How does a personal injury settlement work in the United States?

A personal injury settlement is a contract: the injured person gives up the legal claim, in a signed release, in exchange for a sum negotiated with the other side, which in most cases means the other side's liability insurer. The path to that contract runs through medical treatment and documentation, a demand letter, the insurer's evaluation, negotiation, sometimes mediation or a lawsuit, and then the resolution of liens before the client receives a net amount.

This article covers how the process works in the United States, where the rules on deadlines, fees and liens are largely set state by state, with a federal layer for Medicare and income tax. It is general information, not legal or tax advice.

The amount printed on the settlement agreement is not the amount the injured person keeps. The attorney's fee, the costs of the case and the parties with a right to reimbursement all come out of the gross figure, and the order and method of those deductions are set by the fee agreement, by state law and by federal rules. A lawyer, an adjuster, a lien holder or a claimant who understands each stage can read a settlement offer for what it will really deliver.

What are the stages of a personal injury settlement?

A personal injury settlement moves through seven stages: treatment and documentation, the demand, the insurer's evaluation, negotiation, an agreement recorded in a release, the resolution of liens, and the disbursement of the net amount to the client. A lawsuit may be filed at any point before the filing deadline without ending the negotiation, and most of the stages continue in the same way once a case is in court.

The stages overlap in practice. Lien holders are identified while treatment is still under way, and the tax character of the payment is settled by the wording of the agreement rather than after it. The sequence below is the order in which each stage must be finished, not the order in which work on it starts.

Why do treatment and documentation come before any negotiation?

Treatment and documentation come first because a settlement is final: once the release is signed, the claimant cannot return for more money if the injury turns out worse than expected, so the claim is normally valued only when the medical outcome is known. Lawyers and adjusters refer to this point as maximum medical improvement, the stage at which the condition has stabilised and future needs can be estimated.

The file built during this period is what the insurer will later evaluate. It usually contains:

• medical records and itemised bills from every provider, from the emergency visit to the last therapy session;
• a physician's statement on prognosis, permanent limitations and future care, where there are any;
• proof of lost income: pay records, an employer's letter, or tax returns and invoices for a self-employed person;
• evidence of fault: the police or incident report, photographs, witness statements, and expert analysis in a contested case;
• records of how the injury changed daily life, which support the non-economic part of the claim.

Gaps weaken a claim more than almost anything else in this phase. A month without treatment, a missed referral or a prior injury to the same body part gives the adjuster a reason to argue that part of the condition has another cause.

Two administrative steps also belong here. The insurer is notified of the claim early, well before any demand, so that coverage can be confirmed. And if the injured person is a Medicare beneficiary, the case is reported to the Benefits Coordination and Recovery Center: the Centers for Medicare & Medicaid Services (CMS) states that a pending liability, no-fault or workers' compensation case must be reported, and that reporting is the first step of its recovery process.

What goes into the demand letter and the amount claimed?

A demand letter states the facts, explains why the insured party is liable, describes the injuries and treatment, itemises the losses and asks for a specific sum, usually with a date by which the insurer is asked to respond. The amount claimed is the total of economic damages, which can be proved with documents, and non-economic damages, which cannot be read off a bill.

Economic damages, often called special damages, are past medical expenses, the estimated cost of future care, lost income to date and any loss of future earning capacity, together with out-of-pocket items such as travel to treatment. Non-economic damages, or general damages, cover pain and suffering, loss of enjoyment of life and similar harm. No statute sets a formula for them. Negotiators use rules of thumb, such as a multiple of the medical expenses or a daily amount, but these are conventions of negotiation, not law, and results vary with the severity and permanence of the injury, the venue and the credibility of the evidence. Some states cap non-economic damages in certain kinds of case, so the applicable state law has to be checked before a figure is put forward.

The worked example of this article follows one claim from start to finish. Call the claimant Elena: a 68-year-old consultant, enrolled in Medicare and still working, injured when another driver ran a red light. Her figures are illustrative.

The economic items add up to $62,000, and the non-economic figure brings the demand to $200,000. A demand is an opening position, and both sides know it. Its job is to be supported well enough that the adjuster can justify a serious evaluation to the people who approve the payment.

How does the insurer evaluate the claim, and what do policy limits change?

The insurer evaluates a claim on three questions: whether the policy covers the event, how much of the fault lies with its insured, and what the documented damages are worth; the policy limit then caps what the insurer itself will pay, whatever the injury is worth. An adjuster who values a claim at more than the limit can offer the limit and no more.

Coverage comes first. The adjuster confirms that the policy was in force, that the event falls within it and that no exclusion applies. Liability comes second. Where the injured person shares some of the fault, state law decides the effect: the states use different comparative or contributory negligence rules, and under them a claimant's share of fault can reduce the recovery or, in some states, bar it. The damages review comes third, and it is line by line: whether each treatment is related to the accident, whether the charges are reasonable, whether the time off work is supported.

From that review the insurer sets a reserve and gives the adjuster an authority, the highest figure the adjuster may agree without going back for approval. A first offer usually sits well under that authority, for the same reason the demand sits above the claimant's expectation.

Policy limits shape the whole negotiation in a serious case. If the damages plainly exceed the limit, the practical questions become whether other coverage exists (an employer's policy, an umbrella policy, the claimant's own underinsured motorist coverage) and whether the at-fault person has assets worth pursuing. In Elena's example, the other driver carries a $250,000 limit, which is above the demand, so the limit does not constrain the negotiation.

How do negotiation and mediation lead to an agreed figure?

Negotiation leads to an agreed figure through a series of offers and counter-offers in which each side moves in exchange for a movement from the other, until the remaining gap is smaller than the cost and risk of continuing. Mediation adds a neutral third person who helps the parties close that gap but who decides nothing.

Each move carries a reason. The claimant's side answers a low offer by pointing to the evidence the offer overlooks; the adjuster answers a high demand by pointing to the weaknesses in the file. In Elena's example, the insurer's first answer to the $200,000 demand is $90,000. Her lawyer counters at $175,000, the insurer moves to $125,000, and the parties settle in mediation at $150,000.

A mediation is usually a single session. The mediator, often a retired judge or an experienced litigator, meets the two sides together and then separately, tests each side's view of the risks and carries proposals between the rooms. What is said there is generally confidential under state law or the mediation agreement, and no one is bound unless a written agreement is signed.

The decision to accept belongs to the client. Under Rule 1.2(a) of the American Bar Association's Model Rules of Professional Conduct, which the states have adopted with their own variations, a lawyer shall abide by a client's decision whether to settle a matter. The lawyer advises, gives a view of what a jury might award and what trial would cost, and explains what the offer would net after deductions; the client says yes or no.

When does a lawsuit have to be filed, and what is the statute of limitations?

A lawsuit has to be filed before the statute of limitations expires, a deadline set by each state, and a claim filed late can be dismissed however strong it is. Negotiating with an insurer does not, in general, stop that clock, so a claim that has not settled as the deadline approaches is filed to preserve it.

The deadline differs from state to state and, within a state, by type of claim. California illustrates the pattern. According to the California Courts self-help guide, the deadline for a personal injury claim is two years from the date of injury. The same guide gives a different rule for medical malpractice: one year from the date the plaintiff knows or should have known about the injury, or three years from the date of the injury, whichever is earlier. It also warns that a claim against a government agency must first be presented to that agency by a much earlier deadline. Another state will have its own periods and its own exceptions, for instance for minors or for injuries discovered late, so the rule is always checked for the state and the type of defendant concerned.

Filing suit does not mean going to trial. It opens discovery, in which each side can obtain documents and sworn testimony from the other, and it places the case on a court schedule. Both effects tend to move a negotiation: the insurer sees how the witnesses perform, the claimant sees the defence evidence, and a trial date gives both a reason to decide. A settlement reached after filing ends with a dismissal of the lawsuit, and some settlements need a judge's approval, notably those involving a minor.

What does the release give up?

The release gives up the claimant's right to pursue the released parties for anything arising from the incident, including harm that appears or worsens after signing. In exchange the claimant receives the settlement sum, and the dispute ends without any finding or admission of fault.

A settlement agreement and release normally sets out who is released (the at-fault person, the insurer, and often employers and affiliates), which claims are covered, the amount and the time for payment, a statement that liability is not admitted, and who is responsible for liens. That last clause matters more than its length suggests: the claimant typically agrees to satisfy every lien out of the proceeds and to protect the released parties if a lien holder later comes after them. Insurers also ask for the information they need for their own Medicare reporting. Some agreements add a confidentiality clause.

The scope of the release should match the claims being paid for. Where several parties may be liable and only one is settling, the wording has to preserve the claims against the others, and state law on the effect of releasing one of several wrongdoers varies.

Is the settlement paid as a lump sum or as structured payments?

A settlement is paid either as a single lump sum or as a structured settlement, in which part or all of the money arrives as periodic payments over years, usually funded by an annuity. The choice is made before the release is signed, because the payment schedule is written into the agreement, and federal tax law treats damages for physical injury the same way whether they are received as lump sums or as periodic payments.

Which liens must be resolved before the client is paid?

The liens to resolve are the reimbursement claims of those who paid for or provided the injury-related care: Medicare, Medicaid, private or employer health plans, and hospitals or other providers that treated the claimant against a promise of payment from the recovery. Each is governed by its own rules, and the client's net cannot be calculated until each one has a final figure.

Medicare is the lien with a uniform federal procedure. CMS describes the payments Medicare makes for care that another payer may be responsible for as conditional payments, and states that they must be repaid when a settlement, judgment, award or other payment is made. The process CMS describes runs as follows. After the case is reported, the Benefits Coordination and Recovery Center sends a Rights and Responsibilities letter, and within 65 days of that letter a Conditional Payment Letter listing the claims Medicare has paid so far. The beneficiary or the lawyer can dispute items unrelated to the injury. If a settlement has already occurred when the case is reported, a Conditional Payment Notice is issued instead, with 30 calendar days to respond, failing which a demand letter issues automatically without any reduction for fees or costs. The demand letter states the amount owed, and CMS notes that interest accrues from the date of the demand letter and is assessed for each 30-day period the debt remains unresolved.

The reduction for fees and costs is set by a federal regulation, section 411.37 of title 42 of the Code of Federal Regulations. Where Medicare's payments are less than the settlement, the claimant's procurement costs (the attorney's fee and case costs) are divided by the settlement amount, that ratio is applied to Medicare's payments, and the product is Medicare's share of the cost of obtaining the recovery, which is subtracted from what Medicare is owed. Where Medicare's payments equal or exceed the settlement, the recovery is the whole settlement less the procurement costs.

Other lien holders do not follow that formula. State Medicaid programs, employer health plans and private insurers assert reimbursement rights under their own statutes or plan terms, and hospitals and providers under state lien laws or their agreements with the patient. Whether and by how much each will reduce its claim depends on those rules and on negotiation. Each claim is identified early, confirmed in writing and settled before the client's share is released.

How are personal injury settlement proceeds taxed at the federal level?

Under federal income tax law, damages received on account of personal physical injuries or physical sickness are excluded from gross income, apart from punitive damages, while interest and amounts that replace something other than a physical injury are generally taxable. The exclusion is in section 104(a)(2) of the Internal Revenue Code, and the Internal Revenue Service (IRS) frames the test as a question: what was the settlement intended to replace?

The IRS's guidance on the tax implications of settlements and judgments explains that all income is taxable unless a provision exempts it, and that the word "physical" was added to the exclusion in 1996. The same guidance states that compensatory damages, including lost wages, received on account of a personal physical injury are excludable. IRS Publication 4345, in its September 2023 revision, sets out how each category is reported.

The wording of the agreement therefore has consequences. Because the IRS looks at what each payment replaces, an agreement that allocates the sum among categories, where there is a real basis for the allocation, gives a clearer answer than one that states a single undivided amount. State income tax is a separate question, and a claimant with any taxable component should take advice from a tax professional before signing, not after.

How much of the gross settlement does the client receive?

The client receives the gross settlement less the attorney's fee, the case costs and the liens, and in a claim with significant medical bills the net is often close to half of the gross figure. In the worked example it is $76,200 out of $150,000, or 50.8%.

The payout mechanics are short. The insurer pays the settlement to the claimant's law firm, which deposits it in a client trust account, pays the lien holders and its own fee and costs once the funds have cleared, and remits the balance to the client. The ABA's Model Rule 1.5(c) requires a contingent fee agreement to be in a writing signed by the client, stating the percentage and whether expenses are deducted before or after the fee is calculated, and requires a written statement at the end showing the outcome, the remittance to the client and how it was determined.

Elena's fee agreement provides for a contingency fee of one third of the gross recovery, calculated before costs. That rate is illustrative: fee percentages are set by agreement, vary between firms and stages of a case, and are limited by statute in some states and types of claim. The firm advanced $4,000 in costs for records, an expert review and the mediator's fee. Medicare made $20,000 in conditional payments. A therapy clinic that Medicare did not cover is owed $9,500 and agrees to accept $7,000.

The Medicare figure follows the regulation's ratio. Procurement costs are the $50,000 fee plus the $4,000 in costs, $54,000, which is 36% of the $150,000 settlement. Medicare's share of those costs is 36% of $20,000, or $7,200, so the amount to repay is $12,800.

The deductions total $73,800. Three points in this statement are worth checking in any real one. The first is the base of the fee: had the agreement calculated the one third after costs, on $146,000, the fee would have been $48,666.67, which is $1,333.33 less. The second is the Medicare reduction: without a timely response and the procurement cost reduction, the repayment would have been the full $20,000, which is $7,200 more. The third is the clinic's reduction of $2,500, which rests on negotiation alone and could not have been assumed.

The same statement can be drafted at any offer on the table. A client deciding whether to accept is better served by the net at that figure than by the gross number alone, since the costs and provider balances do not shrink with the offer.
