Insurance Claim Denial: Why It Happens and What to Do Next

Insurance denied your claim? Learn the common reasons, how to appeal, the deadlines that apply, and when a denial may be bad faith, including in Nevada.

Published November 07, 2026

A denial is not always the final word. Start by getting the reason in writing, then compare it with your policy, gather the documents that answer it, and file your appeal before the deadline in your policy or plan runs out. If the insurer ignored evidence, skipped an investigation or gave no real reason, the denial may cross into bad faith. That is when a lawyer can help. This guide covers the common reasons for denials, the appeal steps, the timelines insurers must meet (with Nevada’s rule), and how to decide when to call an attorney.

What a claim denial actually means

A denial is the insurer’s decision that it will not pay all or part of what you asked for. It can arrive as a letter, an email or a line on an explanation of benefits. Sometimes it is a flat refusal. Sometimes it is a partial payment that leaves most of the loss uncovered.

A denial is a position, not a verdict. Insurers make mistakes, miss documents and apply policy language in ways that can be challenged. Your job is to find out which kind of denial you have: one the policy supports, or one that does not hold up.

Common reasons insurers deny claims

The reasons differ a little by type of insurance, but they cluster into a few groups.

Car insurance. Nolo’s guide to denied car insurance claims lists these common grounds:

Health insurance. HealthInsurance.org points to services that are not covered or not considered medically necessary, out-of-network care, missing prior authorization, and coding or timing problems. The Connecticut Office of the Attorney General adds coordination of benefits issues and billing errors to that list.

Any policy. AAA’s overview names administrative error, late filing, unpaid premiums, insufficient documentation, losses the policy does not cover, and claims that fall below the deductible.

Notice how many of these are fixable. A missing police report, a coding mistake or an unsent record is not the same as a true coverage exclusion.

What to do in the first days after a denial

  1. Get the reasons in writing. If the insurer only told you by phone, ask for a written explanation. Nolo advises getting the reasons in writing as the first step.
  2. Read the policy language it cites. Find the provision, exclusion or condition, and read the definitions that go with it. In Nevada, an insurer may not deny a first-party claim on the basis of a specific provision, condition or exclusion unless the denial refers to it, and the denial must be in writing, under Nevada Administrative Code 686A.675.
  3. Match the reason to the evidence. If the insurer says you did not prove your loss, supply what is missing. Nolo lists police reports, accident or scene photos, repair estimates, and medical records and bills.
  4. Write down the calendar. Note the date you received the denial, the appeal deadline in your policy or plan, and any lawsuit deadline. Do not assume the clock stops while you talk to the adjuster.
  5. Stop giving recorded statements without a plan. If the claim is large or contested, talk through what you will say before you say it. Our guide to insurance adjuster tactics in Nevada explains what adjusters tend to ask and why.

How to appeal a denied claim

An appeal is a formal request that the insurer reconsider. The process depends on the kind of coverage.

Gather the right documents

The Connecticut Attorney General’s office recommends collecting the denial letter, your policy or plan document, relevant medical records and your providers’ treatment recommendations. It also advises following the plan’s procedures exactly, writing a professional appeal letter, sending materials by certified mail and keeping complete copies of everything you submit.

Write a letter that answers the denial

Address the stated reason, point by point. If the insurer says a treatment was not medically necessary, attach a doctor’s statement explaining why it was. If it says the vehicle was not covered, attach the declarations page. Keep the tone factual. The letter may later be an exhibit.

Know your options beyond the appeal

For a denied first-party car claim, Nolo notes you can submit more evidence, follow your policy’s appeal steps, or get outside help, such as a complaint to your state insurance commissioner or an independent claims adjuster. In Texas, for instance, the Office of Public Insurance Counsel lists contacting an attorney, paying a qualified appraiser, or filing a complaint with the state insurance department as ways to dispute a payment. Nevada drivers can take similar steps through the state’s insurance regulator.

Deadlines: appeals and insurer response times

There are two separate clocks: how long you have to appeal, and how long the insurer has to decide.

Situation Your deadline Insurer’s deadline
Health plan internal appeal 180 days from the denial notice Notice of denial: 72 hours for urgent care, 15 days for prior authorization, 30 days for services already received
Group health plan under ERISA At least 180 days Urgent appeals 72 hours, pre-service 30 days, post-service 60 days
Other ERISA benefits (life, pension) At least 60 days Set by plan and federal rules
Nevada first-party claim Per your policy Accept or deny within 30 working days of properly executed proofs of loss; pay within 30 days of acceptance

The Nevada row comes from NAC 686A.675. If an accepted claim is not paid on time, the insurer owes interest. Other states set their own numbers. Texas, for example, requires a written decision within 15 business days after the insurer has everything it needs, with a possible extension, under Insurance Code section 542.056. Oregon uses 30 days under OAR 836-080-0235. Always check the rule for your own state and policy.

An appeal deadline is different from the deadline to sue. A lawsuit against a negligent driver or property owner has its own filing limit. Our explainer on Nevada deadlines and the statute of limitations shows how these time limits differ. Ongoing talks with an insurer do not automatically pause them.

Car accident denials in Nevada

In Las Vegas, Henderson, North Las Vegas, Reno and the rest of Clark and Washoe counties, car accident denials often rest on a few predictable arguments: disputed fault, a gap in treatment, a pre-existing condition, or a claim that your coverage did not apply. Two points are worth knowing early.

First, who is denying matters. If the at-fault driver’s insurer denies your injury claim, that is a third-party claim, and the dispute is really about liability and damages. If your own insurer denies a claim, such as medical payments or uninsured motorist coverage, that is a first-party claim, and the insurer owes you duties under your policy. Our guide to uninsured and underinsured motorist coverage explains the difference, and the piece on stacked and unstacked coverage shows why some Nevada drivers have more coverage available than they realize.

Second, rideshare and commercial crashes bring more than one policy into play. If you were hurt in a Uber or Lyft trip, the right coverage depends on the driver’s app status at the time of the crash, and denials often come from insurers pointing at each other.

When a denial may be bad faith

Insurers can deny claims. What they cannot do is deny them unreasonably. Insurance bad faith generally means an unreasonable refusal to provide a benefit legitimately due under a policy. Nolo gives examples: refusing to pay a legitimate claim, failing to reasonably investigate, giving no reason for the denial, knowingly departing from state claims-process rules, or purposely ignoring information that supports the claim.

The legal test varies by state, which is why local law matters:

The point is not to memorize these cases. It is that the same conduct can be actionable in one state and not in another, so a Nevada claim should be reviewed under Nevada law. If you suspect your insurer is stalling or hiding behind a weak reason, see our page on Nevada bad faith insurance attorneys.

Our perspective on denied claims

Before we represent injured people, we learn how the other side works. Insurers train their adjusters to look for the weakest link in a file: a gap in treatment, a late report, a vague statement. A denial often says more about the insurer’s strategy than about the strength of your claim.

We prepare every case as if it is going to a jury. That means preserving evidence early, talking to clients directly and honestly, and building a record that shows what the insurer knew and when. When an insurer ignores that record, we are prepared to challenge it in court.

No lawyer can promise a result, and we do not. What we can promise is a clear explanation of your options and personal attention throughout.

When an insurance claim denial lawyer can help

You do not need a lawyer for every denial. A simple paperwork fix on a small claim may be resolved with one letter. Consider legal help when:

Before you hire anyone, ask how fees work. Many injury firms, including ours, work on a contingency basis, which means fees come from a settlement or judgment. Ask what costs are advanced, who handles the case day to day, and whether the firm tries cases or only settles them.

FAQ

How long does an insurer have to accept or reject a claim?

It depends on the state and the type of insurance. In Nevada, an insurer must tell a first-party claimant whether it accepts or denies the claim within 30 working days after receiving properly executed proofs of loss. If it accepts, payment is due within 30 days. Texas and Oregon use different timelines, so check your own state’s rules.

Can I appeal an insurance denial more than once?

Often, yes. Many health plans have an internal appeal followed by an external review, and a state insurance regulator can take a complaint at any stage. Car and property policies may have shorter, policy-specific steps. Read your policy and the denial letter for the exact process and deadlines.

Is a denial the same as bad faith?

No. An insurer is allowed to deny a claim that the policy does not cover. Bad faith generally involves an unreasonable denial, such as no real investigation, ignored evidence or no stated reason. Standards differ by state, so a lawyer should review the facts under your state’s law.

What if my car accident claim was denied by the other driver’s insurer?

That is a liability dispute, not a coverage decision on your own policy. The insurer is saying its driver was not at fault or that your injuries are not what you say they are. Gather medical records, photos and the police report, and talk to an injury attorney before giving a recorded statement or accepting an offer.
