations after a crash in an add-on state:

1. Tell your auto insurer about the injury at once and ask whether PIP is on your policy and what the limit is.
2. Give medical providers your auto claim number and your health insurance card, and ask your health plan how it treats auto-accident claims.
3. Keep a ledger of every bill, who paid it and when. You will need it for the liability claim and for any repayment dispute.
4. Read MedPay or health insurance: who pays first after a crash and Billed vs paid medical bills: collateral source rule and LOPs before you settle, because the amount a provider accepts can differ from the amount billed.

How the add-on design affects premiums

The effect of add-on PIP on price is a tradeoff, not a fixed discount or surcharge, and no honest single number applies to every state.

Add-on PIP adds a coverage that every insured buys (where it is mandatory) or most do (where it is optional), so it adds premium. What it does not do is remove the cost of liability claims, because the right to sue stays intact. III's discussion of no-fault experience notes that weak no-fault laws, meaning low thresholds and low PIP amounts, tended to see faster cost increases than verbal-threshold states because many minor-injury cases still went to court. An add-on design has no threshold at all, so it sits at the far end of that spectrum: the first-party layer adds cost without trimming the tort layer.

That does not mean add-on states are always expensive. Rates also depend on territory, claim frequency, repair costs, uninsured-driver rates and minimum limits, and a fair comparison between systems has to hold those constant. See Do no-fault states really cost more? Comparing premiums by system for how premium levels compare.

One consumer protection is worth knowing. Maryland's section 19-507(c) says an insurer that issues a policy with PIP may not increase the premium on that policy because of a claim or payment under that coverage, and must tell the policyholder so in writing when the policy is issued. Most states do not have an equivalent rule, so in other places ask your insurer how a PIP claim is treated at renewal.

Common questions

If I take PIP benefits, have I given up the right to sue?

Not in an add-on state. That is the defining feature of the system. The right to sue is restricted in threshold states, in choice states for those who selected the limited option, and nowhere else. Check your state's rules, because a policy sold in a choice state may have a limited-lawsuit option built in.

Is PIP the same as medical payments coverage?

They are cousins. Both pay your own medical expenses regardless of fault. PIP usually adds lost income and essential services, and its terms are often set by statute. Medical payments coverage is typically a smaller, medical-only benefit. See MedPay or health insurance: who pays first after a crash for how it works alongside health insurance.

Can my passengers use my PIP?

Often yes. Texas defines PIP as payable to the named insured, household members and any authorized operator or passenger of the insured vehicle, and Maryland and Oregon also cover occupants of the insured vehicle. The exact class of covered people depends on the statute and policy, and exclusions apply.

Should I reject PIP to save money?

That is a decision about your own risk, not a recommendation either way. Weigh the premium saved against the benefit you would lose, your health coverage and deductible, whether you are the sole earner, and who rides in your car. If you do reject it, keep a copy of the signed form, and put a reminder on your calendar to revisit the choice at each renewal.

Key takeaways

• An add-on state pays first-party PIP regardless of fault and places no threshold on suing the at-fault driver; a threshold no-fault state restricts lawsuits.
• Lists of add-on states disagree because PIP can be mandatory (Oregon), offered with a written rejection (Texas, Washington) or provided unless waived (Maryland); check your own state rather than a chart.
• Whether the PIP insurer can recover from your settlement differs by state: Maryland bars it, Texas allows it only against uninsured wrongdoers, Oregon allows reimbursement between insurers with protection for a not-yet-fully-compensated injured person.
• A signed rejection or waiver can bind household members and carry into renewals, so read the form and keep a copy.
• Coordinate PIP, health insurance and medical payments coverage on purpose, and keep a ledger of who paid what.
