Dear Appeals Department:
I am writing to formally appeal the denial of the above-referenced claim. I received your denial letter dated [date] in which you stated that [briefly quote or summarize the specific denial reason from the letter].
I am requesting that [Insurance Company Name] reverse this denial and pay the claim in full, for the following reasons:
1. The denial reason does not apply to the facts of this claim.
[Explain in 1-3 paragraphs why the insurer’s stated reason for denial is incorrect as applied to your specific situation. Reference the policy language by section number and quote it directly where helpful. Be factual and specific — avoid emotional appeals.]
2. Supporting evidence demonstrates the claim is covered.
[List your supporting documentation with specifics — for example: “A letter of medical necessity from Dr. [Name], dated [date], establishes that the requested treatment is appropriate for my diagnosis of [condition].” Or for property: “An independent estimate from [Contractor Name], dated [date], documents [findings].”]
3. The policy language supports coverage.
[Cite the specific policy section(s) that support coverage. If the insurer cited an exclusion, point to the exclusion’s exception clause or to the coverage section that the loss falls under. Direct quotes from the policy are most effective.]
Documentation enclosed:
- Copy of denial letter dated [date]
- Policy declarations page
- [List each piece of supporting evidence numerically]
- [...]
Requested relief: I respectfully request that [Insurance Company Name] reverse the denial and process payment of this claim in full, in the amount of [$X if applicable], within the time period required by [my state’s] insurance regulations.
I am prepared to pursue further review through your external review process and, if necessary, through my state Department of Insurance. I would prefer to resolve this matter at the internal-appeal level and look forward to your response within the timeframe required by [the ACA / my state’s applicable insurance regulations].
Please confirm receipt of this appeal and provide the expected timeline for the decision. You may contact me at [phone] or [email].
Sincerely,
[Your Signature]

Tips for an effective appeal
- → Be specific and factual. Identify exactly which denial reason you’re appealing and which evidence rebuts it.
- → Quote policy language directly. Don’t paraphrase — exact quotes carry more weight.
- → Address the insurer’s specific reasoning, not generic appeals. A boilerplate appeal is the easiest to deny.
- → Keep emotional content minimal. Adjusters and reviewers respond better to evidence than to frustration.
- → Get treating physician support for health appeals. A letter of medical necessity from your doctor is the single most valuable evidence for medical-necessity denials.
- → Get independent expert support for property appeals. Independent contractor estimates, engineer reports, or inspector reports counter the insurer’s adjuster estimate.
- → Send via certified mail with return receipt OR keep digital confirmation if submitting through a portal.
- → Track the deadline for the insurer’s response — if they don’t respond on time, that itself becomes a regulatory issue.
