A denial letter from an insurance company is not the final word. Many denied injury claims get reversed or settled later, either after the person sends better evidence, pushes back in writing, or brings in a lawyer who files suit. What matters is understanding exactly why you were denied and responding before your deadlines run out.
Insurers deny claims for all kinds of reasons. Some are legitimate. Many are not. Some denials are really a negotiating move, a way to see whether you will give up. Here is how to tell the difference and what to do about it.
Read the Denial Letter Closely
Insurers are generally required to explain why they are denying a claim, and most states have fair claims practices rules that require a written reason. Find that reason in the letter. It might be one sentence buried in the middle of a page of legal language, but it tells you which problem you need to solve.
Write down three things from the letter:
- The exact reason given for the denial
- The policy section or rule they are relying on, if they name one
- Any deadline to respond, request a review or appeal
If the letter is vague, call or write and ask for the specific reason in writing. You are entitled to understand why you were turned down.
The Most Common Reasons Injury Claims Get Denied
1. They say you were at fault
This is the big one. The other driver tells their insurer that you cut them off or stopped suddenly, and the insurer sides with its own customer. Without a police report, photos or witnesses, it becomes your word against theirs.
In most states, being partly at fault doesn’t wipe out your claim. Under comparative negligence rules, your payout is reduced by your share of the blame. If you were 20 percent at fault, you might still collect 80 percent of your damages. A handful of states use stricter rules where even a small share of fault can block recovery, which is exactly why insurers push hard on this point.
2. They say your injury wasn’t caused by the accident
Adjusters look for any other explanation. A gap between the crash and your first doctor visit is their favorite. So is an old injury in your medical history, like a previous back problem. Their argument is that you were already hurt before the accident.
The law in most states says the person who caused the crash is responsible for making a pre existing condition worse. If your back was manageable before and now you can’t work, that change counts.
3. They say your treatment was unnecessary or too expensive
Insurers often run medical bills through software that flags anything above what they consider normal. They may refuse to pay for chiropractic care, an MRI or extra therapy sessions. A letter from your doctor explaining why the treatment was needed often helps here.
4. Missed deadlines or paperwork
Late notice of the claim, missing forms or unsigned documents can all trigger a denial. These are usually the easiest to fix if you act quickly.
5. The policy doesn’t cover it
Sometimes the at fault driver’s policy has lapsed, or the driver was excluded from the policy, or the vehicle was being used for business in a way the policy didn’t cover. These denials are often real, but they don’t mean nobody owes you. Your own uninsured motorist coverage or another party, like the driver’s employer, may still be responsible.
Step by Step: How to Challenge a Denial
Step 1: Gather your evidence
Pull together everything that answers the reason they gave. If they said you were at fault, that means the police report, photos, dashcam footage, witness contact details and a diagram of the crash. If they said your injury wasn’t caused by the accident, that means your medical records showing when symptoms started and a note from your doctor linking them to the crash.
Step 2: Request the claim file
Ask the adjuster in writing what evidence they relied on to deny the claim. You may not get everything, but sometimes you learn that the decision was based on a mistake, like the wrong date or a misread report.
Step 3: Write a clear response letter
Keep it calm and factual. Say which decision you disagree with, why, and attach the evidence. Ask them to reconsider by a specific date. Here is a simple structure:
- Your name, claim number and date of the accident
- The reason they gave for the denial, quoted from their letter
- Why that reason is wrong, point by point
- A list of the documents you are attaching
- A request for a written response within 30 days
Send it by email and by certified mail so you have proof it arrived.
Step 4: Ask for a supervisor review
If the adjuster won’t budge, ask for the claim to be reviewed by a supervisor or claims manager. A fresh set of eyes sometimes sees that the denial won’t hold up.
Step 5: File a complaint with your state insurance department
Every state has an insurance regulator that takes consumer complaints. Filing one is free. It won’t decide your case, but the insurer has to respond to the regulator, and that often gets a stalled claim moving.
How Long Do Insurers Have to Respond?
Most states have rules that require insurers to acknowledge a claim, investigate it and make a decision within a reasonable time. The exact deadlines vary. Many states require an insurer to acknowledge communications within a couple of weeks and to accept or deny a claim within 30 to 45 days after receiving proof of loss, with extensions allowed if they explain why they need more time.
If your claim has been sitting for months with no clear answer, that delay itself can be a problem for the insurer, especially if it is your own company. Keep a log with the date of every letter, email and call. If you end up filing a complaint or a bad faith claim, that timeline becomes powerful evidence.
What a Strong Response Package Looks Like
When you push back on a denial, presentation matters more than most people expect. An adjuster handling hundreds of files is far more likely to reconsider a claim that is organized and easy to follow. A strong package usually includes:
- A one page cover letter that explains your position in plain language
- A timeline of the accident, your treatment and your communications with the insurer
- The police report and any photos or video, labeled
- Medical records in date order, with the key pages flagged
- A short letter from your treating doctor connecting the injuries to the crash
- Proof of lost income, such as pay stubs and a note from your employer
- A total of your bills and losses so far
Number every page and keep an identical copy for yourself. If you later hire a lawyer, this package saves them time and helps them evaluate your case quickly.
First Party vs Third Party Denials
It matters whose insurance denied you.
| Who denied it | Your relationship | What that means |
|---|---|---|
| Your own insurer (first party) | You are their customer and have a contract | They owe you a duty of good faith. An unreasonable denial may be a bad faith claim with extra damages in many states. |
| The other driver’s insurer (third party) | No contract with you | Your main remedy is usually a lawsuit against the at fault driver, which their insurer then has to defend and pay. |
That second row surprises a lot of people. When the other driver’s insurer denies you, you don’t sue the insurance company directly in most states. You sue the driver. Their insurer then hires a lawyer to defend them and, if you win or settle, pays up to the policy limits. Filing suit is often what finally brings a fair offer.
A Real World Example
Picture a woman in Atlanta who is sideswiped while merging. The other driver says she drifted into his lane. His insurer denies her claim, saying she was at fault. She has no witnesses, but she remembers there was a gas station on the corner.
She calls the station that same week and asks them to save their camera footage. The video shows the other car moving into her lane. She sends it to the adjuster with a short letter, and the denial is reversed within a month. Without that video, she would likely have been stuck. The lesson is to look for evidence quickly, because businesses often record over their footage within days or weeks.
Mistakes That Make a Denial Harder to Beat
- Arguing on the phone without writing it down. Phone calls leave no record. Follow every call with a short email summarizing what was said.
- Posting about the accident on social media. Adjusters check. A photo of you at a barbecue can be used to argue you weren’t really hurt.
- Stopping medical treatment. If you stop going to the doctor while you fight the denial, it looks like you got better.
- Giving up. Some denials are tests. A person who never responds saves the insurer money.
- Losing your temper. Angry emails and threats rarely help. Calm, documented persistence works much better and looks far better if a regulator or judge ever reads the file.
- Waiting too long. The statute of limitations keeps running while you argue with the adjuster.
Partial Denials and Lowball “Approvals”
Not every denial says “denied” at the top. Sometimes an insurer accepts the claim but refuses to pay part of it, such as your physical therapy or your lost wages. Other times it approves the claim at a figure so low it amounts to a denial. Treat these the same way. Ask for the specific reason each item was cut, and answer it with evidence. A partial denial still deserves a written response.
When a Lawyer Makes Sense
You can handle a small denial yourself, especially one based on missing paperwork. For anything else, a personal injury lawyer is worth a free consultation. Lawyers know which denials are weak, they can file a lawsuit to stop the deadline from running, and insurers tend to treat represented claimants differently.
Most injury lawyers work on contingency, so you don’t pay anything upfront. If the denial involves your own insurer acting unreasonably, ask specifically about bad faith, because that can open the door to more than the original claim amount.
What to Do Next
Find the exact reason in your denial letter, note your deadlines, and gather the evidence that answers it. Send a written response, ask for a supervisor review, and file a complaint with your state insurance department if you are being stonewalled. If you were seriously hurt, talk to a lawyer before the statute of limitations gets close. A denial is often the start of the negotiation, not the end of it.

Frequently Asked Questions
Can an insurance company deny a claim without a reason?
In most states insurers must give a written reason for denying a claim. If yours didn’t, ask for one in writing.
How long do I have to appeal a denied injury claim?
Insurers may set internal review deadlines, but the most important deadline is your state’s statute of limitations to file a lawsuit, which is usually two to three years for injuries.
Can I sue the other driver's insurance company directly?
In most states you sue the at fault driver, not their insurer. The insurer then defends the driver and pays any settlement or judgment up to the policy limits.
What is insurance bad faith?
Bad faith is when an insurer unreasonably denies, delays or underpays a claim it owes. It usually applies to your own insurer and can lead to extra damages in many states.
Will filing a complaint with the state insurance department help?
It can. The regulator won’t decide your claim, but the insurer must respond to it, which often speeds things up.
Is it worth hiring a lawyer after a denial?
If you have real injuries or lost income, usually yes. Free consultations let you find out without any cost.
