How Uninsured Motorist Coverage, PIP and MedPay Work After a Car Crash
By @damiennuxl250
After a car crash, more than one insurance policy may apply. The at-fault driver's liability coverage is usually the first source people think of, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. A car accident attorney usually requests the declarations page for every policy that might apply, because the coverage often decides how much of a loss can be paid.
How fault rules shape coverage
Most states require drivers to carry a minimum amount of liability insurance, which covers injuries and property damage the insured driver causes to others. Minimum limits are often 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. A smaller group of states uses a no-fault system, where each driver's own PIP coverage pays medical expenses and some lost income regardless of who caused the crash. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
How PIP and MedPay work
No-fault states require PIP, and a few other states do as well, while some states offer it as an option. Depending on the policy, it may cover medical bills, a share of lost wages and some household expenses. Medical payments coverage, usually called MedPay, is separate and generally smaller. https://jeffreyjgbb966.sagecurrent.com/posts/diminished-value-and-other-car-crash-insurance-issues-2 It pays medical expenses for the policyholder and passengers regardless of fault, up to the limit on the policy. An auto accident attorney will check whether these benefits require prompt notice or a written claim.
Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage applies when the at-fault driver 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 for stacking coverage from several vehicles or policies also vary by state. A relative's policy in the same household may also provide UM coverage in some states.
Making a UM claim
A UM claim is made to the injured person's own insurer, 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 hit-and-run claims may depend on a timely police report. In some states, the UM insurer must be served with a copy of any lawsuit against the at-fault driver. A car crash attorney usually checks these steps early, since a missed step can put coverage at risk.
Coverage for the car itself
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. Gap insurance and rental reimbursement are optional coverages that can matter after a total loss.
Health insurance and liens
Medicare, Medicaid or a health plan may pay medical bills first and later seek repayment from a settlement. An automobile accident lawyer usually resolves these liens before funds are distributed. Coverage rules differ by state and by policy, and this is general information rather than legal advice.
