Re: Request for reconsideration of denied claim

Named insured: [Name exactly as it appears on the declarations page]
Policy number: [Policy number]
Claim number: [Claim number]
Date of loss: [Date of loss]
Insured property or vehicle: [Property address, or vehicle year, make, model and VIN]
Denial letter: [Date of the denial letter, and whether it denies all or part of the claim]

Dear [Adjuster's name]:

I am writing to ask [Insurance company name] to reconsider its decision, in your letter dated [date of denial letter], to deny [all / part] of the claim above. The policy covers this loss for the reasons set out below, and I ask you to reverse the denial and pay the claim.

1. What happened

[Two to four sentences of plain fact: what was damaged, when and how it happened, when you found it, and what you did to prevent further damage.]

I reported the loss on [date reported] by [phone / online / to your agent, name]. [Name of adjuster or inspector] inspected on [date of inspection].

2. The reason given for the denial

Your letter gives this reason for the denial:

"[Quote the denial reason exactly, word for word, and note the page or paragraph of the letter.]"

The letter relies on [the policy form number, section, and name of the exclusion, condition, or limitation the insurer cited].

[If the letter gives more than one reason, list each one here and answer each in section 4. The Denial Reason Map sheet lines them up side by side.]

3. The policy language that supports coverage

Coverage grant. The policy states: "[Quote the insuring agreement or coverage section that covers this kind of loss.]" ([Form number], page [page], section [section])

The provision the denial relies on. The full wording is: "[Quote the entire exclusion, condition, or limitation the insurer cited, not only the part in the denial letter.]" ([Form number], page [page])

Why it does not apply here. [Explain in plain terms why the facts of this loss fall outside that provision, and point to the evidence. Example: the exclusion is for damage that happened slowly over time, and the plumber's report says the pipe burst on one day.]

Other policy terms that matter. [Any exception to the exclusion, additional coverage, or endorsement listed on the declarations page that changes the result. Delete this paragraph if there is none.]

4. Response to each denial reason

Reason 1: [Short name for the reason]

What the denial says: "[Quote]"
Why it does not apply: [Your answer, tied to the policy wording above]
Evidence: Exhibit [letter]

Reason 2: [Short name for the reason] [Delete if the letter gives only one reason.]

What the denial says: "[Quote]"
Why it does not apply: [Your answer]
Evidence: Exhibit [letter]

5. Evidence enclosed

Exhibit A: Denial letter dated [date]
Exhibit B: Declarations page and the policy pages quoted above ([form numbers])
Exhibit C: [Number] photos of the damage, taken on [dates]
Exhibit D: [Report or estimate from a contractor, mechanic, engineer, or other professional], dated [date]
Exhibit E: [Invoices, receipts, police or fire report, weather report, or repair records]
Exhibit F: Log of calls, emails, and inspections on this claim

[Send copies and keep the originals. Number every page so the adjuster can cite it.]

6. What I am asking for

Reverse the denial and accept coverage for [the loss / the specific items denied].
Pay [$ amount] based on [Exhibit D], less the [$ deductible] deductible. [Or, if the amount is not yet known: resume adjusting the claim and send a written estimate.]
If you uphold any part of the denial, explain in writing the specific policy provisions and facts you rely on for each part, and send copies of any reports, estimates, photos, or statements the decision is based on.
If I do not already have one, send a complete copy of the policy that was in force on the date of loss, with all endorsements.
If you need anything else to decide, tell me in writing exactly what it is.

7. Response requested

Please respond in writing by [response date]. [Choose a date that fits your state's claim handling time limits and any appeal deadline stated in the denial letter. These rules vary by state.]

I also ask that [Insurance company name] handle this request within the time limits set by [state] law. [Cite a specific statute or regulation only after you have checked it.]

Please send all communication about this claim to [email or mailing address].

Nothing in this letter waives any of my rights under the policy or the law.

Sincerely,

[Signature]
[Printed name]
[Title, if writing for a business]
[Business name, if any]

Enclosures: Exhibits A to [last exhibit letter]
cc: [Your insurance agent or broker, if any]

Notes for you, delete before sending:

Check the policy's "Suit Against Us" or "Legal Action Against Us" condition for a time limit to sue. Asking for reconsideration may not pause it.
If the insurer upholds the denial or does not answer, other options include a complaint to your state insurance department, a licensed public adjuster, or a lawyer. Each has different costs and limits. This template does not recommend one.

How to appeal a denied insurance claim

To appeal a denied insurance claim on a home, auto or business policy, write to the insurer and ask it to reconsider. A strong appeal letter quotes each reason the insurer gave, answers it with the policy's full wording and dated evidence, and asks for one specific result by a set date. Health plans in the US follow their own process: an internal appeal, then an external review¹.

One rule matters more than any other: answer every reason the insurer gave. If you rebut two reasons and skip the third, the insurer can keep the denial on the one you skipped.

Confirm what was denied, and why

An appeal is for a claim under your own policy that the insurer refused, in whole or in part. If your claim is against someone else's insurer, such as the other driver's, a demand letter fits better. A medical practice appealing a health plan should use the insurance denial appeal letter template.

Next, get the reasons in writing. The National Association of Insurance Commissioners (NAIC) is the standard-setting group run by state insurance regulators. Its model regulation says an insurer may not deny a claim based on a specific policy provision, condition or exclusion² unless the denial refers to it. The denial must also be in writing.

States set their own rules. Washington's current rule, in force since October 18, 2026, gives insurers 30 calendar days after notice of a claim³ to decide, or to say why they need more time. A denial there must name any provision it relies on. If yours came by phone or names no provision, ask for it in writing before you appeal.

Read the denial against the whole policy

A denial letter may quote only a sentence or two. Find the full provision and read all of it, including any exception, such as "This exclusion does not apply to."

Then get the whole policy. United Policyholders, a nonprofit that advocates for policyholders, notes that the declarations page lists your coverage amounts and endorsement codes⁴. It warns that what you see there is not always what you've got. Pull every form listed, and ask the insurer for any you lack, since an endorsement can add coverage or take it away.

Where to look in your policy

Part	What it tells you
Declarations page	Who and what is insured, limits, deductibles, and every form and endorsement in force
Insuring agreement	What the policy promises to pay for; your loss should fit here first
Definitions	What words in quotation marks or bold mean in this policy
Exclusions	What isn't covered, and the exceptions that restore coverage
Conditions	Your duties after a loss, appraisal, and the time limit to sue
Endorsements	Changes to the base form, which control where the two conflict

Map every reason, and what's missing

Before you write, give each reason its own row, as the template's Denial Reason Map does. Record the insurer's exact words and where they appear, the provision cited, the wording that supports you, why the reason doesn't fit your facts, and your proof. Add a last row for anything the decision skipped, such as damaged contents the letter never mentions.

ExampleOne row of a Denial Reason Map, filled inAn illustrative example written for this guide. The policy and numbers are made up.

Denial reason: "The roof damage results from wear, tear and deterioration, which the policy excludes." (Letter of May 6, page 1, paragraph 2)
Provision relied on: Form HO-100, Section I Exclusions, wear and tear (page 9)
Wording that supports coverage: The dwelling is covered for direct physical loss unless excluded (page 7). No exclusion mentions hail.
Why it does not apply: The damage is fresh hail impact, not age. Our roofer found 14 hail strikes on the south slope, and a 2025 inspection rated the roof sound.
Evidence: NOAA Storm Prediction Center report of 1.5-inch hail in our county on March 14 (Exhibit C), roofer's report (Exhibit D), 2025 inspection (Exhibit E)
Still needed: The insurer's inspection photos, requested May 12

Exact words, with a location. The adjuster can find the sentence you're answering.
Independent, dated proof. A weather record and an older inspection answer the claim that the damage is old.
Gaps in the open. What's still missing becomes a request in the letter.

Prove the facts the denial gets wrong

Many denials rest on a fact: when the damage happened, what caused it, or when you reported it. Answer each one with dated records made as close to the loss as you can, ideally by someone independent.

Photos and video from before repairs began, and any from before the loss
A written report from a contractor, engineer or mechanic who inspected the damage
Weather records for the date and county of a storm
Invoices, repair records and maintenance logs that date the problem
Your claim log: each call, email and inspection, with dates and names

For hail or wind, NOAA's Storm Events Database lets you search reported storms by county. Records are added about 75 to 90 days after the end of each month⁵, so for a recent storm NOAA points you to its Storm Prediction Center instead.

Write the appeal letter section by section

United Policyholders says letters to an insurer should not be threatening or lengthy⁶, but clear, polite and to the point. A supervisor or regulator may read yours later, so write for them too.

The seven sections of the template's letter

Section	What goes in it	Mistake to avoid
1. What happened	Two to four sentences of dated fact	Arguing coverage before stating the facts
2. Reason for the denial	The insurer's words, quoted, with page and paragraph	Paraphrasing it into something easier to answer
3. Policy language	The coverage grant and the full provision cited, with form and page	Quoting only the part in the denial
4. Response to each reason	The quote, why it doesn't apply, and the exhibit	Answering the strongest reason and skipping the rest
5. Evidence enclosed	Each exhibit by letter, with its date	Sending originals you can't replace
6. What I am asking for	Reversal, an amount less the deductible, and written reasons for anything upheld	Asking them to "take another look"
7. Response requested	A date for a written answer	A date that ignores your state's rules

Check before it goes out

Every reason has its own row in the map and its own answer in the letter
Each quote matches the denial or the policy word for word, with a page number
Anything the insurer didn't decide is listed and claimed
Every exhibit is lettered, dated and mentioned in the text
The amount asked for is net of the deductible and matches your estimate
The reply date fits your state's rules, and your notes to yourself are deleted

Send the appeal, then watch the deadlines

Send it in a way that proves the date. United Policyholders suggests certified mail for any letter that asks for a reply by a set date⁶. It also suggests copying the adjuster's supervisor and calling to confirm the letter arrived.

Find the policy's time limit to sue, usually a condition called "Suit Against Us" or "Legal Action Against Us," and put the date on your calendar. An appeal may not pause it.

If the insurer stands by its decision or goes quiet, you can complain to your state insurance department, or hire a licensed public adjuster or a lawyer. The NAIC says departments can investigate unfair claim delays or denials for free⁷. They forward each complaint to the insurer, which must respond with its explanation.

When a lawyer should see it first

Get a lawyer licensed in your state to review the letter first if the claim is large or the time limit to sue is close. An accusation of misrepresentation, or a demand for a sworn statement, is another reason. This guide is general information about US claims, not legal advice.

Common questions

Can you appeal a denied insurance claim?

Yes. With a home, auto or business policy, you ask the insurer in writing to reconsider and answer each reason it gave with the policy's own wording and your evidence. Health plans use a formal internal appeal and external review instead. If the insurer still says no, your state insurance department takes complaints at no charge.

How long does an insurer have to respond to an appeal?

It depends on your state. The NAIC's model regulation, which states can adopt in their own form, asks insurers to reply within 15 calendar days² to a claimant's letter that reasonably calls for a response. A reply isn't always a decision. Check your state's rule and any deadline in the denial letter before you set the reply date your letter asks for.

What if the insurer paid, but not enough?

Then you're disputing the amount rather than the coverage, so a supplemental claim fits better than an appeal. Compare the insurer's estimate with your contractor's line by line and claim the difference. Also check whether your policy has an appraisal clause, which settles disagreements over the amount of a loss.

Is this template legal advice?

No. It helps you set out the facts, the policy wording and your evidence clearly, but it doesn't decide whether your loss is covered. For a large or complicated claim, have a lawyer licensed in your state, or a licensed public adjuster, review the letter before you send it.

Is this insurance claim appeal letter template free?

Yes. Download the Word letter and the CSV Denial Reason Map with no account. Every blank is in square brackets, and the notes to you are marked for deletion before you send. To have River fill both from your own documents, start in the box at the top of this page.
