Uninsured Motorist Claim Denied? How to Appeal and Get Paid
If your uninsured or underinsured motorist claim was denied, you have options. Learn why UM/UIM claims are rejected and how to fight back through appeal.
Uninsured Motorist Claim Denied? How to Appeal and Get Paid
You did everything right — you purchased uninsured motorist (UM) or underinsured motorist (UIM) coverage specifically to protect yourself in case you're hit by a driver with no insurance or inadequate coverage. Then when you need it most, your own insurer denies the claim. This is one of the most frustrating insurance situations a driver can face, and unfortunately it's more common than it should be.
How UM/UIM Coverage Works
Uninsured motorist coverage pays for your bodily injury — and sometimes property damage — when you're hit by a driver who has no insurance. Underinsured motorist coverage kicks in when the at-fault driver has insurance, but their limits are too low to cover all your damages. Both types of coverage essentially step into the shoes of the at-fault driver's liability insurance.
Most states require insurers to offer UM/UIM coverage; many require you to carry it unless you specifically reject it in writing.
Why UM/UIM Claims Are Denied
Dispute about fault. Your own insurer takes the position of the at-fault driver when evaluating a UM/UIM claim. They have a financial incentive to minimize your recovery, and they may dispute that the uninsured driver was at fault, or argue that you contributed to the accident.
Failure to identify the at-fault vehicle. For a hit-and-run or phantom vehicle claim, most policies and many states require some corroboration that another vehicle was actually involved. If there are no witnesses and no physical evidence, the insurer may deny the UM claim on the basis that the accident cannot be verified.
Arbitration clause and procedural issues. Many UM/UIM policies require disputes to be resolved through arbitration rather than litigation. Failure to follow specific procedural requirements — such as properly invoking arbitration within the required timeframe — can be used to deny or complicate the claim.
Offset by other available insurance. Insurers sometimes argue that your damages are fully covered by the at-fault driver's (minimal) coverage or by your MedPay/PIP coverage, and that no UM/UIM benefits remain owed.
Stacking limitations. In states that prohibit stacking of UM/UIM policies, you can only access the limits of one policy. If you expected to combine limits across multiple vehicles, the insurer may deny the additional benefits.
Medical causation disputes. If your injuries are disputed — the insurer argues they predate the accident, are exaggerated, or are unrelated — they may deny or minimize the bodily injury component of your UM/UIM claim.
Policy exclusions. Some policies exclude UM/UIM coverage in specific circumstances, such as when you are occupying a vehicle not insured on the policy.

How to Appeal a Denied UM/UIM Claim
Gather all accident evidence. Police reports, photos, witness statements, dashcam footage, traffic camera records, and any physical evidence of the other vehicle's involvement are crucial for hit-and-run claims.
Document your injuries thoroughly. Medical records, treatment notes, physical therapy records, and doctor's opinions on the cause and extent of your injuries directly counter medical causation disputes.
Get an independent medical examination (IME) if needed. If the insurer's IME doctor produced a report minimizing your injuries, you can obtain your own expert medical opinion.
Review your state's UM/UIM laws. UM/UIM law varies significantly by state. Some states prohibit insurers from applying certain offsets; others require arbitration; some allow direct lawsuits. Know your rights under your state's law.
File a formal internal appeal. Submit a written appeal with all supporting documentation within the timeframe specified by your insurer — typically 30–60 days for auto claims.
Demand arbitration if required. Many UM/UIM policies require binding arbitration to resolve disputes. If arbitration is available, it can be more efficient than litigation and often produces fairer outcomes than initial claims decisions.
File a complaint with your state Department of Insurance. Your state's insurance regulator can investigate whether your insurer improperly denied a valid UM/UIM claim.
Consult an auto insurance attorney. UM/UIM bad faith cases are well-recognized in most states. An insurer that unreasonably denies a valid UM/UIM claim can face liability for the full claim amount, attorney's fees, and consequential damages.
State Considerations
- California: UM/UIM claims are governed by Insurance Code sections 11580.2 et seq. Insurers must conduct a fair investigation and cannot arbitrarily deny claims.
- Florida: Florida is a no-fault state, which affects how UM/UIM claims interact with PIP benefits.
- Texas: The Texas Prompt Payment of Claims Act imposes strict deadlines on insurers handling UM/UIM claims.
- New York: UM/UIM disputes are resolved through SUM arbitration administered by the American Arbitration Association.
