Insurance Claim Denied? How to Appeal, Complain and Push Back

A denial isn’t always the last word. Start by getting the company’s reasons in writing and checking them against your policy. If you still disagree, ask the company to reconsider with better evidence, and if that fails, file a complaint with your state insurance department, which regulates how insurers handle claims [1][2]. Keep an eye on deadlines the whole time, because some are short.

At a glance

First step: Get the reason for the denial in writing [1][13]
Who regulates claims: Your state insurance department [1][2]
Rules insurers must follow: State unfair claims practices laws, many based on an NAIC model [3]
Where to get help: State consumer services staff and complaint process [1][2]
Health claims: 180 days for an internal appeal, then external review [10][11]

Step 1: Read the denial letter

Ask for the company’s reasons in detail and in writing if you only got a phone call [13]. A good denial letter tells you three things: what was denied, why, and which part of the policy the company relies on. Some states spell this out. In California, for example, a written denial must list every reason for it, cite the specific policy provision or law it relies on, and tell you that you can have the matter reviewed by the California Department of Insurance [4]. Florida requires insurers to give written notice when an auto claim is denied [5].

Look for the type of denial, because each calls for a different response:

Not covered. The company says the loss falls outside the policy or under an exclusion.
Not proven. It says it lacks proof of the loss, its cause or its amount.
Late or incomplete. It says you missed a notice deadline or didn’t send what it asked for.
Disputed amount. The claim is accepted, but the company offers less than you think it’s worth.

Step 2: Read the policy yourself

Get a complete copy of your policy, including the declarations page and every endorsement, and find the section the denial cites. Read the definitions, since a single defined word can decide a claim. Also read the Conditions section, which sets your duties after a loss, such as giving notice and documenting the damage, and any time limits the policy sets.

If the dispute is only about the amount of a property claim, check whether the policy has an appraisal clause [1].

Step 3: Ask the company to reconsider

For auto, home and other property claims, the next step is asking the company to take another look. Write a letter that:

names the claim number and the denial date,
explains, point by point, why the reasons in the denial are wrong,
quotes the policy language that supports you, and
attaches proof: photos or videos of the damage, repair estimates, receipts, police or fire reports and medical records.

State regulators suggest photographing damage before repairs, keeping all repair receipts and following up phone calls with an email or letter [9]. If the company says you didn’t prove your loss, you must give it documentation to back up a request for more money [5]. Ask the adjuster for an explanation of any decision or offer [9], and if that doesn’t work, ask to speak with a supervisor.

Step 4: File a complaint with your state insurance department

If you still disagree, ask for help from the consumer services staff at your state insurance department [1]. The NAIC lists each state’s department and how to file a complaint with it [2]. In Florida, for example, the Department of Financial Services runs the Insurance Consumer Helpline at 1-877-693-5236 and offers mediation for some disputed auto claims [5].

The rules insurers have to follow

States regulate claim handling through unfair claims settlement practices laws. The NAIC’s model version lists practices that an insurer can’t commit flagrantly or as a general business practice, including [3]:

knowingly misrepresenting the facts or policy provisions,
failing to acknowledge communications about a claim with reasonable promptness,
refusing to pay claims without a reasonable investigation,
failing to affirm or deny coverage within a reasonable time after investigating,
not trying in good faith to settle promptly and fairly once liability is reasonably clear,
forcing policyholders to sue by offering substantially less than they ultimately recover, and
failing to promptly give a reasonable explanation for a denial or a compromise offer.

Under the model law, the state insurance commissioner enforces these rules, with penalties up to suspending or revoking the insurer’s license [3].

Bad faith

“Bad faith” is the general term for an insurer that unreasonably fails to honor its policy. Whether you can sue for it, and how, depends on your state. The NAIC’s model law says it doesn’t create a private right to sue [3], but some states have created separate remedies. Florida, for example, lets policyholders sue for certain violations, but only after filing a civil remedy notice with the Department of Financial Services and the insurer, and no suit may go forward if the insurer pays the damages or fixes the violation within 60 days [8].

Deadlines that matter

Deadlines run on both sides. Your policy has its own notice and proof-of-loss requirements, and state law sets more. Florida is one example for home and other property claims. An insurer there must pay or deny a claim within 60 days of notice [6], and you must report a new claim within 1 year of the date of loss [7]:

Florida property insurance claim deadlines (an example)
Deadline	Time limit
Insurer acknowledges your communication about a claim	7 calendar days [6]
Insurer begins investigating after proof-of-loss statements	7 days [6]
Insurer pays or denies the claim	60 days after notice of the claim [6]
You give notice of a new or reopened claim	1 year after the date of loss [7]
You give notice of a supplemental claim	18 months after the date of loss [7]
Insurer gets to fix a problem after a civil remedy notice	60 days [8]

If it’s a health insurance claim

Health claims follow different, federal rules. Under the Affordable Care Act’s appeal rules [12]:

Appealing a denied health insurance claim
Step	Deadline
You file an internal appeal with the insurer	Within 180 days of the denial notice [10]
Insurer decides an appeal for care you haven't received yet	30 days [10]
Insurer decides an appeal for care you already received	60 days [10]
You ask for an independent external review	Within 4 months of the final denial [11]
Standard external review decision	Up to 45 days [11]
Expedited external review for urgent cases	72 hours or less [11]

In an external review, an independent reviewer decides, and the insurer has to accept the result [11]. The review is free under the federal HHS-run process, and other processes can charge no more than $25 [11].

When to get a lawyer

Many denials are settled with better paperwork and a complaint. People commonly bring in an attorney when the claim is large, when the company says the loss isn’t covered at all, when a deadline to sue is getting close, or when they think the company is acting in bad faith. This guide is general information, not legal advice; for your own claim, consult a licensed attorney in your state.

Common questions

What should I do first when my insurance claim is denied?

Get the reason in writing and read it next to your policy. Find the exact policy provision the company relies on, then check whether the facts it used are right. Many denials turn on a missing document or a misunderstanding that can be fixed.

Where do I file a complaint against an insurance company?

With your state's insurance department. The NAIC, the national association of state insurance regulators, lists every state's department and how to file a complaint with it.

Can I sue my insurance company for bad faith?

It depends on your state. The NAIC's model law on unfair claims practices says it doesn't itself create a right to sue, but some states give policyholders a separate remedy. Florida, for example, requires a civil remedy notice and gives the insurer 60 days to fix the problem first. Ask a licensed attorney in your state.

How long do I have to appeal a denied health insurance claim?

Under federal rules, you have 180 days from the denial notice to file an internal appeal. If the insurer still says no, you generally have 4 months to ask for an independent external review.
