While this list isn’t exhaustive, small business insurance claims could get denied for many reasons. Denials on filed claims can stem from specific policies of an insurer, how a policy is underwritten and other claim circumstances. These reasons are some of the more common that we’ve seen.
1. You don’t have the right insurance coverage
A claim may be denied if a business doesn’t have the right insurance coverage for a specific incident.
For example, many business owners use their personal vehicles when driving for work, such as a realtor who shows homes or a contractor driving between jobs.** If the driver has personal auto insurance but not commercial auto insurance and they get into an accident, their claim could be denied by the insurance company because they were driving for professional reasons vs. personal.
In addition, insurance policies could have specific exclusions that narrow the scope of your coverage.
To help prevent denial: Read your policy thoroughly with your agent, broker or insurance company to understand the exclusions and coverages for your business’ risks. Consider endorsements (add-on coverages) to help close any gaps in protection.
2. There’s incorrect or missing information on your claim
Something as simple as a typo could trigger a denial. Claims submitted with errors, such as incorrect spelling, inverted policy numbers or inaccurate dates could also be denied.
Missing info could also be an issue. To help move your claim forward, be sure you’ve included all of the information requested.
To help prevent denial: Meticulously review all your claim forms and supporting documents before submitting them. Double-check all your business and policy information and include all requested documentation.
3. You missed the filing deadline
Commercial insurance policies often have a time limit they set themselves or set by the state within which claims must be filed. And insurers usually strictly enforce these deadlines.
Submitting a claim after the deadline can result in a denial.
To help prevent denial: Make a note of all relevant filing deadlines and submit your claims as early as possible. Confirm submission deadlines directly with your insurer.
4. You didn’t adhere to policy terms and conditions
When you buy insurance for your business, you agree to the conditions outlined in your insurance policy. This could include things like maintaining safety standards, following proper operational procedures or cooperating with the insurer in the event of a claim. If you fail to meet these specific policy requirements, your claim could be denied.
For example, if your commercial property insurance coverage requires that an insurer-approved contractor complete repairs, a claim for work performed by an unapproved contractor may be denied.
To help prevent denial: Make sure you understand all of your insurer’s requirements for safety standards, signage, policies and procedures. Contact your insurer if you have any doubts to ensure you’re fully compliant with your policy terms.
5. The claim wasn’t an operational necessity
Insurers may deny coverage for a business-related claim if they determine that the expense isn’t essential for maintaining business continuity.
For example, if a retail store submits a claim for extensive cosmetic upgrades — such as high-end decorative finishes or elaborate storefront signage — after a covered loss, the insurer might argue that only necessary repairs to restore safe and functional operation are eligible.
While beneficial for appearance, cosmetic improvements are not typically considered operationally necessary.
To help prevent denial: When filing a claim, include detailed expert assessments, repair reports or loss analyses that help prove the expense is necessary to keep your business running.
6. You didn’t get prior authorization
Some commercial insurance policies may require prior authorization for some services or special equipment. For example, workers’ compensation insurance policies may require pre-approval for some medical treatments or surgeries for work-related injuries.
Say, for example, an injured employee needs orthopedic surgery but the treatment isn’t pre-approved. The claim may be denied — even if the surgery is later deemed necessary.
To help prevent denial: Before incurring significant expenses, contact your insurer to verify if they require prior authorization. It’s best to get written confirmation and retain all related correspondence to support your claim if there are disputes.
7. Your business had undisclosed pre-existing conditions
You may associate pre-existing conditions with health insurance, but it can also apply to historical issues like a claims history or known operational vulnerabilities in business insurance.
For example, a restaurant with a history of recurring water damage from an aging roof may face exclusions, reduced coverage or a higher premium for similar future incidents. But if there’s an event with the roof and you’ve not told your insurer about previous roof problems, your claim could be denied, and your policy could even be rescinded.
To help prevent denial: Fill out your insurance application truthfully and accurately. Work with your insurer to develop a policy that accurately reflects your business risk. Maintain thorough records of past claims and repairs in case you need to support future claims.
8. The claim was flagged for fraud or misrepresentation
Commercial insurers use rigorous fraud detection systems to review claims. Even minor inaccuracies or discrepancies in documentation can raise concerns, potentially leading to claim denials. Insurers may interpret incomplete or inconsistent information as misrepresentation, whether intentional or accidental.
To help prevent denial: Always double-check your claim submission for accuracy and completeness. Ensure that all documents are supported by reliable evidence (e.g., detailed invoices, photos or communications) to prevent triggering fraud alerts that could delay or deny your claim.
9. You didn’t submit sufficient supporting documentation
Commercial claims may get denied if supporting documentation is incomplete or missing.
If things like invoices, repair estimates, independent assessments or detailed loss reports are not provided when you submit your claim, the insurer might reject you due to a lack of evidence to substantiate the loss or expense.
To help prevent denial: Maintain a well-organized digital archive of all relevant documents — invoices, photographs, repair estimates and correspondence. When filing a claim, attach every required piece of evidence to build a strong, verifiable case for your loss.
