Insurance Claim Denied? How to Appeal and Win
Insurance company denied your claim? Learn why denials happen, your legal rights, how to write a winning appeal letter, and when to escalate to your state's insurance commissioner.
An insurance denial letter is not the final word. Insurance companies deny claims for many reasons — some legitimate, many not. The appeal process exists precisely because denials are frequently wrong, and insurers count on policyholders not knowing how to fight back. A well-written appeal, citing your policy language and state law, overturns denials at a significant rate. Here's exactly how to do it.
Why Insurance Companies Deny Claims
Common denial reasons — and the truth behind them:
Exclusion cited: The insurer claims your loss falls under a policy exclusion. Sometimes valid; often stretched beyond the exclusion's actual language.
'Pre-existing condition': For health insurance, conditions that existed before coverage began. The ACA eliminated pre-existing condition exclusions for ACA-compliant individual and small group plans, but they still apply in some limited health plans.
Late filing: You filed the claim after the deadline stated in your policy. Many people don't realize claims have filing deadlines — often 30–90 days from the date of loss.
Coverage lapse: Your policy lapsed due to a missed payment. Many states require a grace period and specific notice before cancellation. If proper notice wasn't given, the policy may still be in force.
'Gradual damage' or 'wear and tear' exclusion: Common in homeowners claims. The insurer claims the damage happened over time, not suddenly. This is one of the most contested denial reasons.
Lack of documentation: The insurer says you didn't provide enough proof of the claim or the loss amount.
Your Rights Under Your Policy and State Law
Your insurance policy is a contract. The insurer must honor it. But you also have rights beyond the policy itself:
Right to a written denial explanation: Insurers must provide a written denial letter specifying the reason and the policy provision they're relying on. If you received a vague denial, request a detailed written explanation citing the exact exclusion or policy language.
Right to an internal appeal: All health insurance plans must have an internal appeal process. For other lines (home, auto, life), you can typically request a formal reconsideration in writing.
Right to an external review (health insurance): After exhausting internal appeals, you're entitled to an independent external review by a third party. The external reviewer's decision is binding on the insurer in most states.
Bad faith protections: If the insurer unreasonably denies a valid claim, delays payment without cause, or fails to investigate properly, they may be liable for bad faith damages — which can exceed the original claim value, including punitive damages in some states.
How to Read Your Denial Letter
The denial letter should contain:
- The specific policy provision, exclusion, or condition the insurer is citing
- The facts they relied on to make the decision
- Your deadline to appeal (typically 30–180 days depending on policy and state law)
- Instructions for how to appeal
Read the cited policy provision yourself. Insurers sometimes misquote or broadly interpret exclusions. If the exclusion language is ambiguous, courts generally interpret it in the policyholder's favor under the doctrine of 'contra proferentem' — the insurer drafted the contract, so ambiguity goes against them.
How to Write an Insurance Claim Appeal Letter
Your appeal letter should:
State the facts: Date of loss, what happened, what was damaged or what medical treatment was received, the claim number, the denial date.
Quote your policy: Find the coverage provision that supports your claim and quote it directly. 'Section IV, Coverage A of my policy states: [quote]. My claim falls within this coverage because...'
Refute the denial reason: Address the specific reason for denial. If they cited an exclusion, explain why it doesn't apply to your specific facts. If they claimed gradual damage, provide evidence of a sudden event.
Attach supporting documentation: Photos, repair estimates, contractor statements, medical records, expert opinions, weather data, police reports — anything that supports your claim.
Request a specific outcome: 'I request that you reverse your denial decision and process my claim for $[amount] within 30 days.'
Reference state law if applicable: Many states have specific claim handling regulations with deadlines that bind the insurer.
State Insurance Commissioner: Your Regulator
Every state has an Insurance Commissioner or Department of Insurance that regulates insurers. Filing a complaint triggers an investigation.
When to file: After your internal appeal is denied, or if the insurer is taking an unreasonably long time to respond.
What it does: The commissioner contacts the insurer on your behalf. Insurers take regulatory complaints seriously — a pattern of complaints can result in fines or license suspension. Many complaints result in the insurer reconsidering and paying the claim.
How to file: Visit your state's Department of Insurance website and search for 'file a complaint.' You can typically file online.
Find your state's department: naic.org/state_web_map.htm — the National Association of Insurance Commissioners has links to all state departments.
External Review for Health Insurance Denials
Under the ACA, you have the right to an independent external review if your health insurance internal appeal is denied. The external reviewer — a licensed medical professional not employed by the insurer — makes a binding decision.
Eligibility: You must first exhaust the insurer's internal appeal process (or the insurer must fail to meet its own appeal deadlines). Applies to most denials based on medical necessity or experimental treatment.
Cost: Free to you. The insurer pays the review organization.
Timeframe: Standard external review: 45 days. Expedited (urgent medical situations): 72 hours.
Reversal rate: Independent external reviews overturn insurer decisions approximately 40% of the time nationally, with rates as high as 60% in some states.
How to request: Your denial letter must include instructions. If not, call your state insurance department.
Bad Faith Insurance Practices
Insurance bad faith is when an insurer unreasonably denies or delays a valid claim, or fails to properly investigate. This is more than just being wrong — it's a failure to honor the implied duty of good faith and fair dealing.
Examples of bad faith:
- Denying a claim without investigating
- Offering a settlement far below the claim's value without justification
- Delaying payment unreasonably after the claim is approved
- Misrepresenting policy provisions to deny a claim
Bad faith remedies vary by state but can include: the original claim amount, consequential damages (costs you incurred because of the denial), emotional distress damages, and punitive damages. Some states allow attorney fee recovery.
Consult an attorney specializing in insurance bad faith if you believe your claim was denied in bad faith. Many work on contingency.
Frequently Asked Questions
Quick answers to the most common questions on this topic.
How long do I have to appeal an insurance denial?
+
For health insurance, ACA-compliant plans must give you at least 180 days to file an internal appeal. For homeowners, auto, and life insurance, deadlines are in your policy — typically 60–180 days from the denial date. Never miss this deadline.
Can I sue my insurance company for denying my claim?
+
Yes. If the denial violates your policy or constitutes bad faith, you can sue. For large claims or bad faith situations, consult an insurance attorney. Many work on contingency and can assess whether you have a viable case for free.
What is an independent medical review?
+
For health insurance, an IMR (or external review) is a review by an independent licensed medical professional of the insurer's medical necessity determination. It's available after exhausting internal appeals. Binding on the insurer in most states.
What if my insurer won't respond to my appeal?
+
File a complaint with your state's Department of Insurance. Insurers have legally required response timeframes for appeals — typically 30–60 days. Failure to respond can be a regulatory violation.
Does filing a claim raise my insurance rates?
+
Potentially, yes — filing a claim can trigger a rate increase at renewal or non-renewal. This is why some policyholders pay smaller losses out of pocket. Check your policy and ask your agent before filing.
