How Uninsured Motorist Coverage, PIP and MedPay Work After a Car Crash

After a car crash, more than one insurance policy may apply. People usually think first of the at-fault driver's liability coverage, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. An auto accident lawyer will usually ask for the declarations page of every policy that might apply, since coverage often decides how much of a loss can be paid.
At-fault and no-fault states
Most states require drivers to carry a minimum amount of liability insurance, which pays for injuries and property damage the insured driver causes to others. State minimum limits can be low compared with the cost of a serious injury. In at-fault states, the injured person generally claims against the at-fault driver's insurer. Some states use a no-fault system, in which each driver's own PIP coverage pays medical expenses and some lost income regardless of fault. In those states, a lawsuit against the at-fault driver may be limited unless the injury meets a legal threshold.
PIP and MedPay coverage
PIP https://lanebtwq637.tearosediner.net/which-insurance-pays-after-a-car-accident-uninsured-motorist-pip-and-medpay is required in no-fault states and in a few other states, while some states offer it as an option. Depending on the policy, it can pay medical bills, part of lost wages and certain household expenses. Medical payments coverage, usually called MedPay, is separate and generally smaller. The coverage pays medical expenses for the policyholder and passengers no matter who caused the crash, up to its policy limit. A car crash lawyer will check whether these benefits require prompt notice or a written claim.
Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage pays for injuries caused by a driver who has no insurance, and many states extend it to hit-and-run crashes. Underinsured motorist (UIM) coverage applies when the at-fault driver's limits fall short of the loss. Some states require UM coverage, and others let a policyholder reject it in writing. Rules on stacking coverage from more than one vehicle or policy also vary. A relative's policy in the same household may also provide UM coverage in some states.
Making a UM claim
The UM claim goes to the injured person's own insurance company, yet in that claim the insurer stands in the shoes of the uninsured driver, so it may dispute fault and the amount of damages. Many policies require prompt notice, and a hit-and-run claim may require a timely police report. Some states require that the UM insurer be served with a copy of the lawsuit against the at-fault driver. A car crash attorney will check these requirements early, since a missed step can put coverage at risk.
Vehicle damage coverage
Collision coverage pays for repairs to the policyholder's car regardless of fault, less the deductible. The insurer may then seek repayment from the at-fault driver's insurer through subrogation, which can sometimes recover the deductible as well. Rental reimbursement and gap insurance are optional coverages that can matter after a total loss.
Health plans and repayment
Medicare, Medicaid or a health plan may pay medical bills first and later seek repayment from a settlement. An automobile accident lawyer will usually resolve those liens before any money is distributed. Coverage rules differ by state and by policy, and this article is general information, not legal advice.
