Why the clock really starts when treatment ends
Most people expect the timeline to run from the date of the accident. In practice it runs from the point your injury is understood. An insurer will not pay for treatment it cannot see yet, and a lawyer will rarely send a settlement demand while you are still in physical therapy with no end date.
The milestone everyone is waiting for is called maximum medical improvement, or MMI. It means you have either recovered or your doctor believes you have improved as much as you are going to. At that point your medical bills stop being a guess, and any lasting problems can be described in a report.
That is why two people hurt in the same crash can have very different timelines. Someone with a sprained neck who is fine after eight weeks of physio may settle within four or five months of the accident. Someone with a herniated disc who tries injections first and then needs surgery might not reach MMI for a year.
A typical timeline, stage by stage
The ranges below are what you commonly see in car accident and other injury claims handled with the insurer. Your claim can move faster or slower at any step.
| Stage | What happens | Typical length |
|---|---|---|
| Medical treatment | You treat until you recover or reach MMI | A few weeks to a year or more |
| Gathering records | Bills, records and wage proof are requested from every provider | 2 to 8 weeks |
| Demand letter | A written demand with records, bills and a figure goes to the insurer | Sent once records are complete |
| Insurer review | The adjuster evaluates the demand and replies with an offer | Often 30 to 60 days |
| Negotiation | Offers and counteroffers go back and forth | A few weeks to a few months |
| Release and payment | You sign a release, liens are resolved and funds are paid out | Often 2 to 6 weeks |
If the claim does not settle and a lawsuit is filed, add the litigation stage. Written discovery, depositions and medical examinations usually take many months, and trial dates depend on how busy the local court is. Most filed cases still settle before trial, often after depositions or at a court-ordered mediation.
The five things that slow a claim down
1. Treatment that is still going on
This is the most common reason and usually a sensible one. Settling before you know whether you need surgery is the fastest way to leave money on the table, because a signed release normally ends the claim for good.
2. Arguments about fault
If the other driver's insurer says you caused the crash, or blames you partly, expect a slower claim. Fault matters a great deal in the United States because your state's negligence rule can reduce your compensation or, in a few states, bar it completely. Police reports, photos, dashcam footage and witness details shorten this argument.
3. Missing paperwork
Hospitals and imaging centers can be slow to release records and itemized bills. A demand that is missing a provider's bill will get a lower offer or a request to send the rest, which restarts the review.
4. Liens that have to be settled
If Medicare, Medicaid, an employer health plan or a hospital paid for your care, they may have a right to be repaid from the settlement. Medicare in particular will not issue its final figure until the claim settles, and that step alone can take weeks. Our guide to medical liens explains how this works and how the amounts are reduced.
5. Limited insurance
When your losses are larger than the at-fault driver's policy, the insurer may pay its limit fairly quickly, but getting anything beyond that means claiming against your own underinsured motorist coverage or looking at the driver's personal assets. That is a second negotiation with its own timeline.
What you can do to keep things moving
You cannot make an adjuster work faster, but you can remove the excuses for delay:
- Keep going to your appointments. Gaps in treatment are used to argue that you had recovered, and they also stretch the timeline.
- Keep a simple folder of every bill, receipt, pay stub and letter. Ask each provider for an itemized bill, not just a balance.
- Write down the other driver's insurer, the claim number and the adjuster's name, and put every conversation in writing afterwards.
- Get the police report early. Some departments take weeks to release it.
- Find out the other driver's policy limit if you can. It tells you whether a quick settlement is realistic.
- Answer requests for information promptly, especially wage verification from your employer.
Should you settle quickly?
Sometimes a fast settlement is the right call. If your injury was minor, you have fully recovered and the offer covers your bills, lost pay and a fair amount for what you went through, there is little to gain from waiting.
The risk is settling before the full picture is known. A common example: someone accepts $4,500 six weeks after a rear-end collision, then develops pain down one arm, has an MRI that shows a disc problem and ends up needing injections that cost more than the whole settlement. The release they signed covers all injuries from that accident, known or unknown. There is no going back.
Before you accept, check the offer against your own numbers. The settlement calculator gives you a range from your actual losses and tells you whether an offer sits below, inside or above it.

Your filing deadline keeps running
Negotiating with an insurer does not pause the statute of limitations. In most states you have two or three years from the accident to file a lawsuit, and a few states allow only one. If the deadline passes, the insurer has no reason to pay you anything, because you can no longer sue.
Claims against a city, county, state agency or public transit authority are stricter still. Many require a formal written notice within months, not years. If a government vehicle or a public property defect was involved, find out the notice rule straight away. Our statute of limitations guide lists the general deadline for each state.
How long after settling do you get paid?
Once you agree a figure, the insurer sends a release for you to sign. After it receives the signed release, it issues payment. Many states have rules requiring insurers to pay within a set number of days after a settlement is agreed, although the exact rule varies.
If you have a lawyer, the check goes into the firm's trust account. The firm then pays any liens and case costs, takes its fee and sends you the balance with a written settlement statement. Waiting for a lien holder to confirm its final figure is the usual reason this step takes longer than a couple of weeks.
Three realistic examples
A minor rear-end collision, no lawyer. Neck and shoulder strain, six weeks of physical therapy, $3,800 in bills and a week off work. Liability is clear. Records are gathered within a month of the last appointment, the insurer makes an offer within a few weeks, and after one counteroffer the claim settles. Total time: roughly four to five months from the accident.
A herniated disc with a lawyer. Eight months of treatment including two injections, no surgery. Records take six weeks to collect, the demand goes out, and the insurer takes about six weeks to respond. Two months of negotiation follow. Total time: roughly a year to fourteen months.
Disputed fault at an intersection. Each driver says the other ran the light. The insurer denies the claim, the lawyer files suit before the deadline, and the case settles at mediation after both drivers are deposed. Total time: often two years or more.
The short version
- Your treatment sets the pace. Settling before you reach maximum medical improvement is risky.
- A claim with clear fault and complete paperwork can settle within months of finishing treatment.
- Disputed fault, serious injuries, liens and lawsuits each add months.
- The statute of limitations keeps running while you negotiate.
- Payment normally follows within a few weeks of signing the release, once liens are dealt with.
